[Docker] Hooking a Volume to Node.js Source Code

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
