Continuous Integration Continuous Delivery/Deployment (CICD) is a very important part of modern-day software release processes. As a matter of fact, you can not survive as a DevOps Engineer without a good understanding of CICD.

This course is designed for web developers and beginner DevOps engineers who want to learn how to deploy a Django application to production, using the best practices of Continuous Integration and Continuous Deployment/Delivery (CICD).

The course covers the use of Git, GitLab, Jenkins and Docker, to build and deploy a full-fledged Django application. and to create a fully functional CICD pipeline.

By the end of this course, you will have learned

  • how to deploy a Django application to production and to any other environment,

  • How to redeploy the same application using deploy scripts, and how to design a functional CICD pipeline with Gitlab and Jenkins and later with GitLab CI.

  • How to collaborate on projects using GitLab. This a must-have skill if you want to work in an organization that has multiple developers, working on a project.

  • How to dockerize Django development environments.

  • How to create and configure virtual machines on your personal computers, so you will be able to practice without the fear of being charged by a cloud service provider.

  • And more.

Everything we'll do will be hands-on and straight to the point.

If you are seeking a job as a Developer or a DevOps Engineer without any professional experience yet, this course is a must for you because, by the end of it, you will have moved from zero experience to at least a year of experience with the tools taught in the course.
