These easy-to-follow tutorials will focus on different user problems, including provisioning, managing a base infrastructure, and deploying various third-party or custom applications on top of them. You can also view our entire [\"Ultimate guide to GitOps with GitLab\"](/blog/the-ultimate-guide-to-gitops-with-gitlab/) tutorial series._\n\nIn this article we will use our cluster connection to manage secrets within our cluster.\n\n## Prerequisites\n\nThis article assumes that you have a Kubernetes cluster connected to GitLab using the GitLab Agent for Kubernetes. If you don't have such a cluster, I recommend looking at the linked articles above so you have a similar setup from where we will start today.\n\n## A few words about secrets management\n\nThe Kubernetes `Secret` resource is a rather tricky one! By design, secrets should have limited access and should be encrypted at rest and in transit. Still, by default, Kubernetes does not encrypt secrets at rest and accessing them might not be restricted in your cluster. We will not go into detail about how to secure your cluster with respect to secrets in this article. Instead, we want to focus on getting some secrets configured in your cluster with a GitOps approach.\n\nManaging secrets with GitOps means you store those secrets within your Git repository. Of course, you should never store unencrypted secrets in a repo, and some security people are even reluctant to store encrypted secrets in Git. We will not be that worried, but you should consider if this is an acceptable risk for you. There is an alternative we'll talk about, below, if you prefer to not manage your secrets in Git.\n\nThere are a few benefits of Git-based secrets management:\n\n- you get versioning by default\n- collaboration is supported using merge requests\n- as secrets are in code, you push responsibilities towards the development team\n- the tools used are well-known to developers\n\n## Secrets management with GitLab\n\nWhen it comes to secrets, Kubernetes, and GitLab, there are at least 3 options to choose from:\n\n- create secrets automatically from environment variables in GitLab CI\n- manage secrets through HashiCorp Vault and GitLab CI\n- manage secrets in git with a GitOps approach\n\n### Create secrets automatically from environment variables in GitLab CI\n\nThe Auto Deploy template applies every [`K8S_SECRET_` prefixed environment variable](https://docs.gitlab.com/ee/topics/autodevops/customize.html#application-secret-variables) into your cluster as a Kubernetes Secret. Later, your applications can reference these secrets. This approach is the simplest to use, especially if you would like to use [Auto DevOps](/topics/devops/). We will look into it in a future article.\n\nWhile simple to use, with this approach your secrets are stored in the GitLab database, instead of `Git`. That means you lose versioning of the secrets, you need `Maintainer` rights to modify these secrets, and you lose the ability to approve a change of secret in a merge request.\n\n### Manage secrets through HashiCorp Vault and GitLab CI\n\n[GitLab CI/CD integrates with HashiCorp Vault](https://docs.gitlab.com/ee/ci/examples/authenticating-with-hashicorp-vault/#authenticating-and-reading-secrets-with-hashicorp-vault) to support advanced secrets management use cases. You can combine the `K8S_SECRET_` prefixed use case even with Vault-based secrets, and have the secrets applied automatically. \n\nWith this approach, you get the all the benefits of HashiCorp Vault, but there is a question: why do you move secrets from Vault to GitLab just to move them to your cluster instead of retrieving the secrets directly from within your cluster? We recommend leaving GitLab out of this flow if you don't have a really good reason to provide secret access to GitLab too! Vault has really great Kubernetes support, thus retrieving secrets directly should be feasible.\n\n### Manage secrets in Git with a GitOps approach\n\nTo manage secrets in Git, we will need some kind of tooling to take care of the encryption/decryption of the secrets. In this article, I will show you how to set up and use [Bitnami's Sealed Secrets](https://github.com/bitnami-labs/sealed-secrets), but you can try other tools, like [SOPS](https://github.com/mozilla/sops) too. We will look into Bitnami's approach as it targets Kubernetes exclusively, unlike SOPS that supports other use cases too, and might need a bit more setup for Kubernetes.\n\nBitnami's Sealed Secrets is composed of an in-cluster controller and a CLI tool. The cluster component defines a `SealedSecret` custom resource that stores the encrypted secret and related metadata. Once a `SealedSecret` is deployed into the cluster, the controller decrypts it and creates a native Kubernetes `Secret` resource from it. To create a `SealedSecret` resource, the `kubeseal` utility can be used. `kubeseal` can take a public key and transform and encrypt a native Kubernetes `Secret` into a `SealedSecret`, and `kubeseal` can help with retrieving the public key from the cluster-side controller too.\n\n## Setting up Bitnami's Sealed Secrets\n\nAs the GitLab Agent supports pure Kubernetes manifests to do GitOps, we will need the manifests for Sealed Secrets. Open the [Sealed Secrets releases page](https://github.com/bitnami-labs/sealed-secrets/releases/) and find the most recent release (Don't be fooled by the `helm` releases!). At the time of writing this article, the most recent [release is v0.16.0](https://github.com/bitnami-labs/sealed-secrets/releases/tag/v0.16.0). From there you can download the release `yaml`, if your cluster supports RBAC, I recommend the basic `controller.yaml` file.\n\n- Save and commit the `controller.yaml` under `kubernetes/sealed-secrets.yaml`\n\nPush the changes and wait a few seconds for them to get applied. Check that they got applied successfully using: `kubectl get pods -n kube-system -l name=sealed-secrets-controller`\n\n## Retrieving the public key\n\nWhile the user can encrypt a secret directly with `kubeseal`, this approach requires them to have access to the Kube API. Instead of providing access, we can fetch the public key from the Sealed Secrets controller and store it in the Git repo. The public key can be used to encrypt secrets, but is useless for decrypting them.\n\n```bash\nkubeseal --fetch-cert > sealed-secrets.pub.pem\n```\n\n### How to avoid storing unencrypted secrets\n\nI prefer to have an `ignored` directory within my Git repo. The content of this directory is never committed to Git, and I put every sensitive data under this directory.\n\n```bash\nmkdir ignored\ncat \u003C\u003CEOF > ignored/.gitignore\n*\n!.gitignore\nEOF\n```\n\n## Continue with setup - not needed if we use a box\n\nNow, you can create sealed secrets with the following two commands:\n\n```bash\necho \"Very secret\" | kubectl create secret generic my-secret -n gitlab-agent --dry-run=client --type=Opaque --from-file=token=/dev/stdin -o yaml > ignored/my-secret.yaml\nkubeseal --format=yaml --cert=sealed-secrets.pub.pem \u003C ignored/my-secret.yaml > kubernetes/\n```\n\nThe first command creates a regular Kubernetes `Secret` resource in the `gitlab-agent` namespace. Setting the namespace is important if you use Sealed Secrets and every SealedSecret is scoped for a specific namespace. You can read more about this in the Sealed Secrets documentation.\n\nThe second command takes a `Secret` resource object and turns it into an encrypted `SealedSecret` resource. In my case, the secret file:\n\n```yaml\napiVersion: v1\ndata:\n  token: VmVyeSBzZWNyZXQK\nkind: Secret\nmetadata:\n  creationTimestamp: null\n  name: my-secret\n  namespace: gitlab-agent\ntype: Opaque\n```\n\ngot turned into:\n\n```yaml\napiVersion: bitnami.com/v1alpha1\nkind: SealedSecret\nmetadata:\n  creationTimestamp: null\n  name: my-secret\n  namespace: gitlab-agent\nspec:\n  encryptedData:\n    token: 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\n  template:\n    metadata:\n      creationTimestamp: null\n      name: my-secret\n      namespace: gitlab-agent\n    type: Opaque\n\n```\n\nJust commit the `SealedSecret` and quickly start to watch for the event stream using `kubectl get events --all-namespaces --watch` to see when the sealed secret is unsealed and applied as a regular `Secret`.\n\n## Utility scripts\n\nIf you found the `kubeseal` command above to be quite complex, you can wrap it in a script.\n\n- Create `bin/seal-secret.sh` with the following content:\n\n```bash\n#!/bin/sh\n\nif [ $# -ne 2 ]\n  then\n    echo \"Usage: $0 ignored/my-secret.yaml output-dir/\"\n    echo \"This script requires two arguments\"\n    echo \"The first argument should be the unsealed secret\"\n    echo \"The second argument should be the directory to output the sealed secret\"\n  exit 1\nfi\n\n\nSECRET_FILE=$(basename $1)\n\nkubeseal --format=yaml --cert=sealed-secrets.pub.pem \u003C $1 > \"$2/SealedSecret.${SECRET_FILE}\"\n\necho \"Created file $2/SealedSecret.${SECRET_FILE}\"\n```\n\nThis script takes a path to a vanilla Kubernetes secret and an output directory, and tranforms your `Secret` into a `SealedSecret`.\n\n## Winding it up\n\nIn this article, we have seen how you can install Bitnami's Sealed Secret into your cluster and set it up for static secrets management. Please note the installation method provided here works for all the other 3rd party, off-the-shelf applications that can be deployed using Kubernetes manifests only.\n\n## What is next?\n\nIn the next article, we will see how you can access a Kubernetes cluster using GitLab CI/CD and why you might want to do it even if you aim for GitOps.\n\n_[Click

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.

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":731,"featured":12,"template":13},"how-iit-bombay-students-code-future-with-gitlab",{"content":733,"config":741},{"title":734,"description":735,"authors":736,"heroImage":737,"date":738,"category":9,"tags":739,"body":740},"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.",[724],"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",[611,261,715],"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.
