+ Generate readiness part for a pod
+ Will look by default to .Values.wait_for
+
+ Value of wait_for is an array of all pods /jobs to wait:
+
+ Example:
+
+ wait_for:
+ - aaf-locate
+ - aaf-cm
+ - aaf-service
+
+ The function can takes two arguments (inside a dictionary):
+ - .dot : environment (.)
+ - .wait_for : list of containers / jobs to wait for (default to
+ .Values.wait_for)
+
+ Example calls:
+ {{ include "common.readinessCheck.waitFor" . }}
+ {{ include "common.readinessCheck.waitFor" (dict "dot" . "wait_for" .Values.where.my.wait_for.is ) }}
