Illumina Innovates with Rancher and Kubernetes
Rancher looks at what you need to know about serverless computing, how it compares to containers, and how it can figure into your IT strategy. Learn more.
This article is a continuation in a series on migrating from Rancher 1.6 to Rancher 2.0. Learn more about how internal service discovery works in Rancher 2.0
In this post, we’ll discuss how we implemented consul for service discovery with Rancher. John Patterson (@cantrobot) and Chris Lunsford run This End Out, an operations and infrastructure services company. You can find them online at* https://www.thisendout.com *and follow them on twitter @thisendout. ** If you haven’t already, please read the previous posts in this series: Part 1: Getting started with CI/CD and Docker Part 2: Moving to Compose blueprints Part 3: Adding Rancher for Orchestration In this final post of the series on building a deployment pipeline, we will explore some of the challenges we faced when transitioning to Rancher for cluster scheduling.
Update: This tutorial on Istio was updated for Rancher 2.0 here.
One of the recent open source initiatives that has caught our interest at Rancher Labs is Istio, the micro-services development framework. It’s a great technology, combining some of the latest ideas in distributed services architecture in an easy-to-use abstraction. Istio does several things for you. Sometimes referred to as a \“service mesh\“, it has facilities for API authentication/authorization, service routing, service discovery, request monitoring, request rate-limiting, and more.
One of the more novel concepts in systems design lately has been the notion of serverless architectures. It is no doubt a bit of hyperbole as there are certainly servers involved, but it does mean we get to think about servers differently.
The potential upside of serverless Imagine a simple web based application that handles requests from HTTP clients. Instead of having some number of program runtimes waiting for a request to arrive, then invoking a function to handle them, what if we could start the runtime on-demand for each function as a needed and throw it away afterwards?
Recently, Rancher released a community catalog that will contain entries of Compose templates generated by the community. By default, the catalog in Rancher UI is populated from the Rancher catalog repository under the name “library catalog”. Now, you can also see the community catalog as well. This post will introduce how to build a secure Consul cluster as a Rancher Compose template that will be an addition to the newly released Rancher community catalog.
