端口转发到 docker 守护进程

Question

I have Ubuntu server & my laptop (another network). In my router settings I set port forwarding from my static external ip --> internal ubuntu server ip.

So, to connect to my server I just use ssh user@external_ip -p 21115 where 21115 binded in router settings. Now I run docker daemon at my server via dockerd -H 0.0.0.0:2375

What should I do to connect from my laptop to docker daemon?

Answer 1

Do the same thing as for server, but redirect different port on your router for this second connection.

for example:

"your external IP" and "dst port:2375" --> "your internal IP" and "dst port:2375".

I don't know what are possibilities of yours router, but to keep it safe you should add whitelist to allow this rules for trust IP only
