With the right setup, an application can go from serving a few users to millions effortlessly. Setting up Kubernetes can be tasking and can require a lot of expertise to put all the pieces together. You’ll need to set up virtual or bare metal machines to use as nodes and manage SSL certificates, networking, load balancers, and many other moving parts.\n\nThe introduction of Amazon Elastic Kubernetes Service (EKS) was widely applauded as it streamlines the abstraction of the complexities in an environment most organizations are already familiar with and on a provider they already trust. Amazon EKS makes creating and managing Kubernetes clusters easier with more granular controls around security and straightforward policies of how resources are used.\n\nGitLab strives to increase developer productivity by automating repetitive tasks and allowing developers to focus on business logic. We recently introduced support for auto-creating Kubernetes clusters on Amazon EKS. In a few clicks with the right permissions, you’ll have a fully functional Kubernetes cluster on Amazon EKS. It doesn’t stop there however – GitLab also gives you the power to achieve the following use cases and more :\n\n* [Highly scalable CI/CD system using GitLab Runner](https://docs.gitlab.com/runner/): There are times like holidays when little to no changes to code are pushed to production, so why keep resources tied down? With the Amazon EKS integration with GitLab, you can install GitLab Runner with just a click and your CI/CD will run effortlessly without worrying about running out of resources.\n* Shared Cluster: Maintaining multiple Kubernetes clusters can be a pain and capital intensive. With Amazon EKS, GitLab allows you to setup a cluster at [Instance](https://docs.gitlab.com/ee/user/instance/clusters/index.html), [Group](https://docs.gitlab.com/ee/user/group/clusters/index.html) and [Project](https://docs.gitlab.com/ee/user/project/clusters/) levels. Kubernetes Namespaces are created for each GitLab project when the Amazon EKS is integrated at Instance and Project level, allowing isolation and ensuring security.\n* [Review Apps](https://docs.gitlab.com/ee/ci/review_apps/index.html): Reviewing changes to code or design can be tricky, you’ll need to check out your branch and run the code in a test environment. GitLab integrated with Amazon EKS deploys your app with new changes to a dynamic environment and all you need to do is click on a “View App“ button to review changes.\n* [AutoDevOps](https://docs.gitlab.com/ee/topics/autodevops/cloud_deployments/auto_devops_with_gke.html) takes DevOps to a whole new level. AutoDevOps detects, builds, tests, deploys, and monitors your applications, leveraging the Amazon EKS integration. All you have to do is push your code and the magic happens. In this tutorial, we will deploy a sample application to the Amazon EKS cluster we will be creating using AutoDevOps.\n\nTo show you how easy it is to create an Amazon EKS cluster from GitLab, the rest of this tutorial will walk you through the steps of the integration, starting with a one-time setup of necessary resources on AWS.\n\n## One-time setup on AWS to access resources\n\nFirst, we need to create a “provision\" role and a “service” role on AWS to grant GitLab access to your AWS resources and set up the necessary permissions to create and manage EKS clusters. You only need to perform these steps once and you can reuse them anytime you want to perform another integration or create more clusters.\n\n### Step 1 - Create Provision Role\n\nTo grant GitLab access to your AWS resources, a “provision role” is required. Let’s create one:\n\n1. Access GitLab Kubernetes Integration Page by clicking on the ”Kubernetes” menu for groups and Operations > Kubernetes menu for projects and click the “Add Kubernetes Cluster” button.\n2. Select “Amazon EKS” in the options provided under the “Create new cluster on EKS” tab.\n3. You are provided with an Account and External ID  to use for authentication. Make note of these values to be used in a later step.\n\n    ![Gitlab EKS Integration Page](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/gitlab_eks_integration_page.png)\n\n4. Open IAM Management Console in another tab and click on “Create Role”\n5. Click on the “Another AWS account” tab and provide the Account and External ID obtained from GitLab and click Next to set permissions as shown below:\n\n    ![AWS Provision Role](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/provision_role.png)\n\n6. On the permissions page, click on “Create policy.” This will open a new tab where you can set either of the permissions below using JSON:\n\n    ```json\n    {\n        \"Version\": \"2012-10-17\",\n        \"Statement\": [\n            {\n                \"Effect\": \"Allow\",\n                \"Action\": [\n                    \"autoscaling:*\",\n                    \"cloudformation:*\",\n                    \"ec2:*\",\n                    \"eks:*\",\n                    \"iam:*\",\n                    \"ssm:*\"\n                ],\n                \"Resource\": \"*\"\n            }\n        ]\n    }\n    ```\n\n    This gives GitLab full access to create and manage resources, as seen in the image below:\n\n    ![AWS Role Policy](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/create_role_policy.png)\n\n    If you prefer limited permission, you can give GitLab the ability to create resources, but not delete them with the JSON snippet below. The drawback here is if an error is encountered during the creation process, changes will not be rolled back and you must remove resources manually. You can do this by deleting the relevant CloudFormation stack.\n\n    ```json\n    {\n        \"Version\": \"2012-10-17\",\n        \"Statement\": [\n            {\n                \"Effect\": \"Allow\",\n                \"Action\": [\n                    \"autoscaling:CreateAutoScalingGroup\",\n                    \"autoscaling:DescribeAutoScalingGroups\",\n                    \"autoscaling:DescribeScalingActivities\",\n                    \"autoscaling:UpdateAutoScalingGroup\",\n                    \"autoscaling:CreateLaunchConfiguration\",\n                    \"autoscaling:DescribeLaunchConfigurations\",\n                    \"cloudformation:CreateStack\",\n                    \"cloudformation:DescribeStacks\",\n                    \"ec2:AuthorizeSecurityGroupEgress\",\n                    \"ec2:AuthorizeSecurityGroupIngress\",\n                    \"ec2:RevokeSecurityGroupEgress\",\n                    \"ec2:RevokeSecurityGroupIngress\",\n                    \"ec2:CreateSecurityGroup\",\n                    \"ec2:createTags\",\n                    \"ec2:DescribeImages\",\n                    \"ec2:DescribeKeyPairs\",\n                    \"ec2:DescribeRegions\",\n                    \"ec2:DescribeSecurityGroups\",\n                    \"ec2:DescribeSubnets\",\n                    \"ec2:DescribeVpcs\",\n                    \"eks:CreateCluster\",\n                    \"eks:DescribeCluster\",\n                    \"iam:AddRoleToInstanceProfile\",\n                    \"iam:AttachRolePolicy\",\n                    \"iam:CreateRole\",\n                    \"iam:CreateInstanceProfile\",\n                    \"iam:CreateServiceLinkedRole\",\n                    \"iam:GetRole\",\n                    \"iam:ListRoles\",\n                    \"iam:PassRole\",\n                    \"ssm:GetParameters\"\n                ],\n                \"Resource\": \"*\"\n            }\n        ]\n    }\n    ```\n\n    The image below visualizes what permissions are granted:\n\n    ![Limited Role Policy](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/limited_role_policy.png)\n\n7. Once the policy is created, return to the “Create Role” browser tab and refresh to see the policy we created listed. Select the policy and click “Next.”\n8. In the Tags section, we don’t need to set any Tags, except if it’s required in your organization. Let’s proceed to Review.\n9. Specify a Name for your new Role. You will see the policy we created listed under policies and click “Create Role” to complete the process.\n10. Click on the new Role you created in the list of Roles to view its details. You may have to search for it in the list of Roles if it’s not listed in the first view. Copy the Role ARN provided – we will need it on the GitLab Kubernetes Integration page.\n\n### Step 2 - Create Service Role\n\nThe Service Role is required to allow Amazon EKS and the Kubernetes control plane to manage AWS resources on your behalf.\n\n1. In the IAM Management Console, click on “Create Role” and select the “AWS service” tab.\n2. Select EKS in the list of services and Use Cases as shown below and click Next.\n\n    ![Service Role](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/service_role.png)\n\n3. You will notice the “AmazonEKSClusterPolicy” and “AmazonEKSServicePolicy” permissions are selected; these are all we need. Click through the Tags step and create if necessary, then click Next to get to the Review step. Click “Create Role” to complete the process.\n\n    ![Role Summary](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/role_summary.png)\n\n## GitLab EKS Integration\n\nThis is the easy part! As mentioned earlier, you only need to create the Provision and Service role once if you don’t already have them in your organization’s AWS setup. You can reuse the roles for other integrations or cluster creations.\n\n1. Return to the GitLab Kubernetes Integration page and provide the Role ARN of the Provision Role we created earlier and click “Authenticate with AWS.”\n\n    ![Gitlab EKS Integration Page](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/gitlab_eks_integration_page.png)\n\n2. Once authenticated, you’ll have a page to set the parameters needed to set up your cluster as shown in the image below and click on “Create Kubernetes Cluster” to let GitLab do its magic!\n\n    The parameters you’ll need to provide are:\n    * **Kubernetes cluster name** - The name you wish to give the cluster.\n    * **Environment scope** - The [GitLab environment](https://docs.gitlab.com/ee/user/project/clusters/index.html#setting-the-environment-scope) associated with this cluster; `*` denotes the cluster will be used for deployments to all environments.\n    * **Kubernetes version** - The Kubernetes version to use. Currently, the only version supported is 1.14.\n    * **Role name** - The service role we created earlier.\n    * **Region** - The [AWS region](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html) in which the cluster will be created.\n    * **Key pair name** - Select the [key pair](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html) that you can use to connect to your worker nodes if required.\n    * **VPC** - Select a [VPC](https://docs.aws.amazon.com/vpc/latest/userguide/what-is-amazon-vpc.html) to use for your EKS Cluster resources.\n    * **Subnets** - Choose the [subnets](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Subnets.html) in your VPC where your worker nodes will run.\n    * **Security group** - Choose the [security group](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_SecurityGroups.html) to apply to the EKS-managed Elastic Network Interfaces that are created in your worker node subnets. AWS provides a default group, which can be used for the purpose of this guide. However, you are advised to setup up the right rules required for your resources.\n    * **Instance type** - The AWS [instance type](https://aws.amazon.com/ec2/instance-types/) of your worker nodes.\n    * **Node count** - The number of worker nodes.\n    * **GitLab-managed cluster** - Leave this checked if you want [GitLab to manage namespaces and service accounts](https://docs.gitlab.com/ee/user/project/clusters/index.html#gitlab-managed-clusters) for this cluster.\n\n    ![Gitlab EKS Integration Page](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/gitlab_eks_integration_post_auth.png)\n\n3. The cluster creation process will take approximately 10 minutes. Once done you can proceed to install some predefined applications. At the very least, you need to install the following:\n    - **Helm Tiller**: This is required to install the other applications.\n    - **Ingress**: This provides SSL termination, load balancing and name-based virtual hosting you your applications. It acts as a web proxy for your application, which is useful when using AutoDevOps or deploying your own apps.\n    - **Cert Manager**: This is a native Kubernetes certificate management controller, which helps in issuing certificates using Let’s Encrypt. You don’t need this if you want to use a custom Certificate issuer.\n    - **Prometheus**: GitLab uses the Prometheus integration for automatic monitoring of your applications to collect metrics from Kubernetes containers allowing you to understand what is going on from within the GitLab UI.\n\n    ![Gitlab EKS Integration Page](https://about.gitlab.com/images/blogimages/gitlab-eks-integration/gitlab_eks_integration_post_cluster.png)\n\n4. To make use of Auto Review Apps and Auto Deploy stages of [AutoDevOps](https://docs.gitlab.com/ee/topics/autodevops/quick_start_guide.html), you will need to specify a Base Domain name with a wild card DNS pointing to the Ingress Endpoint generated when you Install Ingress in the list of predefined apps.\n\n## Summary\n\nIn this tutorial, we looked at how GitLab integrates with Amazon EKS, allowing Kubernetes clusters to be created easily from the GitLab UI after setting the right permissions. As we’ve seen, developer productivity is greatly improved by no longer having to manually set up clusters. Also, the same cluster can be used for multiple projects when Amazon EKS is integrated with GitLab at the Group and Instance levels, thus making onboarding new projects a breeze. After integration, the possibilities of what developers can achieve is enormous.\n\nIn the next part of this tutorial, we will look at how to deploy your applications on an Amazon EKS cluster using AutoDevOps.\n",[23,24,25],"kubernetes","features","demo","yml",{},true,"/en-us/blog/gitlab-eks-integration-how-to",{"title":15,"description":16,"ogTitle":15,"ogDescription":16,"noIndex":12,"ogImage":19,"ogUrl":31,"ogSiteName":32,"ogType":33,"canonicalUrls":31},"https://about.gitlab.com/blog/gitlab-eks-integration-how-to","https://about.gitlab.com","article","en-us/blog/gitlab-eks-integration-how-to",[23,24,25],"u8gOJw9NJP6usLaBazn96skHXR2MefbH7_On5csRtpA",{"data":38},{"logo":39,"freeTrial":44,"sales":49,"login":54,"items":59,"search":367,"minimal":398,"duo":417,"pricingDeployment":427},{"config":40},{"href":41,"dataGaName":42,"dataGaLocation":43},"/","gitlab

Rizzi","https://res.cloudinary.com/about-gitlab-com/image/upload/v1772111172/mwhgbjawn62kymfwrhle.png","2026-03-12","If you're a platform engineer, you've probably had this conversation:\n  \n*\"Security says we need to use hardened base images.\"*\n\n*\"Great, where do I configure credentials for yet another registry?\"*\n\n*\"Also, how do we make sure everyone actually uses them?\"*\n\nOr this one:\n\n*\"Why are our builds so slow?\"*\n\n*\"We're pulling the same 500MB image from Docker Hub in every single job.\"*\n\n*\"Can't we just cache these somewhere?\"*\n\nI've been working on [Container Virtual Registry](https://docs.gitlab.com/user/packages/virtual_registry/container/) at GitLab specifically to solve these problems. It's a pull-through cache that sits in front of your upstream registries — Docker Hub, dhi.io (Docker Hardened Images), MCR, and Quay — and gives your teams a single endpoint to pull from. Images get cached on the first pull. Subsequent pulls come from the cache. Your developers don't need to know or care which upstream a particular image came from.\n\nThis article shows you how to set up Container Virtual Registry, specifically with Docker Hardened Images in mind, since that's a combination that makes a lot of sense for teams concerned about security and not making their developers' lives harder.\n\n## What problem are we actually solving?\n\nThe Platform teams I usually talk to manage container images across three to five registries:\n\n* **Docker Hub** for most base images\n* **dhi.io** for Docker Hardened Images (security-conscious workloads)\n* **MCR** for .NET and Azure tooling\n* **Quay.io** for Red Hat ecosystem stuff\n* **Internal registries** for proprietary images\n\nEach one has its own:\n\n* Authentication mechanism\n* Network latency characteristics\n* Way of organizing image paths\n\nYour CI/CD configs end up littered with registry-specific logic. Credential management becomes a project unto itself. And every pipeline job pulls the same base images over the network, even though they haven't changed in weeks.\n\nContainer Virtual Registry consolidates this. One registry URL. One authentication flow (GitLab's). Cached images are served from GitLab's infrastructure rather than traversing the internet each time.\n\n## How it works\n\nThe model is straightforward:\n\n```text\nYour pipeline pulls:\n  gitlab.com/virtual_registries/container/1000016/python:3.13\n\nVirtual registry checks:\n  1. Do I have this cached? → Return it\n  2. No? → Fetch from upstream, cache it, return it\n\n```\n\nYou configure upstreams in priority order. When a pull request comes in, the virtual registry checks each upstream until it finds the image. The result gets cached for a configurable period (default 24 hours).\n\n```text\n┌─────────────────────────────────────────────────────────┐\n│                    CI/CD Pipeline                       │\n│                          │                              │\n│                          ▼                              │\n│   gitlab.com/virtual_registries/container/\u003Cid>/image   │\n└─────────────────────────────────────────────────────────┘\n                           │\n                           ▼\n┌─────────────────────────────────────────────────────────┐\n│            Container Virtual Registry                   │\n│                                                         │\n│  Upstream 1: Docker Hub ────────────────┐               │\n│  Upstream 2: dhi.io (Hardened) ────────┐│               │\n│  Upstream 3: MCR ─────────────────────┐││               │\n│  Upstream 4: Quay.io ────────────────┐│││               │\n│                                      ││││               │\n│                    ┌─────────────────┴┴┴┴──┐            │\n│                    │        Cache          │            │\n│                    │  (manifests + layers) │            │\n│                    └───────────────────────┘            │\n└─────────────────────────────────────────────────────────┘\n```\n\n## Why this matters for Docker Hardened Images\n\n[Docker Hardened Images](https://docs.docker.com/dhi/) are great because of the minimal attack surface, near-zero CVEs, proper software bills of materials (SBOMs), and SLSA provenance. If you're evaluating base images for security-sensitive workloads, they should be on your list.\n\nBut adopting them creates the same operational friction as any new registry:\n\n* **Credential distribution**: You need to get Docker credentials to every system that pulls images from dhi.io.\n* **CI/CD changes**: Every pipeline needs to be updated to authenticate with dhi.io.\n* **Developer friction**: People need to remember to use the hardened variants.\n* **Visibility gap**: It's difficulat to tell if teams are actually using hardened images vs. regular ones.\n\nVirtual registry addresses each of these:\n\n**Single credential**: Teams authenticate to GitLab. The virtual registry handles upstream authentication. You configure Docker credentials once, at the registry level, and they apply to all pulls.\n\n**No CI/CD changes per-team**: Point pipelines at your virtual registry. Done. The upstream configuration is centralized.\n\n**Gradual adoption**: Since images get cached with their full path, you can see in the cache what's being pulled. If someone's pulling `library/python:3.11` instead of the hardened variant, you'll know.\n\n**Audit trail**: The cache shows you exactly which images are in active use. Useful for compliance, useful for understanding what your fleet actually depends on.\n\n## Setting it up\n\nHere's a real setup using the Python client from this demo project.\n\n### Create the virtual registry\n\n```python\nfrom virtual_registry_client import VirtualRegistryClient\n\nclient = VirtualRegistryClient()\n\nregistry = client.create_virtual_registry(\n    group_id=\"785414\",  # Your top-level group ID\n    name=\"platform-images\",\n    description=\"Cached container images for platform teams\"\n)\n\nprint(f\"Registry ID: {registry['id']}\")\n# You'll need this ID for the pull URL\n```\n\n### Add Docker Hub as an upstream\n\nFor official images like Alpine, Python, etc.:\n\n```python\ndocker_upstream = client.create_upstream(\n    registry_id=registry['id'],\n    url=\"https://registry-1.docker.io\",\n    name=\"Docker Hub\",\n    cache_validity_hours=24\n)\n```\n\n### Add Docker Hardened Images (dhi.io)\n\nDocker Hardened Images are hosted on `dhi.io`, a separate registry that requires authentication:\n\n```python\ndhi_upstream = client.create_upstream(\n    registry_id=registry['id'],\n    url=\"https://dhi.io\",\n    name=\"Docker Hardened Images\",\n    username=\"your-docker-username\",\n    password=\"your-docker-access-token\",\n    cache_validity_hours=24\n)\n```\n\n### Add other upstreams\n\n```python\n# MCR for .NET teams\nclient.create_upstream(\n    registry_id=registry['id'],\n    url=\"https://mcr.microsoft.com\",\n    name=\"Microsoft Container Registry\",\n    cache_validity_hours=48\n)\n\n# Quay for Red Hat stuff\nclient.create_upstream(\n    registry_id=registry['id'],\n    url=\"https://quay.io\",\n    name=\"Quay.io\",\n    cache_validity_hours=24\n)\n```\n\n### Update your CI/CD\n\nHere's a `.gitlab-ci.yml` that pulls through the virtual registry:\n\n```yaml\nvariables:\n  VIRTUAL_REGISTRY_ID: \u003Cyour_virtual_registry_ID>\n\n  \nbuild:\n  image: docker:24\n  services:\n    - docker:24-dind\n  before_script:\n    # Authenticate to GitLab (which handles upstream auth for you)\n    - echo \"${CI_JOB_TOKEN}\" | docker login -u gitlab-ci-token --password-stdin gitlab.com\n  script:\n    # All of these go through your single virtual registry\n    \n    # Official Docker Hub images (use library/ prefix)\n    - docker pull gitlab.com/virtual_registries/container/${VIRTUAL_REGISTRY_ID}/library/alpine:latest\n    \n    # Docker Hardened Images from dhi.io (no prefix needed)\n    - docker pull gitlab.com/virtual_registries/container/${VIRTUAL_REGISTRY_ID}/python:3.13\n    \n    # .NET from MCR\n    - docker pull gitlab.com/virtual_registries/container/${VIRTUAL_REGISTRY_ID}/dotnet/sdk:8.0\n```\n\n### Image path formats\n\nDifferent registries use different path conventions:\n\n| Registry | Pull URL Example |\n|----------|------------------|\n| Docker Hub (official) | `.../library/python:3.11-slim` |\n| Docker Hardened Images (dhi.io) | `.../python:3.13` |\n| MCR | `.../dotnet/sdk:8.0` |\n| Quay.io | `.../prometheus/prometheus:latest` |\n\n### Verify it's working\n\nAfter some pulls, check your cache:\n\n```python\nupstreams = client.list_registry_upstreams(registry['id'])\nfor upstream in upstreams:\n    entries = client.list_cache_entries(upstream['id'])\n    print(f\"{upstream['name']}: {len(entries)} cached entries\")\n\n```\n\n## What the numbers look like\n\nI ran tests pulling images through the virtual registry:\n\n| Metric | Without Cache | With Warm Cache |\n|--------|---------------|-----------------|\n| Pull time (Alpine) | 10.3s | 4.2s |\n| Pull time (Python 3.13 DHI) | 11.6s | ~4s |\n| Network roundtrips to upstream | Every pull | Cache misses only |\n\n\n\n\nThe first pull is the same speed (it has to fetch from upstream). Every pull after that, for the cache validity period, comes straight from GitLab's storage. No network hop to Docker Hub, dhi.io, MCR, or wherever the image lives.\n\nFor a team running hundreds of pipeline jobs per day, that's hours of cumulative build time saved.\n\n## Practical considerations\nHere are some considerations to keep in mind:\n\n### Cache validity\n\n24 hours is the default. For security-sensitive images where you want patches quickly, consider 12 hours or less:\n\n```python\nclient.create_upstream(\n    registry_id=registry['id'],\n    url=\"https://dhi.io\",\n    name=\"Docker Hardened Images\",\n    username=\"your-username\",\n    password=\"your-token\",\n    cache_validity_hours=12\n)\n```\n\nFor stable, infrequently-updated images (like specific version tags), longer validity is fine.\n\n### Upstream priority\n\nUpstreams are checked in order. If you have images with the same name on different registries, the first matching upstream wins.\n\n### Limits\n\n* Maximum of 20 virtual registries per group\n* Maximum of 20 upstreams per virtual registry\n\n## Configuration via UI\n\nYou can also configure virtual registries and upstreams directly from the GitLab UI—no API calls required. Navigate to your group's **Settings > Packages and registries > Virtual Registry** to:\n\n* Create and manage virtual registries\n* Add, edit, and reorder upstream registries\n* View and manage the cache\n* Monitor which images are being pulled\n\n## What's next\n\nWe're actively developing:\n\n* **Allow/deny lists**: Use regex to control which images can be pulled from specific upstreams.\n\nThis is beta software. It works, people are using it in production, but we're still iterating based on feedback.\n\n## Share your feedback\n\nIf you're a platform engineer dealing with container registry sprawl, I'd like to understand your setup:\n\n* How many upstream registries are you managing?\n* What's your biggest pain point with the current state?\n* Would something like this help, and if not, what's missing?\n\nPlease share your experiences in the [Container Virtual Registry feedback issue](https://gitlab.com/gitlab-org/gitlab/-/work_items/589630).\n## Related resources\n- [New GitLab metrics and registry features help reduce CI/CD bottlenecks](https://about.gitlab.com/blog/new-gitlab-metrics-and-registry-features-help-reduce-ci-cd-bottlenecks/#container-virtual-registry)\n- [Container Virtual Registry documentation](https://docs.gitlab.com/user/packages/virtual_registry/container/)\n- [Container Virtual Registry API](https://docs.gitlab.com/api/container_virtual_registries/)",[714,715,24],"tutorial","product",{"featured":12,"template":13,"slug":717},"using-gitlab-container-virtual-registry-with-docker-hardened-images",{"content":719,"config":729},{"title":720,"description":721,"authors":722,"heroImage":724,"date":725,"category":9,"tags":726,"body":728},"How IIT Bombay students are coding the future with GitLab","At GitLab, we often talk about how software accelerates innovation.

The energy was electric, the coffee was flowing, and the talent was undeniable. But what struck us most wasn't just the code — it was the sheer determination of students to solve real-world problems, often overcoming significant logistical and financial hurdles to simply be in the room.\n\n\nThrough our [GitLab for Education program](https://about.gitlab.com/solutions/education/), we aim to empower the next generation of developers with tools and opportunity. Here is a look at what the students built, and how they used GitLab to bridge the gap between idea and reality.\n\n## The challenge: Build faster, build securely\n\nThe premise for the GitLab track of the hackathon was simple: Don't just show us a product; show us how you built it. We wanted to see how students utilized GitLab's platform — from Issue Boards to CI/CD pipelines — to accelerate the development lifecycle.\n\nThe results were inspiring.\n\n## The winners\n\n### 1st place: Team Decode — Democratizing Scientific Research\n\n**Project:** FIRE (Fast Integrated Research Environment)\n\nTeam Decode took home the top prize with a solution that warms a developer's heart: a local-first, blazing-fast data processing tool built with [Rust](https://about.gitlab.com/blog/secure-rust-development-with-gitlab/) and Tauri. They identified a massive pain point for data science students: existing tools are fragmented, slow, and expensive.\n\nTheir solution, FIRE, allows researchers to visualize complex formats (like NetCDF) instantly. What impressed the judges most was their \"hacker\" ethos. They didn't just build a tool; they built it to be open and accessible.\n\n**How they used GitLab:** Since the team lived far apart, asynchronous communication was key. They utilized **GitLab Issue Boards** and **Milestones** to track progress and integrated their repo with Telegram to get real-time push notifications. As one team member noted, \"Coordinating all these technologies was really difficult, and what helped us was GitLab... the Issue Board really helped us track who was doing what.\"\n\n![Team Decode](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380253/epqazj1jc5c7zkgqun9h.jpg)\n\n### 2nd place: Team BichdeHueDost — Reuniting to Solve Payments\n\n**Project:** SemiPay (RFID Cashless Payment for Schools)\n\nThe team name, BichdeHueDost, translates to \"Friends who have been set apart.\" It's a fitting name for a group of friends who went to different colleges but reunited to build this project. They tackled a unique problem: handling cash in schools for young children. Their solution used RFID cards backed by a blockchain ledger to ensure secure, cashless transactions for students.\n\n**How they used GitLab:** They utilized [GitLab CI/CD](https://about.gitlab.com/topics/ci-cd/) to automate the build process for their Flutter application (APK), ensuring that every commit resulted in a testable artifact. This allowed them to iterate quickly despite the \"flaky\" nature of cross-platform mobile development.\n\n![Team BichdeHueDost](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380253/pkukrjgx2miukb6nrj5g.jpg)\n\n### 3rd place: Team ZenYukti — Agentic Repository Intelligence\n\n**Project:** RepoInsight AI (AI-powered, GitLab-native intelligence platform)\n\nTeam ZenYukti impressed us with a solution that tackles a universal developer pain point: understanding unfamiliar codebases. What stood out to the judges was the tool's practical approach to onboarding and code comprehension: RepoInsight-AI automatically generates documentation, visualizes repository structure, and even helps identify bugs, all while maintaining context about the entire codebase.\n\n**How they used GitLab:** The team built a comprehensive CI/CD pipeline that showcased GitLab's security and DevOps capabilities. They integrated [GitLab's Security Templates](https://gitlab.com/gitlab-org/gitlab/-/tree/master/lib/gitlab/ci/templates/Security) (SAST, Dependency Scanning, and Secret Detection), and utilized [GitLab Container Registry](https://docs.gitlab.com/user/packages/container_registry/) to manage their Docker images for backend and frontend components. They created an AI auto-review bot that runs on merge requests, demonstrating an \"agentic workflow\" where AI assists in the development process itself.\n\n![Team ZenYukti](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380253/ymlzqoruv5al1secatba.jpg)\n\n## Beyond the code: A lesson in inclusion\n\nWhile the code was impressive, the most powerful moment of the event happened away from the keyboard.\n\nDuring the feedback session, we learned about the journey Team ZenYukti took to get to Mumbai. They traveled over 24 hours, covering nearly 1,800 kilometers. Because flights were too expensive and trains were booked, they traveled in the \"General Coach,\" a non-reserved, severely overcrowded carriage.\n\nAs one student described it:\n\n*\"You cannot even imagine something like this... there are no seats... people sit on the top of the train. This is what we have endured.\"*\n\nThis hit home. [Diversity, Inclusion, and Belonging](https://handbook.gitlab.com/handbook/company/culture/inclusion/) are core values at GitLab. We realized that for these students, the barrier to entry wasn't intellect or skill, it was access.\n\nIn that moment, we decided to break that barrier. We committed to reimbursing the travel expenses for the participants who struggled to get there. It's a small step, but it underlines a massive truth: **talent is distributed equally, but opportunity is not.**\n\n![hackathon class together](https://res.cloudinary.com/about-gitlab-com/image/upload/v1767380252/o5aqmboquz8ehusxvgom.jpg)\n\n### The future is bright (and automated)\n\nWe also saw incredible potential in teams like Prometheus, who attempted to build an autonomous patch remediation tool (DevGuardian), and Team Arrakis, who built a voice-first job portal for blue-collar workers using [GitLab Duo](https://about.gitlab.com/gitlab-duo/) to troubleshoot their pipelines.\n\nTo all the students who participated: You are the future. Through [GitLab for Education](https://about.gitlab.com/solutions/education/), we are committed to providing you with the top-tier tools (like GitLab Ultimate) you need to learn, collaborate, and change the world — whether you are coding from a dorm room, a lab, or a train carriage. **Keep shipping.**\n\n> :bulb: Learn more about the [GitLab for Education program](https://about.gitlab.com/solutions/education/).\n",{"slug":730,"featured":12,"template":13},"how-iit-bombay-students-code-future-with-gitlab",{"content":732,"config":740},{"title":733,"description":734,"authors":735,"heroImage":736,"date":737,"category":9,"tags":738,"body":739},"Artois University elevates research and curriculum with GitLab Ultimate for Education","Artois University's CRIL leveraged the GitLab for Education program to gain free access to Ultimate, transforming advanced research and computer science curricula.",[723],"https://res.cloudinary.com/about-gitlab-com/image/upload/v1750099203/Blog/Hero%20Images/Blog/Hero%20Images/blog-image-template-1800x945%20%2820%29_2bJGC5ZP3WheoqzlLT05C5_1750099203484.png","2025-12-10",[611,259,715],"Leading academic institutions face a critical challenge: how to provide thousands of students and researchers with industry-standard, **full-featured DevSecOps tools** without compromising institutional control. Many start with basic version control, but the modern curriculum demands integrated capabilities for planning, security, and advanced CI/CD.\n\nThe **GitLab for Education program** is designed to solve this by providing access to **GitLab Ultimate** for qualifying institutions, allowing them to scale their operations and elevate their academic offerings. \n\nThis article showcases a powerful success story from the **Centre de Recherche en Informatique de Lens (CRIL)**, a joint laboratory of **Artois University** and CNRS in France. After years of relying solely on GitLab Community Edition (CE), the university's move to GitLab Ultimate through the GitLab for Education program immediately unlocked advanced capabilities, transforming their teaching, research, and contribution workflows virtually overnight. This story demonstrates why GitLab Ultimate is essential for institutions seeking to deliver advanced computer science and research curricula.\n\n## GitLab Ultimate unlocked: Managing scale and driving academic value\n\n**Artois University's** self-managed GitLab instance is a large-scale operation, supporting nearly **3,000 users** across approximately **19,000 projects**, primarily serving computer science students and researchers. While GitLab Community Edition was robust, the upgrade to GitLab Ultimate provided the sophisticated tooling necessary for managing this scale and facilitating advanced university-level work.\n\n***\"We can see the difference,\" says Daniel Le Berre, head of research at CRIL and the instance maintainer. \"It's a completely different product. Each week reveals new features that directly enhance our productivity and teaching.\"***\n\nThe institution joined the GitLab for Education program specifically because it covers both **instructional and non-commercial research use cases** and offers full access to Ultimate's features, removing significant cost barriers.\n\n### Key GitLab Ultimate benefits for students and researchers\n\n* **Advanced project management at scale:** Master's students now benefit from **GitLab Ultimate's project planning features**. This enables them to structure, track, and manage complex, long-term research projects using professional methodologies like portfolio management and advanced issue tracking that seamlessly roll up across their thousands of projects.\n\n* **Enhanced visibility:** Features like improved dashboards and code previews directly in Markdown files dramatically streamline tracking and documentation review, reducing administrative friction for both instructors and students managing large project loads.\n\n## Comprehensive curriculum: From concepts to continuous delivery\n\nGitLab Ultimate is deeply integrated into the computer science curriculum, moving students beyond simple `git` commands to practical **DevSecOps implementation**.\n\n* **Git fundamentals:** Students begin by visualizing concepts using open-source tools to master Git concepts.\n\n* **Full CI/CD implementation:** Students use GitLab CI for rigorous **Test-Driven Development (TDD)** in their software projects. They learn to build, test, and perform quality assurance using unit and integration testing pipelines—core competency made seamless by the integrated platform.\n\n* **DevSecOps for research and documentation:** The university teaches students that DevSecOps principles are vital for all collaborative work. Inspired by earlier work in Delft, students manage and produce critical research documentation (PDFs from Markdown files) using GitLab, incorporating quality checks like linters and spell checks directly in the CI pipeline. This ensures high-quality, reproducible research output.\n\n* **Future-proofing security skills:** The GitLab Ultimate platform immediately positions the institution to incorporate advanced DevSecOps features like SAST and DAST scanning as their research and development code projects grow, ensuring students are prepared for industry security standards.\n\n## Accelerating open source contributions with GitLab Duo\n\nAccess to the full GitLab platform, including our AI capabilities, has empowered students to make impactful contributions to the wider open source community faster than ever before.\n\nTwo Master's students recently completed direct contributions to the GitLab product, adding the **ORCID identifier** into user profiles. Working on GitLab.com, they leveraged **GitLab Duo's AI chat and code suggestions** to navigate the codebase efficiently.\n\n***\"This would not have been possible without GitLab Duo,\" Daniel Le Berre notes. \"The AI features helped students, who might have lacked deep codebase knowledge, deliver meaningful contributions in just two weeks.\"***\n\nThis demonstrates how providing students with cutting-edge tools **accelerates their learning and impact**, allowing them to translate classroom knowledge into real-world contributions immediately.\n\n## Empowering open research and institutional control\n\nThe stability of the self-managed instance at Artois University is key to its success. This model guarantees **institutional control and stability** — a critical factor for long-term research preservation.\n\nThe institution's expertise in this area was recently highlighted in a major 2024 study led by CRIL, titled: \"[Higher Education and Research Forges in France - Definition, uses, limitations encountered and needs analysis](https://hal.science/hal-04208924v4)\" ([Project on GitLab](https://gitlab.in2p3.fr/coso-college-codes-sources-et-logiciels/forges-esr-en)). The research found that the vast majority of public forges in French Higher Education and Research relied on **GitLab**. This finding underscores the consensus among academic leaders that self-hosted solutions are essential for **data control and longevity**, especially when compared to relying on external, commercial forges.\n\n## Unlock GitLab Ultimate for your institution today\n\nThe success story of **Artois University's CRIL** proves the transformative power of the GitLab for Education program.
