挂载类型为 hostPath 的卷时,kubernetes docs为每个操作系统和每个驱动程序提供名称VM。
但是,缺少这种情况:
这是我要使用的目标部署,以避免在每次更改代码后重新创建镜像。
这仅用于开发环境。在生产环境中,代码将直接显示在图像中。
apiVersion: extensions/v1beta1
kind: Deployment

谢谢...
最佳答案
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:
/home/THE_USR/...
上的路径更改为/hosthome/THE_USR/...
$ minikube mount /home/THE_USR/...
将卷安装到minikube VM。该命令将为您返回minikube VM上已安装卷的路径。例子已经给出。 例
(a)在minikube VM上安装卷
minikube mount
命令返回该路径/ 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)部署上的路径规范

kind: Deployment
metadata:
name: php-hostpath
spec:
replicas: 1

labels:
app: php-hostpath
spec:
containers:
- name: php-hostpath

volumeMounts:
- name: vol-php-hostpath
mountPath: /var/www/html
volumes:
- name: vol-php-hostpath
hostPath:
path: /mount-9p
(c)检查安装卷是否工作良好
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#
注意:这种卷安装只是开发环境。如果我在生产环境中,则不会挂载代码:它将在镜像中。
希望它能帮助别人。
