# Audiobookshelf as a rootless Podman Quadlet unit, behind the shared Caddy unit
# (see caddy/playbook.yml).
#
# Unlike bitwarden/ and tandoor/, this app has no database to attach: its state
# is one SQLite file plus files under ~/podman-data/audiobookshelf, so there is
# no postgres role here and nothing to restore from the shared cluster.
#
# 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.)
#
# Run with: ansible-playbook -u tanshu audiobookshelf/playbook.yml

    # unit references {{ network_name }}.network, and Quadlet fails *unit
    # generation* (so `systemctl --user start` reports "unit not found") when a
    # referenced .network file does not exist yet. The same include writes the
    # Caddy-side drop-in that attaches Caddy to this network.
    #
    # network_name is a play var, so the include can see it directly.
