install ufw and openssh-server:

apt install ufw openssh-server -y

Make sure that the two services are up and running

# This is how to enable ssh 
sudo service ssh start  

# This will show you the status of the ssh
sudo service ssh status

# This how we check if it accessable from your host
ssh localhost 
# The authenticity of host 'localhost (127.0.0.1)' can't be established.
# ED25519 key fingerprint is SHA256:H+/SWyU8BgjbMDG13jc/na9TzbGxLLjaK0Sfop+LaUk.
# This key is not known by any other names
# Are you sure you want to continue connecting (yes/no/[fingerprint])? ^C

Check if the Accessable from docker network

from your Kali

# ssh from Kali
ssh 10.3.0.2

Now try to access that from your local machine

ssh localhost -p 2022
