GitLab CI

The following code sample demonstrates how to integrate Dagger with GitLab CI.

.gitlab-ci.yml

.docker:
  image: alpine:latest
  services:
    - docker:${DOCKER_VERSION}-dind
  variables:
    DOCKER_HOST: tcp://docker:2376
    DOCKER_TLS_VERIFY: '1'
    DOCKER_TLS_CERTDIR: '/certs'
    DOCKER_CERT_PATH: '/certs/client'
    DOCKER_DRIVER: overlay2
    DOCKER_VERSION: '20.10.16'
    # assumes the Dagger Cloud token is
    # in a masked/protected variable named DAGGER_CLOUD_TOKEN
    # set via the GitLab UI
    DAGGER_CLOUD_TOKEN: $DAGGER_CLOUD_TOKEN
.dagger:
  extends: [.docker]
  before_script:
    - apk add curl
    - curl -L https://dl.dagger.io/dagger/install.sh | BIN_DIR=$HOME/.local/bin sh
build:
  extends: [.dagger]
  script:
    # assumes a Go project
    # modify to use different function(s) as needed
    - dagger -m github.com/kpenfound/dagger-modules/golang@v0.1.5 call build --project=. --args=.
    # for ephemeral runners only: override the default docker stop timeout and
    # give the Dagger Engine more time to push cache data to Dagger Cloud
    - docker stop -t 300 $(docker ps --filter name="dagger-engine-*" -q)
