# docker_app

Shared adapter role for single-container Docker Compose applications.
Application roles set `docker_app_*` variables and include this role.

`docker_app` validates single-container app inputs and delegates the common
Compose lifecycle to `compose_project`.

It supports direct host-port publishing with UFW rules or Traefik routing via
labels and a shared Docker network.
