Debug Output

~ resource "azurerm_kubernetes_cluster" "cluster" {
        ...redacted...
        kube_admin_config               = []
        kube_config                     = [
            {
                client_certificate     = "redacted"
                client_key             = "redacted"

                username               = "redacted"
            },
        ]
        kube_config_raw                 = (sensitive value)
        kubernetes_version              = "1.15.7"
        ...redacted...
        service_principal {
            client_id     = "redacted"
            client_secret = (sensitive value)
        }
    }

Expected Behavior

In case of in-place updates, sensitive data like the kubecfg.client_key gets redacted and is not visible in the logs.

Actual Behavior

In case of in-place updates, sensitive data like the kubecfg.client_key gets printed in clear text into the logs.

Steps to Reproduce

Change a property that causes an in-place update of the AKS cluster and run a terraform plan

Thanks for opening this issue.

This issue needs to be fixed in the Terraform Plugin SDK, as such rather than tracking this issue in multiple places I'm going to close this issue in favour of the upstream issue. Once that's been fixed we'll update the version of the Plugin SDK being used and this should get resolved - as such please subscribe to the upstream issue for updates.

Thanks!
