It is, therefore, an ideal utility for building images on AWS Fargate. DevOps engineers solve this problem using continuous delivery (CD) pipelines where developers check-in their code in a central code repository such as a Git repository, and container builds are automated using tools like Jenkins or CodePipeline. The file is then submitted to Cloud Formation which automatically deploys all the resources specified in it. Therefore, customers have two options if they want to build containers images using the traditional docker build method, while running in a container on an EC2 instance: There are inherent risks involved in both of these approaches.
