This post is a quick reference guide to setup aws cli and pushing a docker image to ECR.

AWS Info

Keep following things handy while working with aws CLI commands

account_id
region=us-west-2
iam_user_access_key
iam_user_secret

Install aws cli

https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-windows.html

verify that it works

aws --version

Configure AWS CLI

aws configure

# requires
iam_user_access_key
iam_user_secret
region=us-west-2
FORMAT=json

# verify
aws sts get-caller-identity

Create repository

https://console.aws.amazon.com/ecr/repositories

Simple form, just provide name of the private repo

account_id.dkr.ecr.us-west-2.amazonaws.com/reponame

Build docker image

git clone https://github.com/repo

docker build -t reponame:tag Dockerfile_location

Push Docker Image to AWS Repo

https://docs.aws.amazon.com/AmazonECR/latest/userguide/docker-push-ecr-image.html

Let docker know how to login to ECR

aws ecr get-login-password --region us-west-2
#copy the token
docker login --username AWS account_id.dkr.ecr.us-west-2.amazonaws.com
#paste the token

List docker images and locate the one you built

docker images

Tag and push the image to ECR

docker tag image_id account_id.dkr.ecr.us-west-2.amazonaws.com/reponame:tag
docker push account_id.dkr.ecr.us-west-2.amazonaws.com/reponame:tag

Now you have an image in ECR

https://us-west-2.console.aws.amazon.com/ecr/repositories?region=us-west-2
