Make it run on frontend as well #1752

Closed novellat closed 3 months ago

novellat commented 3 months ago

Describe the bug We can connect to the cluster by setting the endpoint and auth token. So theoretically, why shouldn't we be able to use it from frontend? Client Version e.g. 0.12.0

Server Version e.g. 1.19.1

To Reproduce Steps to reproduce the behavior:

Expected behavior A clear and concise description of what you expected to happen.

Example Code Code snippet for what you are doing

Environment (please complete the following information):

Additional context Add any other context about the problem here.

While this is potentially feasible, most Kubernetes clusters use a custom certificate authority root certificate. By design, most web browsers don't support loading custom root certificates for HTTP calls from within the browser for non-kubernetes security reasons.

Consequently, even if this client was ported to a browser HTTP/fetch library, the calls themselves would fail because https wouldn't work from the browser.

If someone wanted to add support for browser fetch in release-1.x we'd probably merge that PR, but it is of limited usefullness.

Thanks @brendandburns, that was a good observation, never realized you cannot bypass that in fetch!
