I want to reformat the default logging output to json format without code changes

Docker image: jboss/keycloak:16.1.1

The current log structure is the default

15:04:16,056 INFO  [org.infinispan.CLUSTER] (thread-5,null) [Context=authenticationSessions] ISPN100002: Starting rebalance with members [], phase READ_OLD_WRITE_ALL, topology id 2
15:04:16,099 INFO  [org.infinispan.CLUSTER] (thread-20,) [Context=offlineClientSessions] ISPN100002: Starting rebalance with members [], phase READ_OLD_WRITE_ALL, topology id 2

I tried to use LOG_CONSOLE_OUTPUT as described here https://www.keycloak.org/server/logging but it's not working.

Any ideas please?

Assuming you want to use quarkus based Keycloak: Json logging for the quarkus based keycloak is only available since v18, see the release notes - the guides are at the moment referencing only the latest version.

I heavily recommend to update to this version. Then you could use the log console output variable.

You find the newer container images at quay instead of dockerhub since v17.

The link you posted is a tutorial for the Quarkus-based distro. However, your docker image is based on Wildfly.

Here is a Youtube video which explains how to configure json logging with Wildfly-based distro.
