Unable to start the airflow component

[dhandma]

Hi Bhavani,
I have tried to setup the airflow using the script shared by you by building own docker image ( mayurdhande007/my-airflow-example:airflow_v1.1 as well as mayurdhande007/my-airflow-example:airflow_v1.2 ) and ran the deploy.sh as suggested by updating AIRFLOW_IMAGE and AIRFLOW_TAG values in deploy.sh.
After this, it spun up the postgres pod but failing to start the init container.
PFB events for pods:

I have uploaded the updated templates in github "https://github.com/dhandma/my-airflow-setup-k8s.git" for reference.
Any help would be appreciated.

Many Thanks ,
