When applied at the top-level of the pipeline block no global agent will be allocated for the entire Pipeline run and each stage directive will need to contain its own agent directive.
If you're like my team then you like having user-friendly parameterized Jenkins Jobs that pipeline scripts trigger in stages, instead of maintaining all that declarative/groovy soup. Jenkins Pipeline for Continuous Delivery and Deployment Review the principles of continuous delivery and deployment, and learn how you can apply them by using your Jenkins pipeline as code. Execute the Pipeline, or stage, on any available agent. The Jenkinsfile For example: agent none label. For example: agent any none. Request a personal build in the RTC build definition associated with the Jenkins job. First create a Job parameter "personalBuild" type is String in the Jenkins pipeline job and set the default value to false. This simple pipeline has one stage (besides the default stage: Checkout SCM that pulls the jenkinsFile) with three steps. The matching *.txt, if present, can contain documentation, processed through the system’s configured markup formatter (so may really be HTML, Markdown, etc., though the txt extension is required). by The Groovy source files in these directories get the same “CPS transformation” as in Scripted Pipeline. Because of this, the most critical action item is to reduce the number of groovy calls that need to be made (this includes the many imports of groovy methods being used). Jenkinsfile is where Pipeline as Code is maintained, and it should be placed in the root directory of the source code. For a quick overview and highlights of the features in Jenkins 2.0, visit https://jenkins.io/2.0/. Example. In this "Jenkins Minute", you see how customize your Jenkins Pipeline execution environment using a Dockerfile. For a Pipeline, groovy code *always* executes on master which is why it does use master resources. Both may be used to define a Pipeline in either the web UI or with a Jenkinsfile, though it’s generally considered a best practice to create a Jenkinsfile and check the file into the source control repository. An approach that works well for us is to put parts of the pipeline (those that all projects have in common) or even the whole pipeline into a Jenkins shared library. any. In your pipeline script, you can check whether the RTC build is a personal build or not as follows The first echoes a message, the second step will create a directory in the jenkins workspace named from-jenkins and the third a file test.txt inside the created directory. A pipeline is a script which gives Jenkins a series of jobs to do in a pipeline like manner (one after the other) these jobs can be as Jenkins code, scripts, build languages etc. Pipeline supports two syntaxes, Declarative (introduced in Pipeline 2.5) and Scripted Pipeline.Both of which support building continuous delivery pipelines. 2. I believe we already have a section that talks about the compromises related to performance optimized and maximum durability To read more about this, check out the Jenkins documentation… I wonder if there is a way to capture your experience and the experience of @res0nance in the Jenkins Pipeline docs. The following script (template.groovy) is defined as global variable in a Jenkins shared library. 3.
