Microservices - Orchestration with Kubernetes
What does a readiness probe primarily check in a microservice container?
AIf the container is ready to accept traffic
BIf the container is running without crashes
CIf the container has enough CPU resources
DIf the container's disk space is sufficient
Step-by-Step Solution
Solution:

  1. Step 1: Understand readiness probe purpose

    Readiness probes check if a container is ready to serve requests, meaning it has initialized and is healthy enough to receive traffic.

  2. Step 2: Differentiate from liveness probe

    Liveness probes check if the container is alive (not crashed), but readiness probes focus on readiness to accept traffic.

  3. Final Answer:

    Readiness probes check if the container is ready to accept traffic -> Option A

  4. Quick Check:

    Readiness probe purpose = Accept traffic [OK]
Quick Trick: Readiness = ready for traffic, liveness = alive and running [OK]
Common Mistakes:
MISTAKES
  • Confusing readiness with liveness probe
  • Thinking readiness checks resource usage
  • Assuming readiness checks container crashes
