Subject: [PATCH 3/3] Update the liveness probe to verify postgres connectivity
|
|
|
|
Change the tillerLivenessProbeTemplate to test the connectivity to the
|
|
postgres backend. We will override the periodSeconds and
|
|
failureThreshold when installing the helm chart to trigger a restart of
|
|
the tiller pod over a swact when the postgres DB/server moves from one
|
|
controller to the other.
|
|
|
|
This will help guarantee that the tiller connection is always
|
|
reestablished if the connectivity to the postgres backend fails.
|
