About:
Rockcraft is a command-line tool designed to build OCI-compliant container images using a declarative YAML format similar to Snapcraft and Charmcraft. It simplifies the process of defining image layers, dependencies, and build steps for creating lightweight, secure container images. The tool integrates with the Ubuntu ecosystem, enabling developers to leverage existing snaps and charms for rapid container image creation.

Key Features:

Declarative YAML configuration for image builds
Integration with Snapcraft and Charmcraft ecosystems
Support for OCI-compliant image output
Built-in support for Ubuntu base images
Simplified layer management and dependency resolution

Use Cases:

Building lightweight container images for IoT and edge devices
Creating custom OCI images for Ubuntu-based applications
Migrating snap-based applications to containerized environments

Alternatives:

Docker – Docker uses Dockerfile imperative syntax, while Rockcraft uses declarative YAML similar to Snapcraft
Buildah – Buildah provides lower-level OCI image building, Rockcraft offers higher-level abstractions with Ubuntu ecosystem integration
