GitLab CI

Below are some example GitLab CI jobs that use GoReleaser to release a project.

If you are using private hosted or Enterprise version of Gitlab, please follow this guide before diving into the details.

Basic Releasing

You can easily run GoReleaser in GitLab CI using its Docker container.

In the repository's GitLab CI settings, add a GITLAB_TOKEN variable. The value should be an API token with api scope for a user that has access to the project. This variable should be masked and optionally protected if the job will only run on protected branches and tags. See Quick Start for more information on GoReleaser's environment variables.

Add a .gitlab-ci.yml file to the root of the project:

stages:
  - release

release:
  stage: release
  image:
    name: goreleaser/goreleaser
    entrypoint: ['']
  only:
    - tags
  variables:
    # Disable shallow cloning so that goreleaser can diff between tags to
    # generate a changelog.
    GIT_DEPTH: 0
  script:
    - goreleaser release --rm-dist

Notice that entrypoint is intentionally blank. See the GitLab documentation on entrypoints for more information.

When tags are pushed to the repository, an available GitLab Runner with the Docker executor will pick up the release job. goreleaser/goreleaser will start in a container and the repository will be mounted inside. Finally, the script section will run within the container starting in your project's directory.

Releasing Archives and Pushing Images

Pushing images to a registry requires using Docker-in-Docker. To create GitLab releases and push images to a Docker registry, add a file .gitlab-ci.yml to the root of the project:

stages:
  - release

release:
  stage: release
  image: docker:stable
  services:
    - docker:dind

  variables:
    # Optionally use GitLab's built-in image registry.
    # DOCKER_REGISTRY: $CI_REGISTRY
    # DOCKER_USERNAME: $CI_REGISTRY_USER
    # DOCKER_PASSWORD: $CI_REGISTRY_PASSWORD

    # Or, use any registry, including the official one.
    DOCKER_REGISTRY: https://index.docker.io/v1/

    # Disable shallow cloning so that goreleaser can diff between tags to
    # generate a changelog.
    GIT_DEPTH: 0

  # Only run this release job for tags, not every commit (for example).
  only:
    refs:
      - tags

  script: |
    # GITLAB_TOKEN is needed to create GitLab releases.
    # DOCKER_* are needed to push Docker images.
    docker run --rm --privileged \
      -v $PWD:/go/src/gitlab.com/YourGitLabUser/YourGitLabRepo \
      -w /go/src/gitlab.com/YourGitLabUser/YourGitLabRepo \
      -v /var/run/docker.sock:/var/run/docker.sock \
      -e DOCKER_USERNAME -e DOCKER_PASSWORD -e DOCKER_REGISTRY  \
      -e GITLAB_TOKEN \
      goreleaser/goreleaser release --rm-dist

In GitLab CI settings, add variables for DOCKER_REGISTRY, DOCKER_USERNAME, and DOCKER_PASSWORD if you aren't using the GitLab image registry. If you are using the GitLab image registry, you don't need to set these.

Add a variable GITLAB_TOKEN if you are using GitLab releases. The value should be an API token with api scope for a user that has access to the project.

The secret variables, DOCKER_PASSWORD and GITLAB_TOKEN, should be masked. Optionally, you might want to protect them if the job that uses them will only be run on protected branches or tags.

Make sure the image_templates in the file .goreleaser.yml reflect that custom registry!

Example:

dockers:
-
  goos: linux
  goarch: amd64
  image_templates:
  - 'registry.gitlab.com/Group/Project:{{ .Tag }}'
  - 'registry.gitlab.com/Group/Project:latest'
