Project Introduction

Summary

This project is a tool to build container images from a Dockerfile and push them to a registry. It's designed to be run as a container, typically within a Kubernetes cluster, and does not depend on a Docker daemon.

Problem Solved

Traditional container image building often relies on a privileged Docker daemon, presenting security risks and complexities, especially within containerized CI/CD pipelines running on platforms like Kubernetes. Managing the daemon's state and permissions within transient CI environments is challenging.

Core Features

Daemonless Container Builds

Build container images from a Dockerfile and context without requiring a Docker daemon.

Native Kubernetes Integration

Allows building images from within a Kubernetes cluster, integrating seamlessly with your orchestration.

Flexible Build Contexts and Destinations

Enables builds from various sources like GCS, S3, or local volumes, and pushes to multiple registries.

Use Cases

The daemonless nature and Kubernetes native integration make this project ideal for various build scenarios:

CI/CD Pipeline Integration

Details

Integrate container image building directly into your Kubernetes-native CI/CD pipelines (e.g., using Tekton, GitLab CI on Kubernetes) without needing a sidecar Docker daemon.

User Value

Faster, more secure, and simplified CI/CD workflows.

Secure and Restricted Environments

Details

Build images in restricted or air-gapped environments where access to external Docker daemons is not feasible or permitted.

User Value

Enables container adoption in highly regulated or isolated networks.

Secure Registry Authentication

Details

Use Kubernetes service accounts for authentication to registries, avoiding the need to distribute sensitive credentials widely.

User Value

Improved credential management and reduced risk of exposure.
