Containerization OverlayFS

This role enriches the original geerlinguy docker role and use the Ansible volumes plus role in order to add overlayfs driver support configuration for docker

Requirements

You should first execute ./configure first, which will download the requirements in siblings folders. roles_path = ./roles:./roles/community

Molecule tests

To execute test, build your own Fedora-33 Packer image enabling cgroup V1 and call it yourpseudo/fedora-33. Procedure:

git clone git@github.com:chef/bento.git
cd "$(dirname ${BASH_SOURCE[0]})/bento/packer_templates/fedora"
sed -i -e "s/dnf -y install \(.*\)/dnf -y install \1 grubby \&\& grubby --update-kernel=ALL --args=\"systemd.unified_cgroup_hierarchy=0\" --make-default/" bento/packer_templates/fedora/scripts/install-supporting-packages.sh
packer build -var "box_basename=$distroversion" -only=$PACKER_VM_DRIVER $distroversion.json

cd "$(dirname ${BASH_SOURCE[0]})/bento/builds
vagrant box add $distroversion.virtualbox.box --name platform/$distroshortversion

However, a base image (tcharl/fedora-33-cgroupv1) with these properties has been published to vagrant cloud so executin molecule test will suffice!
