Adds opt-in Anubis bot protection in front of the Funkwhale front container. Default: off.

What

  • New service block in the compose stack, gated by funkwhale_with_anubis (default false)
  • Vendors the upstream Funkwhale botPolicy.yaml verbatim under roles/funkwhale/files/
  • Bypass list (from upstream): /api, /federation, /rest, /.well-known, /media, /staticfiles — keeps Subsonic clients, federating pods, and ActivityPub well-knowns unchallenged
  • When enabled, Anubis takes the host port (127.0.0.1:5000) the front container had, and proxies to http://front:8080 internally — no nginx vhost change required

Verified flag-on / flag-off

Rendered the compose template both ways:

  • funkwhale_with_anubis: false → no anubis service, front owns the host port
  • funkwhale_with_anubis: trueanubis service emitted, front loses its ports: binding

Verified with

yamllint -c .yamllint.yaml .
ansible-lint --profile safety roles/funkwhale
ansible-playbook --syntax-check -i hosts/prod playbooks/funkwhale.yml

Stacking

Depends on feat/funkwhale-core. After that merges, rebase this onto master.
Parallel with feat/funkwhale-backup — they touch disjoint code paths.

Adds roles/docker, a generic role that installs the upstream Docker
apt repository and the v2 'docker compose' plugin. No playbook
references it yet -- it is consumed by the upcoming funkwhale role
and is intentionally generic so any future containerised service can
reuse it.

Highlights:
- pulls Docker's official GPG key into /etc/apt/keyrings
- installs docker-ce + cli + containerd.io + buildx + compose plugin
- exposes docker_group_users so the funkwhale service user can run
  docker without sudo

Verified with: yamllint -c .yamllint.yaml .
Adds a Funkwhale role and playbook for music.bonfire.link.

Architecture:
  client → host nginx (TLS, big bodies)
            → front container (in compose stack)
              → api / celery / postgres / redis (in compose stack)
  audio  → S3-compatible object storage (Storj gateway by default),
           streamed directly to clients via signed URLs

Highlights:
  - public + federated by default; e-mail verification on
  - 5G upload ceiling (4h FLAC/WAV sets); proxy_request_buffering off
  - direct streaming from Storj (PROXY_MEDIA=false +
    AWS_QUERYSTRING_AUTH=true); the bucket can stay private
  - storage backend toggle (s3 | local) for Vagrant/dev
  - assert.yml refuses placeholder secrets; warns when registration
    is on without real SMTP
  - depends on roles/docker (added in feat/docker-role); reuses
    common, fail2ban, certbot and nginx roles untouched
  - public-repo-safe: no real secrets committed; vault layout
    documented in roles/funkwhale/README.md

Two add-ons land in follow-up PRs and are explicitly out of scope
here:
  - feat/funkwhale-anubis  — Anubis bot protection
  - feat/funkwhale-backup  — nightly pg_dump → S3

Verified with:
  yamllint -c .yamllint.yaml .
  ansible-playbook --syntax-check -i hosts/prod playbooks/funkwhale.yml
  jinja render of every template (compose YAML re-parses cleanly)
… container

Adds Anubis (https://anubis.techaro.lol) as an opt-in service in the
docker-compose stack, gated behind funkwhale_with_anubis (default
false). When enabled, Anubis takes the host port that the front
container had, and proxies to http://front:8080 internally.

Bypass policy is the upstream Funkwhale botPolicy.yaml verbatim
(vendored under roles/funkwhale/files/), which exempts /api,
/federation, /rest, /.well-known, /media and /staticfiles -- so
Subsonic clients, federating pods and ActivityPub well-knowns are
not challenged.

Verified with:
  yamllint -c .yamllint.yaml .
  ansible-lint --profile safety roles/funkwhale  (passes)
  ansible-playbook --syntax-check -i hosts/prod playbooks/funkwhale.yml
  jinja render of compose template with anubis on/off
