Update a service

Use Duplo to update a service's container from Gitlab CI/CD

Update the docker image for a service

The goal of this section is to show how you can update the docker image for a service, after you have built that image.

Example Workflow

This example makes some assumptions:

• Your workflow already has a build job - we created one in the previous section

deploy:
  stage: deploy
  image:
    name: duplocloud/duploctl:v0.2.27
    entrypoint: [""]
  # this will have DUPLO_HOST and DUPLO_TOKEN
  environment:
    name: $TIER/$DUPLO_TENANT
    url: ${MYAPPS_URL}
  rules:
  # run when a new tag is pushed
  - if: $CI_COMMIT_TAG && $CI_PIPELINE_SOURCE == "pipeline"
    when: always
  variables:
    # build your image here
    CI_IMAGE: ${IMAGE_REGISTRY}/${CI_PROJECT_NAMESPACE}/${CI_PROJECT_NAME}:${CI_COMMIT_TAG}
    GIT_STRATEGY: none # no need to pull the repo
  needs:
  - job: publish_image
    optional: true
  before_script:
  - echo "Updating service ${CI_PROJECT_NAME} with image ${CI_IMAGE}"
  script: duploctl service update_image $CI_PROJECT_NAME $CI_IMAGE
