《K8s 入门三 》快速部署一个网站

1. 部署应用流程

制作镜像[dockerfile] –> 使用控制器部署镜像[deployment] –>对外暴露应用[service] –>日常运维

2. 获取nginx 镜像

#docker pull nginx
#docker images
REPOSITORY                                                        TAG       IMAGE ID       CREATED        SIZE
nginx                                                             latest    87a94228f133   2 weeks ago    133MB

3.使用控制器部署镜像

 #kubectl create deployment nginx --image=nginx --replicas=3 
 deployment.apps/nginx created

#  kubectl get deploy,pods
NAME                    READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/nginx   3/3     3            3           2m55s

NAME                         READY   STATUS    RESTARTS   AGE
pod/nginx-6799fc88d8-2qwfq   1/1     Running   0          2m55s
pod/nginx-6799fc88d8-72wkn   1/1     Running   0          2m55s
pod/nginx-6799fc88d8-vqkhw   1/1     Running   0          2m55s

4.创建一个service 将应用暴露到外网

 # kubectl expose deployment.apps/nginx --port=80 --target-port=80 --type=NodePort
service/nginx exposed
# kubectl get service
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP   10.1.0.1     <none>        443/TCP        27h
nginx        NodePort    10.1.28.92   <none>        80:31162/TCP   23s

5.验证 http://47.89.217.69:31162/
