k8s配置文件方式部署pod

1. 配置文件方式部署pod

1.1 生成yaml文件

# 1.项目尝试启动，生成项目启动yaml文件
kubectl create deployment springboot-k8s --image=38-springboot-k8s-1.0.0-jar --dry-run -o yaml > deploy.yaml

 

1.2 修改yaml文件，配置从本地拉取镜像

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: hellok8s
  name: hellok8s
spec:
  replicas: 1
  selector:
    matchLabels:
      app: hellok8s
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: hellok8s
    spec:
      containers:
      - image: hellok8s
        name: hellok8s
        imagePullPolicy: Never  #从本地拉取镜像
        resources: {}
status: {}

 

1.3 执行命令，解析文件

kubectl apply -f boot-deploy.yaml  (yaml是资源清单)

 

1.4 暴露pods端口

kubectl expose deployment springboot-k8s --port=8080 --type=NodePort

 

1.5 查看服务暴露端口

kubectl get services
