Serving files from OpenStack Object Storage ("Swift")

imgproxy can process images from OpenStack Object Storage, also known as Swift. To use this feature, do the following:

1. Set the IMGPROXY_USE_SWIFT environment variable to true

2. Configure Swift authentication with the following environment variables

   • IMGPROXY_SWIFT_USERNAME: the username for Swift API access. Default: blank
   • IMGPROXY_SWIFT_API_KEY: the API key for Swift API access. Default: blank
   • IMGPROXY_SWIFT_AUTH_URL: the Swift Auth URL. Default: blank
   • IMGPROXY_SWIFT_AUTH_VERSION: the Swift auth version, set to 1, 2 or 3 or leave at 0 for autodetect.
   • IMGPROXY_SWIFT_TENANT: the tenant name (optional, v2 auth only). Default: blank
   • IMGPROXY_SWIFT_DOMAIN: the Swift domain name (optional, v3 auth only): Default: blank

3. Use swift://%{container}/%{object_path} as the source image URL, e.g. an original object storage URL in the format of /v1/{account}/{container}/{object_path}, such as http://127.0.0.1:8080/v1/AUTH_test/images/flowers/rose.jpg, should be converted to swift://images/flowers/rose.jpg.
