That title is a doosey, writing this for a friend.
Ive been using proxmox for a while now and even more recently ive been using docker for some tasks, im still a fan of FreeBSD jails, its just that docker containers can be convenient if I’m already on Linux.
Start by creating your container, this initial setup is normal, give yourself enough RAM, CPU, and storage as you will need. And of course, use Debian 9 or 10.
Next your host needs to have some modules added, you can configure
/etc/modules-load.d/modules.conf by adding the required modules below to that file.
And if you dont want to reboot to enable the changes you can run
modprobe aufs modprobe overlay
Now that you’ve got that done, and your container is setup and not started you’re ready to continue.
Navigate to and edit the following file
<vid> is the id of your container. Add/modify the following lines. You can use your preferred editor for this, id recommend
# Added for docker lxc.apparmor.profile: unconfined lxc.cgroup.devices.allow: a lxc.cap.drop:
Great! Now you can start, and then enter the
pct start <vid> pct enter <vid>
Add some requirements for docker and the docker repository.
# Add some required packages apt install apt-transport-https ca-certificates curl gnupg2 software-properties-common # add the docker repository curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add - add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
apt update apt install docker-ce
Update the docker composer that ships with Debian, I’ve not found a package for this yet, so this is a bit of a workaround.
curl -L "https://github.com/docker/compose/releases/download/1.23.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose chmod +x /usr/local/bin/docker-compose
/usr/local/bin to the path by adding
# add the following line to ~/.bashrc PATH=/usr/local/bin:$PATH
Once that’s done just
pct enter <vid> again.
That’s it! you’re ready to move onto the next step witch should be installing your docker container via docker compose! :3
