Generic Configuration to use CDN in OMN
In order to work on the OMN System with the AWS CDN Standard a configuration set consisting out of groups/subsgroups and key value pairs are delivered with the system in Generic Configuration. These parameters need to be available in the configuration, so that the CDN delivery service will work.
The parameters will be created automatically by the system via property (cdn.aws.enabled).
The key value pairs supplied are explained in more detail below:
| Key | Value description |
|---|---|
aws_cdn_api_endpoint |
Contains configurations for the API endpoint URL for the storage/update and deletion of data in the CDN bucket by OMN. |
aws_cdn_api_secret |
Contains secret which is needed to authenticate in the CDN API. |
aws_cdn_fallback_image |
Contains the OMN TID of the fallback image that is to be used by the Lambda service if the asset referenced in the CDN-URL with OMN TID cannot be delivered. There will only be one global fallback image in future (see section General CDN parameterisation). The global fallback image should also be played for images, PDFs and videos. |
|
Many runtime parameters relating to Lambda and CDN are already set during deployment and cannot be changed at
runtime. Only the fallback image can be changed at runtime, as a separate API function is available for this. A complete list of all Lambda parameters can be found here. |
