Subject: [PATCH] Enable override of mariadb-server probe parameters
|
|
|
|
Parameters are exported for startupProbe and readinessProbe.
|
|
They are set with the default values, and might be overridden in
|
|
some special cases. For example, some cases require more times
|
|
of "readinessProbe" failure before the peer mariadb-server node is
|
|
recovered. Other cases, in which the regular readiness probe cannot
|
|
be performed because only one signle mariadb-server exists, have to
|
|
take use of "startupProbe" to ensure the WSREP status are ready.
|
|
For all these exceptional cases above, which are different from the
|
|
default mariadb cluster with 3 nodes, we have to export the probe
|
|
parameters and override the related probe pareameters.
