# Multi-Stage Docker Build: How to Build Production-Ready Docker Image
The source code is for the [short course](https://devteds.com/multi-stage-docker-build)
## Announcement: Course on Kubernetes
> If you want to start deploying your containers to Kubernetes, especially on AWS EKS, [check this course on Kubernetes](https://www.devteds.com/kubernetes-course-aws-eks-terraform) that walkthrough creating Kubernetes cluster on AWS EKS using Terraform and deploying multiple related containers applications to Kubernetes and more. https://www.devteds.com/kubernetes-course-aws-eks-terraform
---
This short course, the [Multi-Stage Docker Build](https://devteds.com/multi-stage-docker-build), is for Developers and DevOps engineers that have some basic knowledge of creating Dockerfile and building docker images, wanting to learn creating multi-stage Dockerfile to build production-ready docker images. In this free short course, we will step through,
- Dockerizing an exisitng application (a Rails application)
- Not too much into the Rails but give a quick walkthrough for Non-Rails developers
- Build Docker Image (without multi-stage), test and run the container locally
- A short overview of how the Dockerfile will be structured for multi-stage
- Transform the Dockerfile with multi-stage for development environment
- Extend to add more stages and build final, deployable and prod-ready image
- Using the deployable image, run container locally to test the prod-ready image
