Как установить файл docker на стадии конвейера jenkin

Question

У меня есть простой JenkinsFile, загруженный в мое git репо

pipeline {
    agent any
    stages {
        stage('Initialize'){
            def dockerHome = tool 'myDocker'
            env.PATH = "${dockerHome}/bin:${env.PATH}"
            }
        stage('Push to Docker Registry'){
    withCredentials([usernamePassword(credentialsId: 'dockerHubAccount', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {
        pushToImage(CONTAINER_NAME, CONTAINER_TAG, USERNAME, PASSWORD)
    }  
        }
    }
}

В jenkins я создал проект конвейера и только что прошел путь к моему git репо. my Docker определен в глобальной конфигурации инструмента. Учетные данные dockerhub определены в jenkins-> credentials.

При сборке я получаю следующее:

Я уверен, я делаю любую небольшую ошибку. Пожалуйста, перенаправьте меня в правильном направлении.

Вам нужно обернуть свой код в несколько этапов внутри стадии, как показано ниже.

pipeline {
agent any
stages {
    stage('Initialize'){
        steps {
                def dockerHome = tool 'myDocker'
                env.PATH = "${dockerHome}/bin:${env.PATH}"                }
        }
    stage('Push to Docker Registry'){
        steps {
            withCredentials([usernamePassword(credentialsId: 'dockerHubAccount', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {                
            pushToImage(CONTAINER_NAME, CONTAINER_TAG, USERNAME, PASSWORD)
            }            
        }  
    }
}}
