jenkins没有空间问题 – 在docker工人

我正在Docker里面运行Jenkins。 我收到以下空间问题。

gzip: /tmp/sbt_a74fec8a/xoquick-1.0.tar.gz: No space left on device java.lang.RuntimeException: Error gziping /tmp/sbt_a74fec8a/xoquick-1.0.tar.

Finished: FAILURE 

在泊坞窗我导航到/tmp文件夹

 cd /tmp/ 

接着

 df -h . Filesystem Size Used Avail Use% Mounted on /dev/mapper/docker-253:2-18350588-5a4c880a0e55c5b8a78ca16e7ef7fbedb7559cf07b3e249f81b88809901cca72 9.9G 9.1G 316M 97% / 

我有足够的空间留在里面。为什么工作失败？

我检查了这个http://www.ivankuznetsov.com/2010/02/no-space-left-on-device-running-out-of-inodes.html

inode也没有问题。有足够的inode可用。有人告诉我什么是问题？

Jenkins的工作通常会消耗更多〜300m的空间，包括所有构build的工件，上传到Docker容器的任何东西，版本控制检出的大小等等。

将其添加到root的crontab以定期清理旧的容器。 inputsudo crontab -e来编辑：

 SHELL=/bin/bash @daily (echo "Cleaning Docker images at $(date):"; docker rm $(docker ps -a -q); docker rmi $(docker images | grep '<none>' | tr -s ' ' | cut -d ' ' -f 3)) &>> /var/log/dockerClean.log 

（如果你喜欢sh ，你可以用2>&1 > /var/log/dockerClean.logreplaceSHELL行，如果你的系统默认是bash ，可以忽略它，不作任何改动）
