💡 [REQUEST] - output kubeconfig file for use

[johncosta]

Summary

Limitation
In version 0.0.3, if a user of the module wants to access the kubeconfig, there's some overhead they will need.

First, they'll need to create a local sensitive file.

resource "local_sensitive_file" "kubeconfig" {
  content  = module.k8s.cluster_kube_config.0.raw_config
  filename = "/full/path/to/.kube/${module.k8s.cluster_name}-config.yml"
}

Second, they'll need to output the values for use.

output "cluster_kubeconfig_path" {
  value = local_sensitive_file.kubeconfig.filename
}

output "cluster_kubeconfig_path_export" {
  value = "export KUBECONFIG=${local_sensitive_file.kubeconfig.filename}"
}

Value Statement
As a developer, I would like the kubeconfig file written to a specified directory and a convenience value for setting the KUBECONFIG environment variable.

Basic Example

module "k8s" {
  source  = "johncosta/kubernetes/digitalocean"
  version = "0.0.3"

  # cluster configuration
  cluster_name_prefix          = local.cluster_name_prefix
  cluster_region               = "nyc1"

  # convenience configuration
  path_to_kubeconfig      = "/Users/jcosta/.kube/"               # <--- new variable
  kubeconfig_filename    = "custom-name-of-config.yml" # <--- new variable
}

1. a value of null (or unset) or "" will not write out the kubeconfig file
2. setting the value will result in two additional outputs becoming available, cluster_kubeconfig_path which will be the full path to the kubeconfig file that includes the output filename, and cluster_kubeconfig_path_export which is a string value that can be cut and paste into one's environment to inform kubectl of the location.

Drawbacks

This is an initial representation of these values so there might be conditions that are unforseen.
