configmap-reload container showing following logs when configmap is updated:

2021/10/26 18:13:56 Watching directory: "/etc/config" 2021/10/26 18:50:08 config map updated 2021/10/26 18:50:08 performing webhook request (1/1) 2021/10/26 18:50:08 error: Received response code 405 , expected 200 2021/10/26 18:50:18 error: Webhook reload retries exhausted

however curl from inside configmap-reload container to same webhook gets expected 200 response and prometheus configuration reloads successfully

Could you paste the command you have in your configmap-reload pod?

bfitzelle commented 3 years ago

sure - command running in configmap-reload container is:

/configmap-reload --volume-dir=/etc/config --webhook-url=http://127.0.0.1:9090/prometheus//-/reload

I would find very odd if the return is really a 405. The only different between your pod's command and the curl you pasted before is the url on your pod seems to have // two slashes.

Have you tried adding retries to the request?
