Gitlabracadabra

🧹 GitLabracadabra 🧙

⚗️ Adds some magic to GitLab 🔮

GitLab'racadabra is a GitOps way to configure a GitLab instance from a YAML configuration, using the API.

It is able to create GitLab's groups, projects, users and application settings.

👍 It's also able to mirror :

• Git repositories, using the mirrors parameter in Mirroring repositories.
• container (Docker) images, using the image_mirrors parameter. See Mirroring container images.
• packages, using the package_mirrors parameter. See Mirroring packages.

It is based on Python GitLab.

Installation

Using Debian packages

Debian package is available from artifacts and can be installed with:

apt install gitlabracadabra_*.deb

gitlabracadabra --verbose --dry-run

Note: Debian 11 bullseye or later is required.

Using pip

pip install gitlabracadabra

Using docker image

There are also Docker/OCI images.

Example usage:

sudo docker run -ti \
  -v "$HOME/.python-gitlab.cfg:/home/gitlabracadabra/.python-gitlab.cfg:ro" \
  -v "$PWD/gitlabracadabra.yml:/app/gitlabracadabra.yml:ro" \
  'registry.gitlab.com/gitlabracadabra/gitlabracadabra:v2.5.0' \
  --verbose --dry-run

Other images are available. Examples:

• registry.gitlab.com/gitlabracadabra/gitlabracadabra/main: Current main
• registry.gitlab.com/gitlabracadabra/gitlabracadabra/main:b1cd3482bf9583c5db863c359e12cafcdb7119bf: A specific commit of main

Configuration

GitLabracadabra uses the same configuration file as Python GitLab CLI to store connection parameters.

Example ~/.python-gitlab.cfg:

[global]
default = gitlab

[gitlab]
url = https://gitlab.com
private_token = T0K3N

More information in Python GitLab documentation.

Alternatively, you can use the following environment variables:

• GITLAB_URL: GitLab URL
• GITLAB_PRIVATE_TOKEN or GITLAB_OAUTH_TOKEN: authentication
• GITLAB_TLS_VERIFY: either true or false, or a CA path. Ignored when emty.

Action file(s)

GitLabracadabra actions are configured with a YAML file.

See GitLabracadabra's own action file or read:

• Action file syntax
• list of parameters:
  • for projects
  • for groups
  • for users
  • for application settings

Using gitlabracadabra in GitLab CI

Since job token probably won't have enough permissions, you'll need to use a personal access token:

• create a personal access token
• Define the GITLAB_PRIVATE_TOKEN protected variable
• Use it in your jobs to configure python-gitlab. Example .gitlab-ci.yml:

default:
  image:
    name: 'registry.gitlab.com/gitlabracadabra/gitlabracadabra:v2.5.0'
    entrypoint: [""]
  before_script:
    - |
        cat << EOF > ~/.python-gitlab.cfg
        [global]
        default = gitlab
        [gitlab]
        url = ${CI_SERVER_URL:-https://gitlab.com}
        private_token = ${GITLAB_PRIVATE_TOKEN}
        # job_token = ${GITLAB_JOB_TOKEN}
        EOF

stages:
  - test
  - deploy

test:
  stage: test
  script:
    - gitlabracadabra --verbose --dry-run
  rules:
    - if: '$CI_COMMIT_BRANCH != "main"'

apply:
  stage: deploy
  script:
    - gitlabracadabra --verbose
  rules:
    - if: '$CI_COMMIT_BRANCH == "main"'

Contributing

• File bugs and feature requests in GitLab issues. Security issues should be marked as confidential.
