微服务注册发现集群搭建—单机版(Registrator+Consul+Consul-template+nginx)

1.创建模板文件 docker-compose.yml

#backend web application, scale this with docker-compose scale web=3
web:
  image: tomcat-fhm:1.0
  environment:
    SERVICE_8080_NAME: my-web-server
    SERVICE_TAGS: backend-1
    MY_HOST: host-1
  ports:
  - "8080"

#load balancer will automatically update the config using consul-template
lb:
  image: liberalman/nginx-consul-template:latest
  hostname: lb
  links:
  - consulserver:consul
  ports:
  - "80:80"

consulserver:
  image: progrium/consul:latest
  environment:
    SERVICE_TAGS: consul servers
  hostname: consulserver
  ports:
  - "8300"
  - "8400"
  - "8500:8500"
  - "53"
  command: -server -ui-dir /ui -data-dir /tmp/consul -bootstrap-expect 1

# listen on local docker sock to register the container with public ports to the consul service
registrator:
  image: gliderlabs/registrator:master
  hostname: registrator
  links:
  - consulserver:consul
  volumes:
  - "/var/run/docker.sock:/tmp/docker.sock"
  command: -internal consul://consul:8500

2.启动
docker-compose up
3.关闭
docker-compose down
4.后台运行
docker-compose up -d
5.说明
tomcat-fhm:1.0自己封装的项目镜像
