DevOps'ish

DevOps, Cloud Native, Open Source, and the ‘ish in between.

117: Docker Layoffs, Purl, Linus Knocks Arm, Killing k8s, Ansible, OperatorHub, Gremlin, PostgreSQL Operator, and More

Docker confirmed they laid off folks. A source stated Docker closed their APAC office, laid off some developers, and punted some sales folks in Europe too. The source thought some managers on the development teams would be leaving soon as well. I have absolutely no real way of confirming that. But, all is well at Docker if you ask them. Things are so well in fact, that when a reporter reached out to Docker to ask about layoffs (based on a tweet from a random technologist), their PR team called the reporter to give them an “exclusive” interview with the Docker CEO to bury the layoffs. That’s totally normal behavior for a company that’s doing just peachy I guess. ¯\_(ツ)_/¯ Regardless, if you’re impacted and want help, let me know.

In personal news, it appears my eight-year long appeal with the Veteran’s Administration has come to an end. As I mentioned in the Twitter thread, there’s a lot to unpack here. It’s been an overwhelming week and finding out life-changing news at the end of it is wild but on brand for 2019 so far.

We Need Chrome No More — “Ten years ago, we needed Google Chrome to break the Web free from corporate hegemony, and we managed to do so for a brief period. Today, its dominance is stifling the very platform it once saved from the clutches of Microsoft. And no one, beside Google, needs that.”

Tools

A quickstart guide to Ansible — A month ago, someone on my team (pretty sure my awesome boss) mentioned Ansible’s birthday was coming up (February 23rd-ish). Jason Hibbets and I huddled up with the Opensource.com team and built a nice looking book for y’all. Happy 7th birthday, Ansible!
