이번에는 mysql과 wordpress pod을 만들어 연동시켜 서비스 하는 실습을 해보겠다.

 

Requirement

mysql, wordpress yml 파일 작성

- mysql

apiVersion: v1
kind: Pod
metadata:
  name: app-mysql
  labels:
    app: mysql

spec:
  containers:
  - name: mysql
    image: mysql:5.7
    imagePullPolicy: Never
    ports:
    - containerPort: 3306
    env:
    - name: MYSQL_ROOT_PASSWORD
      value: test1234!
    - name: MYSQL_DATABASE
      value: wordpress
    - name: MYSQL_ROOT_HOST
      value: "%"

 

- wordpress

apiVersion: v1
kind: Pod
metadata:
  name: word-rep
  labels:
    app: word

spec:
  containers:
  - name: word
    image: wordpress
    env:
    - name: WORDPRESS_DB_HOST
      value: 10.38.0.1:3306      # mysql이 설치된 워커 노드의 ip
    - name: WORDPRESS_DB_NAME
      value: wordpress
    - name: WORDPRESS_DB_USER
      value: root
    - name: WORDPRESS_DB_PASSWORD
      value: test1234!
    ports:
    - containerPort: 80

 

이제 wordpress을 외부로 노출시키면 된다.

kubectl expose pod word-rep --type=NodePort
