March 2020 Online Meetup: Automating K3s Cluster Upgrades

While developing K3s to run at the edge we had to change our assumptions about how to manage these clusters at scale. A key assumption in a data center is that you have stable network connectivity, but this may not be true at the edge. You may have unreliable cellular service or limited time during the day in which you can connect. In these environments, operations such as upgrading Kubernetes or patching an operating system require a different paradigm.

Kubernetes Master Class: How to implement Network Policy to secure your cluster

By default, pods are non-isolated; they accept traffic from any source. The Kubernetes solution to this security concern is Network Policy that lets developers control network access to their services. Rancher comes configured with Network Policy using Project Calico which can be used to secure your clusters. This class will describe a few use cases for network policy and a live demo implementing each use case.

Kubernetes Master Class: Find Security Vulnerabilities in your Kubernetes Cluster

Security is one of the most talked-about topics for Kubernetes users. Google “Kubernetes security” and you'll find a huge number of articles, blogs and more. The reason is simple: you need to align your container and Kubernetes security with your organization’s existing security profile.

The GitOps Kubernetes Connection

In the first article in this series, we talked about making Kubernetes essential to your DevOps pipeline. We reviewed CI/CD and DevOps and why their relationship with Kubernetes is so powerful. In this article, I’m going to dive into another term in the application development and management mix: GitOps. We’ll cover what GitOps is, how it affects an organization and how it aligns with Kubernetes.

Kubernetes Master Class: True Hybrid Cloud for Kubernetes with Rancher and HPE

One of the benefits of Kubernetes is the ability to run your applications everywhere in a simple manner. The conversation changes drastically when persistent storage is deployed with the application and the deployment becomes sticky as data has gravity.

Citrix and Rancher Integration: Cloud-Native Stack on Kubernetes

Kubernetes and containers are changing how applications are built, deployed and managed. Rancher makes application deployment simple and easily portable regardless of location or infrastructure. At Citrix, we operate on the same core principle. We provide application delivery and load balancing solutions for a high-quality user experience, to any device, across any network, for your web, traditional and cloud-native applications regardless of where they are hosted.

Migrate Your Windows 2003 Applications to Kubernetes

There’s no one-size-fits-all migration path for moving legacy applications to the cloud. These applications typically reside on either physical servers, virtual machines or on premises. While the goal is generally to rearchitect or redesign an application to leverage cloud-native services, it’s not always the answer.

Kubernetes Master Class: How to Run Databases in Production on Kubernetes

Databases are business-critical entities and data loss leads to major operational risk scenarios in any organization. A single operational or architectural failure can lead to significant loss of time and resources. This class will provide a real-world view into the challenges of maintaining state and running databases in production and show solutions managed by Rancher.
