Let us create a sample docker file for the node.js application
Build a Docker image using the Dockerfile
docker build -t app1 -f dockerfile.nodeapp .
Verify the size of the docker image.
To reduce the size of Docker images, we use multi-stage Docker builds.
Create a multi-stage Dockerfile.
Build a docker image with the new docker file.
docker build -t app1:v2 -f dockerfile.multi .
Verify the size of the docker image.
