How do I add CDN Edge Groups to a Bucket?
Navigate to 'Bucket' -> 'Access Control', click on the graph icon 'Show All' button, and scroll to the section of 'Limits for Edge groups'.
Click the button 'Add New Edge Group', a window will pop up. Select the CDN Edge Group and click 'Save'. You may add multiple CDN Edge Groups into a Bucket. Once edge groups are added into user's Bucket, user would be able to select the CDN edge group upon CDN resource creation.
Multiple edge groups can be added into one Bucket.
