How to setup keycloak with render db

There are some other topics but nothing that worked for me, this is the Dockerfile I used that finally worked

Render Dockerfile deploy, this works with a render postgres database

It takes about 2-3 min to start up, you probably want to get Starter to prevent downtime.

Replace mykeycloaksite with your keycloack address, set the PORT env in your render deploy to 8443, and create an environment variable in your render deploy for all those ARGs to the values given by your db provider

Note that the dashboard will be at

/auth/admin

also sometimes when you spin up a new instance the old ones are slow to go away so that can clutter your logs, keep that in mind

Does anyone know how to fix

2024-04-26 17:34:43,614 WARN [org.jgroups.blocks.cs.NioServer] (NioServer.Selector [/[0:0:0:0:0:0:0:0]:24828]-3,srv-) failed handling message: java.lang.IllegalStateException: BaseServer.NioConnection.readPeerAddress(): cookie read by 10.xxx.xxx.xxx:24828 does not match own cookie; terminating connection

It seems to spam those a lot, it still works but I’d like to remove those warnings if possible

oh also if you want to use cockroach db instead this works for me

where CERT_PATH is the path of the cert it links you to when you try and connect using a general connection string
