We've been using Vue for over a year now and life has been very good. Thanks [@lnoogn](https://twitter.com/lnoogn) for reminding me to write this article!\n\n\u003C!-- more -->\n\nOur situation reminds me of a quote about Scala from [\"Is Scala slowly dying?\"](https://www.reddit.com/r/scala/comments/2hw0bp/is_scala_slowly_dying/) Someone once said:\n\n> Scala people don't have time for redditing and blogging, they're busy getting crap done.\n\nWhich is exactly what we've been doing. Like Scala, Vue works really, really well, when used properly. It turns out Vue isn't a buzzword, Vue is a workhorse. A lot of our problems have been solved, by us and others. We still have problems but, we now have a reproducible \"way to write Vue.\" We don't adopt every new idea out there, but we have changed a few things since we last spoke.\n\nSince that last post, we published a [very extensive Vue style guide](https://docs.gitlab.com/ee/development/fe_guide/vue.html), after which Vue also put out a [style guide](https://vuejs.org/v2/style-guide/), [taking inspiration from ours](https://github.com/vuejs/eslint-plugin-vue/issues/77#issuecomment-315834845). The style guide has been updated several times as we discover better ways to write Vue. Here are some of the things we discovered.\n\n## Just use VueX\n\nWe discovered that [VueX](https://vuex.vuejs.org/) makes our lives easier. If you are writing a medium to large feature, use VueX. If it's a tiny feature, you might get away without it. We made the mistake of not using VueX for a large feature. We wrote a [multi-file editor](https://gitlab.com/gitlab-org/gitlab-ce/issues/31890) (WIP) to replace our current repo file view, to allow easy editing of multiple files.\n\n![multi-file-editor.png](https://about.gitlab.com/images/vue_2017/multi-file-editor.png){: .shadow}\n\nIn the beginning we did not use VueX for this feature and instead used the store pattern. The Vue docs talk about the [store pattern](https://vuejs.org/v2/guide/state-management.html#Simple-State-Management-from-Scratch), which works well when you are committed to strictly keeping to the pattern. We've found that you are better off spending your time with VueX instead. While VueX is initially more verbose, it is much more scalable, and will save you tons of time in the long run. Our mistake happened when we changed the data in multiple places. In VueX you are forced to change the data in one central place. If you don't do this, you will wind up chasing unexpected bugs around.\n\n## Write high quality code\n\nEven though VueJS and VueX are both wonderful, it is still possible (as with any code) to write bad Vue code. While the code may work, your longevity and scalability may suffer. Performance can suffer. With Vue, it makes it so easy to have what seems like working, perfect code because Vue is so simple to write. Longevity problems can mean that your code initially works, but you (and others) will have a hard time trying to update the code. Performance problems might not crop up with small data sets, but will with larger ones. Code can get messy. Your code can get smelly. Yes, even with Vue, you can have [code smell](https://en.wikipedia.org/wiki/Code_smell).\n\nWhen you add something to the `data` object or the `store` for Vue to keep track of, Vue will recursively walk down your data object and keep track of everything. If your data is super hierarchical and just large in general, and you are changing things often (like maybe on `mousemove`), then you can create jank. It's not bad to have Vue observe large data sets, but just confirm that you do in fact need the data you are watching to be reactive. It's easy with Vue to just make everything reactive, when it might not need to be.\n\nThat's why we are very strict when anyone writes Vue code. They must [follow our documentation](https://docs.gitlab.com/ee/development/fe_guide/vue.html). They must also only write Vue when it is necessary and not write it [when it is overkill](https://docs.gitlab.com/ee/development/fe_guide/vue.html#when-not-to-use-vue-js).\n\nAll of our new Vue code follows the [Flux architecture](https://facebook.github.io/flux/). VueX also follows Flux, which is part of the reason we use VueX. You can use the previously mentioned \"store pattern,\" but VueX is a better choice because it enforces all of the rules. If you go rogue, you will wind up enforcing the rules yourself, and you will probably make mistakes. The less you put on your plate, the better. A good example of a well-written Vue app is the [registry image list](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/14303).\n\n### I want to use jQuery with Vue\n\nDuring new development, this question kept popping up.\n> Is it ever OK to mix jQuery with VueJS?\n\nWe are not talking about using [Select2](https://select2.org/), which is a jQuery library. We are talking about the need to query the DOM. We had discussions about using jQuery and the following was proposed:\n\n> Using jQuery is OK, but only for querying.\n\nAt first I had several discussions about using jQuery with Vue. Some had said it might be OK, but only in read-only (querying) situations. However, after doing the research, we found that it is **not** a good idea to use jQuery with Vue. There will always be a better solution. We found that if you ever find yourself needing to query to DOM within a Vue architecture, then you are doing something wrong.\n\nIf one were to hypothetically use jQuery for only the tiniest querying situations, one would have to quantify those situations. You should instead swear off querying the DOM when in Vue.\n\nInstead of querying, you will find that using the `store` in combination with the server-side code is usually a much simpler answer. The server can provide validity to your data that you cannot provide on the client side. For the most part, we find that the less we have to fool with the data on the client side the better. That's not to say it's never OK to modify the data on the client side, but that it isn't usually the cleanest solution. At GitLab we use querying only to grab endpoints from the `data` attribute of our main element, but we don't use jQuery, we use `el.dataset`. At GitLab, we (the Frontend people) talk with the Backend people to ensure the structure of the data we will be consuming. In that way, both the Frontend team and the Backend team can be in control.\n\n#### Example situation:\n\nCheck out this issue:\n\n![issue](https://about.gitlab.com/images/vue_2017/issue.png)\n\nWe now render all issue comments in Vue. An example of a situation where we wanted to use jQuery was during the rewrite of the edit-the-last-user-comment feature. When someone presses that `up` key on their keyboard from an empty new comment `textarea` (at the very bottom of the page) we allow them to edit the last comment they created, just like in Slack. Not just the last comment, but the last comment *they created*. We marked the last user comment in the picture in red. Of course there is a time crunch. Then someone might say,\n\n> Can't we just do a quick solution here and fix it later?\n\nSurely you *could* query the DOM for this. A better solution, in this case, is to let the backend developers mark the last user comment in the JSON they return. Backend developers have direct access to the database, which means they may be able to optimize the code. Then no client-side work has to be done at all, in this case. Someone has to do the work to mark the last user comment. In this case the solution is just finding the right person for the job. Once you have that data from the server, the comment is in your `store`, ready for your easy access. You can do anything now. The world is your oyster.\n\nIf you find yourself querying the DOM, \"just this one time\" 😉, there is always a better solution.\n\n### The proper Vue app\n\nEvery Vue bundle needs one store, one service, and always has one entry point. Your entry point component is the only container component and every other component is presentational. All this information is in our Vue docs.\n\nYou can start out with a single `div`.\n\n```html\n\u003C!--HAML-->\n.js-vue-app{ data: { endpoint: 'foo' }}\n\n\u003C!--HTML-->\n\u003Cdiv class=\"js-vue-app\" data-endpoint=\"foo\">\u003C/div>\n```\nYou can pass your endpoints in through the data attributes. Vue can then call these endpoints with an HTTP client of your choice.\n\nYou don't want to do any URL building in client-side JavaScript. Make sure you pass in all your server-built URLs through endpoints. When writing Vue it's important to let the server do what it should.\n\n## Improve performance\n\nWe recently rewrote our issue comments in Vue. The issue comments were previously written in Haml, jQuery, and Rails. We had a bottleneck because we were not loading the comments asynchronously. A quick solution is to load comments via ajax and populate comments after the page loads. One way to make a page load faster is to not block the page with heavy items and load them after.\n\n![comments.png](https://about.gitlab.com/images/vue_2017/comments.png){: .shadow}\n\nWhat we love is that one day we turned on the new comments and some people didn't know that we had refactored it. As a result of the refactor our issue pages load much faster, and there is less jank.\n\nLoading the comments on the issue page is now streamlined and now individual issues load much faster. In the past, an issue page could have tens of thousands of event listeners. Our previous code was not properly removing and keeping track of event listeners. Those massive event listeners (along with other problems) created jank, so scrolling the page was choppy with many comments. We removed jQuery and added in Vue and focused on improving the performance. You can clearly see and feel that the page is much faster. However, our work to improve the performance has just begun. This rewrite sets the foundation for performance improvements that are easier to write, because the code is much more maintainable. Previously the code was hard to maintain. Now the issue comments code is properly separated and \"componentized.\"\n\nWith these new improvements, as well as other parallel improvements, e.g. loading images on scroll, we were able to make the page load and perform faster.\n\n![speed.png](https://about.gitlab.com/images/vue_2017/speed.png)\n\nRefactoring is that word that a new, super-green developer mentions on day one when they suggest to rewrite everything in Angular. That hasn't happened at GitLab. Our frontend devs tend to be very conservative, which is a very good thing. Which begs the question, why does it seems like [everyone is always refactoring](https://reasonml.github.io/community/blog/#reason-3)? What are they trying to achieve? I can only speak for GitLab. What do we want to achieve with a refactor? In reality it's going to cost a lot of money. The costs are:\n\n1. Cost of doing the refactoring.\n1. Cost of testing the change.\n1. Cost of updating tests and documentation.\n\nYou also have more risk:\n\n1. Risk of introducing bugs.\n1. Risk of taking on a huge task that you can't finish.\n1. Risk of not achieving the quality/improvements you intended.\n\nOur goals are:\n\n**Goal #1**: Make the code more maintainable. We want to make the process of adding new features easier. In the long term this refactor will save us time, but it takes a significant amount of time to recoup the time spent refactoring. The hard truth may be that a refactor usually does not save you time, but can save you stress.\n\n**Goal #2**: What it can do, if done right, is make developers happy. Nothing gives your team more horsepower than a happy, excited coder. A stressed-out coder will want to stop coding; an excited coder will not want to stop. A happy coder saves the most time.\n\nTo meet our goal our next step is to refactor the merge request comments section. Our merge request comments are massively slow for merge requests with lots of comments. The comments become slower and start to be less responsive at around 200 comments. The diffs are slow as well. There are a ton of reasons for this, one of which is that JavaScript is causing multiple reflows that take tons of time. We could refactor this and have already put in a fix, but this isn't a long-term solution.  In the case of a huge MR, there was code that was causing a reflow that [takes over eight seconds](https://gitlab.com/gitlab-org/gitlab-ce/issues/39332)! This is now fixed. In this [image](https://gitlab.com/gitlab-org/gitlab-ce/uploads/e18856a1544d4d0e6420d11fd0479af7/ss__2017-10-20_at_1.41.04_PM.png) you can see there is other stuff slowing things down. Clearly there is a lot of work to do here. Our biggest problem is that the code is not maintainable, which means that fixes take longer. A refactor into Vue will provide some great initial speed improvements, and lay the groundwork for easier improvements in the future.\n\nThere is so much work to do at 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/)",[714,715,716],"tutorial","product","features",{"featured":12,"template":13,"slug":718},"using-gitlab-container-virtual-registry-with-docker-hardened-images",{"content":720,"config":730},{"title":721,"description":722,"authors":723,"heroImage":725,"date":726,"category":9,"tags":727,"body":729},"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":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",[611,259,715],"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.
