I am setting an IP whitelist in my kubernetes ingress config via the annotation ingress.kubernetes.io/whitelist-source-range. But, I have different whitelists to apply for different environments (dev, staging, production, etc.) Therefore, I have a placeholder variable in my deploy.yaml that I find/replace with the appropriate IP whitelist based on the environment.
At the moment, for dev, I am passing an empty string as the whitelist because it should be able to receive traffic from all IPs, which currently works as intended. But, logs in nginx-ingress-controller complain about the following:
error reading Whitelist annotation in Ingress default/{service}: the
annotation does not contain a valid IP address or network: invalid CIDR
address:How do I set a proper whitelist-source-range to allow all IPs but not create noisy error logs like the one above?
Yes, it will give you error reading according to the ingress annotations ip whitelist. It suspecting a IP range or Multiple IP ranges, even you didn't put a value, you will get the reading error as well, to get ride of this error and allow all the IPs put 0.0.0.0/0 this will bypass and fix your issue.
