What does good DevOps look like?

This week Gerhard is chatting with Romano Roth, Head of DevOps at Zühlke, a company founded by Gerhard Zühlke in 1968. Nowadays they help companies all over the world build, ship and run anything from factory robots, to AI assistants in complex regulatory environments, and even medical devices that perform autonomous robotic surgery.

When Romano is not leading a team of 30 software engineers that specialise in operations, infrastructure and cloud, he is one of the organisers of DevOps Days Zürich, and also the DevOps Meetup group, which is how Gerhard and Romano met in 2019.

Having started his career as a .Net developer back in 2002, Romano had his fair share of dev and ops challenges, and he always enjoys seeing real business value delivered continuously in an automated way. In recent years, Romano’s perspective broadened, and now he sees DevOps realities across many companies. If you are curious about what good DevOps looks like, and what are the real challenges, then Romano has some good insights for you.

A universal deployment engine

In today’s episode, Gerhard is talking to Sam Alba, Docker’s first employee, and Solomon Hykes, the Docker co-founder. Together with Andrea Luzzardi, they are the creators of Dagger, a universal deployment engine that trades YAML for CUE, and uses Buildkit as the runtime.

Why? Because we should stop rewriting the same application deployment logic in scripts, makefiles or continuous delivery configuration. That’s right, this is the YAML vaccine that we have all been waiting for.

Gerhard believes that one day, Dagger will become just as meaningful for application delivery, as Docker is today for application code.

Why Kubernetes?

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, a Phoenix monolith, on Kubernetes, what do I think? Join our discuss and find out!

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!

Continuous Delivery for Kubernetes

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.

Building fully declarative systems with Nix

Vincent Ambo –the person behind,, and a former Google engineer– shares his take on monorepos, Nix, and fully declarative systems without any Flux, Argo or Kubernetes.

While the tooling is impressive, it’s the principles behind it that captivated Gerhard’s imagination. Vincent has a rather interesting take on the monorepository idea, including one change - one version - one deploy. There are a lot of interesting links in the show notes, including all the code that Vincent uses to manage infrastructure.

As a result of this conversation, Gerhard is running Nix on one of his Macs, and also started experimenting with his first NixOS production instance.

Real-world implications of shipping many times a day

This week Emile Vauge, founder & CEO of Traefik, joins Gerhard to share a story that started as a solution to a 2000 microservices challenge, the real-world implications of shipping many times a day for years, and the difficulties of sustaining an inclusive and healthy open-source community while building a product company.

Working every day on keeping the open-source community in sync with the core team was an important lesson. The second learning was around big changes between major versions.

The journey from Travis CI to Circle CI, then to Semaphore CI and eventually GitHub Actions is an interesting one. The automation tools inspired by the Mymirca ant colony is a fascinating idea, executed well. There is more to discover in the episode.

🎄 Merry Shipmas 🎁

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 GitHub repository will help you just as much as they will help our 2022 setup.

🎄Merry Shipmas everyone! 🎄

Assemble all your infrastructure

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 2022 setup. Listen to what Jared & Dan think, and then let us know your thoughts too.
