zypper clean
after zypper install
DOK-P1001Not cleaning cached package data after installation can result in higher image sizes. It is always recommended to clean the cached packages after installing them.
Please note that the clean-up must be performed in the same RUN
step as it creates a separate layer. Doing this in a different RUN
command would therefore result in a new layer, which will not help reduce the image size.
