A show about getting your best ideas into the world and seeing what happens. We talk about code, ops, infrastructure, and the people that make it happen. Gerhard Lazu and friends explore all things DevOps, infra, and running apps in production. Whether you’re cloud native, Kubernetes curious, a pro SRE, or just operating a VPS… you’ll love coming along for the ride. Ship It honors the makers, the shippers, and the visionaries that see it through. Some people search for ShipIt or ShipItFM and can’t find the show, so now the strings ShipIt and ShipItFM are in our description too.

Kaizen! Four PRs, one big feature
In today’s Kaizen episode, we talk about shipping Adam’s Christmas present: chapter support for all Changelog episodes that we now publish. This feature was hard because there are many subtle differences in how the ID3 spec is implemented. Of course, once the PR shipped, there were other issues to solve, including an upgrade the world kind of scenario. Since Lars Wikman did all the heavy ID3 lifting, he is here with us too.
The cloud native ecosystem
Maybe it’s the Californian sun. Or perhaps it’s the time spent at Disney Studios, the home of the best stories. One thing is for sure: Taylor Dolezal is one of the happiest cloud native people that Gerhard knows. As a former Lead SRE for Disney Studios, Taylor has significant hands-on experience running cloud native technologies in a large company. After a few years as a HashiCorp Developer Advocate, Taylor is now Head of End User Ecosystem at CNCF. In his current role, he is helping enable cloud native success for end-users like Boeing, Mercedes Benz & many others.
Behind the scenes at Microsoft Azure
In today’s episode, we talk to Ganeshkumar, a Software Engineer in the Azure Kubernetes Service team, who works on Node Lifecycle and Kubernetes Versioning, and Brendan, Kubernetes project co-founder and engineering Corporate Vice President of Microsoft Azure OSS and Cloud-native Compute. We talk about what it’s like to work for Microsoft, how mentoring works in practice, and what Kubernetes, Omega, & Borg have to do with it all.
All your network are belong to eBPF
A few weeks ago, Jerod spoke with Liz Rice about the power of eBPF on The Changelog. Today, we have the pleasure of both Liz Rice, Chief Open Source Office at Isovalent & Thomas Graf, CTO & co-founder at Isovalent, the creators of Cilium. Around 2014, Facebook achieved a 10x performance improvement by replacing their traditional load balancers with eBPF. In 2017, every single packet that went to Facebook was processed by eBPF. Nowadays, every Android phone is using it. Truth be told, if it’s network-related and it matters, eBPF is most likely a part of it.
Do the right thing. Do what works. Be kind.
Why are the right values important for a company that changed the way the world builds software? How does pair programming help scale & maintain the company culture? What is it like to grow a company to 3000 employees over 30 years? Today we have the privilege of Rob Mee, former CEO of Pivotal, the real home of Cloud Foundry and Concourse CI. Rob is now the CEO of Geometer.io, an incubator where Elixir is behind many great ideas executed well, including the US COVID response programme.
Two thumbs up for the Cool Wall
Tammer Saleh, founder of Super Orbital, a tiny team of exceptional Kubernetes engineers and teachers, is joining us today to talk about what is cool in the Cloud Native world. Yes, it’s the same Tammer that we had the pleasure of on shipit.show/31 - Is Kubernetes a platform? In today’s episode, we also cover two great blog posts: Zero to GitOps: Terraform and the AWS EKS Blueprints project by Sean Kane Hunting Down an Intermittent Failure in Cilium by James McShane We wrap up with ✨ The Cool Wall of Cloud Native ✨
Bass: the beat drop after Concourse
Our today’s guest spent 4 days building a feature for his side project so that we could ship it together on Ship It!, while recording. The feature is called rave mode, and the context is Bass, an interpreted functional scripting language written in Go, riffing on the ideas of Kernel & Clojure. When the local build runs, you can now press r to synchronise the beats of your currently playing Spotify track with the build output. For a demo, see bass v0.9.0 release. Please welcome Alex Suraci, a.k.a. vito, the creator of Concourse CI and Bass. This episode is dedicated to the late John Shutt, the creator of Kernel. Your ideas continue in Bass. Thank you for getting them out into the world.
KubeVelo 2022
We know that many of you listen to this podcast while running 🏃♀️ or cycling 🚴♂️ Hey Dan! How many of you cycled to a conference? Gerhard knows a single person that cycled 764 miles for 8 days straight from Switzerland to Spain for this year’s KubeCon EU. His name is Johann Gyger, a CNCF ambassador & a cloud consultant at Peak Scale. Johann is a cloud engineer at heart that is all in on sustainability. He is the main reason why Gerhard is super excited to talk about electric cars & Dagger at the Swiss Cloud Native Day this September.
Operational simplicity is a gift to you
Gerhard’s transition to a senior engineer started 10 years ago, when he embraced the vim mindset, functional core & imperative shell, and was inspired to seek simplicity in his code & infrastructure. Most of it can be traced back to one person: Gary Bernhardt, the creator of Execute Program, Destroy all Software and the now famous Wat idea. Few stick around long enough to understand the long-term impact of their decisions on production systems. Even fewer are able to talk about them as well as Gary does.
The ops & infra behind Transistor.fm
Today we talk with two lovely folks from Transistor.fm: Jason Pearl, Senior Software Developer & Jon Buda, co-founder. Gerhard was curious to find out about their setup & how did it change with the launch of the new podcast website builder. After all, you have been hearing us talk about our setup for years, so it was high-time to challenge some assumptions and learn how another team is solving similar problems. TL;DL: keeping it simple is at the root of smooth operations & stable systems.
Kaizen! Post-migration cleanup
In our 6th Kaizen, we talk with Jerod about all the things that we cleaned up after migrating changelog.com from a managed Kubernetes to Fly.io. We deleted the K8s cluster and moved wildcard cert management to Fastly & all our vanity domain certs to Fly.io. We migrated the Docker Engine that our GitHub Actions is using - PR #416 has all the details. We did a few other things in preparation for our secrets plan. Thank you Maikel Vlasman, James Harr, Adrian Mester, Omri Gabay & Owen Valentine for kicking it off in our Slack #shipit channel. Gerhard’s favourite improvement: the new shipit.show domain.
Postgres vs SQLite with Litestream
Ben Johnson, the creator of Litestream, joined Fly.io a few weeks after we migrated changelog.com - episode 50 has all the details. That was pure coincidence. What was not a coincidence, is Gerhard jumping at the opportunity to talk to Ben about Postgres vs SQLite with Litestream. The prospect of running a cluster of our app instances spread across all regions, with local SQLite & Litestream replication, is mind boggling. Let’s find out from Ben what will it take to get there. Thanks Kürt for kicking off this dream.
How to keep a secret
Rob Barnes (a.k.a. Devops Rob) and Rosemary Wang (author of Infrastructure as Code - Patterns & Practices) are joining us today to talk about infrastructure secrets. What do Rosemary and Rob think about committing encrypted secrets into a repository? How do they suggest that we improve on storing secrets in LastPass? And if we were to choose HashiCorp Vault, what do we need to know? Thank you Thomas Eckert for the intro. Thank you Nabeel Sulieman (ep. 46) & Kelsey Hightower (ep. 44) for your gentle nudges towards improving our infra secrets management.
What do oranges & flame graphs have in common?
Today we are talking with Frederic Branczyk, founder of Polar Signals & Prometheus maintainer. You may remember Frederic from episode 33 when we introduced Parca.dev. This time, we talk about a database built for observability: FrostDB, formerly known as ArcticDB. eBPF generates a lot of high cardinality data, which requires a new approach to writing, persisting & then reading back this state. TL;DR FrostDB is sub zero cool & well worthy of its name.
DevOps teams with shared responsibilities
Today we are talking with Maikel Vlasman, technical lead for a large Dutch machine construction company, and a cloud engineer by heart. We cover self-updating GitLab & ArgoCD, Maikel’s thinking behind dev environment setup and a Kubernetes workshop that he is preparing for his team. The goal is to function as a true DevOps team with shared responsibilities. This conversation started as a thread in our community Slack - link in the show notes. Thank you Maikel for being a long-time Changelog listener and for reaching out to us - we enjoyed telling this story.
