Once I build the docker image using below command 
#docker build --tag flask-py-docker-2 .
this has created my images in my local ..please see below.
#flask-py-docker-2              latest              a8fdbfef3095   23 hours ago    906MB

Once I ran the docker run with above image on particular port it got started in my local.

##docker run -d -p 5000:5000 flask-py-docker-2

and my simple hello world website is up and running. see png attachment

Once it website is published we have to tag the docker image and push it to the ECR, using below commands.

docker tag flask-py-docker-2  527805459418.dkr.ecr.ap-northeast-1.amazonaws.com/flask-v1:latest

push command

docker push 527805459418.dkr.ecr.ap-northeast-1.amazonaws.com/flask-v1:latest


this will push the docker image to ECR.

Thanks YOu.
Looking forward to hear.
