Login Succeeded

4. Build the image and publish

For this example, we will use this repository – docker-library/python: Docker Official Image packaging for Python (github.com).

Clone the repository and build the docker image.

docker build  -f 3.9/buster/slim/Dockerfile -t python:3-8-slim .

Tag the image.

docker tag python:3-8-slim xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/python:3-8-slim

Publish the image.

docker push xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/python:3-8-slim

% docker push xxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/python:3-8-slim
The push refers to xxxxxxxxx [526470662813.dkr.ecr.us-east-1.amazonaws.com/python]
a18688d0f743: Pushed 
92a2f04a63cd: Pushed 
e02f907200b6: Pushed 
5d8b6ff688d4: Pushed

Now you can see the image in the ECR.
