Thank you @esselesse! This is a variation I am using (PostgreSQL is configured as an external service).

  REDASH_MAIL_SERVER: vm.eradman.com

Notes

1. clusterIP is normally assigned a service proxy address. None allows CoreDNS to return the endpoint.
2. This deployment also sets up a worker dedicated to the periodic queue, which is required under heavy load to prevent Redis keys from incorrectly expiring.

Initial setup

alias redash-exec='kubectl exec -ti $(kubectl get pods -l app=redash -o name)'
redash-exec -- ./manage.py database create_tables
redash-exec -- ./manage.py db upgrade
redash-exec -- ./manage.py users create_root eradman@eradman.com Redash --password '******'
