Stop Using Docker. Use Open Source Instead.


Stop Using Docker.

Use Open Source Instead.

You know how people say "Google it" to describe any online search?

Well, the same thing happened with Docker - it became synonymous with containers.

But times are changing, and your wallet (and lawyer?) might thank you for paying attention, especially if you're using Docker for commercial purposes.

Four years ago, Docker made a move that shocked the container world, everyone saw it coming from miles away, but ignored it, until it became real - they started charging for CLI usage and Docker desktop for commercial use.

Suddenly, companies using DockerHub found themselves hitting rate limits, bringing their workflows to a grinding halt unless they paid up.

The problem isn't just about DockerHub; if you're running Docker Desktop on your Mac for commercial purposes without a license, you might be breaking the law.

Enter Podman

Described as "the best free and open source container tool system." Podman is Docker's more efficient, cost-free younger sibling.

It does everything Docker does, a fully compatible drop-in alternative, but with some impressive extras under the hood.

The most significant difference? It's daemon-less and can run rootless containers, meaning better security from the containers perspective not being able to elevate permissions and simpler operation, without a resource hungry daemon in the background.

Native Pod support

What makes Podman particularly interesting is its native support for pods, running multiple containers - a feature Docker doesn't have.

If you're working with Kubernetes or planning to, this is a game-changer.

Imagine being able to group multiple containers together, have them communicate seamlessly over localhost, and even generate Kubernetes YAML files directly from your local setup, ready for K8s. That's what Podman offers out of the box.

The transition is surprisingly painless

Your existing Docker commands work with Podman - just replace 'docker' with 'podman' in your commands, or even set 'alias docker=podman' in your rc file.

But that's not all

Need a UI? Podman Desktop provides everything Docker Desktop does, plus additional features like built-in Kubernetes integration and cluster management tools.
YES: it comes with a built-in Kubernetes dashboard!

For enterprises, the benefits are even more compelling.

No more worrying about commercial licensing or rate limits.

No more unexpected bills or legal concerns.

Just straightforward, efficient container management with the added benefit of better Kubernetes integration.

Whether you're a solo developer or part of a large team, Podman, being an open source, free drop-in replacement, provides the tools you need without the strings attached, especially if you're using Kubernetes.

The container world is evolving, and it's time to adapt.

Make the switch to Podman, and join the growing community of developers.

I Was DEFINITELY Using The Wrong VPS Setup When was the last time you thought up running something on a server? It doesn't have to be something fancy. A side project. A utility. An open source that you always wanted to run on your own but just too lazy to get it off the ground so you. I certainly have. Even when I needed a local server, my immediate thought was "sure, I can just setup and K8s cluster on my raspberry pie an put whatever I want there" 🤦 After years of advocating for complex...
