Hello jigyasu mishra!

How are you creating the AKS cluster? Also how do you create the service principal? (Portal, CLI, ARM etc.)

Please share these details, for example, if using command, could you please share the command used to create the AKS cluster and service principal?

Please make sure to avoid sending confidential information here.

Hello jigyasu mishra

The clientId you are using "\te6379e6b-7428-4063-8df4-dbf793b15da6" seems invalid.

I just created a service principal and the appId has 36 characters and no "". Even if we exclude "" from your Id, it still has 37 characters. If there is any particularity for Terraform, I am not aware of.

I would recommend you make sure the appId / clientId is valid. You may go to Azure Portal -> App registrations and try to identify it there.

Additionally, you may want to create the AKS cluster using Azure CLI. For example:

az aks create -g aks-rg -n aks --service-principal <appId> --client-secret <secret>

I hope this is helpful. If any clarification needed, let me know and I will do my best to answer.

I just created a service principal and the appId has 36 characters and no but when i run the terraform apply command then it take automatically starting word "t". I also checked my azure directory appid and secret was correct and also given the permission as contributor role.

Unfortunately I don't have Terraform expertise. As an workaround, I would suggest you to use Azure CLI to create the cluster or wait maybe someone else can provide another suggestion on this thread.

@jigyasu mishra according to https://developer.hashicorp.com/terraform/tutorials/kubernetes/aks the service principal and secret values should be declared in variables.tf file and then defined in terraform.tfvars file. It would be worth checking those files and see if you are mistakenly appending the "t" letter.
