Bocker Project Description

What is the project about?

Bocker is a simplified implementation of Docker, written in approximately 100 lines of Bash. It aims to provide core containerization functionality similar to Docker.

What problem does it solve?

It provides a lightweight and understandable way to create and manage containers, offering an alternative to the full Docker implementation. It can be used for educational purposes to understand the underlying principles of containerization.

What are the features of the project?

Image pulling (bocker pull).
Listing images (bocker images).
Running containers (bocker run).
Listing running containers (bocker ps).
Viewing container logs (bocker logs).
Committing container changes to a new image (bocker commit).
Removing containers and images (bocker rm, bocker rmi).
Basic networking for containers.
Resource limits (CPU and memory) using cgroups.
Limited support for building images.
docker exec

What are the technologies used in the project?

Bash scripting
btrfs filesystem
Linux networking tools (iproute2, iptables)
cgroups (libcgroup-tools)
util-linux
coreutils
curl

What are the benefits of the project?

Simplicity: The small codebase makes it easy to understand how containerization works.
Lightweight: It has fewer dependencies than the full Docker implementation.
Educational: It serves as a good learning tool for understanding containerization concepts.

What are the use cases of the project?

Learning about containerization internals.
Experimenting with container technology in a simplified environment.
Potentially serving as a base for building more specialized container tools.
Running basic containerized applications.
