A not-so-great way to start into a new week, is to figure out that the certificate of your API server expired on the weekend. Fixing and expired OpenShift certificate should be straight forward, but it wasn’t. Here is what happened, or you can directly scroll down for the solution.
Since OpenShift 4, updates are rather trivial. You wait for the new update to appear, press the button (or use the CLI), wait a bit, and the update is done. True, in production you might want to complicate that process a bit, for good reason.
Running an OpenShift 4 cluster now for a while myself, and developing apps on top of Kubernetes on my day job, I am curious about the next release. Is it GA already? Can I deploy it? Is there an upgrade for my current version? Is that in “candidate”, “fast”, or “stable”? Checking that turned out to be no as easy as it should be.
Quarkus is advertised as a “Kubernetes Native Java stack, …”, so we took it to a test, and checked what benefits we can get, by replacing an existing service from the IoT components of EnMasse, the cloud-native, self-service messaging system.
When you want to containerize your Rust application, you might be using a prepared Rust image. But maybe you are a bit more paranoid when it comes to trusting base layers and you want to create your own Rust base image. Or maybe you are just curios and want to try it yourself.
