Kubernetes - Service MeshYou deployed a service mesh but notice that traffic is not routed through the sidecar proxies. What is a likely cause?AThe namespace was not labeled for sidecar injectionBThe application code lacks the communication libraryCThe Kubernetes cluster is missing the container runtimeDThe service mesh requires manual pod restarts to workCheck Answer
Step-by-Step SolutionSolution:Step 1: Check sidecar injection setupIf the namespace is not labeled, sidecar proxies are not injected, so traffic bypasses them.Step 2: Eliminate other causesApplication code and container runtime issues do not prevent sidecar injection; manual restarts are not required if injection is automatic.Final Answer:The namespace was not labeled for sidecar injection -> Option AQuick Check:Missing namespace label blocks sidecar injection [OK]Quick Trick: Label namespace to enable sidecar injection [OK]Common Mistakes:Blaming app code for missing sidecar trafficAssuming container runtime causes injection failureThinking manual pod restart is always needed
