无法安装MySQL数据卷到Kubernetes Minikube吊舱
我试图通过Minikube与Kubernetesbuild立一个开发环境。 我使用Docker for Mac成功将相同的卷装载到相同的映像上，但我在Minikube上遇到了麻烦。
相关的文件和日志： db-pod.yml

我能够将数据目录从主机挂载到testing目录中的容器，但是我无法挂载到MySQL数据目录。 另外，我试图用适当的MySQL环境variables设置一个空目录到容器的数据目录，这在Docker for Mac中允许我在新目录中执行一个SQL转储，但是我在Minikube中看到了同样的错误。
任何可能的原因，或者如果我不build立我的开发环境首选Kubernetes / Minikube方式的想法，请分享您的想法。
我能够解决这个问题如下：
echo "/Users -network 192.168.99.0 -mask 255.255.255.0 -alldirs -maproot=root:wheel" | sudo tee -a /etc/exports sudo nfsd restart minikube start minikube ssh -- sudo umount /Users minikube ssh -- sudo /usr/local/etc/init.d/nfs-client start minikube ssh -- sudo mount 192.168.99.1:/Users /Users -o rw,async,noatime,rsize=32768,wsize=32768,proto=tcp
我在VirtualBox中运行Minikube。 我不知道这是否会与其他虚拟机驱动程序 – xhyve等。

编辑：我应该提到，这适用于minikube v0.14.0。
