Docker is a powerful tool, however learning how to use it the right way could take a long time especially with the rapidly growing ecosystem of containers which could be confusing, that is why I had the idea to start writing Painless Docker
Through this book, the reader will learn and master Docker and a great part of its ecosystem and among other things, the reader will learn how to create his own Docker monitoring system, that’s why I created DoMonit as a poc for this part of the book.
The purpose of this post is to introduce DoMonit: an API wrapper for Docker built to simplify monitoring specific Docker metrics using Python.
Monitoring gives you a visibility about your infrastructure. Running production without monitoring is not recommended at all.
The same thing is applied to running Docker in production: Monitoring is needed especially if you have a lot of critical applications running containers.
Running Linux systems in production for more than 10 years, I deployed and tested many infrastructure and production monitoring systems.
