Deploy an Azure Kubernetes Service (AKS) cluster using Terraform. Minor mistakes in the code.

[Dan-Zi]

Type of issue

Code doesn't work

Feedback

Please fix the following mistakes in the code examples:

Fix/Update the code:

1. jsondecode should be removed from jsondecode(azapi_resource_action.ssh_public_key_gen.output).publicKey in main.tf and ssh.tf at Implement the Terraform code section (see Problem 1 below),
   so that the resulting code would be:
   azapi_resource_action.ssh_public_key_gen.output.publicKey
2. add -raw parameter at Verify the results section
   to generate proper kubeconfig without end of stream "EOF" characters,
   so that the resulting code would be:
   echo "$(terraform output -raw kube_config)" > ./azurek8s (see Problem 2 below)

Problem 1

The description and the solution:

│ │ azapi_resource_action.ssh_public_key_gen.output is object with 2 attributes
│
│ Invalid value for "str" parameter: string required.

Problem 2

(there is a workaround in the main instruction; but it should not be done manually in fact; adding -raw parameter solves the problem)

If you see << EOT at the beginning and EOT at the end, remove these characters from the file. Otherwise, you may receive the following error message: error: error loading config file "./azurek8s": yaml: line 2: mapping values are not allowed in this context
