At Banzai Cloud we write Kubernetes tools that, no surprise, require other tools to get installed. These tools handle resource lifecycle operations like the installation, upgrade, and removal of various components that need to be integrated together. Kubernetes Operators solve all these and even more for a given application’s domain, but if the focus is simply on installation, upgrade and removal of a set of components - which are in our case operators themselves (operating operators), then we need a tool with different characteristics at hand.

It’s been some time since we open sourced our Kafka Operator, an operator designed from square one to take advantage of the full potential of Kafka on Kubernetes, and have built Supertubes on top to manage Kafka for our customers. One of the most requested enterprise feature has been the implementation of rolling upgrades. Built on the Banzai Cloud’s Kafka operator, Supertubes adds support and orchestrates these upgrades. Accordingly, in today’s blog we’re going to take a deep dive into the technical details of how the operator handles an update and how you can use Supertubes to seamlessly upgrade to the newest 2.

From the beginning, Bank-Vaults has been one of the core building blocks of Pipeline - Banzai Cloud’s container management platform for hybrid clouds. Today we are happy to announce the release of Bank-Vaults 1.0, and the official launch of Bank-Vaults as a product with commercial support. Additionally, we have taken the step of adding Bank-Vaults support for hardware security modules, usually abbreviated as HSMs. Bank-Vaults 1.0 Bank-Vaults was first released two years ago as a Vault operator for Kubernetes, a CLI tool and a Go library.

At Banzai Cloud we support and manage hybrid Kubernetes clusters for our customers across five clouds and on-prem (bare metal, VMware). Therefore, the ability and fluency required to observe these clusters is an absolute must. Very frequently, the Pipeline control plane is tasked with managing multiple Kubernetes clusters, which it does through our own CNCF certified Kubernetes distribution, PKE, or a cloud provider-managed distribution. When that happens, it’s important that we federate metrics, collect them into a single place for querying, analysis and long term storage.

In Kubernetes clusters, the number of Operators and their managed CRDs is constantly increasing. As the complexity of these systems grows, so does the demand for competent user interfaces and flexible APIs. At Banzai Cloud we write lots of operators (e.g. Vault, Istio, Logging, Kafka, HPA, etc) and we believe that whatever system you’re working with, whether it’s a service mesh, a distributed logging system or a centralized message broker operated through CRDs, you will eventually find yourself in need of enhanced observability and more flexible management capabilities.

One of the exciting new features of Istio 1.4 is automatic mutual TLS support, which brings some long awaited convenience to Istio users configuring mTLS for their applications. In this post, we’ll be introducing the concept of Istio’s auto mTLS feature and demonstrating how it works using a demo application. Today, we’ll be using our open-source Banzai Cloud Istio Operator and our multi and hybrid-cloud enabled service mesh platform, Backyards, to install Istio 1.

Our thinking that there was a hunger for an operator that makes easy the provisioning and operating Kafka clusters on Kubernetes which is not based on Kubernetes stateful sets, proved to be correct as shortly after we released the first version our open-source Banzai Cloud Kafka Operator a community started to build around it. We received lots of valuable feedback that helps to shape the future of the Kafka operator and also feature contributions from the community.
