Iron Bank image does not support Redis
This chart now uses the Iron Bank image based on v0.3.1 (released upstream on Apr 10, 2020).
But Redis support was added to authservice upstream after that release and is only available if building from upstream master
:

This Helm chart advertises support for multiple replicas and Redis support, but this doesn't work with the Iron Bank image.
If you attempt to use the Iron Bank image you will get the following error during startup:
[2021-02-23 21:26:36.142] [console] [error] main: Unexpected error: (chains[1].filters[0].oidc) redis_session_store_config: Cannot find
field.
Reverting to the Big Bang image works:
