Note: I am just beginning to learn the ins & outs of LXC containers.
So far, LXC containers are just like regular Linux (for the most part...) & the same procedures apply when building.
Building a Container
Templates
LXC Containers start with a template.
For our example here, we're going to start with a basic Debian 11 template.
This means we need to ensure we have the template on the PVE host.
- Sign into the PVE UI & select your Local datastore
- Select the CT Templates storage
- Click the Templates button
- Select a template package (we're going with debian-11-standard) then hit the Download button
Creating the Container
Now that you have a template to start from, you can hit the Create CT button.
For now, we'll create a very basic container.
- 1st screen: choose an ID# and a hostname for the container. Then enter the password for root on this container (twice...). Then hit Next
- 2nd screen: select the template we downloaded above. Then hit Next
- 3rd screen: choose a storage location & boot disk size. Then hit Next
- 4th screen: how many CPU cores you want available to the container. Then hit Next
- 5th screen: how much memory you want available to the container. Then hit Next
- 6th screen: set up networking (you'll note it defaults to static addressing... silly...) Then hit Next
- 7th screen: set up DNS (Why in heck this isn't considered part of networking...) Then hit Next
- 8th (final) screen: Look things over to make sure they're the way you want them. Possibly check the Start after created box. Then hit Finish
Configuring & Using the Container
Congratulations!
You have an LXC container.
At this point,, for all intents and purposes, it works just like a normal Linux VM.
There will be minor oddities, but basically, it's a lightweight VM.
Stumbling Blocks
Standard LXC containers built upon Debian seem to block non-root users from using ping...
ping: socket: Operation not permitted
Solution #3 seems most appropriate...
sudo chmod u+s /usr/bin/ping
