Documented steps
Bind-mount host paths with `volumes: - /host/path:/container/path`; in rootless mode the host user maps to UID 0 inside, so permissions must allow both.
For host ports below 1024 in rootless mode, go rootful (system podman.socket/sudo) or map to an unprivileged host port like `8080:80`.
Use named volumes for persistent data; ownership follows the rootless user's mapped UID.
Storage lives under ~/.local/share/containers — leave disk headroom there.
To use unmodified docker-compose against a rootless podman: enable the user podman.socket and set DOCKER_HOST=unix:///run/user/$(id -u)/podman/podman.sock.
Known gotchas
Rootless containers can't bind ports <1024 without rootful podman — the most common 'can't reach it' cause.
Bind-mount read failures often come from host file ownership — fix permissions/chown.
SELinux on Fedora/RHEL can block bind mounts — you may need :Z/:z relabel or setsebool.
