我已经尝试设置 consul 服务器并将代理连接到它 2 或 3 天了。我正在使用 docker-compose。
但是在执行加入操作后，代理会收到一条消息“代理不存在或无法访问”。
以下是日志：

我的设置是： docker-compose 服务器：
consul1:
image: "consul.1.0.1"
container_name: "consul1"
hostname: "consul1"
volumes:
- ./consul/config:/config/
ports:
- "8400:8400"
- "8500:8500"
- "8600:53"
- "8300:8300"
- "8301:8301"
command: "agent -config-dir=/config -ui -server -bootstrap-expect 1"
请帮忙解决问题。
我认为你使用了错误的领事服务器IP地址
10.1.30.91 这不是 docker 容器 IP，它可能是您的主机地址/virtualbox。
获取 consul-container ip 并使用它加入 consul-agent 命令。

尝试通过执行以下命令获取正确的IP地址：
docker inspect <container id> | grep "IPAddress"
其中 是 consul 服务器的容器 ID。
不要在命令中使用获取的地址代替“10.1.30.91”
consul agent -join <IP ADDRESS CONSUL SERVER> -data-dir=/tmp/consul
