Which issue(s) this PR fixes
In some environments, liveness/readiness probe by
exec
fails occasionally whiletcpSocket
always succeeds. The failure may be caused by `containerd but we have no evidence.When secure serving is enabled, a plain tcp connection (without TLS) will cause an EOF error in the pod logs. So we need to use
httpGet
.
