Can't figure out how to launch ovpn-admin after installing it using Docker

[arslaman]

I already had OpenVPN on my Ubuntu server and I decided to install the ovpn-admin using Docker but couldn't figure out how to launch the admin panel since bash said there's no file:

root@OpenVPN:~/ovpn-admin# ./ovpn-admin
-bash: ./ovpn-admin: No such file or directory

Here's a full log of installation and the attempt to launch it:
