# sms-wa-bridge as a rootless Podman Quadlet unit on emily, behind the shared
# Caddy unit (caddy/playbook.yml).
#
# The app is SMS webhook -> routing rules -> WhatsApp, with no LLM in the path:
# an Android automation (MacroDroid) POSTs each SMS to https://bridge.tanshu.dev/sms
# with an X-Auth header, rules.json decides who gets it, and whatsapp-web.js
# sends it from a linked WhatsApp account. It was deployed on monoco as a plain
# `docker run` container built from the Dockerfile now vendored at
# files/build/ — see readme.md.
#
# Connects as the container user and runs everything as that user: the Quadlet
# units belong to it, so the connection's PAM session is what makes
# `systemctl --user` work without any environment juggling.
#
# gather_facts is required: podman_user and the home directory come from the
# user_id / user_dir facts.
#
# The rootless-Podman prerequisites (installing podman, enabling lingering, the
# low-port sysctl, creating the Quadlet directory) are deliberately NOT applied
# here. They are the shared task file at caddy/roles/podman/tasks/main.yaml, and
# a host that has already run caddy/playbook.yml has them:
#
#   - name: Rootless Podman prerequisites
#     ansible.builtin.include_tasks: "{{ playbook_dir }}/../caddy/roles/podman/tasks/main.yaml"
#
# The variables this play needs are duplicated at the top of vars/default.yml, so
# it stands on its own. (Applying the commented include above would also need
# podman_unprivileged_port_start, which lives in caddy/vars/default.yml.)
#
# The one prerequisite it *does* need beyond Caddy's is buildah, and only on the
# build path: `podman` Recommends it on Ubuntu, so caddy/roles/podman has already
# installed it. Nothing needs it when the image is loaded from monoco, which is
# the recommended route in readme.md.
#
# Run with: ansible-playbook -u tanshu sms-wa-bridge/playbook.yml
