Improves plugin storage fix and reduces the image size #226

Closed hrishin closed 5 years ago

hrishin commented 5 years ago

In last optimization, system used to link '/opt/openshift/plugins/*' directory contents to , which contains decompressed plugins directories in order prevent jenkins to extract plugins on gluster storage. However, Jenkins used to override decompressed plugin contents to make this patch effective Jenkins requires another boot. Another issue was, how to cleanup existing plugins from gluster storage when rolling out this plugin fix patch.

This patch creates symbolic link between the directory rather than directory contents, which essentially eliminates the need to reboot jenkins twice to get decompressed plugins content effective. Now symbolic link is present between a directory, so let jenkins extract the plugins in to directory, hence to reduce the image size system is not decompressing plugins content upfront.

This patch also takes care of cleaning up the plugins from gluster storage.
