Banzai Cloud’s Pipeline platform and Kubernetes distribution tames the complexity inherent in the development, deployment, and scaling of modern containerized applications. The platform seeks to bring the power of cutting-edge cloud and containerization technologies to a wide range of enterprises. “Runners focus on the race they’re running, not the materials their shoes are made of; they trust that their shoes will get them to the finish line,” says Kris Flautner, CEO of Banzai Cloud.

A strong focus on security has always been a key part of the Banzai Cloud Pipeline platform. We incorporated Vault into our architecture early in the design process, and developed a number of supporting components so it be used easily on Kubernetes. We love what Vault enables us to do but, as with many things security-related, strengthening one part of a system exposed a weakness elsewhere. For us, that weakness was K8s secrets, which is the way in which applications usually consume secrets and credentials on Kubernetes.

We will be at KubeCon + CloudNativeCon, Seattle this week experiencing the magic and catching up with people from the broader community. This will be a special event for us as we will be launching the first public beta of our Banzai Cloud Pipeline platform. Let us know if you’d like to chat! Get in touch thru Twitter or LinkedIn. See you there!

Admission webhook series: In-depth introduction to Kubernetes admission webhooks Detecting and blocking vulnerable containers in Kubernetes (deployments) Controlling the scheduling of pods on spot instance clusters Banzai Cloud’s Pipeline platform uses a number of Kubernetes webhooks to provide several advanced features, such as spot instance scheduling, vulnerability scans and some advanced security features (to bypass K8s secrets - more to come next week). The Pipeline webhooks are all open source and available on our GitHub:

As of version 1.6, Kubernetes provides role-based access control (RBAC) so that administrators can set up fine-grained access to a variety of Kubernetes resources. It would take too long to fully explain why it makes sense to use RBAC in this post, but, in a nutshell, RBAC provides a level of control that most enterprises need to meet their security requirements within Kubernetes clusters. Processes and human operators that assume the identity of a Kubernetes Service Account will authenticate with said account and gain its associated access rights.

The Kubernetes scheduler can be constrained to place a pod on particular nodes using a few different options. One of these options is node and pod affinities. In a smaller homogeneous cluster they probably don’t make too much sense, because the scheduler is doing a good job spreading pods on different nodes, - well, that’s its job - but when you have a larger cluster with different types of nodes, maybe even spreading across availability zones, or multiple racks, then affinities may come in handy.

These days it seems that everyone is using some sort a CI/CD solution for their software development projects, either a third-party service, or something written in house. Those of us working on the Banzai Cloud Pipeline platform are no different; our CI/CD solution is capable of creating Kubernetes clusters, running and testing builds, of pulling secrets from Vault, packaging and deploying applications as Helm charts, and lots more. For quite awhile now (since the end of 2017), we’ve been looking for a Kubernetes native solution but could not find many.

Whenever we talk about Kubernetes monitoring and the topic of Prometheus comes up, so does Grafana; the two pretty much go hand in hand. Prometheus query language This article will not serve as an introduction to the powerful Prometheus query language. If you’re not comfortable with Prometheus, now would be a good time to familiarize yourself with the basics of querying and monitoring best practices with Prometheus on Kubernetes. We will only use simple queries with filters and labels in this post.

Banzai Cloud has closed its latest round of seed funding with a total investment of $2.5 million. The round was led by PortfoLion, a Central European venture capital and private equity fund, and included financing from FastVentures and Euroventures of Budapest, the latter being an angel investor that has been with the company since its foundation in 2017. “We’re very excited by this opportunity, by the exceptional team Banzai Cloud has brought together that will make them a force to be reckoned with in the world of enterprise computing.

The Banzai Cloud Pipeline platform allows enterprises to develop, deploy and scale container-based applications. It leverages best-of-breed cloud components, such as Kubernetes, to create a highly productive, yet flexible environment for developers and operation teams alike. One of the main features of the Pipeline platform is that it allows enterprises to run workloads cost effectively by mixing spot instances with regular ones, without sacrificing overall reliability. This requires quite a lot of behind the scenes magic to be built on top of core Kubernetes building blocks.
