Deploy and Host GitLab CE on Railway

GitLab Community Edition is the open-source, self-hosted DevOps platform from GitLab Inc. It combines Git repository hosting, merge requests, issue boards, wikis, built-in CI/CD pipelines (runners connect separately) and a package registry in one web application, so a team can keep its code and its workflow on its own server.

About Hosting GitLab CE

GitLab CE ships as the official Omnibus image, which bundles Puma, Sidekiq, Gitaly, Workhorse, NGINX, PostgreSQL and Redis in one container. Hosting it means giving that container enough memory (about 3 GB in use, 4 GB recommended), keeping its data, configuration and encryption keys on persistent storage, and pointing its external URL at the public domain. This template runs the pinned official image as one Railway service with one volume, sets the external URL from the Railway domain, trims Puma, Sidekiq and the bundled monitoring stack to fit a modest plan, creates the root admin with a generated password, and closes public sign-up before the first request is served.

Common Use Cases

• Private Git hosting for a team or company, with merge requests and code review
• Issue tracking, boards, milestones and wikis next to the code
• CI/CD pipelines with your own GitLab Runner connected over HTTPS

Dependencies for GitLab CE Hosting

• The official gitlab/gitlab-ce Docker image (Omnibus package, PostgreSQL and Redis bundled)
• One Railway volume mounted at /var/opt/gitlab

Deployment Dependencies

• GitLab Docker install docs: https://docs.gitlab.com/install/docker/
• GitLab CE image on Docker Hub: https://hub.docker.com/r/gitlab/gitlab-ce
• GitLab releases: https://about.gitlab.com/releases/categories/releases/
• Running GitLab in a memory-constrained environment: https://docs.gitlab.com/omnibus/settings/memory_constrained_envs/

Implementation Details

• Image: gitlab/gitlab-ce:19.5.4-ce.0, pinned by digest.
• Login: user root, password in the service variable GITLAB_ROOT_PASSWORD (generated at deploy). It only applies on the first boot; change it later in GitLab itself.
• One volume: Railway gives a service one volume, so the start command keeps /etc/gitlab (including gitlab-secrets.json and the SSH host keys) and /var/log/gitlab inside /var/opt/gitlab/.railway through symlinks. Your repositories, database and encryption keys survive redeploys.
• Safe first boot: on the first start the wrapper turns off public sign-up and sets clone URLs to HTTPS only, then turns the health check (/assets/railway_health) green. The first boot takes about 2–7 minutes. You can re-enable sign-up under Admin > Settings > General.
• Your own settings: add a GITLAB_OMNIBUS_CONFIG variable (for example SMTP settings); it is applied after the template's defaults. Set GITLAB_EXTERNAL_URL if you attach a custom domain.
• Git over SSH is not exposed; use HTTPS with a personal access token. Plan for 4 GB of RAM or more.

Why Deploy GitLab CE on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying GitLab CE on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.
