# Auto DevOps
# This CI/CD configuration provides a standard pipeline for
# * building a Docker image (using a buildpack if necessary),
# * storing the image in the container registry,
# * running tests from a buildpack,
# * running code quality analysis,
# * creating a review app for each topic branch,
# * and continuous deployment to production
#
# In order to deploy, you must have a Kubernetes cluster configured either
# via a project integration, or via group/project variables.
# AUTO_DEVOPS_DOMAIN must also be set as a variable at the group or project
# level, or manually added below.
#
# If you want to deploy to staging first, or enable canary deploys,
# uncomment the relevant jobs in the pipeline below.
#
# If Auto DevOps fails to detect the proper buildpack, or if you want to
# specify a custom buildpack, set a project variable `BUILDPACK_URL` to the
# repository URL of the buildpack.
# e.g. BUILDPACK_URL=https://github.com/heroku/heroku-buildpack-ruby.git#v142
# If you need multiple buildpacks, add a file to your project called
# `.buildpacks` that contains the URLs, one on each line, in order.
# Note: Auto CI does not work with multiple buildpacks yet

variables:
# AUTO_DEVOPS_DOMAIN is the application deployment domain and should be set as a variable at the group or project level.
