# Gitea as a rootless Podman Quadlet unit on emily, behind the shared Caddy
# unit (caddy/playbook.yml), with git-over-SSH still arriving on the host's own
# port 22 so that no client has to change its remote.
#
# 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.)
#
# Unlike bitwarden/ and tandoor/ there is no postgres role here: this Gitea runs
# on SQLite, which monoco's live app.ini confirms (`DB_TYPE = sqlite3`,
# `PATH = /data/gitea/gitea.db`). The unused Docker-era Postgres variant that
# used to sit beside this file was removed for the same reason.
#
# Run with: ansible-playbook -u tanshu gitea/playbook.yml

    # 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.
