none label node docker dockerfile Common Options label 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. For example:  agent { label 'my-defined-label' } agent { node { label 'labelName' } }  behaves the same as  agent { label 'labelName' } , but node  allows for additional options (such as  customWorkspace ). 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.  docker  also optionally accepts an  args  parameter which may contain arguments to pass directly to a  docker run  invocation, and an  alwaysPull  option, which will force a  docker pull  even if the image name is already present. For example:  agent { docker 'maven:3- alpine' }  or Execute the Pipeline, or stage, with a container built from a  Dockerfile  contained in the source repository. In order to use this option, the  Jenkinsfile  must be loaded from either a Multibranch Pipeline, or a "Pipeline from SCM." Conventionally this is the  Dockerfile  in the root of the source repository:  agent { dockerfile true } . If building a  Dockerfile  in another directory, use the  dir option:  agent { dockerfile { dir 'someSubDir' } } . You can pass additional arguments to the docker build  …  command with the  additionalBuildArgs  option, like  agent { dockerfile { additionalBuildArgs '--build-arg foo=bar' } } . These are a few options that can be applied two or more  agent  implementations. They are not required unless explicitly stated. A string. The label on which to run the Pipeline or individual  stage . This option is valid for  node ,  docker  and  dockerfile , and is required for  node . 83 agent { docker { image 'maven:3-alpine' label 'my-defined-label' args '-v /tmp:/tmp' } }
