CNCF supported k8s OSS distributions

Located: https://github.com/kubernetes repositories

Described: https://github.com/kubernetes/community/blob/master/sig-cluster-lifecycle/README.md#subprojects

• bootkube - tool for launching self-hosted Kubernetes clusters 
• kops - run production-grade, highly available, k8s clusters on AWS, GCE or DigitalOcean
• kube-aws - create, update and destroy Kubernetes clusters on AWS, Highly available and scalable k8s clusters backed by multi-AZ deployment and Node Pools
• kube-up - start k8s in GCE, part of Kubernetes
• kubeadm - toolkit that helps you bootstrap a best-practice Kubernetes cluster in an easy, reasonably secure and extensible way, part of Kubernetes
• kubernetes-anywhere - k8s in the cloud
• kubespray - create HA cluster on AWS, GCE, Azure, OpenStack, vSphere or Baremetal
• minikube -  run Kubernetes locally, single-node k8s cluster inside a VM/Docker

How to start with Kubernetes

Use your own laptop...

• Minikube - single node, easy, can be docker based (--vm-driver=none) or virtualization needed, addons, mount local dir to pods
• Kubeadm - official Kubernetes tool for installations, multinode, multi distro
• Kubespray - multinode, more complex, many options, HA, enterprise, multi distro

Use Public Cloud...

Many Public Cloud providers has "Kubernetes as a Service", depends on costs...

• https://github.com/kubernetes-incubator/kubespray
• Started by a group of independent developers as "Kargo" project
• Install Production Ready Kubernetes Cluster with HA
• Ansible based
• Kubernetes Incubated project
• Supported distributions: Container Linux by CoreOS, Debian, Ubuntu, CentOS/RHEL 7, Fedora/CentOS Atomic, openSUSE Leap 42.3/Tumbleweed
• Network Plugins: flannel, calico, canal, cilium, contiv, weave
• Many options: https://github.com/kubernetes-incubator/kubespray/tree/master/inventory/sample/group_vars

3 VMs, all 3 have etcd installed, all 3 are nodes (running pods), 2 of them run master components

kubeadm

• https://kubernetes.io/blog/2016/09/how-we-made-kubernetes-easy-to-install/

• part of the Kubernetes distribution as of 1.4.0

• response to criticisms of Kubernetes is hard to install

• does not provision machines

• https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/

• You install Docker and the official Kubernetes packages

• Select a master host, run kubeadm init

• This sets up the control plane and outputs a kubeadm join […] command which includes a secure token

• On each host selected to be a worker node, run the kubeadm join […] command from above

• Install a pod network
