jenkins - Cloudbees Jenkins插件无法启动容器

Question

我正在尝试设置jenkins以将Docker容器用作构建环境，但无法启动容器。我设置了一个工作，将cloudbees/java-build-tools图像作为测试开始

我可以从jenkins容器手动启动容器:

jenkins@1ae38451b61e:/$ /var/jenkins_home/tools/org.jenkinsci.plugins.docker.commons.tools.DockerTool/1.7.1/bin/docker -H tcp://192.168.0.193:4243 run --rm -ti cloudbees/java-build-tools bash
jenkins@68dde85393e3:/$ exit
jenkins@1ae38451b61e:/$ 

主机/守护程序和jenkins / client上的Docker版本均为1.7.1。

注意到“详细”复选框可以帮助我找到原因。

该命令的这一部分揭示了问题:

$ docker -H tcp://192.168.0.193:4243 run --volume /var/jenkins_home:/var/jenkins_home:rw --volume /tmp:/tmp:rw cloudbees/java-build-tools bash
Error response from daemon: Cannot start container 2d50f5bf2672da535a9f977d2b5daf1e4b10611f4e601256b49e15188f754089: [8] System error: no such file or directory

该插件正在docker主机上远程运行命令，该主机尝试挂载/ var / jenkins_home /目录，该目录仅在jenkins容器内部位于客户端。

我通过使用 -v /var/jenkins_home/:/var/jenkins_home/和 -v /tmp/:/tmp/重新启动jenkins容器来解决此问题
/tmp是必需的，因为jenkins存储shell脚本以像 /tmp/hudson7422451548770990961.sh一样在那里执行。
