[Seaside] Ci automated deploy of seaside to Digital Ocean

[Tim Mackinnon]

Ah - I see (hadn’t thought about having a configurable port number),

So if Ive understood correctly I could install supervisord with a config file like yours.

Then on completion of my build, I could sftp my new image up to DO, and then execute a command like: supervisorctl restart psworker?

Doing a check does seem to show lots of people use either it or monit (the latter being a bit more complicated).

Thanks for the help - this is my next learning step.
