K8S v1.20.6 容器之部署：RabbitMq3.9.11（单机）

---

只运行一个RabbitMq的Pod程序，本文采用 nfs 作为持久化储存。

拉取镜像并push到本地仓库

一个常用的轻量级镜像，只有几兆字节大小，常用于初始化任务
docker pull busybox
给镜像添加标签
docker tag busybox 10.200.40.39:8080/component/busybox
把镜像 push 到本地仓库
docker push 10.200.40.39:8080/component/busybox
节点拉取本地仓库的镜像
docker pull 10.200.40.39:8080/component/busybox

拉取镜像并push到本地仓库

docker pull rabbitmq:3.9.11-management
给镜像添加标签
docker tag rabbitmq:3.9.11-management 10.200.40.39:8080/component/rabbitmq:3.9.11-management
把镜像 push 到本地仓库
docker push 10.200.40.39:8080/component/rabbitmq:3.9.11-management
节点拉取本地仓库的镜像
docker pull 10.200.40.39:8080/component/rabbitmq:3.9.11-management

编写配置文件

文件（rabbitmq-service.yaml）如下：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-rabbitmq-deployment
  labels:
    app: my-rabbitmq

新建应用

kubectl apply -f rabbitmq-service.yaml

删除应用

kubectl delete -f rabbitmq-service.yaml

查看容器日志

kubectl describe pod my-rabbitmq-deployment
查看启动日志：
kubectl get pods（查看程序日志：kubectl logs <pod-name>）
kubectl logs my-rabbitmq-deployment-6fc788f4c8-rsrl2

进入容器应用内部

kubectl exec -it <pod-name> -- /bin/bash ，<pod-name> 由上一步命名执行得出

[root@k8smaster rabbitmq]# kubectl exec -it my-rabbitmq-deployment-??????? -- /bin/bash
[root@my-rabbitmq-deployment-76f6dcccd4-zv5sc /]# ls
anaconda-post.log  bin  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
