Error response from daemon: failed to set up container networking: driver failed programming external connectivity on endpoint webapp-skeleton-nginx-1 (8593fd07c2b269968a3547d276611063a227abce0699b6fe24c489acc66304a9): Bind for 0.0.0.0:8080 failed: port is already allocated

My sugestinon is to change docker-compose.yml to
adminer:
image: dockette/adminer:dg
ports:
- 8081:80

Start with docker-compose.yml and reproduce the issue using docker-compose up. Inspect the published ports for the nginx and adminer services, especially the mapping involving host port 8080. Done means the compose stack starts without a port-allocation error and the affected service remains reachable on its configured host port.
