Kubernetes 仅当我向部署中添加第二个常规容器时，init容器的部署引发错误

您好，我目前正在尝试使用DB cloudsql实例在GKE中部署sonarqube 7.8-community

这需要2个容器（一个用于sonarqube，另一个用于cloudproxy，以便连接到DB）

然而，Sonarqube容器也需要一个init容器来满足一些特殊的内存需求

当我仅使用sonarqube映像和init容器创建部署时，它可以正常工作，但这没有任何用处，因为我需要cloudsql代理容器连接到外部数据库。当我添加这个容器时，部署突然出现以下错误

deirdrerodgers@cloudshell:~ (meta-gear-306013)$ kubectl create -f initsonar.yaml
The Deployment "sonardeploy" is invalid:spec.template.spec.initContainers[0].volumeMounts[0].name: Not found: "init-sysctl"

这是包含init容器和其他两个容器的完整yaml文件。我想知道问题是不是因为它不知道将init容器应用到哪个容器

您的yaml文件不正确。您有两个

spec:

块。应该只有一个。你需要把它结合起来。在

spec

下，block应该是

initContainers

block，然后是

containers

，最后是

volumes

block。查看下面正确的yaml文件：

您有两个

spec:

块；把它们结合在一起。在这种情况下，您应该有

initContainers:

，

containers:

，以及一个

卷：

，列出了两个卷（按任意顺序）。@DavidMaze这是有效的！非常感谢。
