@sbmrvv
After verifying your inventory file, I don't seem to find proper variables required for offline installation.
Did you follow the instructions?
Step 1 Download offline files, copy them to offline environment and run nginx as repo
Step 2 Uncomment files repo and specify your own IP/URL (step 1)
I recently deployed offline cluster and everything worked flawlessly.
from kubespray.

I'm new in kubespray and I think I'm a little confused. Needs help !
Local test env:
Harbor registry https://192.168.33.80:444 (with a self-signed certificate) and Nexus http://192.168.33.80 (for testing purposes and in case harbor fails with images, can be used for files and images) and an Nginx Repo http://192.168.33.81/rpm (can be used for files)
Please guide me, If I did wrong. To get list of images I ran generate_list.sh, it gave me list of usage images(images.list) and files(files.list)
./generate_list.sh
[WARNING]: Found both group and host with same name: geo-api
[WARNING]: Skipping callback plugin 'ara_default', unable to load

So, I manually installed all required images from images.list then pushed to my local repo. After running playbook it gives:
The conditional check 'download.enabled' failed. The error was: error while evaluating conditional (download.enabled): {{ download_defaults | combine(item.value) }}: 'item' is undefined. 'item' is undefined. {{ download_defaults | combine(item.value) }}: 'item' is undefined. 'item' is undefined
The error appears to be in './kubespray/roles/download/tasks/main.yml': line 19, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: Download | Download files / images

I read offline installation carefully. It seems I had to give a value to IMAGES_FROM_FILE for manage-offline-container-images.sh create
from kubespray.

./manage-offline-container-images.sh register worked perfectly too.
