Kubernetes(Single Master)

This module deploys single-master Kubernetes cluster to SAKURA Cloud using kubeadm.

This project is for develop environment, so please do not use this in production

Overview

Getting Started

Prerequisites

• Terraform
• Terraform for SAKURA Cloud(community provider)
• (Optional) SAKURA Cloud CLI usacloud

Customize the deployment

Customizations to the base installation are made to the Terraform variables for each deployment.
Examples of variables are provided in the file examples/kubernetes.tf.

Initialize and configure Terraform

Get Terraform's SAKURA Cloud modules and providers

Get the modules and providers that Terraform will use to create the cluster resources:

$ terraform init

Deploy the cluster

Test the blueprint before deploying:

$ terraform plan

Next, deploy the cluster:

$ terraform apply

This should run for a short time, and when complete, the cluster should be ready.

Access the cluster

Access to nodes with ssh

Nodes credentials are written beneath the certs/ directory. You can use this to access the cluster by ssh.

$ usacloud server ssh -i certs/id_rsa <your-node-name>

Using kubectl

To use kubectl command on the local machine, you need to download the kubeconfig file as follows:

$ usacloud server scp -i certs/id_rsa <your-master-node-name>:/etc/kubernetes/admin.conf ./admin.conf
$ export KUBECONFIG=$(pwd)/admin.conf
$ kubectl cluster-info
