+## Dockerize the project
+
+Update the (Dockerfile)[https://github.com/unboxed/retrofit/blob/main/Dockerfile].
+
+Run
+```
+docker build . -t retrofit
+docker run -p 3000:3000 retrofit
+```
+
+Check it's up and running at `http://localhost:3000`.

+## Create an Amazon ECR Repository
+
+In the AWS console go to [ECR Private Repositories](https://console.aws.amazon.com/ecr/private-registry/repositories), click `Create Repository` and create a new private repository. 
+
+(See [AWS documentation](https://docs.aws.amazon.com/AmazonECR/latest/userguide/repository-create.html).)
+
+<a id='push-the-image'></a>
+## Push the Docker image to Amazon ECR
+
+### Authenticate your Docker client to the ECR registry:
+
+`aws ecr get-login-password --region <region> | docker login --username AWS --password-stdin <aws_account_id>.dkr.ecr.<region>.amazonaws.com`
+
+### Tag the Docker image with the ECR repository URI:
+
+Run `docker images` to get the image id.
+
+Get the ECR repository URI from [the AWC ECR console](https://console.aws.amazon.com/ecr/private-registry/repositories).
+
+Tag the docker image: 
+
+`docker tag <image_id> <repository_uri>:<optional_tag>`
+
+### Push the Docker image:
+
+`docker push <repository_uri>:<optional_tag>`
+
+(See [AWS documentation](https://docs.aws.amazon.com/AmazonECR/latest/userguide/docker-push-ecr-image.html).)
