I’m running keycloak:9.0.3 on Docker Swarm with mssql and JDBC_PING as discovery protocol. I noticed that infinispan start to fail when a container is shut down with the following exception: Step to reproduce Run 3 replicas (different nodes) into Docker swarm with mssql and JDBC_PING configured w…

Hi If it is helpful we are using KUBE_PING with Kubernetes cluster. Our DevOps engineer create service account with RBAC and pods saw each other

Hey, thanks for your reply! Unfortunately, Kubernetes is not an option since the company uses Docker Swarm :confused:

Hey, Thanks for your suggestion, I’ll give it a try. Regarding 15c5b97 Basically, you removed PING and MPING protocols from configuration. Is it ok? Since I’m using 9.0.3 I’ll create a custom start up script.

Yeah, sure. You need to have (at least) one discovery protocol in your stack. MPING/PING/JDBC_PING are all different implementation of the discovery protocol.

Hi @slaskawi , After some tests, errors deleting ping data disappear, but downtime is still a concern with 500 errors. [infinistpan-error-2] Is there a way to avoid this kind of errors? I’m thinking about changing the discovery timeout to a lower value, configure the cache to be async? Any help…

It seems to be working with Keycloak 11.0.2 + JDBC_PATCH I’ll keep you posted after a while [image] Thanks!

Keycloak fails when its deployed, scale-in and/or scale-out

Configuring the server

We finally managed to merge one of my fixes for JDBC_PING: https://github.com/keycloak/keycloak-containers/pull/255

It should get better.
