我试图启动并运行一个consul服务器群集。我有3个dockerized consul服务器正在运行，但我无法访问Web UI，HTTP API和DNS。
$ docker logs net-sci_discovery-service_consul_1

我无法通过HTTP API注册我的服务;上面显示的那些是在容器启动时使用配置脚本注册的。
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"

我对码头工人和领事都比较新。我已经浏览了网络，上面的选项是我对所需内容的理解。对前进方向的任何建议都会非常受欢迎。

更新docker-compose.yml以包含端口的长格式：
version: '3.2'
services:

hostname: "consul1"
ports:

- target: 8500
published: 8500

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:

答案 0 :(得分：0)
从Consul Web Gui page，确保您已使用-ui参数启动了代理。
UI位于与HTTP API相同的端口上的/ ui路径中 默认情况下，这是http://localhost:8500/ui
我确实看到8500在广播时映射到你的主机（0.0.0.0）。
同时检查（如this answer中所述）client_addr是否有帮助（至少用于测试）
