Mac m4 JAVA_TOOL_OPTIONS=-XX:UseSVE=0

Configuring the server

I was having trouble getting the keycloak operator to work.

Long story short, basically download the operator yaml and add env var JAVA_TOOL_OPTIONS to the yaml. I think this should be documented.

https://raw.githubusercontent.com/keycloak/keycloak-k8s-resources/26.2.0/kubernetes/kubernetes.yml

    spec:
      containers:
        - env:
            - name: JAVA_TOOL_OPTIONS
              value: -XX:UseSVE=0

You can test locally …

docker run --rm -it quay.io/keycloak/keycloak-operator:26.2.0 bash

Result

Passing JAVA_TOOL_OPTIONS works

 docker run --rm -it -e JAVA_TOOL_OPTIONS=-XX:UseSVE=0 quay.io/keycloak/keycloak-operator:26.2.0 bash
