k8s一个pod运行多个container和相关命令

apiVersion: apps/v1
kind: Deployment   # 定义是Deployment
metadata:
  name: tomcat01
spec:
  selector :
    matchLabels:
      app: tomcat01
  replicas: 1
  template:
    metadata:
      labels:
        app: tomcat01
    spec:
      containers:
      - name: tomcat01
        image: tomcat
        ports:
        - containerPort: 8080
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80
        command: ["sh","-c","sleep 1000"]

进入指定容器要使用-c命令

kubectl exec -it tomcat01-79f6b6cc97-6zrbb -c nginx /bin/bash
