From Cattle to K8s - How to Publicly Expose Your Services in Rancher 2.0

Real world applications deployed using containers usually need to allow outside traffic to be routed to the application containers. Standard ways for providing external access include exposing public ports on the nodes where the application is deployed or placing a load balancer in front of the application containers. Cattle users on Rancher 1.6 are familiar with port mapping to expose services. In this article, we will explore various options for exposing your Kubernetes workload publicly in Rancher 2.

RED Method for Prometheus - 3 Key Metrics for Monitoring

On July 25th, Luke Marsden from Weaveworks and Bill Maxwell from Rancher Labs led a webinar on ‘A Practical Toolbox to Supercharge Your Kubernetes Cluster’. In the talk they described how you can use Rancher and Weave Cloud to set up, manage and monitor an app in Kubernetes. In this blog, we’ll discuss how and why Weave developed the best-practice RED method for monitoring apps with Prometheus. What is Prometheus Monitoring? Read More…

What App Developers Should Know About Kubernetes Networking

In the world of containers, Kubernetes has become the community standard for container orchestration and management. But there are some basic elements surrounding networking that need to be considered as applications are built to ensure that full multi-cloud capabilities can be leveraged. The Basics of Kubernetes Networking: Pods The basic unit of management inside Kubernetes is not a container—It is called a pod. A pod is simply one or more containers that are deployed as a unit.

A Day in the Life of a Packet Inside Rancher

[Rancher is a complete container management solution, and to be a complete platform, we’ve placed careful consideration into how we handle networking between containers on our platform. So today, we’re posting a quick example to illustrate how networking in Rancher works. While Rancher can be deployed on a single node, or scaled to thousands of nodes, in this walkthrough, we’ll use just a handful of hosts and containers.] Setting up and Launching a Containerized Application [Our first task is to set up our infrastructure, and for this exercise, we’ll use AWS.

Magento with Docker Updated, Using Load Balancers for Scalability and Availability

A little over a month ago I wrote about setting up a Magento cluster on Docker using Rancher. At the I identified some short comings of Rancher such as its lack of support fot load-balancing. Rancher released support for load balancing and docker machine with 0.16, and I would like to revisit our Magento deployment to cover the use of load balancers for scalability as well as availability. Furthermore, I would also like to cover how the docker machine integration makes it easier to launch Rancher compute nodes directly from the Rancher UI. Read More…

Building a Continuous Integration Environment using Docker, Jenkins and OpenVPN

Since I started playing with Docker I have been thinking that its network implementation is something that will need to be improved before I could really use it in production. It is based on container links and service discovery but it only works for host-local containers. This creates issues for a few use cases, for example when you are setting up services that need advanced network features like broadcasting/multicasting for clustering. Read More…

Docker Load Balancing Now Available in Rancher 0.16

Hello, my name is Alena Prokharchyk and I am a part of the software development team at Rancher Labs. In this article I’m going to give an overview of a new feature I’ve been working on, which was released this week with Rancher 0.16 - a Docker Load Balancing service. One of the most frequently requested Rancher features, load balancers are used to distribute traffic between docker containers. Now Rancher users can configure, update and scale up an integrated load balancing service to meet their application needs, using either Rancher’s UI or API. Read More…
