Documentation

The Go library documentation is available at go.dev.

What this library is capable of

You can use this library to work with the following objects of the Selectel Domains API:

• zone
• rrset

Getting started

Installation

You can install needed domains-go packages via go get command:

go get github.com/selectel/domains-go

Authentication

To work with the Selectel Domains API you first need to:

• Create a Selectel account: registration page.
• For current version create an Keystone Project Token
• For legacy version create an Selectel Token

❗️IMPORTANT❗️
Selectel Token and Keystone Project Token are different tokens!
Above we mentioned how to get keystone project token, how to obtain selectel token read here

Usage example

package main

import (
	"context"
	"fmt"
	"log"
	"net/http"

	v2 "github.com/selectel/domains-go/pkg/v2"
)

func main() {
	// Keystone project token. Read more in authorization.
	token := "gAAAAABeVNzu-..."

	// Domains API V2 endpoint to work with
	endpoint := "https://api.selectel.ru/domains/v2"

	httpClient := &http.Client{}
	userAgent := "domains-go-v2"
	hdrs := http.Header{}
	hdrs.Add("X-Auth-Token", token)
	hdrs.Add("User-Agent", userAgent)
	// Initialize the Domains API V2 client
	client := v2.NewClient(endpoint, httpClient, hdrs)

	createZoneOpts := &v2.Zone{
		Name: "domains-go-v2.ru.",
	}

	// Create zone
	selectelCreatedZone, err := client.CreateZone(context.Background(), createZoneOpts)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("Created zone: %+v\n", selectelCreatedZone)

	listZonesOpts := &map[string]string{}
	// List zones
	selectelZones, err := client.ListZones(context.Background(), listZonesOpts)
	if err != nil {
		log.Fatal(err)
	}

	for _, zone := range selectelZones.GetItems() {
		fmt.Printf("%+v\n", zone)
	}

	createRrsetOpts := &v2.RRSet{
		Name: "txt.domains-go-v2.ru.",
		Type: v2.TXT,
		TTL:  60,
		Records: []v2.RecordItem{
			// Only for TXT Rrset escaping quotes
			{Content: "\"Hello world!\""},
		},
	}

	// Create rrset type TXT
	selectelCreatedRrset, err := client.CreateRRSet(context.Background(), selectelCreatedZone.ID, createRrsetOpts)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("Created rrset: %+v\n", selectelCreatedRrset)
}

Current version vs Legacy version

Current version is github.com/selectel/domains-go/pkg/v2
Legacy version is github.com/selectel/domains-go/pkg/v1

They are not compatible. They utilize different API and created zones live on different authoritative servers. Zone created in v2 API with current version is entirely new zone, and not available via v1 api and vice versa.

If you are going to create new zone, we strongly recommend to use github.com/selectel/domains-go/pkg/v2.
If you have zones in v1, you still can manage them with github.com/selectel/domains-go/pkg/v1.

Legacy version following objects of the Selectel Domains API v1:

• domain
• record

Current version following objects of the Selectel Domains API v2:

• zone
• rrset

Usage legacy example

❗️IMPORTANT❗️ We are not recommending using this example.

package main

import (
	"context"
	"fmt"
	"log"

	v1 "github.com/selectel/domains-go/pkg/v1"
	"github.com/selectel/domains-go/pkg/v1/domain"
	"github.com/selectel/domains-go/pkg/v1/record"
)

func main() {
	// Token to work with Selectel Cloud project
	token := "gAAAAABeVNzu-..."

	// Domains API V1 endpoint to work with
	endpoint := "https://api.selectel.ru/domains/v1"

	// Initialize the Domains API V1 client
	client := v1.NewDomainsClientV1(token, endpoint)

	createDomainOpts := &domain.CreateOpts{
		Name: "testdomain.xyz",
	}

	// Create domain
	selectelDomain, _, err := domain.Create(context.Background(), client, createDomainOpts)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("Created domain: %+v\n", selectelDomain)

	// List domains
	selectelDomains, _, err := domain.List(context.Background(), client)
	if err != nil {
		log.Fatal(err)
	}

	for _, d := range selectelDomains {
		fmt.Printf("%+v\n", d)
	}

	createRecordOpts := &record.CreateOpts{
		Name:    "share.testdomain.xyz",
		Type:    record.TypeCNAME,
		TTL:     60,
		Content: "origin.example.com",
	}

	// Create domain record
	domainRecord, _, err := record.Create(context.Background(), client, selectelDomain.ID, createRecordOpts)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("Created record: %+v\n", domainRecord)
}
