Keycloak Production Readiness Checklist

· 14 min read

A Keycloak production readiness checklist has to answer two different questions, and most published ones only answer the first. Keycloak's start command refuses to boot until you settle two things, and it prints a clear error for each, so those are easy. The harder list is everything it will happily let you ship wrong: brute force protection is off, your audit log accepts forged IP addresses from anyone, event tables grow forever, and the readiness endpoint disagrees with your load balancer for the first few seconds of every restart.

Everything below was run against quay.io/keycloak/keycloak:26.7.3. Where a number appears, it came out of a terminal, not from memory.
