We have been trying to build openSUSE Docker images locally. We could not find any official instruction for the same so far.

We found the instructions to build images using KIWI tool in the link below. But we are unsure if these are the official ones.

1. Please provide us with official instructions to build Docker Images for openSUSE leap in our local environment.
2. Please provide us with the link to the source code of openSUSE Leap 15.3

Thank you in advance.
