The CDN builder is used to create Azure Content Delivery Network instances.

  • CDN Profile (Microsoft.Cdn/profiles)
  • CDN Endpoint (Microsoft.Cdn/profiles/endpoints)
  • CDN Custom Domain (Microsoft.Cdn/profiles/endpoints/customDomains)

There are three builders available:

  • The CDN builder, which maps to a CDN profile.
  • The Endpoint builder, which creates endpoints and custom domains. Endpoints are created within a CDN.
  • The CDN Rule builder, which creates CDN rules with conditions and actions that can be added to an endpoint

let isaacWebApp = webApp {

let isaacStorage = storageAccount {
    name "isaacsuperstore"

let isaacRule = cdnRule {
    name "isaacsuperrule"
    order 1
    when_request_header "issac" Contains ["great"] ToLowercase
    modify_response_header Append "issac" "super"

let isaacCdn = cdn {
    name "isaacsupercdn"
    add_endpoints [
        endpoint {
            origin isaacStorage
            optimise_for Cdn.OptimizationType.LargeFileDownload
        endpoint {
            origin isaacWebApp
