1 INTRODUCTION
ECR: Amazon Elastic Container Registry (ECR) is a fully managed Docker container registry
that makes it easy for developers to store, manage, and deploy Docker container images.
Amazon ECR is integrated with Amazon Elastic Container Service (ECS), simplifying your
development to production workflow. Amazon ECR eliminates the need to operate your own
container repositories or worry about scaling the underlying infrastructure.
Amazon ECR hosts your images in a highly available and scalable architecture, allowing you to
reliably deploy containers for your applications.
Integration with AWS Identity and Access Management (IAM) provides resource-level control of
each repository. With Amazon ECR, there are no upfront fees or commitments. You pay only
for the amount of data you store in your repositories and data transferred to the Internet.
This activity guide cover steps for:
1. Pushing Images to Amazon ECR
a. Creating a Repository in ECR
b. Configure AWS credentials and Install Docker
c. Creating a Dockerfile and build Images from it
d. Pushing images to Repository
2. Deleting/Cleanup

3 PRE-REQUSITE
• Note: Create account (Trial or Paid) on AWS Cloud.
Follow Activity Guide Register_for_AWS_Free_Tier_Account_And_Login_to_AWS Console_ed** from portal
• Note: In this guide we are going using Linux machine to perfrom this lab you can provision Linux machine on Amazon.
Follow Activity Guide Create_&_Connect_To_EC2_Linux_Instance_ed** from Portal to create Linux machine on AWS.
• Note: To install & configure AWS CLI, and to install EKSCTL and kubectl.
Follow guide Activity Guide: AG_Install_Configure_AWSCLI_KUBECTL_EKSCTL_on_Linux_ed** from Portal
4 CREATING REPOSITORY IN ECR
1. Open your Console and search ECR.
2. Click on Create Repository.
5 INSTALL DOCKER & CREATE IMAGE
5.1 Installing Docker On EC2 Instance
1. Login to Linux (Ubuntu) machine that you created following and Install & Configure AWSCLI Using Guide: AG_Install_and_Configure_AWSCLI_Kubectl_and_EKSCTL_on_Linux_ed1** from Portal.
2. Switch to the root user
sudo su -
3. First Update Software Repositories
$ sudo apt-get update -y
4. Install Docker
$ sudo apt install docker.io
Note: If you get message like below then type Y and hit enter
5. Start and Enable Docker
$ sudo systemctl start docker
$ sudo systemctl enable docker
6. Check Docker status
$ sudo systemctl status docker
You should see output like below (exit by typing q)
7. Check Docker Version
docker –version
You should see output like
2. Dockerfile Created.
FROM ubuntu:18.04
# Install dependencies
RUN apt-get update && \
apt-get -y install apache2
# Install apache and write hello world message
RUN echo 'Hello World!' > /var/www/html/index.html
# Configure apache
RUN echo '. /etc/apache2/envvars' > /root/run_apache.sh && \
echo 'mkdir -p /var/run/apache2' >> /root/run_apache.sh && \
echo 'mkdir -p /var/lock/apache2' >> /root/run_apache.sh && \
echo '/usr/sbin/apache2 -D FOREGROUND' >> /root/run_apache.sh && \
chmod 755 /root/run_apache.sh
EXPOSE 80
CMD /root/run_apache.sh
3. Now build the docker image from the Dockerfile.
docker build -t hello-world .
6 PUSH DOCKER IMAGE TO ECR
1. Access ECR console and click on View push commands
Note: If you get error like “Unable to locate credentials. You can configure credentials by running "aws configure". Error: Cannot perform an interactive login from a non TTY device” then make sure you follow “aws configure” from guide AG_Install_and_Configure_AWSCLI_Kubectl_and_EKSCTL_on_Linux_ed1** from Portal.
2. Copy the get-login password command and run as well copy other commands and paste.
3. Run the docker push command that you copied, and the image will start uploading to ECR
repository. First tag your image with the Amazon ECR registry, repository, and image tag name combination to use.
Note: The registry format is aws_account_id.dkr.ecr.region.amazonaws.com. The repository name should match the repository that you created for your image.
docker tag <Image_Name>:<image tag> <aws_account_id>.dkr.ecr.<region>.amazonaws.com/<repository>:<tag>
docker tag hello-world:latest 111167273292.dkr.ecr.us-east-1.amazonaws.com/ecr-demo:latest
Second Step is to push image to ECR. To push Image
docker push <aws_account_id>.dkr.ecr.<region>.amazonaws.com //<repository>:<tag>
docker push 111167273292.dkr.ecr.us-east-1.amazonaws.com/ecr-demo:latest
7 DELETING/CLEANUP
7.1 Delete the pushed image and ECR
1. Back on ECR console delete the pushed image at first.
2. Type delete and Click on Delete.
3. Select your Repository and delete it by clicking on delete.
4. Click on Delete.
