Amazon ECS "Render Task Definition" Action for GitHub Actions

Inserts a container image URI and optionally given environment variables into an Amazon ECS task definition JSON file, creating a new task definition file.

Usage

To insert the image URI bluemaex/amazon-ecs-sample:latest as the image for the web container in the task definition file, and then deploy the edited task definition file to ECS:

To add environment variables to you container definition you can add them to the job or step environment like seen below. You have to prefix them with TASK_ to avoid leaking secrets and adding unecessary variables. An env var like TASK_APP_NAME will be passed as APP_NAME to the container definition.
