In my final example I'm concerned about cost (could argue for using EC2) or just experimenting for fun. The kaniko executor container in this pod will clone to code from the sample code repository, build a container image using the Dockerfile in the project, and push the built image to ECR. One of the most time-consuming factors in EC2 is selecting the appropriate server type. So on ECS, I'd be looking to do the same thing. Here developers use docker build to create a container that has the core dependencies, but when they docker run they configure a Docker volume to mount a code directory from their development host .
