如何在jenkins管道作业中运行docker命令

在我的Manage Jenkins>中Global Tool Configuration,我已经配置了一个名为"docker"的工具,如下所示:

name:                   docker
install automatically:  CHECKED
docker version:         latest

然后我所拥有的jenkinsfile就是以下内容,而不是其他内容:

node {
    DOCKER_HOME = tool "docker"
    sh """
        echo $DOCKER_HOME
        ls $DOCKER_HOME/bin/
        $DOCKER_HOME/bin/docker images
        $DOCKER_HOME/bin/docker ps -a
    """
}

我收到这样的错误" 无法连接到Docker守护程序.这个主机上是否运行了docker守护程序？ ".

以下是完整的console log:

在管道到达运行docker命令的行之前,如何确保docker守护程序/服务正在运行/启动.

有没有其他本地docker-build-step插件方式来实现我在这里做的事情？像docker ps -a或docker images或docker build -t？

假设我选择的节点尚未在我的主机中安装/运行docker/docker-engine.这是tool命令在节点中自动安装docker 的目的(如果它尚未存在).
