1. Challenge

   Generate the Preseed File

   1. Configure LXD on the first host:

   lxd init
   

   Would you like to use LXD clustering? (yes/no) [default=no]:
   Do you want to configure a new storage pool? (yes/no) [default=yes]:
   Name of the new storage pool [default=default]:
   Name of the storage backend to use (btrfs, ceph, dir, lvm, zfs) [default=zfs]:
   Create a new ZFS pool? (yes/no) [default=yes]:
   Would you like to use an existing block device? (yes/no) [default=no]: yes
   Path to the existing block device: /dev/nvme1n1
   Would you like to connect to a MAAS server? (yes/no) [default=no]:
   Would you like to create a new local network bridge? (yes/no) [default=yes]:
   What should the new bridge be called? [default=lxdbr0]:
   What IPv4 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]:
   What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]:
   Would you like LXD to be available over the network? (yes/no) [default=no]: yes
   Address to bind LXD to (not including port) [default=all]:
   Port to bind LXD to [default=8443]:
   Trust password for new clients:
   Again:
   Would you like stale cached images to be updated automatically? (yes/no) [default=yes]
   Would you like a YAML "lxd init" preseed to be printed? (yes/no) [default=no]: yes
   

   2. Copy the provided preseed output and save it to a file in the home directory called preseed.yaml:

   vim preseed.yaml
   
   config:
     core.https_address: '[::]:8443'
     core.trust_password: pinehead
   networks:
   - config:
       ipv4.address: auto
       ipv6.address: auto
     description: ""
     managed: false
     name: lxdbr0
     type: ""
   storage_pools:
   - config:
       source: /dev/nvme1n1
     description: ""
     name: default
     driver: zfs
   profiles:
   - config: {}
     description: ""
     devices:
       eth0:
         name: eth0
         nictype: bridged
         parent: lxdbr0
         type: nic
       root:
         path: /
         pool: default
         type: disk
     name: default
   cluster: null
   

2. Challenge

   Configure the Second Server

   1. Copy over the preseed file:

   scp [email protected]:/home/cloud_user/preseed.yaml preseed.yaml
   

   2. Configure LXD:

   cat preseed.yaml | lxd init --preseed
   

3. Challenge

   Configure the Third Server

   Repeat the steps from the second server, or try with a single command:

   scp [email protected]:/home/cloud_user/preseed.yaml preseed.yaml | cat preseed.yaml | lxd init --preseed
