DevOps Industry Updates #13

Welcome back to DevOps Industry updates! WFH remains a hot topic in big tech and for the first time in 5 years, HashiCorp introduces not one but two new open-source projects: Boundary and Waypoint. Amazon also released their new time-series database called Timestream and most importantly, we finally now have a way to kill Kubernetes pods with a Doom-like interface. It’s all right here in issue #13:

  • Dropbox will let all employees WFH permanently by Allana Akhtar: the company turns its offices into WeWork-like ‘collaborative spaces’ to aid in team building and collaboration. “While we know we may not get it 100% right immediately, we wanted to take this opportunity to fundamentally redesign how we work, and be more intentional and prescriptive with the guidance we’re giving to our employees,” a Dropbox spokesperson said.

  • Why the Serverless Revolution Has Stalled by Bernard Brode: this article takes a look at why, despite serverless models finding great utility in specific, well-defined circumstances, it seems that the lack of agility and flexibility of these systems is still a barrier to their more widespread adoption.

  • A Hitchhiker’s Guide to Containerizing (Spring Boot) Java Apps by Nicolas Fränkel: containerizing an application based on a “scripting” language is straightforward. Add the sources, download the dependencies, and you’re good to go. With compiled languages in general and Java in particular, things are a bit different. In this post, I’d like to list some alternatives to achieve that.

  • It’s Time to Forget About Docker by Martin Heinz: in the ancient times of containers, Docker was the only player in the container game. That’s not the case anymore though and Docker is not the only, but rather just another container engine on the landscape. Docker allows us to build, run, pull, push or inspect container images, but for each of these tasks there are other alternative tools, which might just do a better job at it than Docker. So, let’s explore the landscape and (just maybe) uninstall and forget about Docker altogether…

  • CVE-2020-15157 ContainerDrip by Brad Geesaman: if an attacker publishes a public image with a crafted manifest that directs one of the image layers to be fetched from a web server they control and they trick a user or system into pulling the image, they can obtain the credentials used by ctr/containerd to access that registry. In some cases, this may be the user’s username and password for the registry.
