Kubernetes Provider

The Kubernetes (K8S) provider is used to interact with the resources supported by Kubernetes. The provider needs to be configured with the proper credentials before it can be used.

Use the navigation to the left to read about the available resources.

-> Note: The Kubernetes provider is new as of Terraform 0.9. It is ready to be used but many features are still being added. If there is a Kubernetes feature missing, please report it in the GitHub repo.

Example Usage

provider "kubernetes" {
  config_context_auth_info = "ops"
  config_context_cluster = "mycluster"
}

resource "kubernetes_namespace" "example" {
  metadata {
    name = "my-first-namespace"
  }
}

Authentication

There are generally two ways to configure the Kubernetes provider.

The provider always first tries to load a config file from a given (or default) location - this requires valid config_context_auth_info & config_context_cluster.

The other way is statically define all the credentials:

provider "kubernetes" {
  host = "https://104.196.242.174"
  username = "ClusterMaster"
  password = "MindTheGap"
  client_certificate = "${file("~/.kube/client-cert.pem")}"
  client_key = "${file("~/.kube/client-key.pem")}"
  cluster_ca_certificate = "${file("~/.kube/cluster-ca-cert.pem")}"
}

If you have both valid configuration in a config file and static configuration, the static one is used as override. i.e. any static field will override its counterpart loaded from the config.

Argument Reference

The following arguments are supported:

  • host - (Optional) The hostname (in form of URI) of Kubernetes master. Can be sourced from KUBE_HOST. Defaults to https://localhost.
  • username - (Optional) The username to use for HTTP basic authentication when accessing the Kubernetes master endpoint. Can be sourced from KUBE_USER.
  • password - (Optional) The password to use for HTTP basic authentication when accessing the Kubernetes master endpoint. Can be sourced from KUBE_PASSWORD.
  • insecure- (Optional) Whether server should be accessed without verifying the TLS certificate. Can be sourced from KUBE_INSECURE. Defaults to false.
  • client_certificate - (Optional) PEM-encoded client certificate for TLS authentication. Can be sourced from KUBE_CLIENT_CERT_DATA.
  • client_key - (Optional) PEM-encoded client certificate key for TLS authentication. Can be sourced from KUBE_CLIENT_KEY_DATA.
  • cluster_ca_certificate - (Optional) PEM-encoded root certificates bundle for TLS authentication. Can be sourced from KUBE_CLUSTER_CA_CERT_DATA.
  • config_path - (Optional) Path to the kube config file. Can be sourced from KUBE_CONFIG. Defaults to ~/.kube/config.
  • config_context_auth_info - (Optional) Authentication info context of the kube config (name of the kubeconfig user, --user flag in kubectl). Can be sourced from KUBE_CTX_AUTH_INFO.
  • config_context_cluster - (Optional) Cluster context of the kube config (name of the kubeconfig cluster, --cluster flag in kubectl). Can be sourced from KUBE_CTX_CLUSTER.
