我创建了一个 Jenkins 管道项目，它应该在 newman 容器中运行 newman 命令。Jenkins 从 Kubernetes 中的容器运行。我可以在管道中使用 docker.pull() 命令拉取图像而不会出现任何问题，但是当我想使用 docker.image("postman/newman").inside {...} 命令在容器内运行命令时，我收到以下错误消息：

似乎 docker 不见了，但我不明白为什么我能做一个 docker.image 或 docker.pull 如果是这种情况。谁能给我一些关于我做错了什么的建议？
我尝试使用不同的图像，但我收到了相同的错误消息。
我的管道如下所示：
pipeline {
agent any
environment {
USER_BIN = '/var/jenkins_home/user-bin'
DOCKER_HOST = 'unix:///var/run/docker.sock'
DOCKER_CONFIG = '/var/jenkins_home/.docker'
}
stages {
stage ('TestInsideContainer') {
steps() {
script {
env.PATH = "${tool 'docker'}/bin:${env.PATH}"
newmanimage=docker.image("postman/newman")
newmanimage.pull()
newmanimage.inside() {
sh 'newman --version'
}
}
}
}
}
}
