仅当我将第二个常规容器添加到我的部署时,才会为 init 容器部署抛出错误
deployment throwing error for init container only when I add a second regular container to my deployment
您好,我目前正在尝试使用数据库 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 以便连接到数据库)
然而,Sonarqube 容器也需要一个 init 容器来满足它一些特殊的内存要求。
当我仅使用 sonarqube 映像和 init 容器创建部署时,它工作正常,但这没有任何用处,因为我需要 cloudsql 代理容器连接到我的外部数据库。当我添加这个容器时,虽然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"
这是我包含初始容器和其他两个容器的完整 yaml 文件。我想知道问题是因为它不知道将 init 容器应用到哪个容器?

您的 yaml 文件不正确。你有两个 spec:
块。应该只有一个。您需要将它们组合在一起。在 spec
块下应该是 initContainers
块,然后是 containers
,最后是 volumes
块。查看下面正确的 yaml 文件:
