 # wulf-ansible
 
-Ansible playbooks used by Semaphore for Wulf infrastructure automation.
-
-## Collection requirements
-
-Install required Ansible collections before running playbooks locally or in a new Semaphore worker environment:
-
-```bash
-ansible-galaxy collection install -r collections/requirements.yml
-```
-
-Currently required collections:
-
-- `community.docker`
-- `community.general`
-- `ansible.posix`
-
-## Docker baseline
-
-Semaphore template: **Docker Baseline**
-
-Playbook:
-
-```bash
-ansible-playbook playbooks/docker.yml
-```
-
-The Docker role:
-
-- supports Debian/Ubuntu apt-based hosts,
-- removes conflicting distro/container packages,
-- configures Docker's official apt repository,
-- installs Docker Engine, Buildx, and Compose V2 plugin,
-- configures Docker daemon log rotation and live-restore,
-- enables Docker,
-- adds the target Ansible user to the `docker` group,
-- creates `/opt/stacks`,
-- enables IPv4 forwarding,
-- optionally disables IPv6,
-- creates shared Docker networks such as `pangolin`,
-- verifies `docker --version` and `docker compose version`.
-
-### Docker role variables
-
-```yaml
-docker_package_state: present       # set to latest when intentionally upgrading Docker packages
-docker_stacks_dir: /opt/stacks
-docker_networks:
-  - pangolin
-docker_disable_ipv6: false
-docker_run_hello_world: false       # optional runtime pull/run verification
-```
-
-To run a full runtime verification during provisioning:
-
-```yaml
-docker_run_hello_world: true
-```
