Chnage Backend Targets with Azure cli

Question

Hello,

I have application gateway and I need to change the backend targets of my rule using Azure CLI.
I have This configuration:

There will be two changes to be made at the backend level: the first one related to the url-path-map, and the second one related to the PathRules.

The first one woked with this commande:

az network application-gateway url-path-map update --resource-group "resourceGroupName" --gateway-name "gatewayName" -n "my-url-path" --default-address-pool "backend-app-maintenance" --default-http-settings "maintenance-http443"

But, I can't change the backend for my pathRules, I try some commande like that:

az network application-gateway url-path-map update --resource-group "resourceGroupName" \--gateway-name "gatewayName" -n "my-url-path" --default-address-pool "backend-app-maintenance" \--default-http-settings "maintenance-http443" \--set path_rules[0].backend_address_pool=backend-app-maintenance--set path_rules[0].backend_http_settings=maintenance-http443


Expect <class 'dict'>, got backend-app-maintenance (<class 'str'>)

Do you have any scripte or any idea to do this change ?

Regards,

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

Based on your CLI Query,

• path_rules[0].backend_address_pool should be path_rules[0].backend_address_pool.id
• path_rules[0].backend_http_settings should be path_rules[0].backend_http_settings.id
• And in both the cases, you must input the entire resource ID of the resources.

i.e.,

• backend_address_pool will have '/subscriptions/<SUBSID>/resourceGroups/<RGNAME>/providers/Microsoft.Network/<APPGWNAME>/appgw/backendAddressPools/<BACKENDPOOLNAME>'
• backend_http_settings will have '/subscriptions/<SUBSID>/resourceGroups/<RGNAME>/providers/Microsoft.Network/<APPGWNAME>/appgw/backendHttpSettingsCollection/<HTTPSETTINGSNAME>'

Of course, you can entire input the entire path or get the values of each of this and store it in a variable and pass the variable.id to the command.

Kindly let us know if this helps or you need further assistance on this issue.

Thanks,
