# Ory Kratos — identity service for honeyDue.
#
# Deployed once the operator has completed the prerequisites in kratos/README.md
# (Neon `kratos` database, auth.myhoneydue.com DNS, Apple Sign In OIDC client,
# and the kratos-secrets Secret). Until then 03-deploy.sh skips the Kratos
# apply, so the existing stack is unaffected.
#
# IMAGE: pinned to oryd/kratos v26.2.0 (CalVer current stable as of 2026-06-03)
# with the linux/amd64 digest. The schema-migration Job is in migrate-job.yaml
# and runs before this Deployment rolls.
#
# OIDC: currently Apple-only (configmap.yaml providers[0]). Google was scoped
# out at deploy time; adding it later is additive — append to providers[] in
# configmap.yaml and add the matching CLIENT_SECRET env binding here.
