Load Balancing on Kubernetes with Rancher

When it comes to containerizing user applications and deploying them on Kubernetes, incremental design is beneficial. First you figure out how to package your application into a container. Then, decide on a deployment model – do you want one container or multiple ones – any other scheduling rules, and configuring liveness and readines probes so that if the application goes down, Kubernetes can safely restore it. The next step would be to expose the workload internally and/or externally, so that the workload can be reached by microservices in the same Kubernetes cluster, or - if it’s a user facing app - from the internet.

Using Kubernetes API from Go

Last month I had the great pleasure of attending Kubecon 2017, which took place in Austin, TX. The conference was super informative, and deciding on what session to join was really hard as all of them were great. But what deserves special recognition is how well the organizers respected the attendees’ diversity of Kubernetes experiences. Support is especially important if you are new to the project and need advice (and sometimes encouragement) to get started. Read More…

Load-Balancing in Kubernetes

Update (June 2018): Engineer Alena Prokharchyk revisited this topic and showed useful and easy ways to load balance with Kubernetes in a recent blog post. Kubernetes is the container orchestration system of choice for many enterprise deployments. That’s a tribute to its reliability, flexibility, and broad range of features. In this post, we’re going to take a closer look at how Kubernetes handles a very common and very necessary job: load balancing. Read More…

Comparing Kubernetes and Docker Swarm

For teams building and deploying containerized applications using Docker, selecting the right orchestration engine can be a challenge. The decision affects not only deployment and management, but how applications are architected as well. DevOps teams need to think about details like how data is persisted, how containerized services communicate with one another, load balancing, service discovery, packaging and more. It turns out that the choice of orchestration engine is critical to all these areas. 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.

How to Run GitLab in Rancher - Part 1

*Note: This post is the first in a two-part series on using GitLab and Rancher together for continuous integration and deployment, and part two is now up. We’ve also made the entire walkthrough available for download. * Introduction GitLab is, at its core, a tool for centrally managing Git repositories. As one might expect form a platform that provides this service, GitLab provides a robust authentication and authorization mechanism, groups, issue tracking, wiki, and snippets, along with public, internal, and private repositories.

The Three Pillars of Kubernetes Container Orchestration

In Kubernetes, we often hear terms like resource management, scheduling and load balancing. While Kubernetes offers many capabilities, understanding these concepts is key to appreciating how workloads are placed, managed and made resilient. In this short article, I provide an overview of each facility, explain how they are implemented in Kubernetes, and how they interact with one another to provide efficient management of containerized *workloads. *If you’re new to Kubernetes and seeking to learn the space, please consider reading our case for Kubernetes article.
