See Github Releases page to find the latest available release. For example, to download version v0.4.0 on Linux, execute the following command: VERSION=v0.4.0 It will download the flexkube binary into your current directory. It is recommende to move this binary into one of directories mentioned in your $PATH environment variable, e. https://flexkube.github.io/documentation/getting-started/installing/go/ Mon, 01 Jan 0001 00:00:00 +0000 https://flexkube.github.io/documentation/getting-started/installing/go/ Go module Recommended way of using Flexkube in your Go project is via libflexkube library. libflexkube uses Go modules to manage it’s dependencies, so it is also recommended for your project to use it. To add libflexkube module to your project, simply run the following command: go get github.com/flexkube/libflexkube It will import latest release of libflexkube into your project. With module added, go to Go examples to see how to use it in your code or see reference documentation to see all available packages. https://flexkube.github.io/documentation/getting-started/installing/terraform/ Mon, 01 Jan 0001 00:00:00 +0000 https://flexkube.github.io/documentation/getting-started/installing/terraform/ Terraform provider Using Terraform 0.13 and Terraform Registry The easiest way to get Flexkube Terraform provider is to pull it from the Terraform Registry. You can do that by adding the following snippet to required_providers block in terraform block in your module configuration: flexkube = { source = "flexkube/flexkube" version = "0.4.0" } So example versions.tf file would look like following: terraform { required_providers { flexkube = { source = "flexkube/flexkube" version = "0. https://flexkube.github.io/documentation/getting-started/requirements/creating-virtual-machines-for-testing/ Mon, 01 Jan 0001 00:00:00 +0000 https://flexkube.github.io/documentation/getting-started/requirements/creating-virtual-machines-for-testing/ Creating virtual machines for testing If you don’t have a spare machine available for testing, you can create it locally, using VirtualBox and Vagrant. Make sure you have both tools installed by following respective guides: Installing VirtualBox Installing Vagrant Single node If you need just one machine, create file named Vagrantfile with the following content: Vagrant.configure("2") do |config| config.vm.box = "flatcar-stable" config.vm.box_url = "https://stable.release.flatcar-linux.net/amd64-usr/current/flatcar_production_vagrant.box" config.ssh.username = 'core' config.vm.provider :virtualbox do |v| v. https://flexkube.github.io/documentation/guides/etcd/creating-multi-member-cluster-over-ssh-using-terraform/ Mon, 01 Jan 0001 00:00:00 +0000 https://flexkube.github.io/documentation/guides/etcd/creating-multi-member-cluster-over-ssh-using-terraform/ Creating multi-member cluster over SSH using Terraform This guide describes how to create multi member etcd cluster using Terraform and Flexkube provider. The process is very simple and requires just a few steps. If you have at least 3 members, your cluster will be able to tolerate loss on one member, so it will be highly available.

responsible for generating all X.509 certificates and RSA key pairs which are required by Kubernetes cluster. Kubernetes requires several certificates to be generated, with specific CNs, different CAs etc, which is difficult to manage, so Flexkube provides configurable and convenient interface to manage them. All certificates are generated by following Kubernetes PKI certificates and requirements best practices. Current implementation of PKI is experimental and only supports generating the certificates.
