How to purge cache in azure cdn

Question

How to purge cache in azure cdn

Rishabh 20

Dear Team,

I am seeking assistance regarding an essential task I'm facing challenges with. Specifically, I've been endeavouring to clear the Azure CDN cache using the az cli utility. However, attempts to execute the following commands:

az cdn endpoint purge -g group -n endpoint --profile-name profile-name --content-paths '/*'
az cdn endpoint purge --resource-group $rg_name --profile-name $profile_name --name $name --no-wait --content-paths '/*' --verbose

have resulted in encountering an error message: "Endpoint(s) not found. Please verify the resource(s), group, or its parent resources exist."

At this juncture, uncertainty prevails as to whether the command itself is incorrect or if there are inherent limitations hindering the cache clearance via this specified method. I wish to highlight that our Azure CDN Service operates under the Standard pricing tier, and my az-cli version stands at 2.0.81.

I would highly appreciate your guidance on this matter or any alternative approaches you might suggest to effectively clear the CDN cache.

Your timely assistance in resolving this matter would be immensely valuable.

Thank you for your attention and support.

Best regards,
Rishabh Sharma

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to purge the contents of CDN using Azure CLI.

The command is correct.

I just did a lab and I was able to get the query running. (first one)

The error looks like you have mentioned a endpoint that does not exist.

Can you please make sure you are giving the correct EndPoint Name, Profile Name and RG name in the command?

Please make sure you are using the latest Az CLI version

or use Azure Cloud Shell CLI to test it.

Cheers,

Kapil

Thank you, @KapilAnanth-MSFT for your quick reply.
In my case, the profile name and the endpoint name, both the same.

Can you please check the attached screenshot and let me know if I'm doing anything incorrectly?
I'm using the profile name and endpoint name as cdn in the above commands.

@Rishabh

Looking at the screenshot,

The command should be

az cdn endpoint purge -g <YOURRGNAME> -n afd --profile-name afd --content-paths '/'*

@KapilAnanth-MSFT , No luck.
If I'm using the provided command, the error is still the same.
Endpoint(s) not found. Please verify the resource(s), group or its parent resources exist.

Are you logged in to the correct subscription/tenant?

Follow this to set the subscription where the CDN actually resides : Change the active subscription.

Please run the following and share the results. (check if the CDN and EndPoints are listing)

1.

az cdn profile list -g <RGName>

See if the CDN profile is displayed or not

If 1 was successful, go ahead and run

az cdn endpoint list -g <RGName> --profile-name <ProfileNameFromAbove>

And see if the CDN EndPoint is displayed or not.

Share the results of 1 and 2.

Hello Kapil,

The first command, 'az cdn profile list -g <RGName>', provided detailed output for both CDN profiles. But, when I ran the second command, 'az cdn endpoint list -g <RGName> --profile-name <ProfileNameFromAbove>', it returned an empty output '[]'.

I need your help with this. Thanks!"

@Rishabh

That means the CDN does not have any endpoints in it.

Can you share the screenshot of "Overview" section of your CDN.

Like the below,

Hello @KapilAnanth-MSFT

I've attached the required screenshot from the overview section. There's one endpoint that is bound to our domain, and the domain is working fine.

Please let me know if you need any further details.

It appears you are using an Azure Front Door and not a CDN.

In that case, the command becomes,

az afd endpoint purge -g <group> --profile-name <profile> --endpoint-name <endpoint> --content-paths '/*'

Refer : Cache purging in Azure Front Door with Azure CLI

Please let me know if this works.

Yes,
I've also run the above command, but unfortunately, the command is saying afd is not in the 'az' command group.

az afd endpoint purge -g <rg> --profile-name <profile-name> --endpoint-name <###azurefd.net> --content-paths '/*' az: 'afd' is not in the 'az' command group. See 'az --help'. If the command is from an extension, please make sure the corresponding extension is installed. To learn more about extensions, please visit https://docs.microsoft.com/en-us/cli/azure/azure-cli-extensions-overview The most similar choice to 'afd' is: ad

After investigating further I found this -
Command group 'afd' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus

@Rishabh

That is correct, the "az afd" is in preview.

Please use "az upgrade" to get the latest version.

@Rishabh

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I understand that you would like to purge the contents of CDN using Azure CLI.

After further investigation, we found that the resource was actually an AFD and not a CDN.

In that case, the command becomes,

az afd endpoint purge -g <group> --profile-name <profile> --endpoint-name <endpoint> --content-paths '/*'

Refer : Cache purging in Azure Front Door with Azure CLI

NOTE:

The "az afd" is in preview
Please use "az upgrade" to get the latest version.
