• Go to Orchestrator Dashboard, switch network to Swan Chain Mainnet.

• Login with your wallet.

• Click the user icon on the top right.

• Click Show API-Key -> New API Key

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.small",
	})
	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)
}
