This role enhances the original geerlinguy docker role and uses the Ansible volumes plus role to add support for the overlayfs driver in Docker.

Requirements

First, run ./configure to download the necessary requirements into sibling folders.

roles_path = ./roles:./roles/community

Molecule Tests

To run tests, you need to create a Fedora-33 Packer image with cgroup V1 and name it yourpseudo/fedora-33. Here’s how:

git clone [email protected]: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

Alternatively, you can use a pre-built image (tcharl/fedora-33-cgroupv1) available on Vagrant Cloud, so you can simply run molecule test.

Role Variables

Only dependency variables should be considered, not those of the dependencies. For more details, check the molecule tests.

Dependencies

As mentioned, the key dependencies are:

• geerlinguy docker role
• Ansible volumes

Example Playbook

Refer to the declared vars in the molecule test, and see their impact.
