ovmlayer-rootfs

This repository builds multi-architecture (amd64/arm64) rootfs tarballs and container images for Oocana runtime environments.

Artifacts

1. Base Rootfs (rootfs-base.yml)

Minimal Ubuntu-based rootfs with Zsh shell for ovmlayer layer testing.

• Purpose: Basic Linux container foundation for oocana-rust layer feature tests
• Contents: Minimal Linux userspace + Zsh
• Trigger: Tags matching base-rootfs*

2. Server Rootfs (rootfs-server.yml)

Server base rootfs built from upstream ghcr.io/oomol/server-base foundation image.

• Purpose: Foundation layer for studio runtime builds
• Trigger: Tags matching server-base*

3. Executor Layer (layer-executor.yml)

Python and Node.js executor dependencies layer for workflow execution.

• Purpose: Run Python and Node.js blocks in oocana-rust layer feature
• Contents: Python executor + Node.js executor (without oocana CLI)
• Trigger: Tags matching executor-layer*

4. Runtime Image (image-runtime.yml)

Complete Oocana runtime container image with CLI and ovmlayer.

• Purpose: Run oocana directly without layer feature
• Contents: oocana CLI + ovmlayer (executor layers are separate tar artifacts)
• Registry: ghcr.io/oomol/oocana-runtime

Workflows

Workflow	Purpose	Trigger
rootfs-base.yml	Build minimal base rootfs	base-rootfs* tags
rootfs-server.yml	Build server foundation rootfs	server-base* tags
layer-executor.yml	Build Python/Node.js executor layer	executor-layer* tags
image-runtime.yml	Build runtime image with CLI and ovmlayer	Push to main or workflow_dispatch
layer-package.yml	Package custom layers (reusable workflow)	Called by other repos
test-actions.yml	Test all GitHub Actions	PR or workflow_dispatch

Usage

Run Oocana with Runtime Image

docker run -d --name oocana ghcr.io/oomol/oocana-runtime:latest
docker exec -it oocana mosquitto -d -p 47688
docker exec -it oocana oocana run <flow-yaml>

Build Custom Layer

Use layer-package.yml as a reusable workflow in your repository to create custom package layers.
