This allows a node to be reserved for certain kinds of jobs.

Jenkins label expression

node label expression in Jenkins Scripted Pipeline Operators Specified in the descending order of precedence: (expression) - defines the associativity of the expression. !expression - negation. a && b - AND, both expressions must true. a || b - OR, either of the expression a or b may be true. a -> b - "implies" operator, equivalent with !a || b.

Jenkins label expression. LabelExpression.Or (Jenkins core 2.387 API) Accepts a visitor and call its respective "onXYZ" method based no the actual type of 'this'. Pipeline Syntax Execute the Pipeline, or stage, on an agent available in the Jenkins environment with the provided label. For example: agent { label 'my-defined-label' } Label conditions can also be used. For example: agent { label 'my-label1 && my-label2' } or agent { label 'my-label1 || my-label2' } node Jenkins Job Label Expression - NovaOrdis Knowledge Base Jenkins Job Label Expression Internal Jenkins Concepts Overview Defines a logical expression which determines which agents may execute builds for a project. This expression, when tested against the agent name and labels of each available agent, will be either true or false. Jenkins - restrict where this project can be run option with && (and ... The help in Jenkins should be pretty clear, as I recently rewrote it ;) A build runs on one machine at a time, and the expression defines which labels a particular node needs to have in order to start a build (e.g. "linux and mysql", so "machine1 and machine2" wouldn't make sense). But please do file a bug if you feel it's not clear.

[JENKINS-12998] Allows variable subistution for Job 'Restrict where ... Allow variable substitution for the 'Restrict where this project can be run' label expression field of the job configuration. Substitution of the form ${BRANCH} where BRANCH is a parameter to the job, will allow the job to run on any node with a label which matches BRANCH. Built-In Node Name and Label Migration Jenkins features using node labels are therefore potentially impacted by any such changes. These features include: Label assignments of various project types, both on the top level (e.g. Freestyle jobs) and within jobs (e.g. node statements in Scripted Pipeline, label parameters to agent sections in Declarative Pipeline, or Matrix Project axes). Using a Jenkinsfile Working with your Jenkinsfile Using environment variables Setting environment variables Setting environment variables dynamically Handling credentials For secret text, usernames and passwords, and secret files Secret text Usernames and passwords Secret files For other credential types Combining credentials in one step String interpolation Pipeline: Nodes and Processes Expressions can be written without whitespace, but including it is recommended for readability; Jenkins will ignore whitespace when evaluating expressions. Matching labels or agent names with wildcards or regular expressions is not supported. An empty expression will always evaluate to true, matching all agents. Examples master
