running docker inside lxc container on proxmox

Docker install notes

Source: Docker install

Proxmox: Need to add lxc.aa_profile = unconfined, security.privileged = true and lxc.cap.drop = into the container config in /etc/pve/lxc/ per forums and here.

sudo apt-get update

The below will fail if running on ProxMox due to specific kernel

sudo apt-get install -y \
    linux-image-extra-$(uname -r) \
    linux-image-extra-virtual

Install the packages to allow repository

sudo apt-get install -y \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common

Add the GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Set up the repository

# For amd64
sudo add-apt-repository \
    "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
    $(lsb_release -cs) \
    stable"

Add the packages

sudo apt-get update
sudo apt-get install -y docker-ce

Test install success

sudo docker run hello-world

Main thing to note is the amendments you need to make to the lxc <id>.conf config file in the first paragraph above otherwise Docker won't run and you'll get apparmor errors etc.
