Hoping someone can point me in the right direction.
I have just started to look at the Jenkins pipeline and am trying to work out how to trigger a parameterized build for a job that already exists using the Jenkinsfile
In my Jenkinsfile i have
node {
stage 'Build My Job'
build job: 'my-build'
}
I need to be able to pass a branch name from the Jenkinsfile config to the job that is running? If i am misunderstanding anything then please let me know
Thanks
Instead of starting with a Jenkinsfile, it's easier to start with a pipeline job in which you can directly edit the pipeline script. By clicking the 'Pipeline Syntax' link you can open the snippet generator, where you can generate the Groovy for a particular step:
This Snippet Generator will help you learn the Groovy code which can be used to define various steps. Pick a step you are interested in from the list, configure it, click Generate Groovy, and you will see a Groovy statement that would call the step with that configuration. You may copy and paste the whole statement into your script, or pick up just the options you care about. (Most parameters are optional and can be omitted in your script, leaving them at default values.)
In the configuration page select 'This project is parameterized' and sleect parameter type and enter parameter name
You can access this new parameter value in you jenkinsfile using 'env.parameterName'

Does anyone have the magic maven/gradle invocation to compile a set of jenkins pipeline DSL groovy files?
Groovy is not compiled (like C#), it is interpreted.
Depending on exactly what you are trying to test potential options are:
Jenkins Groovy Script Console under Manage Jenkins. Note: You will need to be an Admin to be able to access this.
Pipeline Syntax Generator. It is improving. Go to a build of Pipeline job and in the LHS menu you will see a 'Pipeline Syntax' link. Some items require you to first select Pipeline: Steps from the first dropdown.
I've created a Jenkins job of type "Pipeline", and used an inline pipeline script. Now I'd like to put the script under version control and use the "Pipeline script from SCM" option (I think, I don't have to describe the merits of this).
However, our version control system (CA SCM) is not well supported in Jenkins: I couldn't make the plugin to check out anything.
We do have, however, some scripts for working with CA SCM that allow to check out things reliably.
So, my question is: Is it possible (and how) to have the Jenkinsfile under version control, do the check out for it by a custom script (e.g. using a .bat command) and then have the pipeline executed as if the Jenkinsfile had been extracted by the "Pipeline script from SCM" option?
I.e., as I understand it, I need a command in the pipeline plugin to execute a given Jenkinsfile.
You could try to use the feature "Prepare an environment for the build" from the "Environment Injector Plugin" (https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin) and provide a script file (or inlined content) to execute.
When a job is building in Jenkins, how can I check if "Restrict where this project can be run" is checked or not without installing any plugin.
I thought it would show in environment variables but i didn't see it.
Jenkins uses assignedNode property for restricting the project to label/node.
You can get this property using
/config.xml - Look for assignedNode property
Using groovy (run this from master console)
def job = Jenkins.instance.getItemByFullName('')
println job.getAssignedLabel().getExpression()
For more information, check - getAssignedLabel
Hope this helps
The groovy script doesn't give correct results for pipeline scripts, however, if the script uses the agent { 'xy' } - directive. The groovy will always show master - and for the initial pipeline script, that is of course always true. Something to keep in mind.
Prior Jenkins2 I was using Build Pipeline Plugin to build and manually deploy application to server.
Old configuration:
That works great, but I want to use new Jenkins pipeline, generated from groovy script (Jenkinsfile), to create manual step.
So far I came up with input jenkins step.
Used jenkinsfile script:
node {
stage 'Checkout'
// Get some code from repository
stage 'Build'
// Run the build
}
stage 'deployment'
input 'Do you approve deployment?'
node {
//deploy things
}
But this waits for user input, noting that build is not completed. I could add timeout to input, but this won't allow me to pick/trigger a build and deploy it later on:
How can I achive same/similiar result for manual step/trigger with new jenkins-pipeline as prior with Build Pipeline Plugin?
This is a huge gap in the Jenkins Pipeline capabilities IMO. Definitely hard to provide due to the fact that a pipeline is a single job. One solution might be to "archive" the workspace as an "artifact" (tar and archive **/* as 'workspace.tar.gz'), and then have another pipeline copy the artifact and and untar it into the new workspace. This allows the second pipeline to pickup where the previous one left off. Of course there is no way to gauentee that the second pipeline cannot be executed out of turn or more than once. Which is too bad. The Delivery Pipeline Plugin really shines here. You execute a new pipeline right from the view - instead of the first job. Anyway - not much of an answer - but its the path I'm going to try.
EDIT: This plugin looks promising:
https://github.com/jenkinsci/external-workspace-manager-plugin/blob/master/doc/PIPELINE_EXAMPLES.md
I have a jenkins job that runs some tests and promotes the build if all tests pass.
I then have a second job that has a 'Promoted build parameter' which is used for deployments.
THe idea is that the deply job should let you pick one of the prompted builds for deploying. The issue I'm having is that I can pick a promoted build, but I have not idea how I access information about the build.
I've named the build parameter
SELECTED_BUILD
And according to the docs this should then be available via the environment.
The problem is that it doesn't seem to be bound to anything.
If I run a build step to exectute this sheel script:
echo $SELECTED_BUILD
echo ${SELECTED_BUILD}
The values are not interpolated / set.
Any idea how I can access the values of this param?
Many Thanks,
Vackar
Inject the information as variable user jenkins plugin (eject evn variable).
while triggering parameterized build on other job, pass above variable as parameter to next job.
