⁠Build image

⁠Command line

:computer: docker pull marchandd/term_ssh_user_monodotnet45

⁠Firewall

:warning: If your Firewall is enabled on the host, with default outgoing policy turned to deny, you will have to disable 22 port filtering:

• Make a new rule for OpenSSH (22/TCP) to enable outgoing policy.

⁠Build container (standalone mode only)

Not necessary to do if you want only to run MonoDevelop image...
Standalone mode only if you want to do software install by yourself.

⁠Command line

:computer: docker run -d -p XXX.XXX.XXX.XXX:YYYYY:22 --name latest_term_ssh_user_monodotnet45 marchandd/term_ssh_user_monodotnet45

Where XXX.XXX.XXX.XXX is your IP v4 address.
Where YYYYY is your Private port, if you doesn't know free port, try from 49200...
