Jenkins pipeline examples

Jenkins Pipeline or simply "Pipeline" is a suite of plugins which supports implementing and integrating continuous delivery pipelines into Jenkins. A continuous delivery pipeline is an automated expression of your process for getting software from version control right through to your users and customers.

Jenkins Pipeline provides an extensible set of tools for modeling simple-to-complex delivery pipelines "as code". For more information about Pipeline and what a Jenkinsfile is, refer to the respective Pipeline and Using a Jenkinsfile sections of the User Handbook. Copy one of the examples below into your repository and name it Jenkinsfile.

Click the New Item menu within Jenkins. Provide a name for your new item e. My Pipeline and select Multibranch Pipeline. Click the Add Source button, choose the type of repository you want to use and fill in the details. You may need to modify one of the example Jenkinsfile 's to make it run with your project. Try modifying the sh command to run the same command you would run on your local machine.

After you have setup your Pipeline, Jenkins will automatically detect any new Branches or Pull Requests that are created in your repository and start running Pipelines for them. Please submit your feedback about this page through this quick form.

A continuous delivery CD pipeline is an automated expression of your process for getting software from version control right through to your users and customers. Every change to your software committed in source control goes through a complex process on its way to being released.

This process involves building the software in a reliable and repeatable manner, as well as progressing the built software called a "build" through multiple stages of testing and deployment.

Pipeline provides an extensible set of tools for modeling simple-to-complex delivery pipelines "as code" via the Pipeline domain-specific language DSL syntax. Creating a Jenkinsfile and committing it to source control provides a number of immediate benefits:.

Single source of truth [ 3 ] for the Pipeline, which can be viewed and edited by multiple members of the project. While the syntax for defining a Pipeline, either in the web UI or with a Jenkinsfile is the same, it is generally considered best practice to define the Pipeline in a Jenkinsfile and check that in to source control.

Declarative and Scripted Pipelines are constructed fundamentally differently. Declarative Pipeline is a more recent feature of Jenkins Pipeline which:. Many of the individual syntactical components or "steps" written into a Jenkinsfilehowever, are common to both Declarative and Scripted Pipeline. Read more about how these two types of syntax differ in Pipeline concepts and Pipeline syntax overview below.

Similarity measures

Jenkins is, fundamentally, an automation engine which supports a number of automation patterns. Pipeline adds a powerful set of automation tools onto Jenkins, supporting use cases that span from simple continuous integration to comprehensive CD pipelines. By modeling a series of related tasks, users can take advantage of the many features of Pipeline:. Code : Pipelines are implemented in code and typically checked into source control, giving teams the ability to edit, review, and iterate upon their delivery pipeline.

Durable : Pipelines can survive both planned and unplanned restarts of the Jenkins master. Pausable : Pipelines can optionally stop and wait for human input or approval before continuing the Pipeline run.

Extensible : The Pipeline plugin supports custom extensions to its DSL [ 1 ] and multiple options for integration with other plugins. While Jenkins has always allowed rudimentary forms of chaining Freestyle Jobs together to perform sequential tasks, [ 4 ] Pipeline makes this concept a first-class citizen in Jenkins. Building on the core Jenkins value of extensibility, Pipeline is also extensible both by users with Pipeline Shared Libraries and by plugin developers. The following concepts are key aspects of Jenkins Pipeline, which tie in closely to Pipeline syntax see the overview below.

A Pipeline is a user-defined model of a CD pipeline.This section builds on the information introduced in Getting started with Pipeline and should be treated solely as a reference. For more information on how to use Pipeline syntax in practical examples, refer to the Using a Jenkinsfile section of this chapter.

As of version 2. For the pros and cons of each, see the Syntax Comparison. As discussed at the start of this chapterthe most fundamental part of a Pipeline is the "step". Basically, steps tell Jenkins what to do and serve as the basic building block for both Declarative and Scripted Pipeline syntax. For an overview of available steps, please refer to the Pipeline Steps reference which contains a comprehensive list of steps built into Pipeline as well as steps provided by plugins.

Declarative Pipeline is a relatively recent addition to Jenkins Pipeline [ 1 ] which presents a more simplified and opinionated syntax on top of the Pipeline sub-systems. All valid Declarative Pipelines must be enclosed within a pipeline block, for example:. Blocks must only consist of SectionsDirectivesStepsor assignment statements. A property reference statement is treated as a no-argument method invocation. So, for example, input is treated as input.

You can use the Declarative Directive Generator to help you get started with configuring the directives and sections in your Declarative Pipeline. Sections in Declarative Pipeline typically contain one or more Directives or Steps. The agent section specifies where the entire Pipeline, or a specific stage, will execute in the Jenkins environment depending on where the agent section is placed. The section must be defined at the top-level inside the pipeline block, but stage-level usage is optional.

There are some nuances when adding an agent to the top level or a stage level, and this when the options directive is applied. In agents declared at the outermost level of the Pipeline, the options are invoked after entering the agent. As an example, when using timeout it will be only applied to the execution within the agent. In agents declared within a stage, the options are invoked before entering the agent and before checking any when conditions.

In this case, when using timeoutit is applied before the agent is allocated. The timeout will include the agent provisioning time. Because the timeout includes the agent provisioning time, the Pipeline may fail in cases where agent allocation is delayed.

When using timeoutit will applied before the agent therefore the timeout will account for the provisioning time.

Pipeline Syntax

This may cause the pipeline to timeout if it takes too long to allocate an agent. In order to support the wide variety of use-cases Pipeline authors may have, the agent section supports a few different types of parameters.

These parameters can be applied at the top-level of the pipeline block, or within each stage directive. When applied at the top-level of the pipeline block no global agent will be allocated for the entire Pipeline run and each stage section will need to contain its own agent section.

For example: agent none. Execute the Pipeline, or stage, on an agent available in the Jenkins environment with the provided label. Label conditions can also be used. Execute the Pipeline, or stage, with the given container which will be dynamically provisioned on a node pre-configured to accept Docker-based Pipelines, or on a node matching the optionally defined label parameter.

The parameter registryCredentialsId could be used alone for private repositories within the docker hub. For example:. Execute the Pipeline, or stage, with a container built from a Dockerfile contained in the source repository.

If your Dockerfile has another name, you can specify the file name with the filename option.The following examples are sourced from the the pipeline-examples repository on GitHub and contributed to by various members of the Jenkins project. This shows usage of a simple build wrapper, specifically the AnsiColor plugin, which adds ANSI coloring to the console output.

This is a simple demonstration of how to archive the build output artifacts in workspace for later use. This is a simple demonstration of how to download dependencies, upload artifacts and publish build info to Artifactory. Read the full documentation here. This is a simple demonstration of how to run a Gradle build, that resolves dependencies, upload artifacts and publish build info to Artifactory.

This is a simple demonstration of how to run a Maven build, that resolves dependencies, upload artifacts and publish build info to Artifactory.

Plugin works in such a way as to make the configuration available for the entire duration of the build across all the build agents that are used to execute the build. Shows how to allocate the same workspace on multiple nodes using the External Workspace Manager Plugin. Before using this script, you must configure several prerequisites. A starting guide may be found in the prerequisites section, from the plugin's documentation. Additional examples can be found on the plugin's documentation pagealong with all the available features.

The git plugin exposes some environment variables to a freestyle job that are not currently exposed to a Pipeline job. Here's how to recover that ability using a git command and Pipeline's sh step. The IRC protocol is simple enough that you can use a pipeline shell step and nc to send a message to an irc room. You will need to customize the script to use the actual room, server, and authentication details.

A very simple example demonstrating how the load method allows you to read in Groovy files from disk or from the web and then call the code in them. An example showing how to build a standard maven project with specific versions for Maven and the JDK. An example showing how to search for a list of existing jobs and triggering all of them in parallel.

Calling other jobs is not the most idiomatic way to use the Worflow DSL, however, the chance of re-using existing jobs is always welcome under certain circumstances. An example showing how to take a list of objects and transform it into a map of steps to be run with the parallel command. This is a simple example showing how to succinctly parallel the same build across multiple Jenkins nodes.

This is useful for e. This demonstrates how to push a tag or branch, etc to a remote Git repository from within a Pipeline job.

The authentication step may vary between projects. If you inject a credential associated with your Git repo, use the Snippet Generator to select the plain Git option and it will return a snippet with this gem:. Using a combination of groovy and curl from shell, send a message to slack for notifications. However, we can use groovy's built in json handling to build up the request and ship it to a command line curl easily enough.

This will require that you configure a webhook integration in slack not the Jenkins specific configuration. This shows usage of a simple build wrapper, specifically the Timestamper plugin, which adds timestamps to the console output.

A pipeline has an extensible automation server for creating simple or complex delivery pipelines "as code," via pipeline DSL Domain-specific Language.

What is Continuous Delivery Pipelines? How it Works? In a Jenkins pipeline, every job or event has some sort of dependency on at least one or more events. The picture above represents a continuous delivery pipeline in Jenkins. It contains a group of states called build, deploy, test and release.

These events are interlinked with each other. Every state has its events, which work in a sequence called a continuous delivery pipeline. A continuous delivery pipeline is an automated expression to display your process for getting software for version control.

Creating your first Pipeline

Thus, every change made in your software goes through a number of complex processes on its way to being released. It also involves developing the software in a reliable and repeatable manner, and progression of the built software through multiple stages of testing and deployment.

In this tutorial, you will learn What is Jenkins Pipeline? What is a JenkinsFile? Why Use Jenkin's Pipeline? Jenkins pipelines can be defined using a text file called JenkinsFile.

You can implement pipeline as code using JenkinsFile, and this can be defined by using a domain specific language DSL. With JenkinsFile, you can write the steps needed for running a Jenkins pipeline. The benefits of using J enkinsFile are : You can create pipelines automatically for all branches and execute pull requests with just one JenkinsFile. You can review your code on the pipeline You can audit your Jenkins pipeline This is the singular source for your pipeline and can be modified by multiple users.

Declarative versus Scripted pipeline syntax: There are two types of syntax used for defining your JenkinsFile.The default interaction model with Jenkins, historically, has been very web UI driven, requiring users to manually create jobs, then manually fill in the details through a web browser. The Pipeline plugin was inspired by the Build Flow plugin but aims to improve upon some concepts explored by Build Flow with features like:.

In an adjacent space is the Job DSL plugin which is worth mentioning as well. The Pipeline plugin has a fairly comprehensive tutorial checked into its source tree too.

The presentations below were given by Jesse Glickauthor of the Pipeline Plugin. Azure Key Vault is a product for securely managing keys, secrets and certificates. These changes were released in v1. We know that for many of our customers Jenkins is incredibly important and its integration with Bitbucket Server is a key part of their development workflow. We began building our own integration, and The Problem I was often struggling with the same issues when working with Jenkins: Code duplication and security - Jenkinsfiles in every repository.

A branch is API keys and secrets are difficult to handle safely, and probably something you avoid thinking about. Table of Contents Matrix building with scripted pipeline Screenshot of matrix pipeline Adding static choices Adding dynamic choices Full pipeline example with dynamic choices Background: How does it work?

Exposing a shared library pipeline step Summary With the recent announcement about matrix building you can perform Matrix builds with declarative pipeline. The examples I often find myself needing to run the same actions on a bunch of different configurations. Up to now, that meant I had to make multiple copies of the same stages in my pipelines.Jenkins Pipeline is the workflow that implements Continuous Delivery pipeline with the Jenkins features, tools and plugins.

There are two different ways to create Jenkins pipeline. One is Declarative Pipeline, and another is Scripted Pipeline.

In this article, we will see about how to create Jenkins Declarative pipeline. This tutorial will give you insight on the structure and directives of declarative pipeline and syntax. Basically, this pipeline label opens the block where following directives and blocks are present. Let us see all these directives and blocks one by one in this Jenkins Declarative Pipeline Tutorial.

Pipeline is a block where all other blocks and directives are declared. This is the starting of the Declarative pipeline. So, Pipeline label will be declared as follows. Jenkins is popular for one of its best feature called distributed build process to the agent nodes.

Jenkins build pipeline plugin ensures the same feature present in the pipeline that are created in the Declarative method. Normally, agent will be declared at the top-level as a global agent declaration. So, Agent label is ideally mentioned with following parameters. Stages is the section which contain one or more stage tag. So, In this section we can write the part of continuous delivery process. This is the section which contain steps section or agent section which is isolated for the particular stage and other directives.

A stage can have multiple commands to run for completing the continuous delivery process. Environment is the directive which contains the Key-value pairs of environment variable that should be available for the steps that are going to be executed in the stages. Ideally, Environment directive supports special helper method called credentials type which is very helpful for dynamically passing the credentials into the steps.

So, Following are the types of credentials that can be passed in to the environments. Input Directive is declared inside stage and it will help us getting input by prompting users. Basically, The stage section will wait until any Input is submitted.

So, Following are the configuration options. Options derivatives will provide options for configuring the pipeline with in the pipeline. So, Let us discuss the options one by one.

This can be either for from the user input or from the Built-in conditions. Parallel block will allow us to run the stages concurrently. Idealy, Stages that are declared inside the Parallel derivative will run concurrently at the same time. Parameter Directive will provide the trigger parameters to the pipeline. Following are the available Parameters.

This will execute some commands after the stage or steps as per the condition. Following are some example of the conditions. Triggers are the typical Build triggers. This can be happening in any form like cronpollscm, Upstream. Hope this Jenkins Declarative Pipeline Tutorial helps you understand the basic structure of the Declarative pipeline.
