Proxmox Linux Container: Difference between revisions
imported>Altano Let's be more explicit about what the variables are for shell expansion. This example tripped me up by not working on zsh where the $BUILDID_ variable didn't expand correctly (since '_' was included in the name) |
Add note to only run /run/current-system/activate when no commands can be found, e.g. ls. |

= Building Proxmox Linux Containers with Nix = | |||
You can use 'make-system-tarball' to create a Linux Container that can run on Proxmox, for example like https://codeberg.org/raboof/nix-mastodon-bot/src/branch/main/default.nix#L31 | |||
= NixOS = | |||
With a small amount of work, it is possible to use NixOS as a LXC container under Proxmox. | With a small amount of work, it is possible to use NixOS as a LXC container under Proxmox. | ||
== Generate a container tarball == | |||
A better way to deploy a NixOS container tarball on Proxmox is described at [[Proxmox Virtual Environment#LXC]]. | |||

=== Black Console in Proxmox === | |||
The Proxmox console may appear black when launched. It is at the login prompt but no existing text is rendered. Just type "root" and hit enter and new text will get rendered just fine. If you are still unable to get the console to render, you can try changing the console to `/dev/console` instead of the standard tty. | |||
