Seems super interesting!
Thanks!
So I'm assuming this works by doing something like:
docker run -i -t -v /:/host yast-container
So that the yast-container can interact with the "root" filesystem from /?
Yes, that's the trick, it uses "-v /:/mnt". That's actually the same what YaST
does
during normal installation, in that case the target system is also mounted to
"/mnt".
To have full access to the host system it uses some more options, esp. the
"--privileged" is important. See
https://github.com/yast/yast-in-container/blob/9470635cfaae6b9e1729cb755a94479fc29e6e2b/src/scripts/yast2_container#L63-L66
For accessing the X session in the host it needs some extra options, see
https://github.com/yast/yast-in-container/blob/9470635cfaae6b9e1729cb755a94479fc29e6e2b/src/scripts/yast2_container#L47,
that might be useful if you want to run any X application in a container.
Today I found one more interesting use case: disaster recovery. First I removed
zypper + libzypp from the system and I was able to install it back using YaST
package manager in a container. Then I even removed rpm (!) itself and I was
still able to install it back to the system via the YaST container!
This is extremely cool. :D
I was also surprised from how bad situation I could easily recover... :-)
