I've seen Docker mentioned everywhere, but their GitHub page doesn't offer a clear explanation. Can anyone break down what Docker actually is and why it's so popular?

Docker is like a lightweight virtual machine that allows you to run applications in isolated environments called containers. Unlike traditional VMs that are heavy and require a complete OS, Docker uses the host OS kernel, making it much more efficient. So, you can run software without worrying about different dependencies and versions across various machines—just set it up once and share it around!
So it's kind of like a mini environment that keeps everything together? That's pretty cool!
