In this post, I’ll show you how to use the new, web-based interface in Cloudflare to quickly configure a tunnel to your local resources for free. I’ll share some resources to improve the security and resiliency of the tunnel if you need it on a more permanent basis as well.
Kubernetes, or k8s, is an important container orchestration platform. In this blog, I’ll describe creating a workable Kubernetes cluster implemented on a stack of four Raspberry Pi boards. In the end, I’ll have provided an outline of how I created it and I’ll show how to replicate a stateless app across Kubernetes pods running on the nodes — the Pi boards.
The steps described in this blog post allow for the adding of a Logic App on Azure to append rows to an Excel file. It took a lot of trial, and mostly error, to figure out how to describe what I wanted in the way that the Logic App would understand. Hopefully, the steps that I outlined in this blog post will save others the time it took me to come up with them.
Back in 2015 and 2016, I wrote two blogs that went step by step to develop a microservice/Netty architecture with fully working code called Whirlpool.
A lot has changed in the years since, so recently I decided to come back to the project, update it with the latest versions of Kafka and Netty, and add a React UI to it (rather than the vanilla JavaScript version it used before). In addition, I also added Windows Subsystem for Linux (WSL) scripts in addition to the Mac and Linux scripts that were there before and made all of the scripts more robust.
This blog will be about the work that went into all of those updates, plus a look at the new React UI. This provides an excellent view into what it takes to update an outdated microservices application implemented with Kafka (version .9 –>3.0) and Netty (4.1.3->5.0.0-alpha2), bringing all versions up to date and adding a React UI. By the end you’ll be familiar with the latest versions of these frameworks, know some “gotchas” to avoid, as well as understand how to integrate WebSockets into React.
This presentation explores a Terraform-based approach to Infrastructure as code. Infrastructure is becoming more and more important for us as developers to understand and develop; it’s no longer only in the hands of the operations team. Terraform is a great tool for infrastructure management.
