Google cloud platform 调整节点配置代理和调度程序

今天，我尝试更改支持cloud composer环境的集群的节点类型，并切换到Ubuntu映像，而不是COS。为此，我向GKE集群添加了第二个节点池，然后删除了第一个节点池，并迁移了所有工作负载

这会在sqlproxy日志中产生以下错误：

couldn't connect to "XXXXX:europe-west1:XXXXX": ensure that the Cloud SQL API is enabled for your project (https://console.cloud.google.com/flows/enableapi?apiid=sqladmin). Error during createEphemeral for XXXXX:europe-west1:XXXXX: googleapi: Error 403: Insufficient Permission, insufficientPermissions

调度程序无法完全启动，并发出以下堆栈跟踪：

与支持SQL数据库的连接现在似乎已断开。它仍然是相同的集群，但节点不同。是否需要更新其他配置？

SQLProxy依赖于用于创建Composer环境的服务帐户的凭据。如果不更改任何设置，则这应该是计算引擎的默认服务帐户

您应该验证新节点池和
