macos。部署的docker_desktop。启用了自带这的k8s。 pod 怎么访问到宿主机的nfs

Answer 1

1.搭建NFS服务

安装NFS服务
yum install nfs-utils -y

创建共享目录
mkdir /usr/local/program/nfs/data -pv

编辑NFS的配置文件/etc/exports

将共享目录以读写权限暴露给某网段中的所有主机
/usr/local/program/nfs/data 172.22.4.0/24(rw,no_root_squash)

启动nfs服务
systemctl start nfs

2.使用

apiVersion: v1
kind: Pod
metadata:
  name: volume-nfs
  namespace: default
spec:
  containers:
  - name: nginx
    image: nginx
    ports:
    - containerPort: 80
    volumeMounts:
    - name: logs-volume
      mountPath: /var/log/nginx
  - name: tomcat-name
    image: tomcat
    command: ["/bin/sh","-c","tail -f /usr/local/tomcat/logs/access.log"]
    volumeMounts:
    - name: logs-volume
      mountPath: /usr/local/tomcat/logs
  volumes:
  - name: logs-volume
    nfs:
      server: 172.22.4.21  #nfs服务器地址
      path: /usr/local/program/nfs/data #共享文件路径   

3.创建Pod与验证

kubectl create -f volume-nfs.yaml

kubectl get pods volume-nfs

ls /usr/local/program/nfs/data/
