在安装 hostPath 类型的卷时,kubernetes docs为每个操作系统和每个驱动程序提供名称VM。
然而,缺少这种情况:
这是我想要使用的目标部署,以避免在每次更改代码后重新创建图像。
这仅适用于开发环境。在生产环境中,代码将直接在图像中。

基于此doc,尚未在KVM驱动程序中实现主机文件夹共享。这是我实际使用的驱动程序。
为了克服这个问题,有两种解决方案:
使用 virtualbox 驱动程序,以便通过将localhost /home/THE_USR/...
上的路径更改为/hosthome/THE_USR/...
根据命令$ minikube mount /home/THE_USR/...
将卷装入minikube VM。该命令将返回minikube VM上已安装卷的路径。示例给出了。
(a)在minikube VM上安装卷
minikube mount
命令返回路径/ mount-9p
$ minikube mount -v 3 /home/amine/DockerProjects/gcloud-kubernetes/application/06-hostPath-volume-example-minikube
Mounting /home/amine/DockerProjects/gcloud-kubernetes/application/06-hostPath-volume-example-minikube into /mount-9p on the minikubeVM
This daemon process needs to stay alive for the mount to still be accessible...

(b)部署路径的规范

volumeMounts:

mountPath: /var/www/html
volumes:
- name: vol-php-hostpath
hostPath:
path: /mount-9p
(c)检查安装音量是否正常工作
amine@amine-Inspiron-N5110:~/DockerProjects/gcloud-kubernetes/application/06-hostPath-volume-example-minikube$ kubectl exec -ti php-hostpath-3498998593-6mxsn bash
root@php-hostpath-3498998593-6mxsn:/var/www/html# cat index.php
<?php
echo "This is my first docker project";
root@php-hostpath-3498998593-6mxsn:/var/www/html# cat index.php
<?php
echo 'This is my first hostPath on kubernetes';
root@php-hostpath-3498998593-6mxsn:/var/www/html# cat index.php
<?php
echo 'This is my first hostPath on kubernetes';
root@php-hostpath-3498998593-6mxsn:/var/www/html#
NB:这种卷安装只是开发环境。如果我在生产环境中,则不会安装代码:它将在图像中。
希望它可以帮助他人。
