How to Investigate a Kubernetes Container That Exits After a Successful Health Check

A container can pass startup checks and then exit when its main process finishes, encounters a later error, or receives a termination signal. Health probes alone do not explain lifecycle.

What to check

Review container state and exit code, previous logs, events, command and arguments, signals, and controller type. Compare intended long-running service behavior with a job.

Recommended next step

Match the workload controller to the process lifecycle and handle failures explicitly. Informatix Systems can troubleshoot Kubernetes workloads.
