Hey everyone! I'm looking for some solid recommendations for beginner-friendly courses to help me get started with Docker. I'm working on a project where I need to create containers for ROS2 nodes, and I really want to grasp the concepts rather than just following instructions blindly, like using ChatGPT. I've seen terms like "entrypoint.sh" and "Dockerfile," and I have an idea of what they're about, but I'm not sure how to build everything from scratch. Any advice would be awesome!

In addition to documentation, try engaging with learning tools that explain concepts. Instead of just asking for code, prompt a tool to explain the Docker workings or architecture. It sounds like you want a broader understanding, so this could help!

While the official docs are great, I suggest also searching for beginner courses in forums like Reddit. There are tons of resources that can help clarify the concepts you might be confused about, especially if you're wanting to understand the flow and purpose of Docker.
