k8s学习七:使用本地docker镜像仓库部署服务

在master节点中,通过docker 启动docker 仓库服务:

docker run -d -p 5000:5000 --restart=always --name registry registry:2

没有此镜像会自动下载

更新所有节点的仓库地址

所有的节点都更新/etc/docker/daemon.json,insecure-registries为本地仓库地址。这里我填的本地仓库地址为master节点的ip。

重启所有节点的docker

root@master:/home/tioncico# systemctl daemon-reload
root@master:/home/tioncico# systemctl restart docker

打包镜像推送到本地节点

docker tag tioncico/go:v1.0.1  192.168.192.9:5000/tioncico/go:v1.0.1  //原有教程有build,这里直接打一个新的tag
docker push 192.168.192.9:5000/tioncico/go:v1.0.1

部署go的yaml文件修改

主要是指定image的地址:

\-\-\-
apiVersion: apps/v1
kind: Deployment
metadata:
  name: go-deployment
  labels:
    app: go
spec:
  selector:
    matchLabels:
      app: go
  replicas: 3
  minReadySeconds: 5
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  template:
    metadata:
      labels:
        app: go
    spec:
      containers:
        - image: 192.168.192.9:5000/tioncico/go:v1.0.1
          name: go
          imagePullPolicy: Always
          command: ["./main","-v","v1.0.1"]
          ports:
            - containerPort: 8080
              protocol: TCP
\-\-\-
apiVersion: v1
kind: Service
metadata:
  name: go-service
  labels:
    app: go
spec:
  selector:
    app: go
  ports:
    - name: go-port
      protocol: TCP
      port: 8080
      targetPort: 8080
      nodePort: 30080
  type: NodePort

然后部署即可
