1、Kubernetes: requesting flag for "kubectl logs" to avoid 5-minute timeout if no stdout/stderr
When running kubectl logs --follow on a pod, after 5 minutes of no stdout/stderr, we received:
$ kubectl --kubeconfig=config --namespace=foo logs --follow foo-oneoff-w8npn --container bar ###################################### # # # /system_tests/test_derp.py (1/4) # # # ###################################### RESULTS: [/system_tests/test_derp/TestDerp] Ran 4 tests in 130.044 s, ALL TESTS PASSED ###################################### # # # /system_tests/test_fuzz.py (2/4) # # # ###################################### error: unexpected EOF
解决方案：
For posterity, the problem here is that we're using haproxy to serve a VIP to balance HA Kubernetes masters.
Specifically we're using HA-Proxy v1.4.21, and we have this in our haproxy cfg:
defaults timeout client 500000 timeout server 500000
