Deploys AWS CloudFormation Stacks.

- name: Deploy to AWS CloudFormation
  uses: aws-actions/aws-cloudformation-github-deploy@v1
  with:
    name: MyStack
    template: myStack.yaml
    parameter-overrides: "MyParam1=myValue,MyParam2=${{ secrets.MY_SECRET_VALUE }}"

The action can be passed a CloudFormation Stack name and a template file. It will create the Stack if it does not exist, or create a Change Set to update the Stack. An update fails by default when the Change Set is empty. Setting no-fail-on-empty-changeset: "1" will override this behavior and not throw an error.

See action.yml for the full documentation for this action's inputs and outputs.

This action relies on the default behavior of the AWS SDK for Javascript to determine AWS credentials and region. Use the aws-actions/configure-aws-credentials action to configure the GitHub Actions environment with environment variables containing AWS credentials and your desired region.

We recommend following Amazon IAM best practices for the AWS credentials used in GitHub Actions workflows, including:

• Do not store credentials in your repository's code. You may use GitHub Actions secrets to store credentials and redact credentials from GitHub Actions workflow logs.
• Create an individual IAM user with an access key for use in GitHub Actions workflows, preferably one per repository. Do not use the AWS account root user access key.
• Grant least privilege to the credentials used in GitHub Actions workflows. Grant only the permissions required to perform the actions in your GitHub Actions workflows. See the Permissions section below for the permissions required by this action.
• Rotate the credentials used in GitHub Actions workflows regularly.
• Monitor the activity of the credentials used in GitHub Actions workflows.

This action requires the following minimum set of permissions:

The policy above prevents the stack to be deleted by a policy for production
