Cloudbees jenkins插件无法启动容器
我想安装jenkins使用docker容器作为构build环境，但我不能让它启动容器。 我build立了一个可以启动cloudbees/java-build-tools镜像的工作

我可以从jenkins容器手动启动容器就好了：
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:/$
Docker版本在主机/守护进程和jenkins /客户端上都是1.7.1。
注意到“详细”checkbox帮助我find原因。
这部分命令揭示了这个问题：
$ 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
该插件在docker主机上远程运行该命令，该主机试图挂载jenkins容器内仅存在客户端的/ var / jenkins_home /目录。
我通过用-v /var/jenkins_home/:/var/jenkins_home/和-v /tmp/:/tmp/
/tmp是必需的，因为jenkins存储shell脚本在/tmp/hudson7422451548770990961.sh执行。
