This is where you define which Docker images to run, CPU/Memory, ports, commands and so on. You create these files so UFO will know to create and manage the IAM roles. It contains settings like exposed port, docker image, cpu shares, memory requirement, command to run and environmental variables. It can be thought of as an “instan… GitHub Gist: instantly share code, notes, and snippets. It easier to launch and stop container services that you need to run only at certain times. You'll need to create a service with a temporary task definition (can be done easily with CDK), and then overwrite that Task Definition with a new Task Definition.
