# Secrets:
#   switchboard-db-credentials  - POSTGRES_USER, POSTGRES_PASSWORD
#   switchboard-admin           - username, password, email (optional)
#
# Admin bootstrap: on every pod start, if SWITCHBOARD_ADMIN_* env vars
# are set, the backend upserts an admin user. Change the secret and
# restart the pod to reset the admin password.
