.gitlab-ci-check-docker-release-indep.yml

# .gitlab-ci-check-docker-release-indep.yml
#
# This gitlab-ci template publishes Docker images on tags for independent
# components
#
# It depends on .gitlab-ci-check-docker-build.yml, so both need to be
# included for the process to work.
#
# Add it to the project in hand through Gitlab's include functionality
#
# include:
#   - project: 'Northern.tech/Mender/mendertesting'
#     file: '.gitlab-ci-check-docker-release-indep.yml'
#
# It does not has explicit requirements. It assumes that the requirements
# for .gitlab-ci-check-docker-build.yml are satisfied.
#
# On release candidate tag, it publishes the image after successful build and test
# On final release rag, it re-tags the last release candidate as final release
#

stages:
  - build
  - publish
