Modular Kubernetes Cluster for GCE.

Usage

le "k8s" {
urce      = "github.com/GoogleCloudPlatform/terraform-google-k8s-gce"
me        = "dev"
twork     = "k8s"
gion      = "${var.region}"
ne        = "${var.zone}"
s_version = "1.8.1"
m_nodes   = "${var.num_nodes}"

Input variables

• name (required): The name of the kubernetes cluster. Note that nodes names will be prefixed with k8s-.
• k8s_version (optional): The version of kubernetes to use. See available versions using: apt-cache madison kubelet. Default is 1.7.3
• cni_version (optional): The version of the kubernetes cni resources to install. See available versions using: apt-cache madison kubernetes-cni. Default is 0.5.1.
• docker_version (optional): The version of Docker to install. See available versions using: apt-cache madison docker-ce. Default is 17.06.0
• dashboard_version (optional): The version tag of the kubernetes dashboard, per the tags in the repo: https://github.com/kubernetes/dashboard. Default is v1.6.3.
• compute_image (optional): The project/image to use on the master and nodes. Must be ubuntu or debian 8+ compatible. Default is ubuntu-os-cloud/ubuntu-1704.
• network (optional): The network to deploy to. Default is default.
• subnetwork (optional): The subnetwork to deploy to. Default is default.
