Collection of scripts to manage Proxmox environments.
Please read section Using Docker on LXC if you are planning to use Docker with Linux Containers (LXC).
To migrate an existing Windows VM from Hyper-V to Proxmox see this other project (for Windows) first.
To download all scripts into a temporary folder:
source <(curl -Ls https://bit.ly/p-v-a)This will download and execute bootstrap.sh. It will also install unzip apt package.
Usage: ./download-cloud-image.sh <url> [OPTIONS]
<url> Url of image to download.
--no-clobber, -nc Doesn't overwrite an existing image.
--help, -h Display this help message.
Downloads an image from given url into /var/lib/vz/template/iso/ folder.
If the image already exists it will not be downloaded again.
If the file is compressed with gz, xz or zip it will also uncompress it.
Returns the full path of downloaded image.
# Download Debian 12 image
DEBIAN_URL='https://cloud.debian.org/images/cloud/bookworm/latest/debian-12-genericcloud-amd64.qcow2'
./download-cloud-image.sh $DEBIAN_URLUsage: ./download-cloud-template.sh <url> [OPTIONS]
<url> Url of template to download.
--filename, -f Renames the downloaded file.
--no-clobber, -nc Doesn't overwrite an existing template.
--help, -h Display this help message.
Downloads a LXC template from given url into /var/lib/vz/template/cache/ folder.
You can use --filename to rename the resulting file.
If the template already exists it will not be downloaded again.
Please note that this script DOES NOT uncompress the resulting file. LXCs templates can be used in compressed format.
Returns the full path of downloaded template.

The following is a compilation about the subject I found around the net. Please read if you wish to follow this path.
Using Docker on LXC is not recommended by Proxmox team. However, certain features of LXC like reduced memory usage and bind mount points between containers and host may be an incentive to go against this recommendation.
Two discussions about the pros and cons of each alternative may be found here and here.
Backups (both to local storage and to Proxmox Backup Server) work fine.
However, please note that the contents of /var/lib/docker will be included in backups by default. This is probably NOT what you want.
This folder often grows in size very quickly. And its contents (except for Docker volumes, see below) may easily be downloaded or rebuilt.
To avoid this, you may use a .pxarexclude file to exclude its contents from the backup archive.
cat > /.pxarexclude <<EOF
var/lib/docker/
EOFPlease note that in this case you SHOULD NOT use Docker volumes to store any persistent data which is important since they are kept at this location (and, again, will not be included in backups).
Instead you should use Docker bind mounts which mounts a file or directory from the Docker host (LXC, in our case) into a Docker container. All files from LXC filesystem will be included into backups.
Proxmox VE 8.1 uses ZFS 2.2 which finally supports overlay2 out of the box.
All previous workarounds should be considered deprecated.
Starting with Proxmox VE 8.1 the new-ct.sh script will always assume --no-docker-volume, never creating the workaround volume needed for previous Proxmox VE versions.
