Kubernetes context deadline exceeded
A Kubernetes operation did not complete before its caller's deadline expired, indicating latency or unavailability somewhere in the request path.
context deadline exceededAlso searched as: DeadlineExceeded · request did not complete within requested timeout
What it means
The message is emitted by Go context handling across many Kubernetes components. It identifies a timeout boundary, not the slow layer; API server latency, etcd, admission webhooks, aggregated APIs, network paths and overloaded controllers can all be responsible.
Typical trigger conditions
- Slow or unavailable admission webhook
- API server or etcd overload
- Unresponsive aggregated API
- Client timeout shorter than normal operation latency
First diagnostic checks
Identify the caller and operation
Capture the component, HTTP path or resource, timeout and correlation identifiers.
Check API readiness and latency
Compare API server health and request-duration metrics around the event.
kubectl get --raw='/readyz?verbose'
Inspect admission and extension dependencies
Review webhook and APIService availability before simply raising the client timeout.
Version and platform notes
Timeout flags, tracing and metrics vary by client and Kubernetes release; use component-specific documentation.
