When it comes to identifying a process to deliver continuous value to customers, CI-CD is the defacto standard. And container technology enables that by encapsulating an application and its dependencies into a package that can be hosted and scaled independently of other applications. So DevOps engineers and application developers merged these ideas to forge a concept to create a CI-CD process to deploy containers.

At a high level, a typical CI-CD cycle involving containers comprises the following steps:
Step 1: create the application code (or an executable depending on the technology) that will be hosted in a container by a specific cloud provider.
Step 2: create and tag a docker image that contains the application (or executable) and all dependencies.
Step 3: upload the docker image into an image repository, and
Step 4: create a container out of the image that is stored in the image repository

In this GitHub repository you will find all the information required to create your own CI-CD process using Azure DevOps to push a docker image into an Amazon ECR repository.

There are a couple of pre-requisites to this process - an IAM user with permission to push images to the Amazon ECR image repository and the image repository to host the image.

Ensure that the IAM user whose credentials are being used in this configuration has permission to create and manage all the resources that are included in this repository. I have the policy file in the location \iam-policy\iam-policy.json that can be associated with the IAM user. Please update the $(aws_account_number) in the policy file before creating an IAM policy.
Create an Azure DevOps Library variable group and store App-One.AccessKey, App-One.SecretKey, and aws_account_number securely. To read how to do that, refer to my note - Manage secure variables with Azure DevOps Library and Azure Pipelines.

For more details, refer to my note: Push Docker images to Amazon ECR using Azure Pipelines and AWS Tools for PowerShell.
