### JVM Settings

Keycloak sets the following system properties by default:
`-Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true`
`-Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m`

You can override these by setting the `JAVA_OPTS` environment variable.
Make sure you configure container support.

Alternatively one can append custom JVM options by setting the `JAVA_OPTS_APPEND` environment variable.
