Kubernetes各组件YAML语法

Nginx为例

1.创建NFS共享目录

[ root@localhost ~ ]# yum -y install nfs-utils rpcbind

[ root@localhost ~ ]# mkdir -p /nfsdata

[ root@localhost ~ ]# echo "/nfsdata 192.168.3.0/24(rw,no_passwd_squash,sync)" >> /etc/export

[ root@localhost ~ ]# systemctl enable rpcbind nfs

#开启ipv6

[ root@localhost ~ ]# vim /etc/sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0
net.ipv6.conf.lo.disable_ipv6 = 0

[ root@localhost ~ ]# sysctl -p

[ root@localhost ~ ]# systemctl start rpcbind nfs

[ root@localhost ~ ]# showmount -e localhost

2.创建PV

[ root@localhost ~ ]# vim nginx.pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nginx
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteMany
  persistentVolumeReclaimPolicy: Recycle
  storageClassName: nfs
  nfs:
    path: /nfsdata
    server: 192.168.3.2

3.创建PVC

[ root@localhost ~ ]# vim nginx.pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nginx
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi
  storageClassName: nfs

4.创建Deployment

[ root@localhost ~ ]# vim nginx.deployment.yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  replicas: 2
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      name: nginx
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: ntp.wei.club/nginx/nginx:latest
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: /usr/share/nginx/html
          subPath: nginx
          name: storage
      volumes:
      - name: storage
        persistentVolumeClaim:
          claimName: nginx
    

5.创建Service

[ root@localhost ~ ]# vim nginx.service.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx
  labels:
    app: nginx
spec:
  selector:
    app: nginx
  type: NodePort
  ports:
    - nodePort: 8080
      name: web
      port: 80
      targetPort: 80
