我必须将本地.ssh目录内容共享到pod。我搜索帽子，并从其中一个帖子中得到答案，以--mount-string开头分享。
$ minikube start --mount-string="$HOME/.ssh/:/ssh-directory" --mount

❗ /usr/local/bin/kubectl is v1.15.5, which may be incompatible with Kubernetes v1.18.0.
💡 You can also use 'minikube kubectl -- get pods' to invoke a matching version
当我检查给定Minikube的docker时，它会返回
$ docker ps

并检查.ssh目录内容是否存在。
$ docker exec -it 5ad64f642b63 ls /ssh-directory

我已将yml部署为

当我在docker中检查/ssh-directory的内容时。
它给出IO错误。

我知道Minikube有默认的挂载点。如中所述https://minikube.sigs.k8s.io/docs/handbook/mount/，

但我安装了minikube作为brew install minikube，并将其设置为driver作为docker。
$ cat ~/.minikube/config/config.json
{
"driver": "docker"
}
装载点中没有docker驱动程序的映射。
最初，这个目录有文件，但不知何故，当我试图创建pod时，它删除了或出现了问题。
在ubuntu上复制时，我遇到了确切的问题。
目录看起来确实像是挂载的，但文件丢失了，这让我认为这是使用docker驱动程序挂载目录的常见问题。
github上存在关于相同问题的公开问题(装载目录为空(，以及将主机卷装载到docker驱动程序中的公开功能请求。
检查minikube容器不会显示已安装卷的记录，并确认github请求中提到的信息，即到目前为止，与主机共享的唯一卷是默认安装的卷(即安装到minikube的/var目录中的/var/lib/docker/volumes/minikube/_data(。
$ docker inspect minikube
"Mounts": [
{
"Type": "volume",
"Name": "minikube",
"Source": "/var/lib/docker/volumes/minikube/_data",
"Destination": "/var",
"Driver": "local",
"Mode": "z",
"RW": true,
"Propagation": ""
}
作为解决方法，您可以使用以下命令将.ssh目录复制到正在运行的minikube docker容器中：
docker cp $HOME/.ssh minikube:<DESIRED_DIRECTORY>
然后将这个所需的目录装载到pod中。
