  The holy grail for any CMO looking for their next gig is to find the perfect combination of addressable market, market timing, company, and product. That’s why I am so excited to be joining the team at Rancher Labs, the leader in container management software. Let’s look at all the variables. Market Opportunity & Timing The market for containers is conservatively HUGE! What’s a container? A container is a standard unit of software that packages up code and all associated dependencies enabling an application to run quickly and reliably from one computing environment to another.

  The Soft Launch Back in May we did a soft-launch of The RanchCast. We debuted it as a Twitch stream and produced a couple of episodes that you can now find on The RanchCast YouTube channel. After those episodes aired, I went through the feedback from the community and other streamers. Now we’re ready to re-launch. (Re)Introducing The RanchCast The RanchCast is a weekly live stream that allows enginners in the Kubernetes and Rancher communities to interact live with Rancher Labs and with other members of the community.

  Today we are announcing support for Istio with Rancher 2.3 in Preview mode. Why Istio? Istio (or Service Mesh generally) has developed a huge amount of excitement in the Kubernetes eco-system. With its promise of adding fault tolerance, canary rollouts, A/B testing, monitoring and metrics, tracing and observability and authentication and authorization, Istio eliminates the need for developers to instrument or write specific code to enable these capabilities. In effect, developers can just focus on the business logic and leave the rest to Kubernetes and Istio.

  This is the third of a series of three articles focusing on Kubernetes security: the outside attack, the inside attack, and dealing with resource consumption or noisy neighbors. A concern for many administrators setting up a multi-tenant Kubernetes cluster is how to prevent a co-tenant from becoming a “noisy neighbor,” one who monopolizes CPU, memory, storage and other resources. As a result, this noisy neighbor negatively impacts the performance of other users’ resources that share the infrastructure.

  Introduction Kubernetes clusters use multiple certificates to provide both encryption of traffic to the Kubernetes components as well as authentication of these requests. These certificates are auto-generated for clusters launched by Rancher and also clusters launched by the Rancher Kubernetes Engine (RKE) CLI. In Rancher v2.0.x and v2.1.x, the auto-generated certificates for Rancher-launched Kubernetes clusters have a validity period of one year, meaning these certificates will expire one year after the cluster is provisioned.

  Introduction Containers, along with containerization technology like Docker and Kubernetes, have become increasingly common components in many developers’ toolkits. The goal of containerization, at its core, is to offer a better way to create, package, and deploy software across different environments in a predictable and easy-to-manage way. In this guide, we’ll take a look at what containers are, how they are different from other kinds of virtualization technologies, and what advantages they can offer for your development and operations processes.

  Introduction The mechanism for interacting with Kubernetes on a daily basis is typically through a command line tool called kubectl. kubectl is primarily used to communicate with Kubernetes API servers to create, update, delete workloads within Kubernetes. The objective of this tutorial is to provide an overview of some of the common commands that you can utilise, as well as provide a good starting point in managing Kubernetes. We will cover how to install kubectl on your machine, communicate with your Kubernetes environment, and perform some common actions.

  Today I’m excited to announce a new Rancher Labs project called Rio. Rio is a MicroPaaS that can be layered on any standard Kubernetes cluster. Consisting of a few Kubernetes custom resources and a CLI to enhance the user experience, users can easily deploy services to Kubernetes and automatically get continuous delivery, DNS, HTTPS, routing, monitoring, autoscaling, canary deployments, git-triggered builds, and much more. All it takes to get going is an existing Kubernetes cluster and the rio CLI.

  Infrastructure as code is an important methodology for ensuring that your distributed systems are treated as cattle and not pets. Your Kubernetes and Rancher clusters are no different. You should be able to provision your Rancher clusters, your Kubernetes clusters, and all of your apps with automation. Rancher provides a number of tools to spin up Rancher clusters. RKE, or Rancher Kubernetes Engine, allows you to spin up Kubernetes clusters via code.

  Today we are announcing the support for Windows containers with Kubernetes 1.14 in Preview mode. As many users may know, Rancher 2.1.0 supported Windows containers in experimental mode. Now that Microsoft has announced the general availability of containers in Windows Server 2019 with Kubernetes 1.14, we have upgraded Rancher to both support the latest version of Windows containers (and Kubernetes) and after the preview is over, make it generally available.

  Today we launched a new open source project called k3OS. K3OS is a Linux distro built for the sole purpose of running Kubernetes clusters. In fact, it is a Linux distro and the k3s Kubernetes distro in one! As soon as you boot up a k3OS node, you have Kubernetes up and running. When you boot up multiple k3OS nodes, they form a Kubernetes cluster. K3OS is perhaps the easiest way to stand up Kubernetes clusters on any server.

  Introduction Containers have rapidly become a necessary part of the modern data center. Containers can be built on any of a number of operating system foundations — so how do you choose one over another? In the context of a container deployment, development managers need to know which operating system features and functions are critical to the applications being released and whether there are other factors — like manageability and configuration flexibility — that would lead an organization to choose one operating system over another.

  Introduction With over 48,000 stars on GitHub, more than 75,000 commits, and with major contributors like Google and Red Hat, Kubernetes has rapidly taken over the container ecosystem to become the true leader of container orchestration platforms. Kubernetes offers great features like rolling and rollback of deployments, container health checks, automatic container recovery, container auto-scaling based on metrics, service load balancing, service discovery (great for microservice architectures), and more. In this article, we will speak about some basic Kubernetes concepts and its master node architecture, concentrating on the node components.

  Today Google announced Anthos, a new cloud service with the ability to manage Kubernetes clusters across multiple cloud providers, including AWS and Azure. This is super exciting news for Rancher. In Google Anthos, we see great alignment with Rancher’s vision. We believe Kubernetes will become the standardized infrastructure provided by all public and private clouds, and an enterprise Kubernetes platform must deliver multi-cluster, multi-cloud management. Two years ago, we recognized the need for organizations to manage multiple Kubernetes clusters across different public clouds and private data centers.

  This article is a follow up to Native Kubernetes Monitoring, Part One. In this chapter we’ll finish the two remaining demos for the other built-in tools, Probes and Horizontal Pod Autoscaler (HPA). Prerequisites for the Demo If you were following previous chapter then your Rancher instance and Kubernetes cluster should be both up and running. If not, please check the article in order to setup the environment. As a short reminder, we previously mentioned that Kubernetes ships with some built-in tools to monitor the cluster and the many moving parts that form a deployment:

  Developers often believe that demonstrating the need for an IT-based solution should be very easy. They should be able to point to the business problem that needs a solution, briefly explain what technology should be selected, and the funds, staff, and computer resources will be provided by the organization. Unfortunately, this is seldom the actual process that is followed. Developing a Business Case for New Technology Isn’t Always Easy Most organizations require that both a business and a technical case be made before a project can be approved.
