Two-container and authorized_keys?

Installation
1

In the end of web_only.yml is this line:

awk -F\# '{print $1;}' ~/.ssh/authorized_keys | awk 'BEGIN { print "Authorized SSH keys for this container:"; } NF>=2 {print $NF;}'

What is the meaning of it? I’m just wondering because I’ve never created any SSH-keys (and won’t until I have to rsync something between two VPS).

I get this:

cannot open file '/root/.ssh/authorized_keys' for reading: No such file or directory

That is a legit notice, because I don’t have that. But should I have? And if yes, how would ”SSH key for a container” differ from a server? Should I then treat that container as a independent server, create normally there SSH-key and use those normal way as one do between two servers?

Everything works just fine, though. But that bugs me because I don’t understand :joy:

You can delete that line. A long time ago it was convenient or required to ssh into a container instead of doing docker exec or launcher enter. I’ve never done it or seen anyone do it.
