In this short tutorial we will see how we can push a Docker Image to a private or public registry in ECR.
Step 1: Create an AWS ECR Repository
A Private Repository: It will be managed and accessed by IAM and Registry Policy Permissions and not be accessible by everyone.
OR
A public Repository: It will be accessible by everyone.

Private ECR Repo:
Public ECR Repo:
Step 2: Prepare Docker Image to be pushed to ECR
I have taken an example of a simple Nodejs application got from the internet and created an image on Docker Desktop using following command from the directory where DOCKERFILE for my app is present.
Tag the image before pushing to ECR
