Merobox CLI

A Python CLI for managing Calimero nodes (Docker or native) and orchestrating YAML workflows.

Full documentation: https://calimero-network.github.io/merobox/

Quick Start

Installation

PyPI (recommended):

pipx install merobox

From source:

git clone https://github.com/calimero-network/merobox.git
cd merobox
pipx install -e .

Basic Usage

# Start Calimero nodes
merobox run --count 2

# Start with auth service (Docker mode)
merobox run --auth-service

# Start with embedded auth (binary mode)
merobox run --no-docker --binary-path /path/to/merod --auth-mode embedded

# Pass extra arguments straight to `merod run` (binary mode only)
merobox bootstrap run workflow.yml --no-docker --binary-path ./merod \
  --merod-args="--sync-strategy delta --state-sync-strategy hash"

# Check node status
merobox health

# Execute a workflow
merobox bootstrap run workflow.yml

# Stop all nodes
merobox stop --all

Example Workflow

name: "Hello World"
nodes:
  count: 2
  prefix: "node"

steps:
  - name: "Install App"
    type: "install_application"
    node: "node-1"
    path: "./app.wasm"
    outputs:
      app_id: applicationId

  - name: "Create Context"
    type: "create_context"
    node: "node-1"
    application_id: "{{app_id}}"
    outputs:
      ctx_id: contextId

  - name: "Call Method"
    type: "call"
    node: "node-1"
    context_id: "{{ctx_id}}"
    method: "hello"

Features

Node Management — Start, stop, and monitor nodes in Docker or as native processes
Workflow Orchestration — ~100 step types for complex multi-step YAML workflows
Remote Nodes — Connect to remote Calimero nodes with user/password or API key auth
Auth Integration — Traefik proxy (Docker) or embedded JWT auth (binary mode)
Fuzzy Testing — Long-duration randomized load tests with weighted operations
pytest Integration — cluster() and workflow() context managers for test harnesses

Requirements

Python: 3.9 – 3.11 (3.12+ not supported due to py-near / ed25519 dependency)
Docker: 20.10+ (for Docker mode)
OS: Linux, macOS (Windows via WSL only)
