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! I think the best way to look at these notes is to assume that each bullet point is a pain point....

Windows 11: How to Install WSL2 and Linux Distros

I’m not going to lie. Windows Subsystem for Linux (WSL) is a helpful technology. It’s supposed to have made getting a Linux environment on Windows easier. However, having just tried getting it up and running on the lone Windows box I own, I can confirm it’s a pain to install unless you’re a Windows system administrator or know what you’re doing. The hype for WSL2 appears to have overlooked the user experience....

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. Other times it’s giving someone a good URL and still scratching my head about what to write. But for DevOps’ish 278, the people have spoken. They want to learn more about eBPF. What is eBPF? eBPF (which is no longer an acronym for anything) is a revolutionary technology with origins in the Linux kernel that can run sandboxed programs in a privileged context such as the operating system kernel....

code-server, Caddy, Tailscale, and Hugo = My ultimate dev environment

I think I’ve discovered my development environment equivalent to nirvana. code-server fronted by Caddy on a box with Tailscale installed. I maintain a lot of Hugo websites. Hugo has been my go-to content management system (CMS) since discovering it in 2017 (I got my first Hugo site at GopherCon 2017). I’ve lost count of the number of domains I own (a common nerd problem). But, I know I have a handful of websites I update regularly....

Please read my Disclaimer before breaking out the tar and feathers. To say that Docker had a very rough 2017 is an understatement. Aside from Uber, I can’t think of a more utilized, hyped, and well funded Silicon Valley startup (still in operation) fumbling as bad as Docker did in 2017....

Install VirtualBox Guest Additions via Command Line

I routinely spin up CentOS virtual machines in VirtualBox. Sometimes they are temporary and others might be around for months. These seemingly throw away VMs utilize the CentOS minimal install ISO for speed of setup (I really should just build a standard starting point VM and clone it as needed but I digress). I understand that installing the VirtualBox guest additions is a nicety for some so you probably rarely do it....

Linux Directory Structure

For more information about the Linux directory structure see the Filesystem Hierarchy Standard (FHS) which is part of the Linux Standard Base (LSB) which is a workgroup of the Free Standards Group. / The root directory (not to be concerned with the root account) is similar to a drive letter in Windows (C:, D:, etc.) except that in the Linux directory structure there is only one root directory and everything falls under it (including other filesystems and partitions)....
