Kops on a disconnected environment about kops

Its not clear for me how this is kops bug?

There is no way to setup kops for disconnected env... i can open a feature request if you want to

[zetaab]

there is way to install kops in disconnected environment. However, you must copy all assets first. It can be installed without any internet connectivity, you just need to have connectivity to single object storage.

https://kops.sigs.k8s.io/operations/asset-repository/

also you need to use kops channel: none (I cannot see this in your spec at all.. so its not none in that case. Default value is stable)

@zetaab Although I have added all assets files and containers into s3 and ECR and configured kops to use it, when looking at the nodeup logs I can see an error when trying to retrieve the s3 cluster-completed.spec even if I configure a s3 vpc endpoint.

That's because kops using the s3://bucket-name schema and the s3 vpc endpoint use the full s3 DNS name (bucket-name.s3.us-east-1.amazonaws.com).

As a result, kops cannot be used in a disconnected environment on AWS
