서비스를 외부로 노출하기 ( wordpress - mysql )

 

시크릿 생성

pv ( mysql, wordpress ) 생성

pvc ( mysql, wordpress ) 생성

mysql ,wordpress deployment 생성

mysql ,wordpress service 생성

순으로 진행된다. 

 

namespace는 test라는것을 만들어서 진행했다. 

 

 

 

먼저 시크릿

 

 

 

password를 설정하기전에 자신의 password암호화를 한다. 

 

아래처럼 입력하면 원하는 password의 암호화된 것을 얻을 수 있는데, 

echo -n <password> | base64

저걸로 아래에 넣어준다. 

 

#secret-mysql.yaml

apiVersion: v1
kind: Secret
metadata:
  name: mysql-root
type: Opaque
data:
  password: <secret password>

 

 

 

그리고 pv를 생성한다. 

#pv-mysql.yaml

kind: PersistentVolume
apiVersion: v1
metadata:
  namespace: test
  name: pv0001
  labels:
    type: local
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/wordpress-server/mysql"

 

#pv-wordpress.yaml

kind: PersistentVolume
apiVersion: v1
metadata:
  namespace: test
  name: pv0002
  labels:
    type: local
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/wordpress-server/wordpress"

 

pvc파일 

#pvc-mysql.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  namespace: test
  name: mysql-v
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

#pvc-wordpress.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  namespace: test
  name: wordpress-v
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

 

mysql deployment

#mysql.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: test
  name: mysql
  labels:
    app: mysql
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
        - image: mysql:5.6
          name: mysql
          env:
            - name: MYSQL_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql-root
                  key: password
            - name: MYSQL_DATABASE
              value: k8sdb
            - name: MYSQL_USER
              value: k8suser
            - name: MYSQL_ROOT_HOST
              value: '%'
            - name: MYSQL_PASSWORD
              value: admin
          ports:
            - containerPort: 3306
              name: mysql
          volumeMounts:
            - name: mysql-v
              mountPath: /var/lib/mysql
      volumes:
        - name: mysql-v
          persistentVolumeClaim:
            claimName: mysql-v

 

mysql service

#mysql-service.yaml 
apiVersion: v1
kind: Service
metadata:
  namespace: test
  name: mysql
  labels:
    app: mysql
spec:
  type: ClusterIP
  ports:
    - port: 3306
  selector:
    app: mysql

 

 

mysql service를 배포했으면, clusterip를 긁어서 

wordpress deployment에 넣어준다. 

#wordpress.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: test
  name: wordpress
  labels:
    app: wordpress
spec:
  replicas: 1
  selector:
    matchLabels:
      app: wordpress
  template:
    metadata:
      labels:
        app: wordpress
    spec:
      containers:
        - image: wordpress:4.8-apache
          name: wordpress
          env:
          - name: WORDPRESS_DB_HOST
            value: <mysql_service_port>:3306
          - name: WORDPRESS_DB_NAME
            value: k8sdb
          - name: WORDPRESS_DB_USER
            value: k8suser
          - name: WORDPRESS_DB_PASSWORD
            valueFrom:
              secretKeyRef:
                name: mysql-root
                key: password
          ports:
            - containerPort: 80
              name: wordpress
          volumeMounts:
            - name: wordpress-v
              mountPath: /var/www/html
      volumes:
        - name: wordpress-v
          persistentVolumeClaim:
            claimName: wordpress-v

 

#wordpress-service.yaml

apiVersion: v1
kind: Service
metadata:
  namespace: test
  labels:
    app: wordpress
  name: wordpress
spec:
  type: NodePort
  ports:
    - nodePort: 31000
      port: 80
      targetPort: 80
      protocol: TCP
  selector:
    app: wordpress

 

 

이렇게 해주고 master node의 ip에 nodeport를 붙여주면 접속이 된다. 

 

 

 

 

 

 

NFS 볼륨 사용

node1에 

 

 

node2,3에는

 

mount -t nfs 192.168.108.22:/nfs-server ./nfs-server

 

 

 

 

 

pv.yaml

 

pvc.yaml

mysql.yaml

 

 

걍 mysql은 아래처럼 만들기
