Courses / books / videos on administering web servers - which ones do you recommend?

Question

Nginx

And for many years now I have been making websites, both on Bitrix and purely on php. In the process, I had to self-teach myself a little web administration, that and that.
I would like to fill in all the gaps on this topic.
especially here is what interests us:
we make small projects on ordinary virtual servers for rent.
But from the developers of large projects I heard such words as docker, container, etc.
I read a little about containers (such as an article on a wiki, such a level).
But where is it well written about it? Read manuals?

Answer 1

This topic is primarily related to the knowledge of operating systems. Read Related Books
When it comes to specific tools and how to use them, start by automating deployment and infrastructure deployment using ansible and terraform tools. Next, migrate local development to docker-composer. Then it will be possible to drag the docker into production (using the same ansible in the primitive case). You can read about docker here https://guides.hexlet.io/docker/

Answer 2

Docker is needed in very rare cases, if you are a SaaS that is based on this container
nginx-fpm-postgres - enough for the eyes
A large project can do without containers and be more stable and scalable
