#KUBE100: The Story So Far

On an unassuming afternoon on Wednesday the 18th September 2019, we launched a world’s first! A k3s-powered, managed Kubernetes service. We were in for a ride... Since we had been taking applications for a few weeks already, when it came to beta launch day there were no shortage of applicants. It was very encouraging to see there was plenty of buzz online already.

DevOps Patterns and Antipatterns for Continuous Software Updates at Velocity Berlin 2019

So, you want to update the software for your user, be it the nodes in your K8s cluster, a browser on user’s desktop, an app in user’s smartphone or even a user’s car. What can possibly go wrong? In this talk, we’ll analyze real-world software update fails and how multiple DevOps patterns, that fit a variety of scenarios, could have saved the developers. Manually making sure that everything works before sending an update and expecting the user to do acceptance tests before they update is most definitely not on the list of such patterns.

Rancher Labs Industry Survey Shows Rapid Adoption of Containers and Kubernetes, But Challenges Remain

To get an accurate picture of the current state of Kubernetes deployments, Rancher Labs recently conducted an industry survey that included 1,106 respondents from large and small enterprises across a broad range of more than 25 industries, including technology, financial services, telecom, education, government and healthcare. The respondents were almost evenly split among EMEA and North America and included both Rancher and non-Rancher users.

How to Create an Azure Monitor Alert

Azure Monitor gathers performance metrics from your various Azure resources and allows you to explore those metrics through visualizations. It also allows you to manually create alerts that will notify you when a metric crosses a predefined threshold. In this blog post, we’ll cover how to create an alert in Azure Monitor.

Understanding common library implementation

As Falco grows in popularity, many new users get exposed to it on a daily basis. As should be expected, most of these users are not aware of what the architecture underneath Falco is. What components play a role in powering it? How do these components relate to each other? I thought it would be fun to write a blog post that answers these questions. And I thought it would be fun to write it with an historical perspective.

Serverless Vs. Containers - the big showdown

If you have anything to do with the world of cloud computing or even programming for that matter, then I’m sure you’ve heard of different terms being tossed around such as “serverless computing” or “containers,” and even “monolithic architectures.” A lot of people who understand such computing methods can have a bad habit of using these terms without leaving any explanation as to what they are.

Monitor your Fargate container logs with FireLens and Datadog

To centralize logging from your entire stack—from traditional infrastructure to serverless components—Datadog is announcing native support for the launch of FireLens for Amazon ECS. FireLens streamlines logging by enabling you to configure a log collection and forwarding tool such as Fluent Bit directly in your Fargate tasks. We’ve partnered with AWS to provide built-in Fluent Bit support for Datadog so that you can now seamlessly route container logs from AWS Fargate.

Upgrading Kubernetes Without Upgrading Rancher

Prior to version 2.3, new versions of Kubernetes came out with point releases of Rancher and required an upgrade to Rancher before they were made available for use. Rancher 2.3 changes that pattern and now makes it possible to update the metadata store for available Kubernetes versions, disconnecting the Rancher server upgrade process from the Kubernetes cluster upgrade process.
