Zeebe Kubernetes Operator (experimental)

I am happy to announce the experimental release of the Zeebe Kubernetes Operator. If you are looking at Zeebe and Kubernetes together the Zeebe Kubernetes Operator should improve your journey to provision and manage Zeebe Clusters. Here is a more detailed blog post about how to use it and how it works. This are very early stages of the project, that means it is a great time to get involved, provide feedback and if you are interested get in touch to work on some issues. Get in touch Is there a Zeebe topic that you’d like to see explored more deeply in a blog post? Let our dev advocates know on Twitter! Josh Salaboy Questions? Feedback? If you have questions…

The Job Executor: What Is Going on in My Process Engine?

Sometimes we start a process, and after some initial processing, it does not continue for no apparent reason. Usually, this happens at asynchronous continuations or BPMN timer events, so points in the process where the job executor, the process engine’s component for deferred work, takes over. While the job executor is a well-tested and battle-proven piece of software, it is not a closed system. It integrates with a relational database, an application server and the processes and applications it runs. Problems with job execution typically arise in this interaction of components. In this article, we look at common reasons why job execution can be delayed or stuck, how to diagnose, and how to resolve them.

Transactional Email Microservice with Zeebe and NestJS

NestJS is a JavaScript Microservices framework for Node.js inspired by Angular. For some time now, front-end developers have been able to get the benefits of configuration by convention, dependency injection, and composition using decorators to build code bases whose structure can scale. Now it’s time for backend developers to get the same benefits. NestJS is a framework that clearly meets a need felt in the community – it was the fastest growing Node.js framework in 2018 (measured by GitHub stars). NestJS leverages TypeScript, decorators, and the MVC architecture to enable developers to build applications that communicate over REST, WebSockets, gRPC, and GraphQL. With a new library from Dan Shapir – nestjs-zeebe – you can now integrate Zeebe into a NestJS…

Zeebe and IoT: Node-RED

Patrick (Paddy) Dehn and Cornelius Suermann join me on the Camunda Nation podcast this week to talk about Zeebe, IoT, and workflow automation. Paddy is a developer working on Operate, the web-based UI for Zeebe workflow inspection and management, and Cornelius is the engineering director for Camunda Cloud. They are also both massive IoT nerds. Paddy is the author of the open-source Zeebe nodes for Node-RED. We talk about their personal home automation projects, the Zeebe nodes for Node-RED, and some of the possibilities for massively scaled workflow automation in the cloud with Camunda Cloud, Zeebe, and IoT. Check them out on GitHub: Cornelius on GitHub Paddy on GitHub
