Customers request more features and the application needs to scale well\nto meet user demands. As software grows in size, so does its complexity, to the point where we might decide that it's\ntime to split the project up into smaller, cohesive components.\n\nAs we proceed to tackle this complexity we want to ensure that our CI/CD pipelines continue to validate\nthat all the pieces work correctly together.\n\nThere are two typical paths to splitting up software projects:\n\n- **Isolating independent modules within the same repository**: For example, separating the UI from the backend,\n  the documentation from code, or extracting code into independent packages.\n- **Extracting code into a separate repository**: For example, extracting some generic logic into a library, or creating\n  independent microservices.\n\nWhen we pick a path for splitting up the project, we should also adapt the CI/CD pipeline to match.\n\nFor the first path, [GitLab CI/CD](/topics/ci-cd/) provides [parent-child pipelines](https://docs.gitlab.com/ee/ci/pipelines/downstream_pipelines.html) as a feature that helps manage complexity while keeping it all in a monorepo.\n\nFor the second path, [multi-project pipelines](https://docs.gitlab.com/ee/ci/pipelines/downstream_pipelines.html)\nare the glue that helps ensure multiple separate repositories work together.\n\nLet's look into how these two approaches differ, and understand how to best leverage them.\n\n## Parent-child pipelines\n\nIt can be challenging to maintain complex CI/CD pipeline configurations, especially when you need to coordinate many jobs that may relate\nto different components, while at the same time keeping the pipeline efficient.\n\nLet's imagine we have an app with all code in the same repository, but split into UI and backend components. A \"one-size-fits-all\" pipeline for this app probably would have all the jobs grouped into common stages that cover all the components. The default is to use `build`, `test`, and `deploy` stages.\nUnfortunately, this could be a source of inefficiency because the UI and backend represent two separate tracks of the pipeline.\nThey each have their own independent requirements and structure and likely don't depend on each other.\nThe UI might not need the `build` stage at all, but it might instead need a `system-test` stage with jobs that test the app end-to-end.\nSimilarly, the UI jobs from `system-test` might not need to wait for backend jobs to complete.\n\n[Parent-child pipelines](https://docs.gitlab.com/ee/ci/pipelines/downstream_pipelines.html) help here,\nenabling you to extract cohesive parts of the pipeline into child pipelines that runs in isolation.\n\nWith parent-child pipelines we could break the configurations down into two separate\ntracks by having two separate jobs trigger child pipelines:\n\n- The `ui` job triggers a child pipeline that runs all the UI jobs.\n- The `backend` job triggers a separate child pipeline that runs all the backend jobs.\n\n```yaml\nui:\n  trigger:\n    include: ui/.gitlab-ci.yml\n    strategy: depend\n  rules:\n    - changes: [ui/*]\nbackend:\n  trigger:\n    include: backend/.gitlab-ci.yml\n    strategy: depend\n  rules:\n    - changes: [backend/*]\n\n```\n\nThe modifier `strategy: depend`, which is also available for multi-project pipelines, makes the trigger job reflect the status of the\ndownstream (child) pipeline and waits for it to complete. Without `strategy: depend` the trigger job succeeds immediately after creating the downstream pipeline.\n\nNow the frontend and backend teams can manage their CI/CD configurations without impacting each other's pipelines. In addition to that, we can now explicitly visualize the two workflows.\n\n![example parent-child pipeline](https://about.gitlab.com/images/blogimages/2022-02-01-parent-child-vs-multi-project-pipelines/parent-child.png){: .shadow.medium.center}\n\nThe two pipelines run in isolation, so we can set variables or configuration in one without affecting the other. For example, we could use `rules:changes` or `workflow:rules` inside `backend/.gitlab-ci.yml`, but use something completely different in `ui/.gitlab-ci.yml`.\n\nChild pipelines run in the same context of the parent pipeline, which is the combination of project, Git ref and commit SHA. Additionally, the child pipeline inherits some information from the parent pipeline, including Git push data like `before_sha`, `target_sha`, the related merge request, etc.\nHaving the same context ensures that the child pipeline can safely run as a sub-pipeline of the parent, but be in complete isolation.\n\nA programming analogy to parent-child pipelines would be to break down long procedural code into smaller, single-purpose functions.\n\n## Multi-project pipelines\n\nIf our app spans across different repositories, we should instead leverage [multi-project pipelines](https://docs.gitlab.com/ee/ci/pipelines/downstream_pipelines.html). Each repository defines a pipeline that suits the project's needs. Then, these standalone and independent pipelines can be chained together to create essentially a much bigger pipeline that ensures all the projects are integrated correctly.\n\nThere can be endless possibilities and topologies, but let's explore a simple case of asking another project\nto run a service for our pipeline.\n\nThe app is divided into multiple repositories, each hosting an independent component of the app.\nWhen one of the components changes, that project's pipeline runs.\nIf the earlier jobs in the pipeline are successful, a final job triggers a pipeline on a different project, which is the project responsible for building, running smoke tests, and\ndeploying the whole app. If the component pipeline fails because of a bug, the process is interrupted and there is no\nneed to trigger a pipeline for the main app project.\n\nThe component project's pipeline:\n\n```yaml\nbuild:\n  stage: build\n  script: ./build_component.sh\n\ntest:\n  stage: test\n  script: ./test_component.sh\n\ndeploy:\n  stage: deploy\n  trigger:\n    project: myorg/app\n    strategy: depend\n\n```\n\nThe full app project's pipeline in `myorg/app` project:\n\n```yaml\nbuild:\n  stage: build\n  script: ./build_app.sh  # build all components\n\nqa-test:\n  stage: test\n  script: ./qa_test.sh\n\nsmoke-test:\n  stage: test\n  script: ./smoke_test.sh\n\ndeploy:\n  stage: deploy\n  script: ./deploy_app.sh\n\n```\n\n![example multi-project pipeline](https://about.gitlab.com/images/blogimages/2022-02-01-parent-child-vs-multi-project-pipelines/multi-project.png){: .shadow.center}\n\nIn our example, the component pipeline (upstream) triggers a downstream multi-project pipeline to perform a service:\nverify the components work together, then deploy the whole app.\n\nA programming analogy to multi-project pipelines would be like calling an external component or function to\neither receive a service (using `strategy:depend`) or to notify it that an event occurred (without `strategy:depend`).\n\n## Key differences between parent-child and multi-project pipelines\n\nAs seen above, the most obvious difference between parent-child and multi-project pipelines is the project\nwhere the pipelines run, but there are are other differences to be aware of.\n\nContext:\n\n- Parent-child pipelines run on the same context: same project, ref, and commit SHA.\n- Multi-project pipelines run on completely separate contexts. The upstream multi-project pipeline can indicate [a ref to use](https://docs.gitlab.com/ee/ci/pipelines/downstream_pipelines.html), which can indicate what version of the pipeline to trigger.\n\nControl:\n\n- A parent pipeline _generates_ a child pipeline, and the parent can have a high degree of control over what the child pipeline\n  runs. The parent can even [dynamically generate configurations for child pipelines](https://docs.gitlab.com/ee/ci/pipelines/downstream_pipelines.html).\n- An upstream pipeline _triggers_ a downstream multi-project pipeline. The upstream (triggering) pipeline does not have much control over the structure of the downstream (triggered) pipeline.\n  The upstream project treats the downstream pipeline as a black box.\n  It can only choose the ref to use and pass some variables downstream.\n\nSide-effects:\n\n- The final status of a parent pipeline, like other normal pipelines, affects the status of the ref the pipeline runs against. For example, if a parent pipeline fails on the `main` branch, we say that `main` is broken.\n  The status of a ref is used in various scenarios, including [downloading artifacts](https://docs.gitlab.com/ee/api/job_artifacts.html#download-the-artifacts-archive) from the latest successful pipeline.\n\n  Child pipelines, on the other hand, run on behalf of the parent pipeline, and they don't directly affect the ref status. If triggered using `strategy: depend`, a child pipeline affects the status of the parent pipeline.\n  In turn, the parent pipeline can be configured to fail or succeed based on `allow_failure:` configuration on the job triggering the child pipeline.\n- A multi-project downstream pipeline may affect the status of the upstream pipeline if triggered using `strategy: depend`,\n  but each downstream pipeline affects the status of the ref in the project they run.\n- Parent and child pipelines that are still running are all automatically canceled if interruptible when a new pipeline is created for the same ref.\n- Multi-project downstream pipelines are not automatically canceled when a new upstream pipeline runs for the same ref. The auto-cancelation feature only works within the same project.\n  Downstream multi-project pipelines are considered \"external logic\". They can only be auto-canceled when configured to be interruptible\n  and a new pipeline is triggered for the same ref on the downstream project (not the upstream project).\n\nVisibility:\n\n- Child pipelines are not directly visible in the pipelines index page because they are considered internal\n  sub-components of the parent pipeline. This is to enforce the fact that child pipelines are not standalone and they are considered sub-components of the parent pipeline.\n  Child pipelines are discoverable only through their parent pipeline page.\n- Multi-project pipelines are standalone pipelines because they are normal pipelines, but just happen to be triggered by an another project's pipeline. They are all visible in the pipeline index page.\n\n## Conclusions\n\nParent-child pipelines inherit a lot of the design from multi-project pipelines, but parent-child pipelines have differences that make them a very unique type\nof pipeline relationship.\n\nSome of the parent-child pipelines work we at GitLab will be focusing on is about surfacing job reports generated in child pipelines as merge request widgets,\ncascading cancelation and removal of pipelines as well as passing variables across related pipelines.\nSome of the parent-child pipeline work we at GitLab plan to focus on relates to:\n\n- Surfacing job reports generated in child pipelines in merge request widgets.\n- Cascading cancelation down to child pipelines.\n- Cascading removal down to child pipelines.\n- Passing variables across related pipelines.\n\nYou can check [this issue](https://gitlab.com/gitlab-org/gitlab/-/issues/336884) for planned future developments on parent-child and multi-project pipelines.\nLeave feedback or let us know how we can help.\n\nCover image by [Ravi Roshan](https://unsplash.com/@ravi_roshan_inc?utm_source=unsplash&utm_medium=referral&utm_content=creditCopyText) on

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/)",[717,718,25],"tutorial","product",{"featured":12,"template":13,"slug":720},"using-gitlab-container-virtual-registry-with-docker-hardened-images",{"content":722,"config":732},{"title":723,"description":724,"authors":725,"heroImage":727,"date":728,"category":9,"tags":729,"body":731},"How IIT Bombay students are coding the future with GitLab","At GitLab, we often talk about how software accelerates innovation.

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":733,"featured":12,"template":13},"how-iit-bombay-students-code-future-with-gitlab",{"content":735,"config":743},{"title":736,"description":737,"authors":738,"heroImage":739,"date":740,"category":9,"tags":741,"body":742},"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.",[726],"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",[614,262,718],"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.
