### docker compose successfully return.

```$ docker ps -a

```

But `http://localhost:8080` not return any respond.

```$ curl 0.0.0.0:8080 -vvv
* Trying 0.0.0.0:8080...
* connect to 0.0.0.0 port 8080 failed: Connection refused
* Failed to connect to 0.0.0.0 port 8080: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 0.0.0.0 port 8080: Connection refused```

Start by inspecting the Docker Compose configuration alongside the reported `docker ps -a` output, focusing on the phpmyadmin container and its published port. Reproduce the failure with `curl 0.0.0.0:8080 -vvv`; the issue is done when phpMyAdmin responds at `http://localhost:8080`.
