At Deutsche Telekom Pan-Net, we have embraced Istio as the umbrella to cover our services. Unfortunately, there are services which have not yet been migrated to Kubernetes, or cannot be. We can set Istio up as a proxy service for these upstream services. This allows us to benefit from capabilities like authorization/authentication, traceability and observability, even while legacy services stand as they are. At the end of this article there is a hands-on exercise where you can simulate the sc...| Istio Blog

Relative line numbers (relative to the current line) are super popular in the world of Vim, because there it’s super easy to move n lines up or down wiht j and k. In the world of Emacs most of us tend to just go some line using M-g g using a absolute line number or using avy (avy-goto-line). That being said, relative line numbers are easy to enable in Emacs and quite handy if you’re into evil-mode: (setq display-line-numbers-type 'relative) (global-display-line-numbers-mode +1) Relative l...| Emacs Redux

Since implementing HSTS and an HTTPS redirect properly was trickier than I'd imagined, I decided to write my own guide on how to do it. I'll also explain how to configure Nginx to use OSCP Stapling and IPv6 since I worked on getting both of them working at around the same time as I got the proper HTTPS redirect working.

While the pricing for Cloud Files was very agreeable, you really did only...| Cyrozap's Tech Projects

At Intuit, we read the blog post Multi-Mesh Deployments for Isolation and Boundary Protection and immediately related to some of the problems mentioned. We realized that even though we wanted to configure a single multi-cluster mesh, instead of a federation of multiple meshes as described in the blog post, the same non-uniform naming issues also applied in our environment. This blog post explains how we solved these problems using Admiral, an open source project under istio-ecosystem in GitHu...| Istio Blog
Kubernetes operators provide a pattern for encoding human operational knowledge in software and are a popular way to simplify the administration of software infrastructure components. Istio is a natural candidate for an automated operator as it is challenging to administer. Up until now, Helm has been the primary tool to install and upgrade Istio. Istio 1.4 introduces a new method of installation using istioctl. This new installation method builds on the strengths of Helm with the addition of...| Istio Blog
Istio 1.4 introduces an experimental new tool to help you analyze and debug your clusters running Istio. istioctl analyze is a diagnostic tool that detects potential issues with your Istio configuration, as well as gives general insights to improve your configuration. It can run against a live cluster or a set of local configuration files. It can also run against a combination of the two, allowing you to catch problems before you apply changes to a cluster. To get started with it in just minu...| Istio Blog
