Configure AWS credential environment variables for use in other GitHub Actions.

"Configure AWS Credentials" Action For GitHub Actions

Configure AWS credential and region environment variables for use in other GitHub Actions. The environment variables will be detected by both the AWS SDKs and the AWS CLI to determine the credentials and region to use for AWS API calls.

Usage

Add the following step to your workflow:

    - name: Configure AWS Credentials
      uses: aws-actions/configure-aws-credentials@v1
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: us-east-2

For example, you can use this action with the AWS CLI available in GitHub's hosted virtual environments.

jobs:
  deploy:
    name: Upload to Amazon S3
    runs-on: ubuntu-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Configure AWS credentials
      uses: aws-actions/configure-aws-credentials@v1
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: us-east-2

    - name: Copy files to S3 with the AWS CLI
      run: |
        aws s3 sync . s3://my-s3-website-bucket

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

Credentials

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.
• Rotate the credentials used in GitHub Actions workflows regularly.
• Monitor the activity of the credentials used in GitHub Actions workflows.

Assuming a role

If you would like to use the credentials you provide to this action to assume a role, you can do so by specifying the role ARN in role-to-assume. The role credentials will then be output instead of the ones you have provided. The default session duration is 6 hours, but if you would like to adjust this you can pass a duration to role-duration-seconds.

Example:

    - name: Configure AWS Credentials
      uses: aws-actions/configure-aws-credentials@v1
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: us-east-2
        role-to-assume: arn:aws:iam::123456789100:role/role-to-assume
        role-duration-seconds: 1200

Session tagging

The session will have the name "GitHubActions" and be tagged with the following tags: (GITHUB_ environment variable definitions can be found here)

Key	Value
GitHub	"Actions"
Repository	GITHUB_REPOSITORY
Workflow	GITHUB_WORKFLOW
Action	GITHUB_ACTION
Actor	GITHUB_ACTOR
Branch	GITHUB_REF
Commit	GITHUB_SHA

Note: all tag values must conform to the requirements. Particularly, GITHUB_WORKFLOW will be truncated if it's too long. If GITHUB_ACTOR or GITHUB_WORKFLOW contain invalid charcters, the characters will be replaced with an '*'.
