How to learn to use docker?

Question

Docker

Just started exploring this environment. There are enough tutorials on the Internet, like "create an image, make a container, enter a command, everything works." Maybe someone knows a tutorial or a merged course where the theory is analyzed in more detail?

Answer 1

Everything, of course, depends on the level at which you want to learn docker, but the official Get Started is more than enough for basic understanding and use. https://docs.docker.com/get-started/ There you will build the image, raise the container and even push everything into the remote. Advanced things can be found in the same place, if necessary, but I don’t advise you to bother with it too much. If you know that you won't have to work hard with this or will work with basic commands, then you will only waste time. As a rule, for typical tasks (like raising wordpress) there are already ready-made guides, after reading get started I recommend referring to them, but already with an understanding of the matter.

Answer 2

To learn how to swim, you have to swim. If you don't have tasks for a work/pet project that needs docker, it's useless to learn it. You will still forget. There are courses, not even merged ones. For example https://stepik.org/course/1612/ - the first part is devoted to the basics of docker. But I repeat, there are no real tasks - it is useless to teach technology.
