# Runs the deployer module to validate clusters. This will both validate | |
# cluster.yaml files, any non-encrypted values files for the support chart (if they | |
# exist), as well as each hubs passed non-encrypted values files against the Helm | |
# charts' values schema. | |

jobs: | |
# This job inspects changed files in order to determine which cluster files | |
# should be validated. If helm-chart files change, then all clusters will be | |
# validated. The output of this job is a json-encoded dictionary of the | |
# cluster names to be validated. This is passed to the | |
# validate-helm-charts-values-files job to define a matrix strategy. | |
# We also set a continue_workflow job output that determines if either the | |
# common or cluster_specific files have changed and whether the next job | |
# should be run. We always run the next job if the workflow was manually | |
# triggered. | |
# | |
# === Notes on dorny/paths-filter syntax === | |
# 1. Setting 'list-files: csv' sets an output called '${FILTER_NAME}_files' | |
# that we use to determine which specific clusters have file changes | |
# 2. The 'added|modified:' syntax before a path glob pattern means that we | |
# only care about files that have been added or modified, not deleted | |
# 3. We can also group filters together and hence only need to run the action | |
# step *once* with the 'common' and 'cluster-specific' filters together | |
