VSHN.timer #108: Podman Forever

13. Sep 2021

Welcome to another VSHN.timer! Every Monday, 5 links related to Kubernetes, OpenShift, CI / CD, and DevOps; all stuff coming out of our own chat system, making us think, laugh, or simply work better.

No, this week we’re not going to talk about yet another superhero movie, but rather about the new standard tool for building and running containers.

1. Early this year we mentioned that the competition between Docker and Podman was heating up. Well, lately the Podman team has accelerated its velocity to unprecedented levels, and released version 3.3, with a ton of new features that set it far ahead in the race.

2. The recent announcement by Docker of a new subscription policy for Docker Desktop has triggered a massive increase of interest in Podman–and a certain amount of controversy and backlash, too. In a much more positive note, Markus Noble has wrote a very useful guide to help cloud native developers migrate from Docker to Podman.

3. Docker (the company) has lost a lot of buzz and inertia since 2013. What happened? Being in the eye of the Cloud Native hurricane was certainly not easy, and many decisions by their management hurt the company in unforeseen ways. This article by Scott Carey on InfoWorld tells the gripping story of the rise and fall of one of the hottest startups of the 2010s.

4. You most probably have heard about EKS Anywhere already: the very same Kubernetes distribution that Amazon uses in EKS, but ready to install in your own infrastructure. The thing is, nobody wants to manage yet another Kubernetes cluster (hint: call us! *wink wink*), so you’d better read what Kohei Ota has to say about EKS Anywhere first. And then watch out, because Kubernetes can be expensive.

5. This is a really cool idea: ttl.sh is an anonymous and ephemeral container image registry by Civo: just tag your image with the required time-to-live information, push, and it will be deleted automatically when the time’s up. And even better, you can use cosign with it, as explained here.
