# K8s E2E Suite
#
# This workflow runs under any of the following conditions:
#    - manual dispatch in GH UI
#    - on a PR commit if the kubernetes_logs source was changed
#    - in the merge queue
#    - on a schedule at midnight UTC Tue-Sat
#    - on demand by either of the following comments in a PR:
#        - '/ci-run-k8s'
#        - '/ci-run-all'
#
# If the workflow trigger is the nightly schedule, all the k8s versions
# are run in the matrix, otherwise, only the latest is run.

  # In flight runs will be canceled through re-trigger in the merge queue, scheduled run. The comment.html_url should always be unique.
  # Note that technically this workflow can run on PRs which have code changes that affect K8s. Choosing not to add the PR commit to
  # the concurrency group settings- since that would result in new PR commits canceling out manual runs on any PR that doesn't flag
  # change detection. This is a "conservative" approach that means we may have some runs that could be canceled, but it's safer than
  # having user's runs canceled when they shouldn't be. In practice this shouldn't happen very often given this component does not change
  # often so any increased cost from the conservative approach should be negligible.
