Kube runner gives 404

[andrewzah]

Hi, I’m running drone (2.0.1 on alpine3.13) and drone-runner-kube (commit f71d613c on alpine3.13).

When I start the runner, it gives this 404 error. Is it a version issue with drone server?

@andrewzah,

Most common reason for this issue could be:

1. Problem with networking (this is the most likely root cause)
2. incorrect host address
3. incorrect secret

It seems to be an API version mismatch?
I am now on Drone 2.7.2 and docker-runner 1.8.0.
