TK8 Cattle EKS Provisioner with Terraform Rancher Provider

31. Dezember 2019 Digitalisierung

In a previous post we introduced how to use a Rancher Server with Terraform Rancher Provider to deploy Rancher’s Kubernetes Engine (RKE) with the TK8 Cattle AWS provisioner on auto-provisioned EC2 machines. In this post I’ll introduce the TK8 Cattle EKS provisioner by the awesome Shantanu Deshpande to deploy an EKS Cluster with the tk8ctl tool talking to a Rancher Server using a valid SSL certificate running on our local machine. Rancher launched EKS vs. Rancher launched RKE Cluster With Rancher Serverweiterlesen

Deploy K8s using K8s with Cluster API and CAPA on AWS

26. Dezember 2019 Digitalisierung

This post provides some insights about Cluster API (CAPI), a Kubernetes Lifecycle SIG project and how to use it together with Cluster API Provider for AWS (CAPA) on any Kubernetes Cluster to create a single or a fleet of Vanilla Kubernetes cluster(s) on AWS or other supported providers. Cluster API is very new and was inspired by Kubicorn and Kops projects and I guess some concepts was looked up by Rancher’s way of bootstrapping clusters. At this time of writingweiterlesen

A small talk with the Kommander about Cattle AWS vs. Cattle EKS The Kommander I met this lovely captain recently on Kos Island and had a small talk with her/him regarding our Kubernetes projects. I spoke to her/him about a dilemma which we’re facing these days. This write up is a very short abstract of our conversation, which I’d like to share with you. In the meanwhile our lovely captain has joined us as “The Kommander” and has the code name TK8. We’reweiterlesen

Simplicity matters: Kubernetes 1.16

22. September 2019 Digitalisierung

Simplicity matters: Kubernetes 1.18.2 on your local machine with kubeadm and Multipass, Rancher k3s, RKE & more .. I was playing with Multipass VMs, Rancher k3s, RKE and Rancher Server on my laptop (MacOS) in the last 2 weeks and did some small implementations to fully automate the deployment of k3s, RKE and Rancher Server on my local machine, mainly for faster and cheeper testing of upgrades of RKE and Rancher and to provide a local real multi-node environment for trainings.weiterlesen

Kafka Topic backup to S3 and restore to another Kafka cluster using Strimzi and OpenEBS

19. August 2019 Digitalisierung

Photo by Martin Adams on Unsplash TL;DR Deploying Kafka via Strimzi operator (Helm chart), storage backed by OpenEBS. Taking backup of Kafka Topics to S3 with Kafka Connect Spredfast S3 Connector, restore Kafka Topics to a different Kafka cluster. Introduction While an introduction would usually begin talking about what is Apache Kafka, OpenEBS and other software components that we have here and “should you be running Kafka on Kubernetes or not?”, I’m going to skip that part as I believe if youweiterlesen

The Enterprise Grade Rancher Deployment Guide, the hard way

18. August 2019 Digitalisierung

The Enterprise Grade Rancher Deployment Guide Photo by Priscilla Du Preez on Unsplash Introduction There are many ways to have an Enterprise Grade Kubernetes cluster running with Rancher Server and Rancher Kubernetes Engine (RKE). This guide provides a very, perhaps too much detailed, step by step guide which we have been using by various projects in “production” on Bare-Metal servers and in the cloud. In this guide we describe how to use the rke tool to setup a RKE cluster and useweiterlesen
