Kubernetes - Ingress

Anginx.ingress.kubernetes.io/limit-rps: "10" nginx.ingress.kubernetes.io/limit-rps-source-criteria: "ip"

Bnginx.ingress.kubernetes.io/limit-connections: "10" nginx.ingress.kubernetes.io/limit-connections-source-criteria: "ip"

Cnginx.ingress.kubernetes.io/limit-rpm: "10" nginx.ingress.kubernetes.io/limit-rpm-source-criteria: "ip"

Dnginx.ingress.kubernetes.io/rate-limit: "10" nginx.ingress.kubernetes.io/rate-limit-source: "ip"

Step-by-Step Solution

Solution:

Step 1: Identify correct annotation for requests per minute
The annotation 'limit-rpm' sets requests per minute limit.
Step 2: Specify source criteria as IP
Using 'limit-rpm-source-criteria' with value 'ip' applies limit per client IP.
Final Answer:
nginx.ingress.kubernetes.io/limit-rpm: "10" nginx.ingress.kubernetes.io/limit-rpm-source-criteria: "ip" -> Option C
Quick Check:
limit-rpm with source ip sets rate limit [OK]

Quick Trick: Use limit-rpm and source-criteria for rate limiting [OK]
