If I understood correctly, Docker is a software to maintain containers. Containers are ready to go images that can run on top of your base os, like virtualisation but in a more direct way, for exemple by sharing the kernel with the os, making it lighter and way more efficient than full virtualisation
Flar car, wide man lol. Looking at the texts it doesn’t look like they are that warped so I don’t think the image is, or at least not too much
