Local Installers

• Minikube A tool that makes it easy to run Kubernetes locally inside a Linux VM. It's aimed on users who want to just test it out or use it for development. It cannot spin up a production cluster, it's a one node machine with no high availability.
  • murchie85.github.io: Installling minikube
• kind Kubernetes IN Docker - local clusters for testing Kubernetes
• store.docker.com: Docker Community Edition EDGE with kubernetes. Installing Kubernetes using the Docker Client Currently only available in Edge edition.
• medium.com: Local Kubernetes for Linux — MiniKube vs MicroK8s
• itnext.io: Run Kubernetes On Your Machine Several options to start playing with K8s in no time

Production Cluster Installers

• Kubernetes Cluster with Kops:

  • Minikube and docker client are great for local setups, but not for real clusters. Kops and kubeadm are tools to spin up a production cluster. You don't need both tools, just one of them.
  • On AWS, the best tool is kops
  • At some point AWS EKS (hosted kubernetes) will be available, at that point this will probably be the preferred option. (You won't need to maintain the masters).
  • For other installs, or if you can't get kops to work, you can use kubeadm
  • kubeadm is an alternative approach, kops is still recommended (on AWS) - you also have AWS integrations with kops automatically
  • Setup kops in your windows with virtualbox.org and vagrantup.com . Once downloaded, to type a new linux VM, just type in cmd/powershell:
  1. Spin up ubuntu via vagrant:

  C:\ubuntu> vagrant init ubuntu/xenial64
  C:\ubuntu> vagrant up
  [...]
  C:\ubuntu> vagrant ssh-config
  C:\ubuntu> vagrant ssh
  

  2. Runt kops installer:

  curl -LO https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64
  chmod +x kops-linux-amd64
  sudo mv kops-linux-amd64 /usr/local/bin/kops
  

• Kubernetes Cluster with Kubeadm It works on any deb / rpm compatible Linux OS, for example Ubuntu, Debian, RedHat or CentOS. This is the main advantage of kubeadm. The tool itself is still in beta (Q1 2018), but is expected to become stable somewhere this year. It's very easy to use and lets you spin kubernetes cluster in just a couple of minutes.

Rancher

• rancher.com Rancher is enterprise management for Kubernetes
• Rancher 2
• Rancher 2 RKE Rancher 2 that runs in docker containers. RKE is a CNCF-certified Kubernetes distribution that runs entirely within Docker containers. It solves the common frustration of installation complexity with Kubernetes by removing most host dependencies and presenting a stable path for deployment, upgrades, and rollbacks.
  • Rancher.com: Setup a basic Kubernetes cluster with ease using RKE
• k3s Basic kubernetes with automated installer.
• k3d k3s that runs in docker containers.
• k3OS k3OS is a Linux distribution designed to remove as much OS maintenance as possible in a Kubernetes cluster. It is specifically designed to only have what is needed to run k3s. Additionally the OS is designed to be managed by kubectl once a cluster is bootstrapped. Nodes only need to join a cluster and then all aspects of the OS can be managed from Kubernetes. Both k3OS and k3s upgrades are handled by the k3OS operator.
• k3sup (said 'ketchup') is a light-weight utility to get from zero to KUBECONFIG with k3s on any local or remote VM. All you need is ssh access and the k3sup binary to get kubectl access immediately.
