Kubernetes backoffLimit Error Deep Dive: From Failure Loops to Reliable Rollouts
Kubernetes Jobs and Pods retry automatically when failures occur, but once the restart threshold is exceeded, they hit the Kubernetes backoffLimit error — a state where Kubernetes stops trying altogether. This leads to stalled deployments. It’s not uncommon either: 37% of organizations report that half or more of their workloads need configuration review, and backoffLimit […]

Kubernetes Exit Code 127 Error: Entrypoint Failures, Pod Restarts, and Monitoring with CubeAPM
Kubernetes powers over 84% of containerized workloads in production. But with scale comes runtime errors that can quietly derail rollouts. One such issue is Kubernetes Exit Code 127 error, triggered when a container runs a missing command or binary. Often caused by misconfigured images or invalid entrypoints, it can stall deployments, push Pods into CrashLoopBackOff, […]

Kubernetes Exit Code 143 (SIGTERM) Error: Graceful Termination, Debugging, and Monitoring with CubeAPM
Kubernetes Exit Code 143 occurs when a container is stopped with a SIGTERM signal, usually during pod shutdowns, scaling, or rolling updates. While designed for graceful termination, missing preStop hooks, long-running processes, or misconfigured probes can turn it into failed rollouts. About 66% of organizations now run Kubernetes in production CNCF Survey, so recurring 143 […]
