Azure CDN not updating after deployment – Azure

Hey everyone,

I’ve setup a deployment pipeline for the JellyWidgets.com react app that I’m currently messing around on. Unfortunately, while the deployment appeared to be successful it the CDN wasn’t updating.

This turned out to be a fairly simply fix – I needed to purge the cache after each deployment. This can be done manually using the Azure portal:

Simply click the purge button on your CDN’s profile page. For a more permanent fix you can also setup a pipeline step like the following:

      - task: AzureCLI@2
        displayName: 'Purge the CDN.'
        inputs:
          azureSubscription: $(azureSubscription)
          scriptType: 'pscore'
          scriptLocation: 'inlineScript'
          inlineScript: 'az cdn endpoint purge --resource-group widgets-prod --name $(resourceGroup) --profile-name JellyWidgets --content-paths "/*" --no-wait'
          workingDirectory: '$(Build.SourcesDirectory)/UI/infrastructure'
          failOnStandardError: true

Note that if you don’t add the “no-wait” step it can take a long time for the purge to complete.
