helm-charts/ci/keycloak/fixtures.yaml

# Fixtures for the keycloak install-test: a throwaway PostgreSQL plus the two
# Secrets the 1Password operator would otherwise materialize from the
# OnePasswordItems the chart renders (release name: ci, stub CRD in ci/common/).
#
# WHY A REAL DATABASE AND NOT A STUB: Keycloak does nothing without one. It
# creates its entire schema through Liquibase on first start, and - the reason
# this fixture is the valuable half of the test - jdbc-ping discovers the second
# replica THROUGH this database. A stub would turn a cluster test into a
# templating test.
#
# The image is pinned to a major line like every other fixture here
# (postgres:16-alpine); ci/** is excluded from Renovate on purpose, because
# this is test scaffolding and churning it only risks breaking the
# install-test.

  # The field NAMES are what matters here, not the values: the operator

  # these two by name. A rename on either side leaves the pod in
  # CreateContainerConfigError, which is a state no render can show.
  #
  # They must agree with the POSTGRES_USER / POSTGRES_PASSWORD below, because
  # Keycloak really connects.

  # deleted with the job, and the only thing it protects is a realm that exists

    # The reason the issue was opened: Keycloak has no logo field on an identity
    # provider, so the icon on its login button comes only from a login theme.
    # Nothing in CI drives a browser, so this line is carried rather than
    # checked - what the run proves is that the theme reaches the container.
