docker - 来自服务器的领事空回复

Question

我正在尝试启动并运行领事服务器群集。我有3个正在运行的dockerized领事服务器，但是无法访问Web UI，HTTP API或DNS。

$ docker logs net-sci_discovery-service_consul_1
==> WARNING: Expect Mode enabled, expecting 3 servers
==> Starting Consul agent...
==> Consul agent running!
           Version: 'v0.8.5'
           Node ID: 'ccd38897-6047-f8b6-be1c-2aa0022a1483'
         Node name: 'consul1'

      Cluster Addr: 172.20.0.2 (LAN: 8301, WAN: 8302)
    Gossip encrypt: false, RPC-TLS: false, TLS-Incoming: false

我也无法通过HTTP API注册服务。容器启动时，上面显示的内容使用配置脚本注册。

这是我的 docker-compose.yml:

version: '2'
services:
  consul1:
    image: "consul:latest"
    container_name: "net-sci_discovery-service_consul_1"
    hostname: "consul1"
    ports:
      - "8400:8400"
      - "8500:8500"
      - "8600:8600"
    volumes:
      - ./etc/consul.d:/etc/consul.d
    command: "agent -server -ui -bootstrap-expect 3 -config-dir=/etc/consul.d -bind=0.0.0.0"
  consul2:
    image: "consul:latest"
    container_name: "net-sci_discovery-service_consul_2"
    hostname: "consul2"
    command: "agent -server -join=consul1"
    links:
      - "consul1"
  consul3:
    image: "consul:latest"
    container_name: "net-sci_discovery-service_consul_3"
    hostname: "consul3"
    command: "agent -server -join=consul1"
    links:
      - "consul1"

我对docker和consul都比较陌生。我在网上浏览了一下，上面的选项是我对要求的理解。任何关于前进道路的建议都将受到欢迎。

编辑:

更新了 docker-compose.yml以包括端口的长格式:

version: '3.2'
services:
  consul1:
    image: "consul:latest"
    container_name: "net-sci_discovery-service_consul_1"
    hostname: "consul1"
    ports:
      - target: 8400
        published: 8400
        mode: host
      - target: 8500
        published: 8500
        mode: host
      - target: 8600
        published: 8600
        mode: host
    volumes:
      - ./etc/consul.d:/etc/consul.d
    command: "agent -server -ui -bootstrap-expect 3 -config-dir=/etc/consul.d -bind=0.0.0.0 -client=127.0.0.1"
  consul2:
    image: "consul:latest"
    container_name: "net-sci_discovery-service_consul_2"
    hostname: "consul2"
    command: "agent -server -join=consul1"
    links:
      - "consul1"
  consul3:
    image: "consul:latest"
    container_name: "net-sci_discovery-service_consul_3"
    hostname: "consul3"
    command: "agent -server -join=consul1"
    links:

Answer 1

确保从Consul Web Gui page启动了带有-ui参数的代理。

The UI is available at the /ui path on the same port as the HTTP API.
By default this is http://localhost:8500/ui

我确实在广播(0.0.0.0)上看到8500映射到您的主机。

还要检查 this answer是否可以(至少在测试中)(如 client_addr 一样)
