Jenkins cannot delete root-owned files/folders in jenkins-owned directories

 In this post we will discuss abut most frequent issues faced in Jenkins build.

When you try to use docker image to run your jobs you may end up in creating some file which are created by root user ( from Docker image ). In this case from next build onwards we will see some issues to clean old workspace. Even if you try to use cleanUP workspace plugin you will end up with permission issues. 

To avoid this issue please follow below steps
1) Install acl package based on your distribution.

 Debian

apt-get install acl

 Ubuntu

apt-get install acl

 Alpine

apk add acl

 Arch Linux

pacman -S acl

 Kali Linux

apt-get install acl

 CentOS

yum install acl

 Fedora

dnf install acl

2) Follow below steps to clean workspace and apply acl on workspace folder. After this change you will see any file or folder which is created in workspace folder will have complete ownership of jenkins user. 

$ rm -rf workspace # to avoid any inconsistencies in existing files
$ mkdir workspace
$ sudo setfacl -dm 'u:<your_jenkins_user_name>:rwx' workspace
