无法连接到 mysql 服务器 docker 容器在 Docker 操场上运行

Question

I'm running an out of the box mysql docker container inside docker play ground at https://labs.play-with-docker.com/

[node1] (local) root@192.168.0.8 ~
$ docker ps
CONTAINER ID   IMAGE     COMMAND                  CREATED       STATUS       PORTS                               NAMES
f0f8ae352373   mysql     "docker-entrypoint.s…"   2 hours ago   Up 2 hours   0.0.0.0:3306->3306/tcp, 33060/tcp   memories
[node1] (local) root@192.168.0.8 ~
$ 

现在，如果我必须从我的本地计算机连接到这个 mysql 实例，建议创建一个 SSH 隧道。

这是我尝试过的

➜  sqlconnect ✗ ssh -L 3306:192.168.0.8:3306 ip172-18-0-115-c1mf4d0h550g00dlq95g@direct.labs.play-with-docker.com

当我尝试从我的 sql dbeaver 客户端连接时

这是我得到的错误

[node1] (local) root@192.168.0.8 ~
$ channel 3: open failed: administratively prohibited: open failed

你不能这样做。 它被设计禁用。 检查https://github.com/play-with-docker/play-with-docker/issues/373#issuecomment-814553922

如果环境中已经有终端，为什么要从 PC 连接？
