Normally when you create a Volume, it will store in Docket Host, you can also tell the folder which you want docket to store the volume.
docker run -p 8080:3000 -v /var/www node # run with a node image
You can check the volume information by:
docker inspect <container_id>
In the output JSON, you need to find "Mount" prop, it contains the information.
If you want to create a custom folder to store the volme, you can do:
docker run -p 8080:3000 -v $(pwd):/var/www node
Remove container with volume:
docker rm -v <container_id>

We can create a node express app and put that into docker with volume.
npm i -g express express-generator
Create an express app:
express ExpressSite --hbs
Cd to the project and put souce code into docker, meanwhile we want to npm 'npm start' as well.
# create a volume: -v # $(pwd): current path, means you want to create volume in your folder # -w: current working directory "/var/www" # start the image node # run script: npm start docker run -p 8080:3000 -v $(pwd):/var/www -w "/var/www" node npm start
