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了答案，并以--mount-string开头分享。
--mount-string当我检查给定Minikube的泊坞窗时，它返回
$ minikube start --mount-string="$HOME/.ssh/:/ssh-directory" --mount

💡 You can also use 'minikube kubectl -- get pods' to invoke a matching version
并检查$ docker ps

的内容时。
它出现IO错误。
/ssh-directory我知道Minikube有默认的安装点。如$ docker exec -it 5ad64f642b63 ls /ssh-directory
ls: cannot access '/ssh-directory': Input/output error
中所述，

，并将它的brew install minikube设置为driver。
docker安装点中没有$ cat ~/.minikube/config/config.json
{
"driver": "docker"
}
驱动程序的映射。
最初，此目录包含文件，但是以某种方式，当我尝试创建Pod时，它会删除或出现错误。
虽然在ubuntu上复制此文件，但遇到了确切的问题。
该目录确实看起来好像已挂载，但是缺少文件，这使我认为这是使用docker驱动程序挂载目录的普遍问题。
github上存在关于同一问题（docker）的公开问题，并且公开了功能请求mount directory empty。
检查minikube容器没有显示该已安装卷的记录，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to mount host volumes into docker driver已安装到minikube的/var/lib/docker/volumes/minikube/_data目录中）。
/var作为解决方法，您可以使用以下命令将$ docker inspect minikube
"Mounts": [
{
"Type": "volume",
"Name": "minikube",
"Source": "/var/lib/docker/volumes/minikube/_data",
"Destination": "/var",
"Driver": "local",
"Mode": "z",
"RW": true,
"Propagation": ""
}
目录复制到正在运行的minikube docker容器中：
.ssh然后将该所需目录安装到窗格中。
