在Kubernetes pod中使用bitnami/keycloak部署/安装keycloak时，我一直收到OutOfMemoryError错误。

我怀疑这可能是因为Java堆的大小。如果我错了，请纠正我。
我已经检查了分配给机器的资源;一切看起来都很好。问题是如何更新value.yaml文件中的堆大小？https://github.com/bitnami/charts/blob/main/bitnami/keycloak/templates/configmap-env-vars.yaml中的JAVA_OPTS_APPEND是否是要覆盖的env变量？
如果有人有例子，请分享。

在16.0.0上，我设置：

extraEnvVars:
  - name: JAVA_OPTS_APPEND
    value: "-Xms2048m -Xmx4096m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Dfile.encoding=UTF-8 -Dsun.stdout.encoding=UTF-8 -Dsun.err.encoding=UTF-8 -Dstdout.encoding=UTF-8 -Dstderr.encoding=UTF-8 -XX:+ExitOnOutOfMemoryError -Djava.security.egd=file:/dev/urandom -XX:+UseParallelGC -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=20 -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=9"
