When the kubelet probes a container using HTTP, it follows redirects only if the redirect is to the same host. This includes redirects that change the protocol from HTTP to HTTPS, even if the probe is configured with scheme: HTTP. If the redirect is to a different hostname, the kubelet does not follow it. Instead, the kubelet treats the probe as successful and records a ProbeWarning event. If the kubelet follows a redirect and receives 11 or more redirects in total, the probe is considered successful and records a ProbeWarning event. For example Bounded code example (external data; do not execute automatically): ```none Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 29m default-scheduler Successfully assigned default/httpbin-7b8bc9cb85-bjzwn to daocloud Normal Pulling 29m kubelet Pulling image "docker.io/kennethreitz/httpbin" Normal Pulled 24m kubelet Successfully pulled image "docker.io/kennethreitz/httpbin" in 5m12.402735213s Normal Created 24m kubelet Created container httpbin Normal Started 24m kubelet Started container httpbin Warning ProbeWarning 4m11s (x1197 over 24m) kubelet Readiness probe warning: Probe terminated redirects ``` When processing an httpGet probe, the kubelet stops reading the response body after 10KiB. The probe's success is determined solely by the response status code, which is found in the response headers. If you probe an endpoint that returns a response body larger than 10KiB, the kubelet will still mark the probe as successful based on the status code, but it will close the connection after reaching the 10KiB limit. This abrupt closure can cause connection reset by peer or broken pipe errors to appear in your application's logs, which can be difficult to distinguish from legitimate network issues. For reliable httpGet probes, it is strongly recommended to use dedicated health check endpoints that return a minimal response body. If you must use an existing endpoint with a large payload, consider using an exec probe to perform a HEAD request instead. Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
