Dockerize a node-js app

Learn how to use docker and dockerize a simple nodejs app for backend.

How to Use

  • You can download docker dekstop from the official page
  • Clone this repository
  • Make docker image by run this script :
docker build -t image_name .
  • You can check if success by run this script : docker images you will see something like this :
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
image_name          latest              023b3747f3d9        9 minutes ago       904 MB
node                8                   8eeadf3757f4        4 weeks ago         901 MB
  • The important thing is that we need to tell docker how to map the port. And finally you can run with :
docker run -p 8080:3500 -d backend-app

Now you can access the app will run at 8080
