Question

我尝试在Mac转发8500端口上运行Consul image进行简单测试。我运行图像的命令是：

docker run -it -p 8500：8500 consul agent -server -bootstrap 0.0.0.0

我不使用--net=host因为它在Mac上不起作用所以我尝试转发8500.

当我尝试从我的Mac远程登录时，连接立即关闭：

user$ telnet localhost 8500
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

或者当我尝试添加新值时，我得到：

consul kv put foo bar
Error! Failed writing data: Put http://127.0.0.1:8500/v1/kv/foo: dial tcp 127.0.0.1:8500: getsockopt: connection refused

我错过了什么？

我刚试过你发布的内容，似乎端口8500已经打开

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                                                      NAMES
f4ac8a5233e2        consul              "docker-entrypoint..."   2 minutes ago       Up 2 minutes        8300-8302/tcp, 8301-8302/udp, 8600/tcp, 8600/udp, 0.0.0.0:8500->8500/tcp   sharp_knuth

我明白了：

Trying 0.0.0.0...
Connected to dev-consul
Escape character is '^]'.
Connection closed by foreign host.

但是，它正在运行，您可以从日志中看到：

为什么我不能使用consul图像在主机上转发端口8500？
