instruction: Create a Dockerfile for Node.js, Alpine Linux with production best practices
output: ```dockerfile
  from the current directory.
  
  services:
   app:
   image: node:18-alpine
   command: sh -c "yarn install && yarn run dev"
   ports:
   - 127.0.0.1:3000:3000
   working_dir: /app
   volumes:
   - ./:/appFinally, you need to migrate the environment variable definitions using the environment key.
  
  services:
   app:
   image: node:18-alpine
   command: sh -c "yarn install && yarn run dev"
   ports:
   - 127.0.0.1:3000:3000
   working_dir: /app
   volumes:
   - ./:/app
   environment:
   MYSQL_HOST: mysql
   MYSQL_USER: root
   MYSQL_PASSWORD: secret
   MYSQL_DB: todosDefine the MySQL serviceNow, it's time to define the MySQL service. The command that you used for that container was the following:
  
  $ docker run -d \
   --network todo-app --network-alias mysql \
   -v todo-mysql-data:/var/lib/mysql \
   -e MYSQL_ROOT_PASSWORD=secret \
   -e MYSQL_DATABASE=todos \
   mysql:8.0
  First define the new service and name it mysql so it automatically gets the network alias. Also specify the image to use as well.
  
  services:
   app:
   # The app service definition
   mysql:
   image: mysql:8.0Next, define the volume mapping. When you ran the container with docker run, Docker created the named volume automatically. However, that doesn't
  happen when running with Compose. You need to define the volume in the
  top-level volumes: section and then specify the mountpoint in the service
  config. By simply providing only the volume name, the default options are
  used.
  
  services:
   app:
   # The app service definition
   mysql:
   image: mysql:8.0
   volumes:
   - todo-mysql-data:/var/lib/mysql
  
  volumes:
   todo-mysql-data:Finally, you need to specify the environment variables.
  
  services:
   app:
   # The app service definition
   mysql:
   image: mysql:8.0
   volumes:
   - todo-mysql-data:/var/lib/mysql
   environment:
   MYSQL_ROOT_PASSWORD: secret
   MYSQL_DATABASE: todos
  
  volumes:
   todo-mysql-data:At this point, your complete compose.yaml should look like this:
  
  services:
   app:
   image: node:18-alpine
   command: sh -c "yarn install && yarn run dev"
   ports:
   - 127.0.0.1:3000:3000
   working_dir: /app
   volumes:
   - ./:/app
   environment:
   MYSQL_HOST: mysql
   MYSQL_USER: root
   MYSQL_PASSWORD: secret
   MYSQL_DB: todos
  
   mysql:
   image: mysql:8.0
   volumes:
   - todo-mysql-data:/var/lib/mysql
   environment:
   MYSQL_ROOT_PASSWORD: secret
   MYSQL_DATABASE: todos
  
  volumes:
   todo-mysql-data:Run the application stackNow that you have your compose.yaml file, you can start your application.Make sure no other copies of the containers are running first. Use docker ps to list the containers and docker rm -f <ids> to remove them.Start up the application stack using the docker compose up command. Add the
  -d flag to run everything in the background.
  
  $ docker compose up -d
  When you run the previous command, you should see output like the following:
  
  Creating network "app_default" with the default driver
  Creating volume "app_todo-mysql-data" with default driver
  Creating app_app_1 ... done
  Creating app_mysql_1 ... doneYou'll notice that Docker Compose created the volume as well as a network. By default, Docker Compose automatically creates a network specifically for the application stack (which is why you didn't define one in the Compose file).Look at the logs using the docker compose logs -f command. You'll see the logs
