This code builds container images for various Linux distributions, for use as Ansible molecule testing platforms.
Two varieties are available, namely:
- Podman / Docker images, for testing your playbooks in Podman or Docker containers
- containerDisk images, for testing your playbooks in KubeVirt VMs
Our Containerfiles (in the podman/ directory):
| Linux Distribution | Containerfile | Image name |
|---|---|---|
| CentOS Stream 8 | Containerfile.centos-stream8 |
molecule-platform:centos8 |
| CentOS Stream 9 | Containerfile.centos-stream9 |
molecule-platform:centos9 |
| Debian 12 (Bookworm) | Containerfile.debian12 |
molecule-platform:debian12 |
| Fedora 40 | Containerfile.fedora40 |
molecule-platform:fedora40 |
| Fedora 41 | Containerfile.fedora41 |
molecule-platform:fedora41 |
| Fedora 42 | Containerfile.fedora42 |
molecule-platform:fedora42 |
| SLE BCI (SLES 15) based | Containerfile.sle15 |
molecule-platform:sle15 |
| Ubuntu 22.04 (Jammy Jellyfish) | Containerfile.ubuntu2204 |
molecule-platform:ubuntu2204 |
| Ubuntu 24.04 (Noble Numbat) | Containerfile.ubuntu2404 |
molecule-platform:ubuntu2404 |
Example Containerfiles:
- Our Debian & Ubuntu images are based on
Containerfile.example-debian, from https://github.com/alehaa/docker-debian-systemd - Our images for the Red Hat family are based on UBI 9 -
Containerfile.example-ubi9-init, fromregistry.access.redhat.com/ubi9/ubi-init:9.5-1734512956
Container images built from these files are available at https://hub.docker.com/r/cliffordw/molecule-platform.
To build your own images from this source, you can build all images with:
make build-containerOr build individual images with these commands:
podman build -f podman/Containerfile.centos-stream8 -t molecule-platform:centos8 .
podman build --pull -f podman/Containerfile.centos-stream9 -t molecule-platform:centos9 .
podman build -f podman/Containerfile.debian12 -t molecule-platform:debian12 .
podman build --pull -f podman/Containerfile.fedora40 -t molecule-platform:fedora40 .
podman build --pull -f podman/Containerfile.fedora41 -t molecule-platform:fedora41 .
podman build --pull -f podman/Containerfile.fedora42 -t molecule-platform:fedora42 .
podman build -f podman/Containerfile.sle15 -t molecule-platform:sle15 .
podman build -f podman/Containerfile.ubuntu2204 -t molecule-platform:ubuntu2204 .
podman build -f podman/Containerfile.ubuntu2404 -t molecule-platform:ubuntu2404 .Other images that already contain systemd:
registry.access.redhat.com/ubi9/ubi-init:9.5quay.io/centos/centos:stream10
An example Molecule configuration can be found in molecule/podman/.
Run with:
python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install molecule 'ansible-core<2.17'
molecule test -s podmanAn example Molecule configuration can be found in molecule/podman/.
Our Containerfiles (in the kubevirt/ directory):
Container images built from these files are available at https://hub.docker.com/r/cliffordw/kubevirt-containerdisk.
To build your own images from this source, you can build all images with:
make build-vmOther available images (requires authentication to pull):
registry.redhat.io/rhel9/rhel-guest-imageregistry.redhat.io/rhel8/rhel-guest-image
An example Molecule configuration can be found in molecule/kubevirt/.
Run with:
python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install molecule 'ansible-core<2.17'
python3 -m pip install -r molecule/shared/kubevirt-requirements.txt
