Kubernetes provides the freedom to rapidly build and ship applications while dramatically minimizing deployment and service update cycles. However, the velocity of application deployment requires a new approach that involves integrating tools as early as possible in the deployment pipeline and inspecting the code and configuration against Kubernetes security best practices. Kubernetes has many security knobs that address various aspects required to harden the cluster and applications running inside.

As a network of microservices changes and grows, the interactions between them can be difficult to manage and understand. That’s why it’s handy to have a service mesh as a separate infrastructure layer. A service mesh is an approach to solving microservices at scale. It handles routing and terminating traffic, monitoring and tracing, service delivery and routing, load balancing, circuit breaking and mutual authentication.

Kubernetes upgrades are always a tough undertaking when your clusters are running smoothly. Upgrades are necessary as every three months, Kubernetes releases a new version. If you do not upgrade your Kubernetes clusters, within a year, you can fall far behind. Rancher has always focused on solving problems, and they are at it again with a new open source project called System Upgrade Controller. In this tutorial, we will see how to upgrade a K3s Kubernetes cluster using System Upgrade Controller.

Sometimes technology partnerships are greater than the sum of their parts. That’s the case with two Swiss companies who have come together to deliver Kubernetes solutions to their customers. VSHN is Switzerland’s leading 24/7 cloud operations partner and first Kubernetes Certified Service Provider. amazee.io is an open source container hosting provider that offers flexible solutions built for speed, security and scalability.

Rancher Labs’ recent launch of Longhorn was in response to DevOps’ distress call for a cloud-native persistent storage solution for Kubernetes. At the time, industry pundit Chris Mellor posted that the company had entered into direct competition with its partners Portworx and Storage OS. A healthy dose of coopetition may be more like it.

The Rancher Academy launched on May 15, 2020. Here we are, 94 days later, and we’ve issued our 1,000th certificate to a graduate of the Certified Rancher Operator: Level 1 course. Rancher is open source software, so anyone can download it and use it. With that freedom, though, comes a cost: we all learn how to use it according to how we need to use it. Through this lens, the actual potential of Rancher becomes distorted, and the experience of each individual varies widely.

If you’re a gamer, you probably know how immersed you can get in your favorite game. Or if you’re the parent or partner of a gamer, you probably know what it’s like to try to get the attention of someone who is in “gaming mode.” Creating worlds and enriching players’ lives is in Ubisoft’s DNA.

In the pre-Kubernetes, pre-container world, backup and recovery solutions were generally implemented at the virtual machine (VM) level. That works for traditional applications when an application runs on a single VM. But when applications are containerized and managed with an orchestrator like Kubernetes, this system falls apart. That means effective disaster recovery (DR) plans for Kubernetes must be designed for containerized architectures and natively understand the way Kubernetes functions.

Let’s imagine you are running a hosting shop with highly visible production applications. Your team has backups, and you have a disaster recovery (DR) policy. You think you are ready to handle any real-world scenario in addition to checking all your compliance boxes. Your third-party backup tools are creating backups, and your implemented solutions have a brochure indicating restore capability.

PostgreSQL is an open source database known for its reliability and performance. It’s used across many industries and applications, and is especially a favorite of web developers. All major web frameworks support PostgreSQL natively, from node.js and Django to Rails and Spring, so its adaptation is relatively broad across the internet for site backend systems. As with any database, developers need tools to work with them. Pgweb is an open source, web-based client for PostgreSQL.
