When you are writing your paper or documents on LaTeX, you have to face an inevitable issue, that is compiling you LaTeX code to pdf. As for beginners of researchers, they may choose to use Overleaf, it is very simple to use, but when your documents or paper are becoming more and more bigger, overleaf will charge to you. So why don’t I compile it by myself?
In this section, I will record how to compile LaTeX code in local.

1. Prepare your LaTeX code.

1.1. Edit with your VScode(Strongly recommend by me)

Download and install extensions of LaTeX in VScode plugin store.
You can find it at here

Edit your LaTeX code.

1.2 Download whole folder(project) from overleaf.

2. Prepare Compile Environment.

Before we start this section, we have to know, in order to compile LaTeX, we have to use tex compile tools, and there are some different distributions of tex[1]:
MiKTeX for Windows
TeX Live for Linux and other UNIX-like systems
MacTeX redistribution of TeX Live for macOS
teTeX for Linux and other UNIX-like systems; it is no longer actively maintained now
proTeXt is based on MiKTeX
In this section, I will introduce how to use TeX live, it can solve majority case.

2.1. Docker(Strongly recommend)

Why I recommend you use docker is out of some reasons:
Simple install
Simple remove
Simple use
To speak of, texlive is very storage-consuming, it is about 5.14 GB.

2.2.1. Download and install docker

If you have some problems about network, you need to set proxy for docker:
How to set network proxy for Docker

2.2.2. Pull TeX Live

If you are in China mainland, you should first master how to use TUN/proxy pattern to login your docker account. Besides, you also can use Podman. I also recommend you to study how to use podman and what difference are there between these to container tools[2].
Just use:

docker pull texlive/texlive

2.2.3. Compile your LaTeX code.

We have no need to start a container, just run it, after compiling, container will be deleted automatically.
pdflatex: First compile your code with pdflatex.

docker run --rm -v ${PWD}:/workdir texlive/texlive pdflatex main.tex

bibtex: to tackle cites:

docker run --rm -v ${PWD}:/workdir texlive/texlive bibtex main

pdflatex: again to merge cites:

docker run --rm -v ${PWD}:/workdir texlive/texlive pdflatex main.tex

2.2.4. Example Usage

You should place .tex, .cls if exists, and .bib if exists at the same directory. Just as follows.

Conduct command above:

Result:
There will be a main.pdf for you:
