docker allows host ssh to connect to the docker container

In the docker container, install ssh:

1) Replace the installation source in the container with 163 source

2) Install ssh services

apt-get update 
apt-get install openssh-server 

3) Add directory and modify ssh configuration file

mkdir -p /var/run/sshd 
 
vim /etc/pam.d/sshd  

Find the line session required pam_loginuid.so and comment it out

4) Add the host public key to be linked to

Put the public key in /root/.ssh /authorized_key

The next step is to start the container on the host, allocate the port, and enable THE ssh service:

docker run -p 10022:22 -d sshd:ubuntu /usr/sbin/sshd -D 

Try the link:

ssh 192.168.163.131 -p 10022 

ip is the host for the container, ip
