Jenkins API Client for Go

About

Jenkins is the most popular Open Source Continuous Integration system. This Library will help you interact with Jenkins in a more developer-friendly way.

These are some of the features that are currently implemented:

• Get information on test-results of completed/failed build
• Ability to query Nodes, and manipulate them. Start, Stop, set Offline.
• Ability to query Jobs, and manipulate them.
• Get Plugins, Builds, Artifacts, Fingerprints
• Validate Fingerprints of Artifacts
• Create and Delete Users
• Get Current Queue, Cancel Tasks
• Create and Revoke API Tokens
• etc. For all methods go to GoDoc Reference.

Installation

go get github.com/bndr/gojenkins

CLI

For users that would like CLI based on gojenkins, follow the steps below:

$ cd cli/jenkinsctl $ make

Usage

import (
  "github.com/bndr/gojenkins"
  "context"
  "time"
  "fmt"
)

ctx := context.Background()
jenkins := gojenkins.CreateJenkins(nil, "http://localhost:8080/", "admin", "admin")
// Provide CA certificate if server is using self-signed certificate
// caCert, _ := ioutil.ReadFile("/tmp/ca.crt")
// jenkins.Requester.CACert = caCert
_, err := jenkins.Init(ctx)


if err != nil {
  panic("Something Went Wrong")
}

job, err := jenkins.GetJob(ctx, "#jobname")
if err != nil {
  panic(err)
}
queueid, err := job.InvokeSimple(ctx, params) // or  jenkins.BuildJob(ctx, "#jobname", params)
if err != nil {
  panic(err)
}
build, err := jenkins.GetBuildFromQueueID(ctx, job, queueid)
if err != nil {
  panic(err)
}

// Wait for build to finish
for build.IsRunning(ctx) {
  time.Sleep(5000 * time.Millisecond)
  build.Poll(ctx)
}

fmt.Printf("build number %d with result: %v\n", build.GetBuildNumber(), build.GetResult())

API Reference: https://godoc.org/github.com/bndr/gojenkins

Examples

For all of the examples below first create a jenkins object

import "github.com/bndr/gojenkins"

jenkins, _ := gojenkins.CreateJenkins(nil, "http://localhost:8080/", "admin", "admin").Init(ctx)

or if you don't need authentication:

jenkins, _ := gojenkins.CreateJenkins(nil, "http://localhost:8080/").Init(ctx)

you can also specify your own http.Client (for instance, providing your own SSL configurations):

client := &http.Client{ ... }
jenkins, := gojenkins.CreateJenkins(client, "http://localhost:8080/").Init(ctx)

By default, gojenkins will use the http.DefaultClient if none is passed into the CreateJenkins() function.

Check Status of all nodes

nodes := jenkins.GetAllNodes(ctx)

for _, node := range nodes {

  // Fetch Node Data
  node.Poll(ctx)
    if node.IsOnline(ctx) {
        fmt.Println("Node is Online")
    }
}

Get all Builds for specific Job, and check their status

jobName := "someJob"
builds, err := jenkins.GetAllBuildIds(ctx, jobName)

if err != nil {
  panic(err)
}

for _, build := range builds {
  buildId := build.Number
  data, err := jenkins.GetBuild(ctx, jobName, buildId)

  if err != nil {
    panic(err)
  }

    if "SUCCESS" == data.GetResult(ctx) {
        fmt.Println("This build succeeded")
    }
}

// Get Last Successful/Failed/Stable Build for a Job
job, err := jenkins.GetJob(ctx, "someJob")

if err != nil {
  panic(err)
}

job.GetLastSuccessfulBuild(ctx)
job.GetLastStableBuild(ctx)

Get Current Tasks in Queue, and the reason why they're in the queue

tasks := jenkins.GetQueue(ctx)

for _, task := range tasks {
    fmt.Println(task.GetWhy(ctx))
}

Create View and add Jobs to it

view, err := jenkins.CreateView(ctx, "test_view", gojenkins.LIST_VIEW)

if err != nil {
  panic(err)
}

status, err := view.AddJob(ctx, "jobName")

if status != nil {
  fmt.Println("Job has been added to view")
}

Create nested Folders and create Jobs in them

// Create parent folder
pFolder, err := jenkins.CreateFolder(ctx, "parentFolder")
if err != nil {
  panic(err)
}

// Create child folder in parent folder
cFolder, err := jenkins.CreateFolder(ctx, "childFolder", pFolder.GetName())
if err != nil {
  panic(err)
}

// Create job in child folder
configString := `<?xml version='1.0' encoding='UTF-8'?>
<project>
  <actions/>
  <description></description>
  <keepDependencies>false</keepDependencies>
  <properties/>
  <scm class="hudson.scm.NullSCM"/>
  <canRoam>true</canRoam>
  <disabled>false</disabled>
  <blockBuildWhenDownstreamBuilding>false</blockBuildWhenDownstreamBuilding>
  <blockBuildWhenUpstreamBuilding>false</blockBuildWhenUpstreamBuilding>
  <triggers class="vector"/>
  <concurrentBuild>false</concurrentBuild>
  <builders/>
  <publishers/>
  <buildWrappers/>
</project>`

job, err := jenkins.CreateJobInFolder(ctx, configString, "jobInFolder", pFolder.GetName(), cFolder.GetName())
if err != nil {
  panic(err)
}

if job != nil {
    fmt.Println("Job has been created in child folder")
}

Get All Artifacts for a Build and Save them to a folder

job, _ := jenkins.GetJob(ctx, "job")
build, _ := job.GetBuild(ctx, 1)
artifacts := build.GetArtifacts(ctx)

for _, a := range artifacts {
    a.SaveToDir("/tmp")
}

To always get fresh data use the .Poll() method

job, _ := jenkins.GetJob(ctx, "job")
job.Poll()

build, _ := job.getBuild(ctx, 1)
build.Poll()

Create and Delete Users

// Create user
user, err := jenkins.CreateUser(ctx, "username", "password", "fullname", "user@email.com")
if err != nil {
  log.Fatal(err)
}
// Delete User
err = user.Delete()
if err != nil {
  log.Fatal(err)
}
// Delete user not created by gojenkins
err = jenkins.DeleteUser("username")

Create and Revoke API Tokens

// Create a token for admin user
token, err := jenkins.GenerateAPIToken(ctx, "TestToken")
if err != nil {
  log.Fatal(err)
}

// Set Jenkins client to use new API token
jenkins.Requester.BasicAuth.Password = token.Value

// Revoke token that was just created
token.Revoke()

// Revoke all tokens for admin user
err = jenkins.RevokeAllAPITokens(ctx)
if err != nil {
  log.Fatal(err)
}
