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

Discussion & a solution

Solution #3 seems most appropriate...

  • sudo chmod u+s /usr/bin/ping
