Generate readiness part for a pod
Will look by default to .Values.wait_for
There are two formats available.
The simple one (where wait_for is just list of containers):
wait_for:
- aaf-locate
- aaf-cm
- aaf-service
The powerful one (where wait_for is a map):
wait_for:
name: myname
containers:
- aaf-locate
- aaf-cm
- aaf-service
The function can takes below arguments (inside a dictionary):
- .dot : environment (.)
- .initRoot : the root dictionary of readinessCheck submodule
(default to .Values.readinessCheck)
- .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 ) }}
*/}}
{{- define "common.readinessCheck.waitFor" -}}
{{- $dot := default . .dot -}}
{{- $initRoot := default $dot.Values.readinessCheck .initRoot -}}
{{/* Our version of helm doesn't support deepCopy so we need this nasty trick */}}
