本篇内容介绍了“Traefik怎么使用”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
traefik是一个使你把微服务暴露出来变的更容易的http反向代理和负载均衡软件。traefik支持K8S、docker swarm、mesos、consul、etcd、zookeeper等基础设施组件,个人认为更适合容器化的微服务,traefik的配置会自动的、动态的配置更新自己。
本篇主要模拟的是traefik+docker swarm mode的场景,由traefik自动发现swarm mode下的service
ubuntu16.04-1 | swarm manager | traefik |
ubuntu16.04-2 | swarm works | |
ubuntu16.04-3 | swarm works |
ps:还是之前文章做实验的swarm集群

ps:把下载完的traefik_linux-amd64二进制文件重命名成traefik,上传到镜像制作服务器。
