allow an entity to: log into ecr and push images intp a specific repo, then create/update a task-definition, and then create/update a service in a specific ecs cluster
# place into .github/workflows/aws
# This workflow will build and push a new container image to Amazon ECR,
# and then will deploy a new task definition to Amazon ECS, on every push
# to the master branch.
#
# To use this workflow, you will need to complete the following set-up steps:
#
# 1. Create an ECR repository to store your images.
# For example: `aws ecr create-repository --repository-name my-ecr-repo --region us-east-2`.
# Replace the value of `ECR_REPOSITORY` in the workflow below with your repository's name.
