This was a enhancement that was previously delivered, and was reverted due to complications with Helm related installs. See this PR: https://github.com/nginx/kubernetes-ingress/pull/5528#issue-2287737063

Hi @shaun-nx thanks for reporting!

Be sure to check out the docs and the Contributing Guidelines while you wait for a human to take a look at this :slightly_smiling_face:

Cheers!

For environments that are not offline, but secured by a firewall, having the schema somewhere more specific than raw.githubusercontent.com would also help, as a workaround.

There also some rate limits for raw files serving, so will be nice to make schema validation in offline mode.

@anderius @psvmcc we're welcoming community contributions on this issue which involves more than just setting -skip-schema-validation in helm command, so if you've found a solution please feel free to suggest

Bump for this issue. This is also an issue for us to have to allow an egress connection to raw.githubusercontent.com in our firewall.
