How to ssh into a docker container?

Question

LXC

Hi all.
- installed the ssh service in the container
- forwarded the container port 22 to the host
- added permission to connect root to the container in the ssh_config of the container
- I try to connect remotely via ssh, after entering the password it says: permission deny ......
Tell me what could be the problem ? What else do you need to forward to the container besides the port to access it via ssh ?
Thanks

Answer 1

This task appeared in connection with the launch of gitlab in a docker container.
There were two solutions:

1. Allocate an additional IP address to the host, configure host ssh to the main ip, and give the additional one to gitlab services (ports 22, 443, 80)
   
2. the second option is to use ssh proxy. Like this . The point is that when connecting to the host machine under the credentials of a specific user (git), all traffic is directed to the container. All other users connect directly to the host machine and a shell is opened for them on it

Why do you need to go there via SSH?

After studying, I realized that the best solution is to use supervisor.
