Select a Jenkins master from the Master drop-down menu, then select a job fromthe Job drop-down.
Add a property file, if desired. See thepropertyfilessection of thePipeline Expression Guide for more information about how to specify and useproperty files.
Build Artifacts
Jenkins has the ability to save files from a build as a build artifacts. These objects could be compiled binaries or kubernetes manifests or any other artifact created as part of the build process.
Best practice dictates that these artifacts should be uploaded to a dedicated artifact repository such as GCR, DockerHub, Artifactory, Maven etc, however sometimes it’s easier to store the artifact as part of the build output.
Here is an example of a Jenkins pipeline that stores artifacts
stages{stage('Generate Kubernetes Manifests'){steps{sh''' npm install npm run import npm run build echo "BUILD=${BUILD_NUMBER}" > build.properties '''}}}post{always{archiveArtifactsartifacts:'dist/*.yaml',fingerprint:truearchiveArtifactsartifacts:'build.properties',fingerprint:true}}
This job will generate the following artifacts
The line echo "BUILD=${BUILD_NUMBER}" > build.properties adds a build number field to the build.properties which can be used later to generate the URL used to download the artifact using HTTP.
The build.properties artifact should be added to the Jenkins trigger like this
Finally to add the Jenkins build artifact as a Spinnaker artifact, do the following
Create a HTTP File artifact account for Jenkins using the Jenkins base URL and credentials that has permissions to access the build artifact
Right click on the build artifact displayed in the Jenkins Build Output above. This will give you the full URL for the build artifact - something like this https://{jenkins-url}/job/DevToolStack/90/artifact/cdk8s/dist/terraform-operator.k8s.yaml
Add a new HTTP file artifact to the pipeline replacing the build number with the BUILD field from the properties using the following variable - ${trigger.properties['BUILD']} like this
Jenkins supports various triggering methods, cron, webhook, URL, upstream, etc. All triggers should be defined in the triggers block of the pipeline. cron is something like Unix/Linux cron. To write a cron trigger, use cron "MINUTE HOUR DOM MONTH DOW" syntax.
Create the job to be triggered. Type the project name “triggeredJob” (it will be triggered with this name in the pipeline) and select the freestyle project. ...
Create the Pipeline to trigger. Type the project name “parentJob” and select the pipeline project. ...

In Jenkins, "build periodically," "pollSCM," and "webhook" are different methods of triggering Jenkins jobs. Each method has its own use case and implementation details.
Steps To Trigger Jenkins Builds Remotely And Pass Parameters
Step 1 : Open Jenkins dashboard and create a new item. Step 2 : Give the new item a name and select pipeline . Step 3 : Add some build parameters by selecting `This project is parameterized` .
You can add a new trigger by going to your project's Settings ➔ CI/CD under Triggers. The Add trigger button will create a new token which you can then use to trigger a rerun of this particular project's pipeline.
Declarative vs. Scripted pipelines in Jenkins. Jenkins offers two types of syntax to create pipelines: declarative and scripted. Declarative syntax has recently been added to Jenkins to make pipeline code richer and more readable.
On the General tab, you may give some description about his pipeline. On the Datalog Tagging tab, check “GitHub project”, and put your project URL in the field. On the Build Triggers tab, check “GitHub Pull Request Builder”. Then the GitHub API credentials is automatically filled in.
Stage. A stage block defines a conceptually distinct subset of tasks performed through the entire Pipeline (e.g. "Build", "Test" and "Deploy" stages), which is used by many plugins to visualize or present Jenkins Pipeline status/progress.
Stage block descriptions are displayed in the Jenkins UI. Here we are defining three stages – Build , Test , and Deploy . Each of them can contain specific scripted code that performs the required operations.
A pipeline describes the flow of data from the origin system to destination systems and defines how to transform the data along the way.A job is the execution of a pipeline. A job instance defines the pipeline to run and the engine that runs the pipeline.
