Kubernetes can run on various platforms: from your laptop, to VMs on a cloud provider, to a rack of bare metal servers. The effort required to set up a cluster varies from running a single command to crafting your own customized cluster. Use this guide to choose a solution that fits your needs.

If you just want to “kick the tires” on Kubernetes, use the local Docker-based solutions.

When you are ready to scale up to more machines and higher availability, a hosted solution is the easiest to create and maintain.

Turnkey cloud solutions require only a few commands to create and cover a wide range of cloud providers. On-Premises turnkey cloud solutions have the simplicity of the turnkey cloud solution combined with the security of your own private network.

If you already have a way to configure hosting resources, use kubeadm to easily bring up a cluster with a single command per machine.

Custom solutions vary from step-by-step instructions to general advice for setting up a Kubernetes cluster from scratch.

Minikube is a method for creating a local, single-node Kubernetes cluster for development and testing. Setup is completely automated and doesn’t require a cloud provider account.
microk8s provides a single command installation of the latest Kubernetes release on a local machine for development and testing. Setup is quick, fast (~30 sec) and supports many plugins including Istio with a single command.
IBM Cloud Private-CE (Community Edition) can use VirtualBox on your machine to deploy Kubernetes to one or more VMs for development and test scenarios. Scales to full multi-node cluster.
IBM Cloud Private-CE (Community Edition) on Linux Containers is a Terraform/Packer/BASH based Infrastructure as Code (IaC) scripts to create a seven node (1 Boot, 1 Master, 1 Management, 1 Proxy and 3 Workers) LXD cluster on Linux Host.
Kubeadm-dind is a multi-node (while minikube is single-node) Kubernetes cluster which only requires a docker daemon. It uses docker-in-docker technique to spawn the Kubernetes cluster.
Ubuntu on LXD supports a nine-instance deployment on localhost.

すぐに利用できるクラウドを使ったソリューション

These solutions allow you to create Kubernetes clusters on a range of Cloud IaaS providers with only a few commands. These solutions are actively developed and have active community support.

すぐに利用できるオンプレミスを使ったソリューション

These solutions allow you to create Kubernetes clusters on your internal, secure, cloud network with only a few commands.

カスタムソリューション

Kubernetes can run on a wide range of Cloud providers and bare-metal environments, and with many base operating systems.

If you can find a guide below that matches your needs, use it. It may be a little out of date, but it will be easier than starting from scratch. If you do want to start from scratch, either because you have special requirements, or just because you want to understand what is underneath a Kubernetes cluster, try the Getting Started from Scratch guide.

If you are interested in supporting Kubernetes on a new platform, see Writing a Getting Started Guide.

If you already have a way to configure hosting resources, use kubeadm to easily bring up a cluster with a single command per machine.

カラムの定義

IaaS Provider is the product or organization which provides the virtual or physical machines (nodes) that Kubernetes runs on.
OS is the base operating system of the nodes.
Config. Mgmt. is the configuration management system that helps install and maintain Kubernetes on the nodes.
Networking is what implements the networking model. Those with networking type none may not support more than a single node, or may support multiple VM nodes in a single physical node.
Conformance indicates whether a cluster created with this configuration has passed the project’s conformance tests for supporting the API and base features of Kubernetes v1.0.0.
Support Levels
- Project: Kubernetes committers regularly use this configuration, so it usually works with the latest release of Kubernetes.
- Commercial: A commercial offering with its own support arrangements.
- Community: Actively supported by community contributions. May not work with recent releases of Kubernetes.
- Inactive: Not actively maintained. Not recommended for first-time Kubernetes users, and may be removed.
Notes has other relevant information, such as the version of Kubernetes used.
