One component can fail while the rest of the system looks healthy. Here, a pod process is alive but the deployment never becomes Ready due to a failed readiness probe. Treat the unaffected path as a control for diagnosis.
What the user actually sees
Primary symptom. A pod process is alive but the deployment never becomes Ready due to a failed readiness probe. Record the precise point of failure and whether the same input, account or connected device succeeds in another supported mode. That working comparison establishes the scope of the repair.
Separate configuration from service faults
The first hypothesis is a mismatch in the failing path. Inspect readiness probe path, port and the container actual ready condition. The second is a lower-level state that the interface may not show: compare startup latency, service dependencies and probe failures from inside the pod network namespace. A third possibility is a feature or version limitation, which should be checked against supported documentation before a reset.
For this Release Engineering issue, capture workflow commit, runner version, pod events and environment policy and compare the same job in a disposable branch or non-production namespace. Preserve the last known working configuration so you can tell whether a successful retry came from an actual correction or a temporary recovery.
Read the evidence
| What you observe | What it suggests | Focused response |
|---|---|---|
| A pod process is alive but the deployment never becomes Ready due to a failed readiness probe | The failure affects the specific workflow described here; the entire system is not necessarily broken. | Inspect readiness probe path, port and the container actual ready condition. |
| The basic comparison exposes a difference between a working and failing configuration. | A local setting, version, account context or device route deserves attention. | Fix the endpoint or probe configuration to represent genuine application readiness. |
| The same failure persists after a reversible correction. | A deeper dependency or compatibility issue may remain. | Compare startup latency, service dependencies and probe failures from inside the pod network namespace. |
Before changing anything: Do not remove readiness gates merely to make a failing deployment appear healthy. Save a screenshot or anonymized log line, record the previous setting, and back up relevant user data. Do not reset every related service just because one test fails.
Choose a recovery route. The Beginner path checks inspect readiness probe path, port and the container actual ready condition. The Advanced path investigates compare startup latency, service dependencies and probe failures from inside the pod network namespace. They address different evidence; use the path that matches your result.
Step-by-Step Troubleshooting
Choose the Beginner route for reversible checks or Advanced for evidence-driven diagnosis.
Preserve the current working state
A pod process is alive but the deployment never becomes Ready due to a failed readiness probe. Before editing settings, note the exact time, affected account or device, and whether it started after an update, move, hardware change or network change. This is the baseline for the Kubernetes Readiness Probe Fails While the Container Keeps Running guide.
Check readiness probe path, port and the container actual ready
Inspect readiness probe path, port and the container actual ready condition. Observe whether the symptom changes. A clean comparison tells you which part of the process is healthy and avoids unnecessary resets.
Adjust the endpoint or probe configuration to represent genuine
Fix the endpoint or probe configuration to represent genuine application readiness. Change only this variable, record its former value, and try the failing action once. If there is no improvement, restore the prior configuration before exploring the Advanced route.
Verify the pod becomes Ready only when the actual workload
The pod becomes Ready only when the actual workload accepts requests. Repeat using the same account, network, file, title or hardware condition that previously failed. Do not count a different test as confirmation.
Inspect supporting logs
Collect the error text or state relevant to Kubernetes Readiness Probe Fails While the Container Keeps Running. Record workflow commit, runner version, pod events and environment policy; anonymize account IDs, public IPs and secret-bearing log fragments before sharing.
Inspect startup latency, service dependencies and probe failures
Compare startup latency, service dependencies and probe failures from inside the pod network namespace. Record the difference between successful and failed cases and keep the first meaningful error rather than the last cascade message.
kubectl describe pod example-pod -n example-namespaceRule out related configuration drift
Where practical, compare the same job in a disposable branch or non-production namespace. If the alternate case works, return to the single configuration difference instead of changing multiple services. Use the vendor-supported method for your current version.
Verify and record results
The pod becomes Ready only when the actual workload accepts requests. Leave the previous value documented for rollback, then monitor one normal operating cycle. If symptoms recur, attach the sanitized evidence to a vendor or administrator support request.
What not to assume
After the first corrective action, interpret the result carefully. If the original task now works, leave the other settings unchanged. If it still fails, compare startup latency, service dependencies and probe failures from inside the pod network namespace. Compare the same job in a disposable branch or non-production namespace rather than adding random fixes on top of one another.
For escalation, retain workflow commit, runner version, pod events and environment policy, the original output, and a single before/after comparison. Redact passwords, tokens and personal data. A support agent can then distinguish the same job in a disposable branch or non-production namespace from a general outage without repeating risky actions.
Optional targeted diagnostic
View events and probe configuration for your authorized pod. Commands below are illustrative and must be run only on systems you are authorized to inspect.
kubectl describe pod example-pod -n example-namespaceVerification procedure
Pass condition: The pod becomes Ready only when the actual workload accepts requests. The validation must exercise the same path that failed originally. A successful settings screen, single ping, application homepage or idle system is not enough if the original failure appears during a different action.
Repeat the test under the original conditions once after a safe relaunch, reconnect or new session. For intermittent failures, record the time and the difference between a clean result and a failed one instead of claiming success from a single attempt.
Prevention and next steps
If the problem persists, restore any test-only settings, preserve the evidence and stop before destructive reset, firmware flash or credential recreation. Give official support the exact symptom, the first failing timestamp and what the comparison established. Do not remove readiness gates merely to make a failing deployment appear healthy.
Prevent recurrence: Document the working correction: Fix the endpoint or probe configuration to represent genuine application readiness. Retain the accepted result (the pod becomes Ready only when the actual workload accepts requests) as a future regression test after configuration, software or hardware changes.
Solution Checklist
Questions specific to this fault
How do I know the symptom is actually resolved?
The pod becomes Ready only when the actual workload accepts requests. A generic diagnostic test outside the affected workflow is not a substitute.
Should I reset or reinstall everything first?
No. Inspect readiness probe path, port and the container actual ready condition. Then choose the smallest supported intervention: fix the endpoint or probe configuration to represent genuine application readiness. Preserve recoverable settings and user data.
What should I include in a support request?
Provide the exact failing action, product and version, time, non-sensitive log evidence, and this deeper observation: Compare startup latency, service dependencies and probe failures from inside the pod network namespace. Do not include credentials or private customer data.
