Issue/Introduction

DX  21.3 exportImages fails 

when running  ./AIOpsManagement.sh --exportImages

produced java exceptions and doesn't save the images (in default path ./images)

The installation (option --install) works without problems. Here you see the script output:

... Utility can save/load images under following directories:
/root - mount to base directory of AIOpsManagement.sh
/mount-home - your user home directory.
Subdirectories can be created under these parent directories.
For example, specifying the path as /root/images or just images will create images subdirectory in AIOpsManagement base directory.
Specify the path to export images [images]:
Install will use images from registry default-route-openshift-image-registry.apps.mydomain

Environment

Release : 21.3

Component :

Cause

The issue is in the shared step for importing images.tar.gz. In the installer folder there is dxi.input.vars.yaml file with "imageSource=use_existing" and because of this it skips importing images tar file.

 

Resolution

To bypass the issue you can temporarily remove dxi.input.vars.yaml from the installer folder for export/import images and copy it back before installation.
