Docker(二十) consul 在公有云1分钟部署（腾讯云）

其实很简单利用helm 直接安装

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

helm install --name consul --namespace=consul stable/consul

然后等一分钟就安装好了

web管理界面可以通过svc 对外的8500端口来访问

另外写下之间手动写的编排文件

这里有个问题，因为consul是有状态服务，所有必须用pvc 来进行存储，我这里为了方便，直接挂在了hostpath，后续更新storageclass的方式
