Kuberenetes部署失败

Question

Kubernetes部署失败。谁能告诉我哪里出了问题?

我的观察:当我删除卷挂载的东西，服务反弹

volumeMounts:
- name: my-volume
mountPath: /app
volumes:
- name: my-volume
hostPath:
path: /tmp/vpath 

删除上面的代码

State:          Waiting
Reason:       CrashLoopBackOff
Last State:     Terminated
Reason:       ContainerCannotRun
Message:      OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "./main": stat ./main: no such file or directory: unknown

这是我的部署文件

谁能告诉我为什么卷挂载会导致这个失败

Answer 1

我想你可能是在DockerfileWORKDIR上挂载卷，因此您正在覆盖它正在查找的文件并抛出此错误:"…/main: no such file or directory:".

如果是这个问题，更新docker的WORKDIR或挂载路径。如果这不是问题，请包含Dockerfile。
