Ansible Role: `bsmeding.gitlab_docker`

GitHub: ansible_role_gitlab_ce_docker
Ansible Galaxy: bsmeding.gitlab_docker

The following documentation is taken from the repository README.

This role installs GitLab Community Edition (CE) on a Docker host.

🛠️ Features

Deploy GitLab CE in Docker
Optional support for:
Custom ports
SSL (incl. registry certs)
LDAP (including Active Directory)
Optional GitLab Registry
Custom gitlab.rb configuration support
Simple environment variable configuration

🔐 Root Password

If the root password is not set via the GITLAB_ROOT_PASSWORD environment variable or in gitlab.rb (gitlab_rails['initial_root_password']), GitLab will auto-generate it.

The auto-generated password can be retrieved (within 24 hours) from:

/etc/gitlab/initial_root_password

To retrieve: 1. SSH into the host 2. Access the container:

docker exec -it gitlab /bin/bash

3. Display the password:

cat /etc/gitlab/initial_root_password

To manually disable public user signups, refer to the GitLab issue: 📎 Disable signups

👥 LDAP Support

LDAP is enabled when both of the following are set:

gitlab__ldap_server_host_ip
gitlab__ldap_server_host_port

Common LDAP Variables

Variable	Description
`gitlab__ldap_search_users`	Base DN to search for users
`gitlab__ldap_search_groups`	(Not implemented yet)
`gitlab__ldap_auth_bind_dn`	Bind DN for the LDAP search
`gitlab__ldap_auth_bind_pass`	Bind password
`gitlab__ldap_user_filter`	LDAP filter to limit access (e.g., by group)
`gitlab__ldap_is_ad`	Set to `true` for Microsoft Active Directory

🧑‍💼 Microsoft Active Directory

When using AD:

Set gitlab__ldap_is_ad: true

Use the proper memberOf OID for filters:

(memberOf:1.2.840.113556.1.4.194:=CN=...)

⚙️ gitlab.rb Configuration

By default, the role does not overwrite gitlab.rb if it already exists. Manual changes will persist across playbook runs unless related variables (like LDAP) are updated.

Custom settings can be injected via gitlab__gitlab_rb_user_config.

🔐 SSL Support

To enable SSL:

Place certificate files in ./files/certs/
Define in your playbook:

gitlab__ssl_cert_file: 'git.example.com.crt'
gitlab__ssl_cert_key_file: 'git.example.com.key'

To enable registry SSL:

gitlab__registery_ssl_cert_file: 'registry.example.com.crt'
gitlab__registery_ssl_cert_key_file: 'registry.example.com.key'

Trusted Root Certificates

To add trusted root CAs, place them in:

./files/certs/trusted-certs/

These will be copied into the container.

📦 Example Playbook

---
- name: Install GitLab CE
  hosts: gitlab_hosts
  become: true
  gather_facts: true

  vars:
    gitlab__hostname: git.example.com
    gitlab__env:
      GITLAB_ROOT_PASSWORD: 'pleasechangeme'

  tasks:
    - name: Install Docker
      ansible.builtin.include_role:
        name: bsmeding.docker

    - name: Deploy GitLab
      ansible.builtin.include_role:
        name: bsmeding.gitlab_docker

⚠️ First-time setup may take 5–10 minutes for GitLab to fully initialize.

🧪 TODO

Test without automatic user generation
Mount /etc/passwd to container for user mapping
