How to install Gitlab with Docker
GitLab is a complete DevOps platform that allows you to manage your Git repositories, run CI/CD pipelines, track issues, and much more. The official and most straightforward way to run a self-managed GitLab instance is by using their Docker image.
High System Requirements: GitLab is a resource-intensive application. We recommend a server with at least 4 CPU cores and 8 GB of RAM for a smooth experience.
Installation Steps
First, log into your server via SSH. Create a directory for your GitLab project and then create the docker-compose.yml file within it.
Create Directory and File
mkdir gitlab
cd gitlab
nano docker-compose.yml
Paste the following official configuration into the docker-compose.yml file:
docker-compose.yml
