How to use Compose in Docker

I believe many inexperienced people don't know what to do about how to use Compose in Docker. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

Compose is a tool software developed by Docker company, which can manage multiple Docker containers to form an application. You need to define a configuration file docker-compose.yml in YAML format and write the invocation relationship between many containers.
