docker无法进入容器内部

Question

docker进入容器一直失败，不知道啥原因，网上搜索了好多，也没解决，不知道有啥解决方法
kubectl exec -it kubernetes-dashboard-6bd77794f-ph2lr -n kubernetes-dashboard -- bin/bash
OCI runtime exec failed: exec failed: unable to start container process: exec: "bin/bash": stat bin/bash: no such file or directory: unknown
command terminated with exit code 126

Answer 1

先用docker inspect 容器ID看下支持的命令

看看是不是/bin/bash, 如果不是你就要换成/bin/sh
