List down all namespaces in minikube using Terraform

Question

Hi Guys,

I am new to the Terraform platform. I want to list down all the namespaces available in the Minikube cluster using Terraform. How can I do that?

Hi@akhtar,

You can use data source in Terraform. This data source provides a mechanism for listing the names of all available namespaces in a Kubernetes cluster. You can also go through the below code.

provider "kubernetes" {
  config_context_cluster   = "minikube"
}
data "kubernetes_all_namespaces" "allns" {}
output "all-ns" {
  value = data.kubernetes_all_namespaces.allns.namespaces
}

Execute this code in your terraform platform, you will get your output.

C:\Users\NADIM AKTHAR\Desktop\terraform\kuberenetes>terraform apply
data.kubernetes_all_namespaces.allns: Refreshing state...
kubernetes_namespace.example: Refreshing state... [id=my-first-namespace]
Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
Outputs:
all-ns = [
  "default",
  "kube-node-lease",
  "kube-public",
  "kube-system",
  "my-first-namespace",
]
