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 powerful one allows also to wait for pod names with this
(has to start with the given pod name):
wait_for:
name: myname
pods:
- test-pod
the powerful one allows also to wait for a service to be
available, which means all pods are deployed, which are
selected by the service definition:
wait_for:
name: myservice
services:
- mariadb-galera-service
the powerful one allows also to wait for pods with the
given "app" label:
wait_for:
name: myname
apps:
- mariadb-galera
the powerful one allows also to wait for jobs with this:
wait_for:
name: myname
jobs:
- '{{ include "common.release" . }}-the-job'
Be careful, as on the example above, the job name may have a "non fixed" name
and thus don't forget to use templates if needed
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 service / containers / pods /apps / 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 ) }}
