Keycloak

Keycloak container image for Kokuwa.

Features

• BaseImage:
  • debian:stable-slim (amd64 & arm64)
  • eclipse-temurin:17-jre (amd64 & arm64)
  • distroless/java17:nonroot (amd64)
• preconfigured with PostgeSQL
• preconfigured for Kubernetes:
  • health enabled
  • quarkus metrics enabled
  • keycloak metrics enabled (see keycloak-event-metrics) with model names
  • logs as json
  • run with uid:gid 1000:1000
• integration test with k3s and deployment of example theme

Why

in June 2022 no preconfigured Keycloak container image without legacy Keycloak was available.

Use this image if you intend to:

1. use Keycloak in Quarkus version, not Wildfly version
2. use PostgeSQL as backend
3. no need for auto-build for faster startup
4. run Keycloak not as root
