Title: Message Title

Daniel Sorensen, indeed, it works, and that's a good example.

I just want to note that passing environment argument to the docker command will override original PATH value defined in image with the one from Jenkins host, and in some conditions it may produce not the result you expect (this was actually described in JENKINS-43590). Here is such example:

 
                                                                pipeline {
    agent any
    environment {
        NODEJS_VERSION = "NodeJS 12.16.2"
    }

    stages {
        stage('Nodejs inside OpenJDK container 1') {
            agent {
                docker {
                    reuseNode true
                    image 'openjdk:11.0-jdk-slim'
                    args """
                        -v ${JENKINS_HOME}/tools:${JENKINS_HOME}/tools
                        -e PATH="${PATH}:${tool("${NODEJS_VERSION}")}/bin"
                    """
                    // Original PATH from openjdk image:
                    // PATH=/usr/local/openjdk-11/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
                }
            }
            tools { nodejs "${NODEJS_VERSION}" }

            environment {
                PATH_JENKINS_ORIGINAL = "${PATH}"
            }

            steps {
                sh 'env | sort'
                sh 'node --version'

                catchError(buildResult: 'SUCCESS',
                           stageResult: 'FAILURE',
                           message: 'cannot find java') {
                    sh 'java --version'
                }
            }
        }

        stage('Nodejs inside OpenJDK container 2') {
            agent {
                docker {
                    reuseNode true
                    image 'openjdk:11.0-jdk-slim'
                    args """
                        -v ${JENKINS_HOME}/tools:${JENKINS_HOME}/tools
                    """
                }
            }

            tools { nodejs "${NODEJS_VERSION}" }

            environment {
                NODEJS_BIN_PATH = "${tool("${NODEJS_VERSION}")}/bin"
                PATH_JENKINS_ORIGINAL = "${PATH}"
            }

            steps {
                sh '''
                    env | sort
                    export PATH=${PATH}:${NODEJS_BIN_PATH}
                    node --version
                    java --version
                '''
            }
        }
    }
}
