jfxs/ansible repository overview

⁠Docker alpine Ansible

A Docker image to run Ansible⁠ playbooks. Ansible-lint⁠ to test playbooks is also included.

• lightweight image based on Alpine Linux,
• multiarch with support of amd64 and arm64,
• non-root container user,
• automatically kept up to date by Renovate⁠ (base image, Ansible and dependency versions),
• image signed with Cosign⁠,
• a software bill of materials (SBOM) attestation added using Syft⁠,
• available on Docker Hub and Quay.io.

The main repository.

The Docker Hub registry.

The Quay.io registry.

Since Ansible version 2.10, the Docker image has only ansible-core without any collection. It could be necessary to install them. This image includes:

• ansible-core⁠
• ansible-lint⁠
• go-task⁠
• hvac⁠
• jc⁠
• jmespath⁠ and netaddr⁠, for the Ansible filters
• jq⁠, curl, git, rsync, sshpass, openssh-client and vim
• pytest⁠
• testinfra⁠
• yamllint⁠
• yq⁠

⁠Running Ansible

Example to run Ansible playbooks in your current directory:

docker run -it --rm -v $(pwd):/ansible jfxs/ansible ansible-playbook playbook.yml

To install collections:

docker run -it --rm -v $(pwd):/ansible jfxs/ansible /bin/sh -c "ansible-galaxy collection install ansible.utils && ansible-playbook playbook.yml"

To test playbooks in your current directory with ansible-lint:

docker run -it --rm -v $(pwd):/ansible jfxs/ansible ansible-lint playbook.yml

The container user is 10010. With a bind mount on a Linux host, run the container with your own user to be able to write in the current directory (the image supports arbitrary user IDs):

docker run -it --rm -u "$(id -u):$(id -g)" -v $(pwd):/ansible jfxs/ansible ansible-playbook playbook.yml

The system SSH client configuration of the image (/etc/ssh/ssh_config) disables the host key checking (StrictHostKeyChecking no). Override it with your own ssh_config or SSH options if you need it.

⁠Built with

Docker latest tag is 2.21.4-003, 2.21, 2⁠.

The complete software bill of materials (SBOM) of each published image, with its known vulnerabilities, is collected in the sbom-docker⁠ repository, under the component docker-ansible.

Dockerhub Overview page⁠ has the details of the last published image.

⁠Versioning

Docker tag definition:

• the ansible-core version used,
• a dash
• an increment to differentiate build with the same version starting at 001

<ansible_version>-<increment>

Example: 2.21.4-001

⁠Signature and attestation

Cosign⁠ public key:

-----BEGIN PUBLIC KEY-----

The public key is also available online: https://gitlab.com/op_so/docker/cosign-public-key/-/raw/main/cosign.pub⁠.

To verify an image:

cosign verify --key cosign.pub $IMAGE_URI

To verify and get the SBOM attestation:

cosign verify-attestation --key cosign.pub --type spdxjson $IMAGE_URI | jq '.payload | @base64d | fromjson | .predicate'
