Container Images Deep Dive #docker #devops #softwaredevelopment

Containers are everywhere — from local tools to production systems, including serverless, AI, etc. And then we have the images — have you ever wondered what a container image really is? We dive into OCI (Open Container Initiative) Images:

What really makes an image an image
How to pull or push an image
What is a blob, a manifest
What is a tag, and what is the relationship between tags and images
How are multi-arch images made
How can we store other types of information, such as SBOM, provenance attestations

We start by building an image and then explore the internal of the image and its relationship to registries. In the end, you will have a better understanding of what an image really is, including the limitations and the possibilities to extend it.
