Terraform Kubernetes Provider

The kubernetes_cron_job resource allows you to create and manage Kubernetes CronJobs, which execute Jobs on a time-based schedule. Each CronJob object functions similarly to a line in a crontab file, running a job periodically based on a schedule written in Cron format.

Important Considerations:

• Timezone: All schedule times are based on the timezone of the Kubernetes master node where the job is initiated.
• API Version Migration: For Kubernetes v1.25 and later, the batch/v1beta1 API has been removed. You should migrate to the batch/v1 API as per the Kubernetes migration guides.

The kubernetes_horizontal_pod_autoscaler_v1 resource automatically scales the number of pods in a replication controller, deployment, or replica set based on observed CPU utilization.

To use this resource, you must define a metadata block for identification and a spec block to define the scaling behavior and the target resource being scaled.

resource "kubernetes_horizontal_pod_autoscaler_v1" "example" {
  metadata {
    name = "terraform-example"
  }

  spec {
    max_replicas = 10
    min_replicas = 8

    scale_target_ref {
      kind = "Deployment"
      name = "MyApp"
    }
  }
}

The kubernetes_ingress_class resource allows you to define an IngressClass in Kubernetes. Ingresses use these classes to reference a specific controller and its configuration. This allows multiple controllers to coexist in a cluster, where each Ingress specifies which class it should use to be implemented.

resource "kubernetes_ingress_class" "example" {
  metadata {
    name = "example"
  }

  spec {
    controller = "example.com/ingress-controller"
    parameters {
      api_group = "k8s.example.com"
      kind      = "IngressParameters"
      name      = "external-lb"
    }
  }
}
