Taskcluster Client for Go

A Taskcluster client library for Go.

This package contains a complete client interface to Taskcluster in Go, including pre-defined types for the data structures consumed and produced by the API methods.

Usage

For a general guide to using Taskcluster clients, see Calling Taskcluster APIs.

This library provides the following packages to interface with Taskcluster:

HTTP APIs

AMQP APIs

Setup

Before invoking API methods, create a client object corresponding to the service you wish to communicate with. See the client subdirectories for the list of available packages, each beginning with tc.

The most common case is to use NewFromEnv, reading environment variables for credentials:

import (
	"github.com/taskcluster/taskcluster/v42/clients/client-go/tcqueue"

	tcclient "github.com/taskcluster/taskcluster/v42/clients/client-go"
)
queue := tcqueue.NewFromEnv()

Each client package has a New method that takes explicit configuration, too:

creds := tcclient.Credentials{
    ClientID: "..",
    AccessToken: "..",
}
queue := tcqueue.New(&creds, rootURL)

If the first argument is nil, then the client makes API requests without authentication.

The Credentials struct has an optional list of AuthorizedScopes. This can be used to restrict the scopes for a request,

Calling API Methods

Each client object exposes API methods by their Golang-formatted name. For example, a tcqueue.Queue object has methods like CreateTask and GetArtifact. The calling signature for these methods resemble those in the service reference documentation, with the payload and response data represented by Golang structs.

For example, the CreateTask method is called like this:

import (
	"github.com/taskcluster/taskcluster/v42/clients/client-go/tcqueue"
    "github.com/taskcluster/slugid-go"
)
task := tcqueue.TaskDefinitionRequest{..};
taskId: = slugid.Nice() 
status := queue.CreateTask(taskId, &task)

Complete Godoc documentation of the available methods and types is here; see the "Directories" section to find the interfaces defined for specific services.

Specifying exponential backoff settings for HTTP request retries

By default, the API methods will retry HTTP requests using an exponential backoff algorithm, for failures that are considered potentially intermittent (such as 5xx HTTP status codes).

In order to adjust the default retry exponential backoff settings, you can do something like this:

import (
	"github.com/cenkalti/backoff/v3"
	"github.com/taskcluster/httpbackoff/v3"
	"github.com/taskcluster/taskcluster/v42/clients/client-go/tcqueue"
)
queue := tcqueue.NewFromEnv()
settings := &backoff.ExponentialBackOff{
	InitialInterval:     5 * time.Millisecond,
	RandomizationFactor: 0,
	Multiplier:          100,
	MaxInterval:         60 * time.Second,
	MaxElapsedTime:      100 * time.Millisecond,
	Clock:               backoff.SystemClock,
}
settings.Reset()
queue.HTTPBackoffClient = &httpbackoff.Client{
    BackOffSettings: settings,
}


### Generating Signed URLs

API methods which take credentials and have method GET can be invoked with a signed URL.
To generate such a URL, use the method with suffix `_SignedURL`, and pass as its final argument the duration for which the URL should be valid.
For example, to generate a URL for [Queue.GetArtifact](https://pkg.go.dev/github.com/taskcluster/taskcluster/v42/clients/client-go/tcqueue#Queue.GetArtifact_SignedURL):

```go
url := queue.GetArtifact_SignedURL(taskId, runId, "my/secret/artifact.txt", 5 * time.Minutes)

Generating Temporary Credentials

You can generate temporary credentials from permanent credentials using the Go client. This may be useful if you wish to issue credentials to a third party. See the manual for more information.

Create named credentials with Credentials.CreateNamedTemporaryCredentials, or unnamed credentials with Credentials.CreateTemporaryCredentials. Named credentials are preferred if you are not sure which type to use.

Example

package main

import (
	"fmt"
	"log"
	"os"
	"strconv"
	"time"

	tcclient "github.com/taskcluster/taskcluster/v42/clients/client-go"
	"github.com/taskcluster/taskcluster/v42/clients/client-go/tcqueue"
)

const (
	taskID  = "VESwp9JaRo-XkFN_bemBhw"
	runID   = 0
    rootURL = "https://tc.example.com"
)

// This simple demo lists the artifacts in run 0 of task
// VESwp9JaRo-XkFN_bemBhw. It creates permanent credentials from environment
// variables TASKCLUSTER_CLIENT_ID and TASKCLUSTER_ACCESS_TOKEN, and then
// creates temporary credentials, valid for 24 hours, from these permanent
// credentials. It queries the Queue using the temporary credentials, and with
// limited authorized scopes.
//
// Note, the queueClient.ListArtifacts(...) call doesn't require any scopes.
// The generation of temporary credentials, and limiting via authorized scopes
// is purely illustrative. The TASKCLUSTER_CLIENT_ID must satisfy
// auth:create-client:demo-client/taskcluster/clients/client-go, though.
func main() {
	permCreds := &tcclient.Credentials{
		ClientID:    os.Getenv("TASKCLUSTER_CLIENT_ID"),
		AccessToken: os.Getenv("TASKCLUSTER_ACCESS_TOKEN"),
	}
	tempCreds, err := permCreds.CreateNamedTemporaryCredentials(
		"demo-client/taskcluster/clients/client-go",
		time.Hour*24,
		"assume:legacy-permacred",
	)
	if err != nil {
		log.Fatalf("Could not create temporary credentials: %v", err)
	}
	tempCreds.AuthorizedScopes = []string{
		"queue:get-artifact:private/build/*",
	}
	queueClient, err := tcqueue.New(tempCreds, rootURL)
	if err != nil {
		// bug in code
		log.Fatalf("SERIOUS BUG! Could not create client from generated temporary credentials: %v", err)
	}
	listArtifactsResponse, err := queueClient.ListArtifacts(taskID, strconv.Itoa(runID), "", "")
	if err != nil {
		log.Fatalf("Could not call queue.listArtifacts endpoint: %v", err)
	}
	fmt.Printf("Task %v run %v artifacts:\n", taskID, runID)
	for _, artifact := range listArtifactsResponse.Artifacts {
		fmt.Printf("  * %v\n", artifact.Name)
	}
	fmt.Println("Done")
}

Handling Timestamps

Taskcluster uses RFC3339 timestamps, specifically with millisecond precision and a Z timestamp. To support serializing and deserializing this format exactly, use the tcclient.Time type instead of with the built-in time.Time type.

All timestamp arithmetic should be performed with the built-in time package.

Generating SlugIDs

To generate SlugIDs, such as for TaskIDs, use github.com/taskcluster/slugid-go.

Uploading and Downloading Objects

The Object Service provides APIs for reliable uploads and downloads of large objects (files). As with all taskcluster services, the tcobject package provides direct access to the underlying APIs, but in addition, also provides higher-level convenience methods that can be used to negotiate data transfers without the caller needing to be concerned with the underlying mechanics of the client/server communication.

Whether you choose to use the convenience methods, or call the underlying APIs directly, you will need a tcobject.Object with appropriate credentials for the operation.

To use the convenience upload methods:

object := tcobject.New()
buf := []byte{"Hello I am data to upload"}
err := object.UploadFromBuf(projectID, name, contentType, expires, buf)

or:

object := tcobject.New()
err := object.UploadFromFile(projectID, name, contentType, expires, filepath)

or:

object := tcobject.New()
err := object.UploadFromReadSeeker(projectID, name, contentType, contentLength, expires, readSeeker)

To use the convenience download methods:

object := tcobject.New()
data, contentType, contentLength, err := object.DownloadToBuf(name)

or:

object := tcobject.New()
contentType, contentLength, err := object.DownloadToFile(name, filepath)

or:

object := tcobject.New()
contentType, contentLength, err := object.DownloadToWriteSeeker(name, writeSeeker)

Note: the exponential backoff settings of the Object Service client (object.HTTPBackoffClient) are also used when uploading/downloading data to external URLs by these convenience methods.

Compatibility

This library is co-versioned with Taskcluster itself. That is, a client with version x.y.z contains API methods corresponding to Taskcluster version x.y.z. Taskcluster is careful to maintain API compatibility, and guarantees it within a major version. That means that any client with version x.* will work against any Taskcluster services at version x.*, and is very likely to work for many other major versions of the Taskcluster services. Any incompatibilities are noted in the Changelog.

Examples

To get you started quickly, some example programs are included that use both the HTTP APIs and the AMQP APIs:

This HTTP example program demonstrates the use of the tcauth package to query the expiry and expanded scopes of a given clientId.
This HTTP example program demonstrates the use of the tcauth package to update an existing clientId with a new description and expiry.
The AMQP example program demonstrates the use of the tcqueueevents package to listen in on Taskcluster tasks being defined and executed.
