Hello everyone!
As the advent of Docker comes to an end, I wanted to share some resources that I have found helpful in my journey. I thought you might like them too.
How Containers Work by Julia Evans
Julia Evans’ magazine about containers Absolutely a gem! This is a fun, illustrated guide that breaks down complex container concepts into easy-to-understand pieces. Julia has a unique talent for making technical topics approachable and enjoyable. The magazine covers everything from namespaces and cgroups to container runtime internals, all with delightful hand-drawn illustrations. If you’re a visual learner or just want a new perspective on container technology, this is a must-read, although it’s only available if you pay!
Docker files
this Docker official documentation A comprehensive guide to all things Docker. While this may seem obvious, it’s worth emphasizing that this is one of the best-maintained technical documents out there.
Docker source code
For those interested in the more in-depth technical aspects, Docker’s source code is available in two main repositories:
Build Kit It is the engine behind the Docker build system. It’s an interesting look at how Docker images are built, and has the following features:
- Concurrency dependency resolution
- Efficient caching mechanism
- Advanced construction primitives
Moby It is the open source foundation of Docker Engine. Digging deeper into this code base will help you understand:
- Container runtime implementation
- Image management
- Networking architecture
- storage driver
I spent a lot of time reading the source code of Docker and BuildKit. If you want to understand how Docker works under the hood, I highly recommend it!
Docker Registry Specification
this Delivery specifications This is a must-read if you want to understand how Docker images are stored and distributed, but beyond that it’s not that interesting.
OCI specification
this Open Container Initiative (OCI) Specification Defines industry standards for container formats and runtimes. This is crucial reading for:
- Understand container image formats
- Understand container runtime requirements
- Mastering standardization for container portability
- Discuss the technical requirements of container platforms
These specifications form the basis of modern container technology and are essential reading if you want to gain a deeper understanding of how containers work on a standardized level.
My blog 🙂
Well, can’t ignore my own blog, right? I write a lot about Docker, mostly real world examples and such.
See you for the last time tomorrow
