# StatefulSet variant of the dind example.
#
# Unlike the Deployment, a StatefulSet gives each replica a stable identity and,
# via volumeClaimTemplates, its own persistent volume. That means every runner
# pod keeps its own `.runner` registration file across restarts and reschedules,
# so it re-attaches to the server instead of trying to register again.
apiVersion: v1
data:
  # The registration token can be obtained from the web UI, API or command-line.
  # You can also set a pre-defined global runner registration token for the Gitea instance via
  # `GITEA_RUNNER_REGISTRATION_TOKEN`/`GITEA_RUNNER_REGISTRATION_TOKEN_FILE` environment variable.
