Setup snapshot

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

FYY Sandbox Images

OCI container images for running AI Agents in sandboxed environments — part of the FYY decentralized skill marketplace.

Pre-built images with FYY CLI and popular Agent frameworks — ready to use with any OCI-compatible runtime (Docker, Podman, containerd, gVisor, Kata Containers, and more).

Available Images

| Image | Tag | Description | Architectures | |-------|-----|-------------|---------------| | Base | latest | fyy CLI + Python 3.12 + Node.js 22 LTS | amd64, arm64 | | CrewAI | crewai | CrewAI framework + fyy CLI + example agent | amd64, arm64 | | LangGraph | langgraph | LangGraph framework + fyy CLI + example agent | amd64, arm64 | | DeerFlow | deer-flow | DeerFlow multi-agent framework (LangGraph-based) + fyy CLI + example agent | amd64, arm64 |

Versioned tags are also available (e.g. v1.0.0, crewai-v1.0.0).

Quick Start

# Pull the base image
docker pull feiyueyun/fyy-sandbox:latest

# Run and connect to an FYY network
docker run -it feiyueyun/fyy-sandbox:latest fyy network join --authkey=tskey-auth-xxx

# Use a framework-specific image
docker pull feiyueyun/fyy-sandbox:crewai
docker run -it feiyueyun/fyy-sandbox:crewai

# DeerFlow multi-agent framework
docker pull feiyueyun/fyy-sandbox:deer-flow
docker run -it feiyueyun/fyy-sandbox:deer-flow

What's Inside

Base Image (`feiyueyun/fyy-sandbox:latest`)

fyy CLI — pre-installed at /usr/local/bin/fyy
Python 3.12 — with pip3 and venv
Node.js 22 LTS — with npm
System tools — curl, git, ca-certificates
Non-root user — runs as fyy (UID 1000) by default
Sandbox marker — FYY_SANDBOX=1 environment variable

Framework Templates

Each template extends the base image with a specific AI Agent framework and includes a runnable example agent project at /home/fyy/example-agent/.

Runtime Detection

The base image sets ENV FYY_SANDBOX=1, which tells the fyy CLI it is running inside a Layer-1 sandbox. When detected, the Layer-2 Skill Process Sandbox (gVisor) automatically downgrades to process-level isolation, since gVisor cannot nest inside a container.

Three detection methods are available (in priority order):

FYY_SANDBOX=1 environment variable — most reliable, works with all OCI runtimes
/.dockerenv file — Docker-specific
/proc/1/cgroup container markers — Linux kernel-level

Building Locally

# Build base image (release mode — downloads fyy from GitHub Releases)
make build-base

# Build base image (dev mode — cross-compiles fyy from ../fyy-src)
make dev-prepare
BUILD_MODE=dev make build-base

# Build all images
make build-all

# Run smoke tests
make smoke-test

# Run Trivy security scan
make trivy-scan

See make help for all available targets.

Image Signing

Published images are signed with Cosign using keyless signing (Sigstore Fulcio + Rekor).

# Verify image signature
cosign verify feiyueyun/fyy-sandbox:latest \
  --certificate-identity=https://github.com/feiyueyun/fyy-sandbox-images/.github/workflows/build-and-publish.yml@refs/tags/v1.0.0 \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com

fyy CLI License

fyy CLI is closed-source and free to distribute. This does not conflict with the BSD 3-Clause license of the Dockerfiles and build scripts in this repository — similar to how Docker images can pre-install proprietary tools like curl while the image definition remains open source.

Integration Guides

See fyy-sandbox-guides for integration with popular sandbox runtimes (E2B, Daytona, Devcontainer, Kata, Firecracker, Docker, gVisor, Kubernetes).
