Puppet Class: docker

Defined in:
modules/docker/manifests/init.pp

Overview

Class docker

Install docker on the host, at the desired version. It allows to choose whether to install a version from the official debian repositories or from dockerproject.org. It also declares the service

Parameters

package_name

Docker is going through various transitions changing package

names multiple times already. Support that so we can choose which one we want. Defaults to docker.io

On Debian bullseye the 'libapparmor1' package is now installed by default but the userspace uilities package 'apparmor' is not. This leads to Debian bug #989781 (bugs.debian.org/cgi-bin/bugreport.cgi?bug=989781). Therefore we need to explicitly install it if on bullseye. The good part: actually working apparmor for docker as opposed to previous distro versions.

Parameters:

  • package_name (Optional[String]) (defaults to: undef)
