Use a lightweight executor for a declarative pipeline stage (agent none)

Question

I\'m using Jenkins Pipeline with the declarative syntax, currently with the following stages:

1. Prepare
2. Build (two parallel sets of steps)
3. Test

Answer 1

There is a workaround to use the same build slave in the other stages. You can set a variable with the node name and use it in the others.

ie:

pipeline {
    agent none
    stages {
        stage('First Stage Gets Agent Dynamically') {
            agent {
                node {
                    label "some-agent"
                }
            }
            steps {
                echo "first stage running on ${NODE_NAME}"
                script {
                  BUILD_AGENT = NODE_NAME
                }
            }
        }
        stage('Second Stage Setting Node by Name') {
            agent {
                node {
                    label "${BUILD_AGENT}"
                }
            }
            steps {
                echo "Second stage using ${NODE_NAME}"
            }
        }
    }
}
