Deploying with Swan SDK

The Swan SDK is a toolkit designed to simplify interactions with the Swan Chain Network Resource. It provides a streamlined interface for creating and managing computational tasks, retrieving hardware information, processing payments, and monitoring task statuses.

For more sample tutorial, please refer to Python Swan SDK Samples or Go Swan SDK Samples.

Get Swan API Key

To use swan-sdk, a Swan API key is required. Steps to get an API Key:

• Go to Swan Console, switch network to Swan Chain Mainnet.

• Login with your wallet.

• Click API Keys -> Generate API Key

Quick Start

Python

Installation

To use Python Swan SDK, you first need to install it and its dependencies. Before installing Swan SDK, install Python 3.8 or later and web3.py(==6.20.3).

Install the latest Swan SDK release via pip:

pip install swan-sdk

Or install via GitHub:

git clone https://github.com/swanchain/python-swan-sdk.git
cd python-swan-sdk
pip install .

Using Python Swan SDK

To use Python Swan SDK, you must first import it and indicate which service you're going to use:

import swan

swan_orchestrator = swan.resource(api_key='<SWAN_API_KEY>', service_name='Orchestrator')

Now that you have an Orchestrator service, you can create and deploy instance applications as an Orchestrator task with the service.

result = swan_orchestrator.create_task(
    repo_uri='https://github.com/swanchain/awesome-swanchain/tree/main/hello_world', # Or your own repo URI
    wallet_address='<WALLET_ADDRESS>',
    private_key='<PRIVATE_KEY>',
    instance_type='C1ae.medium'
)
task_uuid = result['task_uuid']

Then you can follow up task deployment information and the URL for running applications.

# Get task deployment info
task_deployment_info = swan_orchestrator.get_deployment_info(task_uuid=task_uuid)
print(task_deployment_info)

# Get application instances URL
app_urls = swan_orchestrator.get_real_url(task_uuid)
print(app_urls)

Go

Installation

Go Version

go-swan-sdk requires Go version 1.21 or above.

Using go-swan-sdk

With Go's module support, go [build|run|test] automatically fetches the necessary dependencies when you add importin your project:

import "github.com/swanchain/go-swan-sdk"

To update the SDK use go get -u to retrieve the latest version of the SDK:

go get -u github.com/swanchain/go-swan-sdk

Quickstart

To use go-swan-sdk, you must first import it, and you can create and deploy instance applications quickly.

package main

import (
	"github.com/swanchain/go-swan-sdk"
	"log"
	"time"
)

func main() {
	client, err := swan.NewAPIClient("<YOUR_API_KEY>")
	if err != nil {
		log.Fatalf("failed to init swan client, error: %v \n", err)
	}
	task, err := client.CreateTask(&swan.CreateTaskReq{
		PrivateKey:   "<PRIVATE_KEY>",
		RepoUri:      "https://github.com/swanchain/awesome-swanchain/tree/main/hello_world",
		Duration:     2 * time.Hour,
		InstanceType: "C1ae.medium",
	})
	taskUUID := task.Task.UUID

	// Get task deployment info
	resp, err := client.TaskInfo(taskUUID)
	if err != nil {
		log.Fatalln(err)
	}
	log.Printf("task info: %+v \n", resp)

	//Get application instances URL
	appUrls, err := client.GetRealUrl(taskUUID)
	if err != nil {
		log.Fatalln(err)
	}
	log.Printf("app urls: %v \n", appUrls)
}
