# Gitea Initialization Job
# This Job runs after Gitea is installed to create the initial repository
# It uses the same admin credentials from gitea-admin-secret
#
# Apply after Gitea is ready:
#   kubectl apply -f gitea-init-job.yaml -n gitea
#
# To re-run (if needed):
#   kubectl delete job gitea-init-repo -n gitea
#   kubectl apply -f gitea-init-job.yaml -n gitea
