Tip: use docker-compose or docker compose without dash.

Access the aplication with the browser using localhost:8080 to acess via Nginx (Reverse proxy) or localhost:3000 for direct connection to node app container. The application has two routes: / and /name/:yourName where the yourName parameter is the name for a new register on the DB.

Docker command tips

Build Docker image locally

docker build -t adrianokerber/laravel .

Run Docker image on a container

docker run -d --name laravel -p 8000:8000 adrianokerber/laravel

Remove all Docker containers

docker rm $(docker ps -aq) -f

# List running containers
docker ps

# List images
docker images

# Remove container
docker rm <container_id>

# Remove image
docker rmi <image_id>
