Solution to Challenge

Solution

1. To build and tag an image in a single command with challenge and try as image and tag name respectively:

   docker image build -t <your_username>/challenge:try .
   

   or for Dockerfile.prod:

   docker image build -f Dockerfile.prod -t <your_username>/challenge:try .
   

2. List down all images:

   docker image ls
   

3. Push your image to the repository:

   docker push <your_username>/challenge
   

   or with tag:

   docker push <your_username>/challenge:try
   

4. Verify on your repository that the image has been built.

5. A container is run according to the required instructions, using the image you built above:

   docker run -it --rm --name nodecontainer -p 8080:3000 \
   <your_username>/challenge:try
   

   • -it runs an interactive session.
   • --rm removes the container after the container stops.
   • --name is used to name the container as nodecontainer.
   • -p is used to define both the exposed port (8080) and the default port (3000) on which node is running.
   • Image name is <your_username>/challenge:try that was built above.
