Migrating to Python 3 using Docker for your CI/CD pipeline (even if you can't use it in production)
summary
Shows a concrete path to migrate a Python 2.7 app to Python 3.7 by building and testing inside containers, then using the container as a packaging artifact to copy files out of image and install on hosts that cannot run Docker. Uses AWS CodePipeline / CodeBuild / CodeDeploy, ECR and Terraform to create VPC, subnets, ALB and an ASG with two instances. Starts with one passing test, updates requirements, and ends with a green pipeline and successful deployment, demonstrating Docker for CI/CD only and CodePipeline + CodeDeploy.
