Kaizen! We are flying ✈️

This is our 5th Kaizen where we talk about the next improvement to changelog.com: we are now running on Fly.io and our PostgreSQL is managed. This is a migration that many were curious about, including Simmy de Klerk, the person that requested this episode.

After migrating all our media files to AWS S3 (check episode 40), we thought that this part was going to be easy. Plan met reality. Pull request 407 has all the details.

We want to emphasise the type of partner relationships that we seek at Changelog & why they are important to us, as well as to our listeners. Honeycomb & Fly embody the principles that we care about, and Gerhard thinks that we are currently missing a Kubernetes partner.

A simpler alternative to cert-manager

Nabeel Sulieman, Senior Software Engineer at Vercel, talks about KCert, a simpler alternative to cert-manager that he built. Gerhard tried it out, and he thinks that Nabeel is onto something. If you want to see the video that they recorded, ping us on Twitter or Slack.

We love this story, especially the long-term approach of working on something that one truly believes in, and the only reason is because it’s fun. The world needs more people like Nabeel, and we hope that this episode inspires you to go all out, and do just that.

Today’s conversation with Kelsey Hightower showed Gerhard what he was missing in his quest for automation and Kubernetes. The fundamentals that Kelsey shares will most certainly help you level up your game.

This is a follow-up to the last 45 seconds of the Kubernetes documentary.

Oh, and we finally cleared where we should run our changelog.com PostgreSQL database 🙂

In this week’s episode Cameron Dutro, a software engineer at GitHub, Ship It listener and someone with an extraordinary attention to detail, joins us to talk about Kuby, a convention-over-configuration approach to deploying Rails apps.

The question that we will be trying to answer is what happened to Rails Active Deployment. The path to that promise land is paved with good intentions, but it’s complicated.

This week we have the pleasure of Rich Burroughs, Senior Developer Advocate at Loft Labs and host of the Kube Cuddle podcast.

We talk about multitenancy in Kubernetes and how to run Kubernetes in Kubernetes with vcluster. If you are using KiND, you will find this episode interesting, and maybe even helpful.

We also talk about the role that Kelsey Hightower played in Rich joining the CNCF ecosystem. The key take-away is that people make all the difference.

ADHD is something that Rich thinks about often. Gerhard was curious about the difference between ADHD and burnout, as well as this Twitter thread on re-reading sent emails.

Continuous Delivery for Kubernetes

2022-02-23T12:00:00Z #ops +2 🎧 11,070

In today’s episode, Gerhard is talking to Mauricio Salatino (@salaboy) about the Continuous Delivery for Kubernetes book that he is currently writing.

Mauricio is a Staff Engineer at VMware where he spends most of his time contributing to Knative, an open source platform for running serverless workloads on Kubernetes. Gerhard & Mauricio spent a few months in 2021 working on Knative Eventing, and they both appreciate shipping great software continuously. Mauricio helped ship Knative 1.0.

The from-monolith-to-k8s application used throughout this book has been a few years in the making. It doubles-up as a workshop-style guide for rearchitecting a Java monolith to a Cloud Native architecture running in Kubernetes.

Haunted codebases & complex ops

This week we are talking to Robin Morero, the person behind fabled.se, a DevOps consultancy from Gothenburg, Sweden. Their motto is “move faster and prosper”, which Gerhard prefers to the initial “move fast and break things”.

Fabled works with startups primarily, and after 26 years, Robin has a few interesting insights to share. What do you think, are haunted codebases real? At what point do pull requests become harmful? What about k3s running on KVM as a simple starting point for production? If this reminds you of #7, and the follow-up YouTube stream with Lars, it’s no coincidence.

Where is the cloud native App Store?

2022-01-05T23:30:00Z #ops +2 🎧 10,014

In our first 2022 episode, Alexis Richardson, co-founder and CEO of Weaveworks, is talking to Gerhard about going fully remote, what a great team looks like, and GitOps. While you may have heard of GitOps, now is a good time to check out opengitops.dev.

The most interesting part of today’s conversation is the missing cloud native App Store. While Apple revolutionised the world with the App Store and the iPhone, we don’t yet have something similar for cloud native apps. You may be thinking “But what about OperatorHub?”, or all the Helm registries out there? The registry fragmentation, operator deprecations and lack of curation are not what people have in mind when they think App Store. But there is more to it, so let’s hear how Alexis thinks about this.

Merry Shipmas! This is our special Christmas episode which sums up two months of very early mornings and a few late nights. After many twists and turns, stuff which didn’t work out, as well as pleasant surprises, this is what we ended up with:

  • 🎁 PR #395 - CI/CD Lego set with Guillaume de Rouville & Joel Longtine
  • 🎁 PR #396 - Continuous CPU profiling with Frederic Branczyk
  • 🎁 PR #399 - Auto-restoring Kubernetes clusters with Dan Mangum & Muvaffak Onuş

While we initially intended to have five Christmas presents in total, only three got delivered in time. We planned, worked hard and eventually shipped the best we could just in time for this special Christmas episode. Our hope is that the latest additions to our changelog.com GitHub repository will help you just as much as they will help our 2022 setup.

🎄Merry Shipmas everyone! 🎄

Crossing the platform gap

Play
2021-12-17T14:45:00Z #ops +1 🎧 20,335

In 2014 Gerhard joined CloudCredo, a startup co-founded by Colin Humphreys, Paula Kennedy & Chris Hedley. They stuck together through two acquisitions: Pivotal & VMware. This year, Colin, Paula & Chris co-founded Syntasso, the Platform-as-a-Product startup.

Today they all get together to talk about about what it takes to build a platform team, why Team Topologies is a good conversation starter and why a curated blend of off-the-shelf, composed, and self-created services are required in any organisation operating at scale.

Your hunch is right, all of them used to share the same Pivotal London office with Tammer Saleh, our guest from episode 31. Chris used to win all table tennis matches without even breaking a sweat, and today Gerhard gets his comeback. Touché!

Is Kubernetes a platform?

Tammer Saleh, founder of SuperOrbital and former VP of Engineering at Pivotal, is joining Gerhard to talk about table tennis, remote work, and challenges that teams have with K8s.

Some years ago, both Tammer & Gerhard used to work in the same London office on CloudFoundry, and nowadays they are both into Kubernetes. Tammer and the SuperOrbital team are deeply experienced in this topic, and they help teams at companies like Bloomberg, Shopify, and federal U.S. agencies tackle hard Kubernetes and DevOps problems through engineering and training.

Why do companies need Kubernetes in the first place? Which are the right reasons for choosing it? Is Kubernetes a platform? Gerhard’s favourite: we are doing Kubernetes wrong, but it works better than when we were doing it right, so what’s up with that? This last one was a lot of fun, and we left the entire minute of laughter in at your request. Enjoy!

Gerhard at KubeCon NA 2021: Part 2

In the second set of interviews from KubeCon North America 2021, Gerhard and Liz Rice talk about eBPF superpowers - Cilium + Hubble - and what’s it like to work with Duffie Cooley.

Jared Watts shares the story behind Crossplane reaching incubating status, and Dan Mangum tells us what it was like to be at this KubeCon in person. Dan’s new COO role (read Click Ops Officer) comes up.

David Ansari from VMware speaks about his first KubeCon experience both as an attendee and as a speaker. The RabbitMQ Deep Dive talk that he gave will be a nice surprise if you watch it - link in the show notes.

Dan Lorenc brings his unique perspective on supply chain security, and tells us about the new company that he co-founded, Chainguard. How to secure container images gets covered, as well as one of the easter eggs that Scott Nichols put in chainguard.dev.

This is Gerhard’s first set of interviews from KubeCon North America 2021.

William Morgan shares with us some of the finer Linkerd details, such as the underlying security theme, why native Kubernetes objects are preferable to more CRDs, and the joy of meeting team members in person.

Frederic Branczyk speaks about Parca, a new continuous system profiling tool that uses eBPF to help you understand what is happening on your hosts.

Andrew Rynhard gives us a great Talos OS and Kubespan perspective, and shares some really good follow-up videos on these topics.

The last conversation is with David Flanagan - you know him as Rawkode - about new beginnings. It’s only been less than two months since we’ve had him in episode 18, and he kept really busy. Caleb, his 3 weeks old baby boy, was the youngest attendee at this conference, and some talks made him sleepy, so good job everyone.

Bare metal meets Kubernetes

2021-09-09T21:00:00Z #ops +2 🎧 6,238

In this episode, Gerhard talks to David and Marques from Equinix Metal about the importance of bare metal for steady workloads. Terraform, Kubernetes and Tinkerbell come up, as does Crossplane - this conversation is a partial follow-up to episode 15.

David Flanagan, a.k.a. Rawkode, needs no introduction. Some of you may remember Marques Johansson from The new changelog.com setup for 2019. Marques was behind the Linode Terraforming that we used at the time, and our infrastructure was simpler because of it!

This is not just a great conversation about bare metal and Kubernetes, there is also a Rawkode Live following up: Live Debugging Changelog’s Production Kubernetes 🙌🏻

In this episode, Gerhard follows up on The Changelog #375, which is the last time that he spoke Crossplane with Dan and Jared. Many things changed since then, such as abstractions and compositions, as well as using Crossplane to build platforms, which were mostly ideas.

Fast forward 18 months, 2k changes, as well as a major version, and Crossplane is now an easy choice - some would say the best choice - for platform teams to declare what infrastructure means to them. You can now use Crossplane to define your infrastructure abstractions across multiple vendors, including AWS, GCP & Equinix Metal. The crazy ideas from 2019 are now bold and within reach. Gerhard also has an idea for the changelog.com 2022 setup. Listen to what Jared & Dan think, and then let us know your thoughts too.

Why Cloud Native? What are the guiding principles that you should keep in mind as you are choosing a project from the Cloud Native Landscape? How do you build & ship an app in a Cloud Native way? Katie Gamanji, Ecosystem Advocate @ CNCF and former cloud engineer for American Express, Condé Nast and Microsoft, joins Gerhard to cover these topics in the context of the Cloud Native Fundamentals course that she developed. 15,000 students have already enrolled, and the initial feedback has been great. Tune in if you want to know why you should too, how to do it and when the course will become available for free.

This week on Ship It! Gerhard talks with Lars Wikman (independent Elixir/BEAM software consultant) why sometimes a monolith running on a single host with continuous backups and a built-in self-restore capability is everything that a small team of developers needs. That’s right, no Kubernetes or microservices. After 2 years of running changelog.com, a Phoenix monolith, on Kubernetes, what do I think? Join our discuss and find out!
