Using Docker containers you can avoid installing npm packages on your actual machine for any project.
Line 1: Use a specific version of node.
Line 2: Create and use the
/app directory as the working directory.
Line 3: Copy everything on the same directory as the Dockerfile and place it within the
/app directory for our image.
Line 4: Run
With the above Dockerfile we can now build our image and run our container . We have 2 possible routes. Using the Docker CLI or Docker-Compose.
The following command will build your Docker Image.
docker build --rm -t npmProject .
The following command will run your container and mount your current directory into the container working directory.
docker run --rm -it -v $(pwd):/app npmProject sh
Docker-Compose may be a better route because we can mount our directory but ignore the
node_modules directory which can sometimes become very heavy.
Line 1: The version of Docker-Compose we want to use (this is relative to the syntax used)
Line 2: This is default syntax for docker-compose specifying each container needed as a service.
Line 3: Name of the “service”.
Line 4: The name of the container. By default Docker gives random names to all containers.
Line 5: Specifying where the Dockerfile we want to build our image from is.
Line 6: The name of the image we create in the process. if
build was not used in the docker-compose.yaml it would try to look for an image with this name locally and then on
Line 7: Beginning for volume mount entries.
Line 8: Mount the current directory to the containers
Line 9: This line is special, I am not sure why yet but this line essentially tells docker-compose ignore the mounting of the
node_modules directory within the container to our actual machine.
Thats all for today. I wonder if this is a good tutorial.
