Container Conundrum: DevOpsDays Chicago 2022 Open Space Notes

I found a topic that I’m going to suggest for an Open Space at every DevOpsDays I go to from this point forward: “Container Conundrum: Pain points around containers” These notes are presented here without opinion. Distilling these notes into a concise narrative will be the topic for an introduction to an upcoming DevOps’ish newsletter. Please subscribe today!

Intro to eBPF

This introduction to eBPF is adapted from the beginning of DevOps’ish 278 I occasionally ask for writing prompts from folks on Twitter for DevOps’ish. Sometimes asking on social media works well.

Abstract GitOps is a prescriptive way of implementing DevOps. You will not succeed in using GitOps if you haven’t embraced some DevOps philosophies along the way. In this talk, we’ll look at the GitOps Principles and see how they align to existing or new DevOps/SRE functions. GitOps, being a wonderful implementation of DevOps functionality in cloud native environments and beyond, will enable organizations to prescriptively shift left, improve release velocity, and hopefully reap all the other benefits that higher performers in the State of DevOps reports see....

2019 Learnings, 2020 Expectations

A former co-worker and now friend has a tagline, “Every day is a school day.” I remind myself of this fact almost every time I learn something new. 2019 was the hardest year of my life. I’d like to share some things I picked up on this most recent journey around the sun we call 2019. I’ll make some predictions about 2020 in the process too. Kubernetes Last year, I said I thought Kubernetes would get easier....
