terraform-exoscale-sks

A terraform module to create a managed Kubernetes cluster on Exoscale SKS.

This module creates an SKS cluster with one or more node pools. It creates one security group for all instances with the minimum rules recommended in the exoscale documentation. It also creates one anti-affinity group for each node pool. It then automatically retrieves the kubeconfig that allows access to the cluster.

Usage example

module "sks" {
  source  = "camptocamp/sks/exoscale"
  version = "0.3.1"

  name = "test"
  zone = "de-fra-1"

  kubernetes_version = "1.21.3"

  nodepools = {
    "router" = {
      instance_type = "standard.medium"
      size          = 2
    },
    "compute" = {
      instance_type = "standard.small"
      size          = 3
    }
  }
}

terraform-exoscale-sks's Issues

Using this module to provision several clusters ?

Thanks a lot for this module, really useful.
This is more a question than an issue: is it planned to provide the foreach or count properties to generate several clusters using this same module ?

Cannot create cluster with 1.20.2

Hello,
running the module with the default 1.20.2 raises an error:

Error: Post "https://api-de-fra-1.exoscale.com/v2.alpha/sks-cluster": invalid request: Invalid Kubernetes version 1.20.2. Available versions are: 1.20.5

There is no problem with 1.20.5 though

module "sks" {
  source  = "camptocamp/sks/exoscale"
  version = "0.3.1"
  kubernetes_version = "1.20.5"

  name = "test"
  zone = "de-fra-1"

  nodepools = {
    "router" = {
      instance_type = "medium"
      size          = 2
    },
    "compute" = {
      instance_type = "small"
      size          = 3
    },
  }
}

Cannot add labels to nodepools

Hi,

when trying to add labels to my nodepools, I get an error:

│ Error: Invalid value for input variable
│ 
│   on main.tf line 10, in module "sks":
│   10:   nodepools = {
│   11:     "longhorn" = {
│   12:       description = "Longhorn Nodes, not to be autoscaled"
│   13:       disk_size = "1000"
│   14:       instance_type = "standard.small"
│   15:       size          = 2
│   16:       labels = {
│   17:         "node.longhorn.io/create-default-disk" = "true"
│   18:       }
│   19:     },
│   20:     "compute" = {
│   21:       instance_type = "standard.medium"
│   22:       size          = 1
│   23:     },
│   24:   }
│ 
│ The given value is not suitable for module.sks.var.nodepools declared at .terraform/modules/sks/variables.tf:16,1-21: all map elements must have the same type.

This is due to the variable definition here, which doesn't work for mixed types:

variable "nodepools" {
  description = "The SKS node pools to create."
  type        = map(any)
}

My terraform code:

module "sks" {
  source  = "camptocamp/sks/exoscale"
  version = "0.3.1"

  name = "default"
  zone = "de-fra-1"
  kubernetes_version = "1.24.1"

  nodepools = {
    "longhorn" = {
      description = "Longhorn Nodes, not to be autoscaled"
      disk_size = "1000"
      instance_type = "standard.small"
      size          = 2
      labels = {
        "node.longhorn.io/create-default-disk" = "true"
      }
    },
    "compute" = {
      instance_type = "standard.medium"
      size          = 1
    },
  }
}
