| # This workflow will build and push a new container image to Amazon ECR, | |
| # and then will deploy a new task definition to Amazon ECS, when there is a 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 the `ECR_REPOSITORY` environment variable in the workflow below with your repository's name. | |
| # Replace the value of the `AWS_REGION` environment variable in the workflow below with your repository's region. | |
| # | |
| # 2. Create an ECS task definition, an ECS cluster, and an ECS service. | |
| # For example, follow the Getting Started guide on the ECS console: | |
| # https://us-east-2.console.aws.amazon.com/ecs/home?region=us-east-2#/firstRun | |
| # Replace the value of the `ECS_SERVICE` environment variable in the workflow below with the name you set for the Amazon ECS service. | |
| # Replace the value of the `ECS_CLUSTER` environment variable in the workflow below with the name you set for the cluster. | |
| # | |
| # 3. Store your ECS task definition as a JSON file in your repository. | |
| # The format should follow the output of `aws ecs register-task-definition --generate-cli-skeleton`. | |
| # Replace the value of the `ECS_TASK_DEFINITION` environment variable in the workflow below with the path to the JSON file. | |
| # Replace the value of the `CONTAINER_NAME` environment variable in the workflow below with the name of the container | |
| # in the `containerDefinitions` section of the task definition. | |
| # | |
| # 4. Store an IAM user access key in GitHub Actions secrets named `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`. | |
| # See the documentation for each action used below for the recommended IAM policies for this IAM user, | |
| # and best practices on handling the access key credentials. | |
