Farewell ingress-nginx, Hello Gateway API

March is all about ingress-nginx and the Kubernetes Gateway API: ingress-nginx is stepping down after years of faithful service. We took a look at what alternatives are available and what the migration entails. If that makes you want to dive right in, our latest tutorial offers a hands-on introduction.

We’re also represented at two events in the coming months: as a Bronze Partner at the TechRiders Summit in Cologne and as a Gold Sponsor at stackconf in Munich. With our ticket codes you can attend both events for free or at a discount.

Enjoy reading!

ingress-nginx is being discontinued

The time has come: following an announcement by the Kubernetes project last November, development of the popular ingress controller ingress-nginx will be discontinued this month.

In our latest article we therefore looked at possible alternatives and the migration effort involved in moving to the Gateway API. The projects we compared were Cilium, Traefik, Contour, Emissary, kgateway and Envoy Gateway.

You can find the details and results of our comparison on our blog.

• Felix gained insights into how Google applies SRE processes in the field of cybersecurity:
  How Google does it: Applying SRE to Cybersecurity
• Daniel read a summary about the removal of the batch processor in OpenTelemetry:
  Why the OpenTelemetry batch processor is going away eventually
• Sebastian learned about the deliberately boring technology stack of Incident.io:
  Keeping it boring: the incident.io technology stack
• Achim picked up fresh ideas on code reviews in the age of AI:
  How to Do Code Reviews in the Agentic Era
• Kleon now knows why etcd can become a problem in very large Kubernetes environments:

Bash Special Parameters - $?, $$ and $!

Your Bash environment doesn’t just populate a few environment variables like HOME or PATH for you. There are also a handful of special variables that are always available.

Three of them are particularly useful: $? holds the exit code of the last command, $$ the PID of the current shell - handy for collision-free temp files, for example. $! gives you the PID of the most recently backgrounded process.
