GKE: Ocean

Ocean GKE

This post demonstrates how to create an Ocean Cluster by importing an existing GKE cluster using the Spotinst Terraform V2 plugin.

This post assumes that you already have a Spotinst account and went through Spotinst Terraform Installation.

Creating a GKE Ocean Cluster

 

Example Usage – Creating a GKE Ocean Import resource – Basic Example

resource "spotinst_ocean_gke_import" "example" {

  cluster_name = "example-cluster-name"
  location     = "us-central1-a"
  
  whitelist = ["n1-standard-1", "n1-standard-2"]
  
  backend_services = [{
      service_name  = "example-backend-service"
      location_type = "regional"
      scheme        = "INTERNAL"
      named_ports = {
        name  = "http"
        ports = [80, 8080]
      }
  }]
}

Parameters

• cluster_name – (Required) The group name.
• location – (Required) The maximum number of instances the group should have at any time.
• whitelist – (Required) the list of instance types to be used by Ocean when provisioning new instances.
• backend_services – (Required) The minimum number of instances the group should have at any time.
  • service_name – (Required) The name of the backend service.
  • location_type – (Optional) Sets which location the backend services will be active. Valid values: regional, global.
  • scheme – (Optional) Use when location_type is regional. Set the traffic for the backend service to either between the instances in the VPC, or to traffic from the internet. Valid values: INTERNAL, EXTERNAL.
  • named_port – (Optional) Describes a named port and a list of ports.
    • port_name – (Required) The name of the port.
    • ports – (Required) A list of ports.

Example Usage – Creating a custom GKE Ocean Launch Specification

Provides a custom Spotinst Ocean GKE Launch Spec resource.

resource "spotinst_ocean_gke_launch_spec" "example" {
  ocean_id     = "o-123456"
  source_image = "image"
  
  metadata = [{
      key   = "gci-update-strategy"
      value = "update_disabled"
  }]
  
  labels = [{
   key   = "labelKey"
   value = "labelVal"
  }]
  
  taints = [{
   key    = "taintKey"
   value  = "taintVal"
   effect = "taintEffect"
  }]
}

Parameters

• ocean_id – (Required) The ID of the Ocean cluster in which the launchSpec is to be created.
• source_image – (Required) Image URL.
• metadata – (Required) launchSpec’s metadata.
• labels – (Optional) Set labels for the custom launchSpec.
• taints – (Optional) launchSpec’s taints.

Example Usage – Creating a GKE Ocean Launch Specification Import

Provides a custom Spotinst Ocean GKE Launch Specification Import resource. Used to import an existing node pool into a Launch Specification of an existing Ocean cluster.

resource "spotinst_ocean_gke_launch_spec_import" "example" {
  ocean_id        = "o-123456"
  node_pool_name  = "default-pool"
}

 

Parameters

• ocean_id – (Required) The ID of the Ocean cluster in which the launchSpec is to be created.
• node_pool_name – (Required) The node pool to be imported.
