CH-3.1.3 – Understanding Docker Images and Layers | AWS EKS Security Masterclass with OWASP EKS Goat

Docker images are built in layers, like a layered sandwich. Each instruction in a Dockerfile creates a new layer. These layers are cached and reusable, which makes builds faster and saves disk space and bandwidth. In this video you will: Understand what a Docker image is and why images are built in layers Learn how Dockerfile instructions map to image layers Build a simple image (Alpine + curl) using docker build -t List images with docker images and validate the build Inspect image layers using docker history Modify a Dockerfile and observe layer caching during rebuilds Run the image to confirm behavior changes (curl --help vs curl --version) Inspect layers visually using the open-source dive tool (Optional) Tag and push an image to Docker Hub This chapter is part of the AWS EKS Security Masterclass on PeachyCloudSecurity YouTube by TheShuklaDuo (Anjali & Divyanshu).
