How GitLabForm brings configuration-as-code discipline to the messy reality of managing dozens (or hundreds) of GitLab projects

Picture this: your team just onboarded three new projects. You need to protect the main branch, add the shared deploy key, configure merge request approval rules, wire up the Slack webhook, and set the right CI/CD variables — on every single project. So you log into GitLab, click your way through the settings UI, and repeat the same steps three times, hoping you didn’t miss anything.

Sound familiar? That’s exactly the problem GitLabForm was built to solve.

What is GitLabForm?

GitLabForm is an open-source, configuration-as-code tool purpose-built for GitLab. Instead of clicking through the UI or writing one-off API scripts, you describe how your GitLab groups, subgroups, and projects should be configured in a single YAML file — and let GitLabForm handle the rest.

One config file. Hundreds of projects. GitLabForm applies settings hierarchically — define something once at the group level, and it automatically cascades down to every project underneath. Exceptions? Override just what you need.

At its core it’s deceptively simple. Here’s what a group-wide merge request policy looks like in practice:

config.yml — group-level policy with a project exception

projects_and_groups:
  a_group/*:
    merge_requests_approvals:
      disable_overriding_approvers_per_merge_request: true

  a_group/a_special_project:
    merge_requests_approvals:
      disable_overriding_approvers_per_merge_request: false

That’s it. The first block applies to every project in the group. The second overrides exactly one setting for one special project. No scripts, no API calls, no clicking.

The Real Use Cases

GitLabForm covers a surprisingly wide surface area of GitLab configuration. Whether you’re a platform engineer managing a large self-hosted GitLab instance or a DevOps lead keeping dozens of microservice repos consistent, there’s a use case here for you.

  • Standardizing CI/CD variables across all projects in a team — no more secrets getting out of sync between repos.
  • Enforcing branch protection rules at scale — who can push, who can merge, whether force-push is allowed, and code owner requirements.
  • Managing team membership — adding or removing users and groups, setting access levels, and optionally enforcing that no one else has been manually added.
  • Deploy key management — roll out a new SSH key to every project in a group with three lines of YAML and a single command.
  • Webhook and integration setup — configure your Slack, Jira, or custom webhooks consistently, without copy-pasting across projects.
  • Repository files and templates — push standard files (like .gitignore or pipeline templates) to all projects using Jinja2-powered templating.
  • Pipeline schedules and protected environments — define these once and propagate them everywhere.

Why It Matters in the DevOps Ecosystem

Modern DevOps teams preach everything-as-code — infrastructure, pipelines, policies, observability. Yet GitLab configuration itself often remains a sprawling mess of manual clicks and tribal knowledge. GitLabForm closes that gap.

The Hierarchy That Changes Everything

The killer feature isn’t any single configurable item — it’s the three-level inheritance model. Configuration can be defined at three levels:

Common ("*") → applies to everything. Group/subgroup → applies to all projects in a group. Project → applies to one specific project.

More specific levels overwrite or extend less specific ones. So you might set a default visibility of internal globally, make everything under a sensitive team’s group private, and then explicitly set one open-source repo back to public. Three lines across three levels.

“GitLabForm lets you think about configuration the same way you think about code — with inheritance, overrides, and a single source of truth.”

Need to prevent a project from inheriting a parent’s deploy keys? Drop in inherit: false under that section. Need to skip configuration for a specific project entirely? Use skip: true. The tool is designed to feel expressive, not constraining.

Getting Started Is Genuinely Easy

No complex setup, no heavy dependencies. If you have Docker, you’re one command away from applying your first configuration:

Run via Docker

docker run -it -v $(pwd):/config \
  ghcr.io/gitlabform/gitlabform:latest \
  gitlabform my-group

Prefer pip? pip install gitlabform works too. Your config.yml just needs a GitLab URL, an admin token (or use the GITLAB_TOKEN env variable), and your desired state.

Who’s Already Using It?

GitLabForm isn’t a weekend project — it’s trusted in production by companies like Roche, Egnyte, Elastic Path, and Liquid Light, among many others. It’s actively maintained, follows semver strictly, and ships deprecation warnings before any breaking changes. That’s a level of maintainer care that’s worth calling out.

The Bottom Line

If your team runs more than a handful of GitLab projects and you care about consistency, auditability, and not repeating yourself — GitLabForm is the tool you didn’t know you were missing. It brings the same discipline we apply to infrastructure and pipelines to the layer of GitLab configuration that’s usually left to chance (and whoever has admin access that day).

Your GitLab instance’s configuration is infrastructure. Treat it that way.
