kubeneters上部署mysql

一、编写 Namespace，mysql_ns.yaml 文件

[root@k8s-master01 ~]# mkdir  mysql
[root@k8s-master01 ~]# cd mysql
[root@k8s-master01 mysql]#  vim  mysql_ns.yaml

apiVersion: v1
kind: Namespace
metadata:
  name: mysql

:wq保存

二、编写 PersistentVolume、PersistentVolumeClaim，mysql_pvc.yaml 文件

[root@k8s-master01 ~]# cd mysql
[root@k8s-master01 mysql]#  vim  mysql_pvc.yaml 

---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-pv
  namespace: mysql
  labels:
    app: mysql
spec:
  storageClassName: local-storage
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  nfs:
    server: 192.168.3.20
    path: /data/nfs/prometheus
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: Exists
  persistentVolumeReclaimPolicy: Retain
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
  namespace: mysql
spec:
  storageClassName: local-storage
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

三、编写 Service，mysql_svc.yaml 文件

[root@k8s-master01 ~]# cd mysql
[root@k8s-master01 mysql]#  vim  mysql_svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: mysql
  namespace: mysql
  labels:
    app: mysql
spec:
  selector:

  clusterIP: ""
  ports:
    - port: 3306
      protocol: TCP
      targetPort: 3306



:wq保存

四、编写 Deployment，mysql_deploy.yaml 文件

[root@k8s-master01 ~]# cd mysql
[root@k8s-master01 mysql]#  vim  mysql_deploy.yaml
apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
  name: mysql
  namespace: mysql
  labels: 
    app: mysql
spec:
  selector:
    matchLabels:
      app: mysql
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:

          env:
            - name: MYSQL_ROOT_PASSWORD
              value: password
          ports:
            - containerPort: 3306
              name: mysql
          volumeMounts:
            - name: mysql-persistent-storage
              mountPath: /var/lib/mysql
      volumes:
        - name: mysql-persistent-storage
          nfs:
            server: 192.168.3.20
            path: /data/nfs/mysql 



:wq保存

五、运行.yaml 文件

[root@k8s-master01 ~]# cd mysql
[root@k8s-master01 mysql]#  kubectl apply -f mysql_ns.yaml
[root@k8s-master01 mysql]#  kubectl apply -f mysql_cm.yaml
[root@k8s-master01 mysql]#  kubectl apply -f mysql_pvc.yaml
[root@k8s-master01 mysql]#  kubectl apply -f mysql_rbac.yaml
[root@k8s-master01 mysql]#  kubectl apply -f mysql_svc.yaml
[root@k8s-master01 mysql]#  kubectl apply -f mysql_deploy.yaml
