Ep 177: Is Swarm at EOL? (audio podcast) (YouTube video)
I've been a big fan of Swarm since it was launched over a decade ago and I've made multiple courses on it that people find useful. We recently got some news out of Mirantis that might be bad news. So, I talked about it on my live stream.
NOTE: Since this video was published, I've had multiple people from Docker and Mirantis reach out telling me that Swarm still has a future, so I'm getting more details and hope to make an update to this prediction above. Stay tuned!
👋 New Docker Mastery Videos on ENTRYPOINT & SHELL 🤩
We launched a new Section in Docker Mastery - my first major update in 2025.
If you're already a Docker Mastery student, jump into the new section now.

In this new Section, I dig deep into how ENTRYPOINT works in Dockerfiles, and how it works with both CMD and SHELL statements for making custom CLI tools and advanced container startup scripts. You’ll also learn how to change shells in Docker builds with SHELL, and how Shell and Exec forms work in everything.
This section comes with a quiz, a custom cheat sheet on “Buildtime vs. Runtime” and “Overwrite vs. Additive,” tons of resource links, and two assignments. I’ve also improved the production quality, with more visuals, diagrams, and highlights to help the new knowledge stick!
Here’s an example of one of the cheat sheets you can download in the course resources.
