Incus preseed config

Help
1

Hello, I am trying to initialyse incus server with:

  virtualisation.incus = {
    enable = true;
    package = pkgs.incus;
    preseed = {

      config = {
        core.https_address = ":8443";
      };
    ......
  };

I cannot pass the config key/value. This config = { … }; does not work for me.
Ths for your help.

try "core.https_address" instead of core.https_address

3

thx but it didnt work…
I can create profiles, etc but when I try do put preseed.config it does work at all.
Did you try by yourself already? thx

4

can you please explain how things aren’t working? specific errors, etc…

Yes, thx! Here is my full code concerning incus in configuration.nix:

# incus !
  networking.nftables.enable = true;  
  virtualisation.incus = {
    enable = true;
    package = pkgs.incus;
    preseed = {
    
      #config = {
       # "core.https_address" = ":8443";
       # "backups.compression_algorithm" = "bzip2";
      #};
      
      profiles = [
        {
          
          devices = {
            root = {
    	      path = "/";
    	      pool = "default";
    	      type = "disk";
    	    };
          };
    	  name = "default";
        }
        {
          devices = {
            eth0 = {
              name = "eth0";
    	      parent = "bridge0";
    	      type = "nic";
    	      nictype = "bridged";
    	    };
          };
    	  name = "bridgeprofile";
    	  description = "merci Scott";
        }
      ];
      
      storage_pools = [
        {
          config = {
            source = "/dev/sdb1";
          };
          driver = "zfs";
          name = "default";
        }
      ];
        	
    };
  };

I want NixOS to initialize incus, so I do the following:
1/ sudo systemctl stop incus.service incus.socket incus-preseed.service
2/ sudo rm -r /var/lib/incus
3/ sudo fdisk /dev/sdb for creating empy and not formated partition /dev/sdb1
4/ edit /etc/nixos/configuration.nix
5/ sudo nixos-rebuild switch
6/ reboot

It works perfectly and silently with commented:

    #config = {
       # "core.https_address" = ":8443";
       # "backups.compression_algorithm" = "bzip2";
      #};

It creates the bridgeprofile, the zfs storage pool, etc.

But if uncomment, it does not work…silently. It does 1 to 6 but no profiles and storage pools are created.
Well I did some journalctl -r to see what it is happening, spending to much time on it…

OK it worked :smile:

config = {
      "core.https_address" = ":8443";
      "images.auto_update_interval" = 15;
      };

Before:

[alain@ALPHA:~]$ incus config show
config:
  core.https_address: :8443
  images.auto_update_interval: "18"

After (playing with incus-preseed.service:

[alain@ALPHA:~]$ sudo systemctl restart incus-preseed
Job for incus-preseed.service failed because the control process exited with error code.
See "systemctl status incus-preseed.service" and "journalctl -xeu incus-preseed.service" for details.

[alain@ALPHA:~]$ incus config show
config:
  core.https_address: :8443
  images.auto_update_interval: "15"

So 15 intead of 18.

And you were right putting the cotes solved it. Key/value: and Key must be string here, a little bit tricky…
Thx a lot
