Discovery. Add other linux's containers to current environment.

[D Delmar Davis]

The magic of our current environment is largely handled by ubuntu's out of the box implementation of cloud.init, which through lxd profiles give us network configuration, security tweaks, and admin ssh key enabled user accounts.

Document at TaskCreatingNewContainers
When running up other distributions using lxd provided images everything hast to be redone manually.

• Goal: Is it possible to cleanly create LXD container images for other os's and use the same toolset?
• Secondary goal: Clean up profiles and documentation.

Specific targets i want to look at:

• Debian 9/10
• Centos 7
• Fedora 29
• openSUSE 15

debian 9

Have had success with Debian 9 except for the networking configuration. This required adding cloud init and utilities to the lxd provided debian image and adding templates and metatdata to it and republishing it. Since the network is initially set to redshirt in our environment this is really done. May revisit this once some of the RPM based OSs are up and running.

Image and profile is on bs2020 to test it

 lxc launch debian/9c -p susdev19 redshirt 

[D Delmar Davis]

actually fixed the networking as well.

Centos 7

Centos seems to have followed redhat down the no useful tools here path.
On top of cloud init and cloud utils, sudo, openssh-server, and the man pages were blatantly missing.
Once these were both installed the centos user was initially given password less cart blanch ala ubuntu ubuntu.
Which of course had to be fixed as well

# lxc launch centos/7c -p susdev19 redshirt
... or on kb2018 ...
# lxc launch bs2020:centos/7c -p bs2020:susdev19 redshirt

Also now our update.sh needs to be smarter enough to be apt agnostic.

Fedora 29

afik fedora is a heaping pile of shit.
I am moving on to suse

[D Delmar Davis]

This is worth continuing as part of Phase II.

• Centos and Debian are certainly good to go.
• Fedora and Suse have too much Sinatra in them to make the LXC provided images worth pursuing.

TODO:

Automate modifications to allow images to be updated easily.
