注意
- 服务编排里面启动参数那2个大括号跟jekyll语法冲突,具体编排见Github原文
- 因为2和3的agent配的
retry-join=consulserver1,所以consul-server1一定要先启动.然后再启动2和3,最后启动 client.
- consul-client用了阿里云的简单路由,所以直接拿容器的
8500端口来用就行.如果是其他方式的话,自己酌情配置
- 其他aliyun的标签就不说明了,跟主题无关.
- 最后我再补充一点,我这个配置是一个机器部署一个 agent, 最后挑第四台机作 client 的,没有那么多机器的,别问我怎么配.自己买机器去配就行了.
k8s
亲测把consul:1.2.3安装在了1.11.2的集群,具体见zeusro/deploy-consul-on-kubernetes
