9 Best Docker and Kubernetes Resources for All Levels

5 min read

If you’re a developer hunting for Docker and Kubernetes-related resources, then you have finally arrived at the right place. Docker is a suite of software development tools for creating, sharing and running individual containers. it started with a great developer experience. You can just bring up new applications with a simple command; docker run -it alpine. 

As per the Gartner survey report, 70% of organizations will be running multiple containerized apps by 2023. Momentum has definitely grown, and it’s led us to some very humbling discoveries in 2022: Docker is the #1 most loved development tool, and remains the #1 most-wanted tool as per the Stack Overflow’s 2022 Developer Survey

Docker is a containerization platform that packages your application and all its dependencies together in the form of a docker container to ensure that your application works seamlessly in any environment. Docker Container is a standardized unit which can be created on the fly to deploy a particular application or environment. It could be an Ubuntu container, CentOs container, etc. to fulfil the requirement from an operating system point of view. Also, it could be an application-oriented container like a CakePHP container or a Tomcat-Ubuntu container etc.

Let us quickly jump into the top 5 tutorials and resource sites that you might useful, no matter if you are a beginner, intermediate or experience developer.

#1. The Docker Official Documentation

Level: Beginners, Intermediate, Advance

With over 3,700 Github stars and 3,500+ contributors, remains the best resource for learning Docker. You can learn the basics of Docker and understand the benefits of containerizing your applications. The documentation site covers all the leading desktop platforms – Mac, Windows and Linux. It shows how to containerise the app and deploy it to the Clou

#2. The Docker Awesome-Compose Repository


The awesome-compose repository was created to provide a quick and simple way for developers to experience Compose-based setups with different software stacks.  With over 19,500 stars, 3,200 forks, awesome-compose is a popular Docker repository that contains a curated list of Docker Compose samples. It helps developers learn about Docker Compose by providing a starting point for how to integrate different services using a Compose file and to manage their deployment with Docker Compose. This project is hosted over Docker GitHub organization, Inc and publicly open for the community to contribute and submit their compose file.

The setups provided currently in the awesome-compose repository fit mainly in two categories:

  • Application skeletons: useful for kicking off project development. We can find different application skeletons with multiple services already wired together and ready to be launched with docker-compose;
  • Setups with different open-source software stacks. These are not production ready, they are intended mostly for personal/home use or simply for developers to get familiar with them within their local dev environment. 

All samples in the repository are provided as they are, everybody can customize each sample according to their needs.  Do check out this blog that shows how to get started with the sample apps.

#3. The Docker Language-Specific Guides

Level: Intermediate, Advance

For those developers who want to setup their development environment and start containerising their apps considering the best practices, this is the right place to get started with. The language-specific getting started guides walk you through the process of setting up your development environment and start containerizing language-specific applications using Docker. The learning modules contain best practices and guidelines that explain how to create a new Dockerfile in your preferred language, what to include in the Docker image, how to develop and run your Docker image, set up a CI/CD pipeline, and finally provides information on how to push the application you’ve developed to the cloud.

In addition to the language-specific modules, Docker documentation also provides guidelines to build and efficiently manage your development environment. You can find information on the best practices for writing Dockerfiles, building and managing images efficiently, gaining performance improvements by building images using BuildKit, etc. You can also find specific instructions on how to keep your images small, how to persist application data, how to use multi-stage builds, etc.
