Node.js is not running in Docker is my docker-compose.yml correct? - node.js

Question

The problem:
I'm trying to set up a Docker WordPress development environment on Windows 11 with wsl2. I created a docker-compose.yml and everything works apart from the node install. The container tries to start it and then just stops. Is something in my docker-compose file wrong?
I want to use node because I use gulp, npm and browser sync for my WordPress themes.
This is my docker-compose.yml:
version: "3.9"
services:
db:
image: mysql:5.7
volumes:
- dbdata:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: somewordpress
MYSQL_DATABASE: wordpress
MYSQL_USER: wordpress
MYSQL_PASSWORD: wordpress
wordpress:
depends_on:
- db
image: wordpress:latest
volumes:
- wp-content:/var/www/html/wp-content
ports:
- "8000:80"
restart: always
environment:
WORDPRESS_DB_HOST: db:3306
WORDPRESS_DB_USER: wordpress
WORDPRESS_DB_PASSWORD: wordpress
node:
restart: "no"
image: node:latest
container_name: nodejs
depends_on:
- wordpress
volumes:
- node-data:/usr/src/app
ports:
- 3000:3000
- 3001:3001
volumes:
dbdata:

Answer 1

You have to use a Dockerfile otherwise it will never ever work!

Answer 2

Problem is that you have mentioned to spin up the docker container but just think for a sec how will you command node to tell that what it needs to do .When it sees no action commanded it basically closes up .
Solution
Long way - You can use up a dockerfile, as mentioned by Tom , dockerfile is generally used to containerise your application so whatever code you need do just write it , then build your code into a docker image with node using Dockerfile , but in that case trouble is that everytime you are doing any code change you have reiterate over the same process and again build your code.
Another simple way I could think of is add a command:npm start in your node image and this should help you probably
Forgive me if I have suggested something wrong because I am also learner in docker :)
