Invalidating Cloudfront Cache

As part of any deployment to websites hosted behind Amazon Cloudfront, it's useful to invalidate cache right after deployment to eliminate any cache issues. This can be accomplished with a simple job:

aws_params: &aws_params
  AWS_ACCESS_KEY_ID: ((aws_access))
  AWS_SECRET_ACCESS_KEY: ((aws_secret))
  AWS_DEFAULT_REGION: us-west-2

jobs:
  - name: invalidate-cache
    plan:
    - task: cloudfront-invalidate
      config:
        platform: linux
        image_resource:
          type: docker-image
          source:
            repository: oozie/vmware-aws
        params:
          <<: *aws_params
        run:
          path: /bin/bash
          args:
          - -c
          - |
            aws cloudfront create-invalidation \
              --distribution-id E32XS6HDPKMNEI --paths "/*"
