What are the best free platforms to learn Docker?

You should definitely check out Docker’s official labs! They’re a solid place to start and offer hands-on practice. Once you're familiar, Minimus is a fantastic tool for diving into secure, minimal container images while teaching you some best practices.

For something a little different, you could buy a course on Udemy. They often have deals, and I've seen courses on Docker and Kubernetes for about 20 bucks!

Honestly, the best way to learn is usually from the source material, like the official docs. Just remember that it's important to find resources that suit your learning style!

Have you considered the official Docker documentation? It's a great resource! But I get that sometimes having a step-by-step guide can make it easier to understand the basics without feeling overwhelmed. Visual content can be super helpful!
