How to upgrade Docker from SSH

My website suddenly have issue with connectivity. I think it’s docker related and I want to know what command I need to use to upgrade it.


I updated discourse but get ssl issues. Tried renew letsencrypt, in the logs I see

“The NOTIFY_HOOK is empty, just return.”

I run git pull and I get:

"Unable to access ‘’: Could not resolve host:

I tried to upgrade docker and the command doesn’t do anything:

“wget -qO- | sh”

I don’t know what to do, many issues and site is down because of that.
