声明式pipe道中的Jenkins docker agent：未find文件
当试图从https://github.com/jenkinsci/pipeline-model-definition-plugin/wiki/Controlling-your-build-environment执行示例时：
pipeline { agent { docker 'node' } stages { stage("testing 123") { steps { sh 'node --version' } } } } 我得到以下输出：

docker安装在服务器上，并在PATH中：图像内置:-)（ docker pull命令在pipe道开头成功）
我在org.jenkinsci.plugins.docker.workflow.client.DockerClient上添加了一个logging器，结果如下：
Apr 07, 2017 3:56:18 PM FINE org.jenkinsci.plugins.docker.workflow.client.DockerClient Executing docker command docker -v
我也尝试在一个正规经纪人的舞台上推出一个docker工人，同样的问题：
pipeline { agent any stages { stage("testing 123") { agent { docker { image 'ubuntu:16.04' } } steps { sh 'uname -a' } } } }
使用Docker.Pipeline 1.10
这似乎与节点上的PATHconfiguration问题有关，但我找不到在哪里。
如果我在节点控制台中运行org.jenkinsci.plugins.docker.commons.tools.DockerTool.getExecutable("docker", Jenkins.getActiveInstance(), null, null) ，我得到正确的（现有的，可执行的）dockerpath。
任何想法 ？
非常感谢！
为zshell（或其他文件）添加~/.zshenv以将docker放入path中。 我做到了这一点，问题解决了：
$ cat ~/.zshenv export PATH=/usr/local/bin:$PATH
它看起来像docker inspect不运行在docker pull相同的环境。
在我的Mac上， docker pull失败，然后我configuration了node / agent将这个Name: PATH, Value: /usr/local/bin:$PATH到Environment variables ，然后docker pull将正常运行。 docker inspect失败。
然后像上面那样加~/.zshenv （并重新启动节点/代理）， ~/.zshenv docker inspect最终工作。
你可以运行一个类似于sh "docker 'node'"的shell命令
我所做的是使用Jenkinsfile和Dockerfile（因为我编辑我的图像），并让Jenkinsfile调用一个脚本
docker build --tag=image-name . docker run --rm --name=image-name-container image-name \ ./someScript.sh \ -j ${SCRIPT_PARAM1} \ -u ${SCRIPT_PARAM2} > ${DOCKER_OUTPUT_FILE_NAME}
在里面。
