Developer-first automation platform

Jackadi

What is Jackadi?

Jackadi is a developer-first distributed task execution platform designed for developers with a plugin system architecture consisting of a manager and agents.

The main motivation is to create a framework where developers write tasks as pure code without abstractions or hidden behaviors. Task writing is meant to be natural and direct.

Key principles:

• Pure Go Approach: Tasks are written as Go code with no hidden behaviors - what you write is what you get.
• No Runtime Dependencies: Tasks have no runtime dependencies on other tasks; all dependencies are resolved at compile-time.
• No Abstractions: Task writing is natural for Go developers with minimal framework-specific knowledge needed.
• Flexible Use Cases: From simple package installation to complex workflows like server management and upgrades.

Features

Feature	Description
Distributed Task Execution	Execute tasks across multiple agents from a central manager.
Plugin System	Extend functionality through custom Go plugins.
Advanced Targeting	Target agents via list, glob, regex, advanced query.
Specs Collection	Gather and store system information from agents.
Security	mTLS, agent acceptance workflow, protection against rogue agents.
Developer-Friendly	Tasks/specs are Go function registered with a simple SDK.
SONiC ready	Developed with SONiC network devices in mind.

Architecture

In a nutshell:

• Agents are connected to a manager via persistent bidirectional gRPC.
• Simple plugin system:
  • All tasks and specs collectors are pure Go functions.
  • The plugin system is based on hashicorp/go-plugin.
  • The SDK is simple and easy to use.
• Tasks results are stored in a local BadgerDB.

Quick demo tour

Quickstart

# Start the manager
manager --mtls=false

# Start an agent
agent --id="agent1" --mtls=false

# Accept the agent connection (if not using auto-accept)
jack agents list
jack agents accept agent1

# The agent should be now in "accepted" list
jack agents list

# Check agents health
jack agents health

# Run a task
jack run agent1 cmd:run "echo hello"

Write my first plugin

Create a Go project

package main

import "github.com/jackadi-io/jackadi/sdk"

func Hello(name string) (string, error) {
	return fmt.Sprintf("Hello %s!", name), nil
}

func main() {
	tour := sdk.NewCollection("tour")
	tour.MustRegisterTask("hello", Hello).WithDescription("Greetings.")
	sdk.MustServe(tour)
}

Compile the plugin

CGO_ENABLED=0 go build -o tour .

Put the plugin in the manager

Copy the file in the manager /opt/jackadi/plugins directory.

Synchronize the plugin to the agent

jack run agent1 plugins:sync
