From Cattle to K8s - Service Discovery in Rancher 2.0

From Cattle to K8s - Service Discovery in Rancher 2.0

Service discovery is one of the core functionalities of any container-based environment. Once you have packaged your application and launched it using containers, the next step is making it discoverable to other application containers in your environment or the external world. In this article we will go over the service discovery support provided by Rancher 2.0 and see how the Rancher 1.6 feature set maps to the latest version. Read More…

Containers vs. Serverless Computing

Serverless computing is a hot topic right now—perhaps even hotter than Docker containers. Is that because serverless computing is a replacement for containers? Or is it just another popular technology that can be used alongside containers? In this post, I take a look at what you need to know about serverless computing, and how it should figure into your IT strategy. Serverless Is Not Server-less But first, let’s clear up one point: As you may already know, serverless computing does not mean that there are no servers involved. Read More…

Microservices Made Easier Using Istio

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.

Running Serverless Applications on Rancher

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?

Lessons Learned Building a Deployment Pipeline with Docker, Docker Compose and Rancher (Part 4)

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.

Using Rancher Compose Templates to Build a Secure Consul Cluster

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. Read More…
