Project configuration inside and outside of Kubernetes

Recently, I wrote a response about the life of a project in Docker and debugging code outside of it, where I briefly mentioned that you can create your own configuration system so that the service works well in Kubernetes, retrieves secrets, and runs conveniently locally, even completely outside of Docker. It's nothing complicated, but the described 'recipe' may be useful to someone 🙂 The code on […]

Building an Inexpensive Home NAS System on Linux

Like many other MacBook Pro users, I faced the issue of insufficient internal storage. To be more specific, my daily-used rMBP was equipped with a 256GB SSD, which, of course, was not enough for the long term. And when I started recording videos during my flights, the situation only worsened. The amount of footage recorded after such flights […]

Setting Up a Django Stack on MS Windows

This article will provide a detailed guide on installing and configuring Apache, Python, and PostgreSQL to run a Django project on MS Windows OS. Django already includes a simplified development server for local code testing, but for production tasks, a more secure and powerful web server is required. We will configure mod_wsgi to interact with […]

Using IPv6 in Advanced Direct Connect

Observing the development of the file exchange network is interesting, but participating in it is even more exciting. Nowadays, by setting up and launching a modern NMDC hub, a newly minted administrator gains access to nearly all the developments and accumulated experience in this field from predecessors. They have a system ready for expansion and customization, including through numerous scripts. With ADC hubs […]

12 tools that make Kubernetes easier.

Kubernetes has become the standard method, and many will attest to this as they deploy containerized applications at various scales. But while Kubernetes helps us manage messy and complex container deliveries, what helps us manage Kubernetes itself? It can also be complex, convoluted, and hard to manage. As Kubernetes grows and evolves, many of its nuances will certainly be addressed within […]

Turing Pi — a cluster board for self-hosted applications and services.

Turing Pi is a solution for self-hosted applications built on the rack-mount principle found in data centers, only on a compact motherboard. The solution is geared toward building local infrastructure for local application and service development and hosting. Essentially, it's like AWS EC2 but for the edge. We are a small team of developers who decided to create a solution for building bare-metal clusters in the edge […]
