Flow Control Options One of the benefits of writing your pipeline-as-code in Jenkins (versus using the tra ditional web forms) is that you have more options for controlling the flow through the pipeline. . Where Foo was a label for a text entry box in the form-based version of the plugin, there may now be a DSL call with Foo as a named parameter with a value passed in. In some cases where GUI elements were provided to interface with tooling, ways to send particular commands to the tooling through the Jenkins interface werent available. There is core support for pipelines both as jobs themselves and also separate from Jenkins, as Jenkinsfiles. . . stash and unstash In the Jenkins DSL, the stash and unstash functions allow for saving and retrieving (respectively) files between nodes and/or stages in a pipeline. Using a script block While Declarative Pipelines are continuing to evolve and add more functionality, there may still be instances where you need to do something in one that the declara tive style doesnt support or renders very difficult to implement. . . . Incorporating a significant amount of example code from our books into your product's documentation does require permission. On the downside, emailext is one of those steps that was targeted to do a lot by default based on global configuration and adding a post-build action to a Freestyle job. ), including its new features, the changes in the working environment, and an understanding of the new concepts that it is based on. . . Figure 4-3. . Blue Ocean adds a graphical representation for each stage of a pipeline showing indicators of success/failure and progress, and allowing point-and-click access to logs for each individual piece. The first executable statement in this stage is the one that is failing, so theres no further execution information to log. Use of the parameters directive is covered in detail with Declarative Pipelines in Chapter 7, but heres a simple example of the syntax (see parameters on page 234 for more details): pipeline { agent any parameters { string(name: 'USERID', defaultValue: '', description: 'Enter your userid') } stages { stage('Login') { steps { echo "Active user is now ${params.USERID}" } } 76 | Chapter 3: Pipeline Execution Flow } } Figure 3-7. .

Learn more Kindle $13.20 - $36.79 Paperback $29.40 - $38.54 Other Sellers from Buy used:: $29.40 These types of jobs are identified by having Jenkinsfiles and are triggered otherwise, such as by a webhook that notifies Jenkins when a change is made. . Extending Your PipelineChapter 7. In this case, we are simply using the always clause for a generic dem onstration. . The Jenkins DSL, like many others, is written using the Groovy programming lan guage. Because of this, it is advisable to try to limit accessing input to a small section of your code if you have to use a script block. As such, its worth spending a few minutes to discuss the reasons for the change. These pipelines will produce an email like the following if there is a failure: ---------------------------- Original Message ---------------------------Subject: Status of pipeline: pipeline2 #1 From: [emailprotected] Date: Tue, August 15, 2017 9:33 pm To: [emailprotected] -------------------------------------------------------------------------http://jenkins1.demo.org/job/pipeline2/1/ has result FAILURE If there is a successful build, this will look the same except FAILURE will be replaced with SUCCESS.

Where I need to explain larger constructs, Ill include examples of both, where it would make a difference. Heres an example of the structure with try-catch-finally: def err = null try { // pipeline code node ('node-name') { stage ('first stage') { } // end of last stage } } catch (err) { currentBuild.result = "FAILURE" } finally { (currentBuild.result != "ABORTED"){ // Send email notifications for builds that failed // or are unstable } } Notice that we are setting the value of currentBuild.result if there is an error, to ensure the build status is consistent with what we expect from Jenkins. . With this book, youre on your way to leveraging the features of Jenkins 2 to design, implement, and execute your pipelines with a level of flexibility, control, and ease of maintenance that hasnt been possible with Jenkins before. . . Pipeline tab with a simple script example The code for our pipeline is entered through the built-in Jenkins editor. }); Given this step, when you run the job, a POST to this URL could be used to respond. In this chapter, well explore at a high level what makes Jenkins 2 different and how that will fit in with what youre accustomed to. The H symbol can also have a range attached to it to specify limits on the interval it can pick. If the timeout is hit, then the step will throw an exception. An additional area thats worth mentioning is plugin compatibility. You may be able to achieve a similar effect by using the throttle() step from the Throttle Concurrent Builds plugin. . Login to YUMPU News Login to YUMPU Publishing xvii Its an ideal book for those who are new to CI/CD, as well as those who have been using Jenkins for many years. . For passwords, the text the user enters is hidden while they type it. Color processing legend Color Blue stripes White Rose stripes Green Rose Meaning Processing in progress Stage has not been run yet Stage failed Stage succeeded Stage succeeded but some other stage failed downstream Color Changes When Processing Even though a tile may be green at one point, it can still change to the rose color later if a downstream stage fails. Anne-Marie, you have been my greatest support and source of strength and encouragement, as you are in everything.

It is available on the Jenkins wiki. For example: emailext body: 'body goes here', recipientProviders: [[$class: 'CulpritsRecipientProvider'], [$class: 'DevelopersRecipientProvider'], [$class: 'RequesterRecipientProvider'], [$class: 'FailingTestSuspectsRecipientProvider'], [$class: 'FirstFailingBuildSuspectsRecipientProvider'], [$class: 'UpstreamComitterRecipientProvider']], subject: 'subject goes here' Triggers. But it may have use in other types of applications for Jenkins, such as starting jobs at particular intervals to avoid collisions for resources. . . This also means the content of the Snippet Generator on any particular Jenkins instance is a function of what plugins are installed on that instance. ', submitterParameter: 'approver' echo "Answered by ${resp}" If you have any other parameters, then you must supply the submitterParameters name to access it: def resp = input id: 'ctns-prompt', message: 'Continue to the next stage? An example of using this is shown here: node ('node-name') { catchError { stage ('first stage') { } // end of last stage } // step to send email notifications } This is essentially equivalent to the following code: node ('node-name') { try { stage ('first stage') { } // end of last stage } catch (err) { echo "Caught: ${err}" currentBuild.result = 'FAILURE' } // step to send email notifications } The advantages are the simpler syntax and the build result automatically being marked as failed if an exception occurs. . We can then accept the defaults for those parameters or set them to specific values as needed. . A tag already exists with the provided branch name. . . Code block for source pull We know we want to use Git, but were not sure of the syntax, so we click the Pipeline Syntax link at the bottom of the Pipeline tabs window, as shown in Figure 2-12. All Rights Reserved. Here, 0 and 7 both represent Sunday. . The email-ext plugin requires some global configuration before being used in Pipeline jobs. In those instances, you may have to resort to using Groovy constructs that can mimic the pro cessing that Jenkins would do. . This book is intended to help you find answers on how to use this powerful technol ogy. A new build record of that run is kept, but the original code remains unchanged.

In addition to repeatable processing that is triggered by some event, we also rely on being automatically noti fied when processes have completed, and of their overall status. . . . . nav: true, Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Also, we are setting the returnStatus parameter to true for the shell call, so that we get the return code back from the operation to check for suc cess: timeout(time:15, unit:'SECONDS') { waitUntil { 84 | Chapter 3: Pipeline Execution Flow def ret = sh returnStatus: true, script: 'test -e /home/jenkins2/marker.txt' return (ret == 0) } } As another example, suppose we are waiting for a Docker container to start up so that we can get some data via a REST API call as part of our pipeline testing. The step accepts the same kinds of parameters as a regular Jenkins job for a Scripted Pipeline. . . . You can put the return value into an environment variable and then access the environment variable wherever you need the value. . Now, Jenkins 2 takes this open-source automation server to a new level. The first one in the list will be the default. items: 4 . An example follows. (Note that this properties section will be merged with any properties defined in the web inter face, with the web properties taking precedence.) .

Integrating Containers. The syntax here is fairly simple. . Well also look at how to access logs from a run. . Feel free to refer back to it as many times as needed as you begin using Jenkins 2 and creating your pipelines-as-code. It is technically a step, meaning something that can be used to cause an action to occur in a pipeline. Figure 3-16. The loop then iterates, setting the key to "Step" and the value for each to a node block that echos start, sleeps, and then echos done. Well also look at the constructs available to map the Conditional BuildStep functionality into pipelines. . Wrapping those steps in different nodes allows for the best parallelism. What Is Jenkins 2? But I suggest at least scanning those sections that look familiar. As with the pre vious example, this code could be directly copied and pasted into a script to use. For the Repository URL subparameter, Jenkins expects you to specify the URL of the Subversion repository that contains the tags you want to display. . . Excluded Recipients As the name implies, this can exclude (filter out) any email addresses from the list generated by other functionality in this plugin. . Declarative Pipelines. Also, we dont Post-Processing | 101 send mail if the build was aborted. This model is what we now refer to as Scripted Pipelines. In this section, well cover some basic terms and the structure and functionality of a Jenkins DSL pipeline. The main way people find out about useful books is by word of mouth and online reviews. . . MONTH Desired month of the year (112). . Overriding default values for the git step Any time multiple parameters are specified, they must all be named. All of this leads to easier maintainability and testing as well as more resiliency. . 59 Triggering Jobs To specify triggering events for pipeline code, there are three different approaches: If working in the Jenkins application itself in a pipeline job, the trigger(s) can be specified in the traditional way within the projects General configuration section in the web interface. The five fields are: MINUTES Desired minutes value within the hour (059). . Well talk more about declarative syntax and pipelines in Chapter 7, which is devoted to helping you understand that model. | 3 Figure 1-1. Conversions. . Created. } Thanks also to Nan Barber for her early work on the book editing. . . . Sams Teach Yourself JavaScript in 24 Hours, 7th Edition, The Busy Coders Guide to Android Development Final Version. . Dealing with Concurrency | 85 Locking Resources with the lock Step If you have the Lockable Resources plugin installed, there is a DSL lock step available to restrict multiple builds from trying to use the same resource at the same time. Take OReilly with you and learn anywhere, anytime on your phone and tablet. The last bullet is a recommended practice. Author Brent Laster shows you how Jenkins 2 is significantly different from the more traditional, web-only versions of this popular open source automation platform. This greatly simplifies trying to figure out how to use a particular step. So, in this case, you could add the label Linux to all of the nodes and an additional label to indicate where each is locatedi.e., east or west. Additionally, many plugins and steps produce useful reports as part of their processing. . Login to YUMPU News Login to YUMPU Publishing . OK button caption (ok) A different label you can use instead of Proceed. For example: input message: '', ok: 'Yes' Allowed submitter (submitter) A comma-separated list of user IDs or group names for people authorized to respond. Regardless, it is a required field. . If that time passes, Jenkins will throw an exception causing the pipeline to abort. As a quick example, consider a Declarative Pipeline where we want to use a certain agent to do the build on, no matter how many instances of the pipeline we are run ning. Are you sure you want to create this branch? The following example code shows how to define the input statement along with some print statements that show different ways to access the individual return values (dont forget that you can use the Snippet Generator for generating the input state ment as well): def loginInfo = input message: 'Login', parameters: [string(defaultValue: '', description: 'Enter Userid:', name: 'userid'), password(defaultValue: '', description: 'Enter Password:', name: 'passwd')] echo "Username = " + loginInfo['userid'] echo "Password = ${loginInfo['passwd']}" echo loginInfo.userid + " " + loginInfo.passwd Parameters and Declarative Pipelines Since creating new local variables to hold the return values from input statements doesnt fit the declarative model, you may be wondering how we can use the input statement in Declarative Pipelines. Once nodes are available to execute code, we can start focusing on creating pipelines. . . The URL format would be: http://[jenkins-base-url]/job/[job_name]/[build_id]/input/Ctns-prompt/ proceedEmpty to tell Jenkins to proceed without any input, or: http://[jenkins-base-url]/job/[job_name]/[build_id]/input/Ctns-prompt/ abort to tell Jenkins to abort. . . . But perhaps the most useful option it provides is a web form with areas to enter values for the parameters you want to use. . In that case, the Source stage would have been striped and the Build stage would have been white. Rather, it presents the interface to select an existing credential or add a new one. If youve done any work with Jenkins before, youre probably already familiar with most of these. Your email address will not be published. Using the global tool Gradle version in a Freestyle project stage('Compile') { // Compile and do unit testing // Run gradle to execute compile sh "${tool 'gradle3.2'}/bin/gradle clean build" } Declarative Pipelines also have a tool directive that allows for the same functionality in that type of pipeline. True PDF; Table of contents : Chapter 1. In a Scripted Pipeline, this usually entails using a try-catch-finally construct if you want to always do postprocessing (as described in Chapter 3). . Download Jenkins 2: Up and Running: Evolve Your Deployment Pipeline for Next Generation Automation PDF . . . The context in Jenkins is creating pipe lines. . . loop: true, . Now, Jenkins 2 takes this open-source automation server to a new level. . . . . . Jenkins 2: Up and Running, by Brent Laster. We are limited to the DSL steps plus whatever can be done with Groovy coding. There was very little imposed structure, and the program flow was managed by Groovy constructs. DevOps Movement The ideas behind continuous integration, continuous delivery, and continuous deployment have been around for a number of years. . . Including logs. So, to always send an email after a build, we need to resort to coding as shown here: node { try { // do some work } catch(e) { currentBuild.result = "FAILED" throw e } finally { mail to:"[emailprotected]", subject:"STATUS FOR PROJECT: ${currentBuild.fullDisplayName}", body: "RESULT: ${currentBuild.result}" } } Assuming we have our email setup already configured globally in Jenkins, we can use the DSL mail statement to send an email. . Heres a simple example: input 'Continue to next stage?' }); Can also be empty, as indicated by input ''. . . . You can choose the ending status you want the builds of the other projects to have (stable, unstable, or failed). . His input has been invaluable and I appreciate the time and openness that he has given to this project. . The syntax is: def selectedFile = input message: '', parameters: [file(description: 'Choose file to upload', name: 'local')] Note that the item returned for this type of parameter is a hudson.FilePath object. . If you only specify a time value, it will be assumed to be in minutes. . You can omit supplying a label here, but if you omit a label, then you need to be aware of how this will be handled: If master has been configured as the default node for execution, Jenkins will run the job on master. . This is done because of some of the nice features that Groovy provides that make creating DSLs easier than in other languages. Dealing with Concurrency | 89 Traditional parallel syntax The traditional parallel pipeline step takes a map as an argument. Obviously these arent exact classifications, but they may serve you as a handy memory device when you are first getting familiar with this arrangement. . 104 | Chapter 3: Pipeline Execution Flow CHAPTER 4 Notifications and Reports One of the core uses of Jenkins is implementing automation. There are other ways to instantiate a set of choices, but this is the simplest. You can instead use multiple parameters in an input statement and set an environment variable with the results. . This was used to allow advanced scripting operations and to provide access/functionality not available through the web interface. . Parallel run with stash and unstash used to share files across nodes 94 | Chapter 3: Pipeline Execution Flow Parallel Test Executor Plugin A separate plugin is available that can help with parallelizing sets of tests if they are taking up significant time in your pipeline. When Jenkins is notified, it detects the Jenkinsfile as a marker in the repository and executes the commands in the Jenkinsfile to run the pipeline. . In general, any kind of server setup or similar task is done on the Configure System screen. Many of the options fall into the 105 area of instant messaging, and even allow the user to do things like specify coloring for messages. . . . This step can also optionally take parameters to gather additional information. . . Controlling Concurrent Builds with Milestones One of the scenarios that you might have to deal with at some point in Jenkins is builds of the same pipeline running concurrently that can have contention for resour ces. However, you can also take the DSL code and save it externally as a text file with your source code. Once thats done, you could specify which nodes to use by using combinations of operands and labels. } Simply hover over the tile representing the build and stage that youre interested in and click the Logs button in the block that appears, and youll get a pop-up showing the stage logs. In a Declara tive Pipeline, specifying a particular agent to use allocates a node. let src = response.html; .

If youre interested in these, there are a number of recipes available on the web. The following code excerpt shows a simple example of specifying a node step: // Scripted Pipeline node('worker') { stage('Source') { // Get code // Get code from our Git repository agent, on the other hand, is a directive in a Declarative Pipeline. The new syntax more closely matches the structured form of Declarative Pipelines. Save my name, email, and website in this browser for the next time I comment. Once you have that, its a simple cut and paste to get it into your program. Since the first echo is in the script block where the variable resp is also defined, it will print out the response that is entered for that parameter as expected. . The Project subparameter is the job that you want to allow the user to select a run from. To use this setting in the pipeline step, you can simply enable the options shown here: attachLog: true, compressLog:true Ultimately, the plugin provides a mixed bag for Pipeline developers. . . See Chapter 16 for some suggestions on how to work around this type of issue. Description. . . A node can have zero or more executors. Nondeclarative Code and Blue Ocean If you plan to use your pipeline with Blue Ocean, be aware that the built-in editor is designed to work primarily with declarative syn tax. Figure 2-7 shows an example of the tab with a simple pipeline script typed in. . .

Ive worried about this at some level, but decided that there were two ways to go when writing it: I could either limit the content to only what was needed to do a basic tutorial, or I could spend some time explaining concepts, creating code examples, and diving into what termi nology, functions, and programming with pipelines-as-code really mean. User Input | 67 URLs and Crumbs If your Jenkins is configured to prevent Cross-Site Request Forgery (CSRF) exploits via the Security settings (strongly recommended), then any URL used to POST will need to also include a CSRF pro tection token. . The subparameters avail able include Name, Project, Description, and Filter. . (For examples of how to send mail and other noti fications, see Chapter 4.) Figure 1-6 shows a traditional Freestyle projects post-build configuration for a typical operation, sending email notifications. When run, due to the individual stage definitions, it will also produce stage output for each substage (Figure 3-16) as opposed to the single set of output of the traditional parallel syntax (Figure 3-17). Global configuration. . . In fact, the pipeline DSL has special constructs for doing thisa traditional one that fits both Scripted and Declarative Pipelines, and a newer one just for Declarative Pipelines. . Dive in for free with a 10-day trial of the OReilly learning platformthen explore all the other resources our members count on to build skills and solve problems every day. Workflow changes (such as reordering steps in a job or changing the order in which jobs executed) could require multiple interactions of clicking and dragging and typing, as opposed to sim pler updates available in a text editor interface. To be clear, if concurrent builds reach the milestone in the order they were started, they can all pass the milestone. You can have all of your code in the Jenkinsfile, or you can call out/pull in other external code via shared libraries. Figure 3-15. . 112 | Chapter 4: Notifications and Reports As well as providing more options for the content of emails, the extended email func tionality also provides more options for choosing the types of recipients to send emails to.
