pod goes in CrashLoopBackOff. not enough logs for troubleshooting

[sdputurn]

we deployed this app in multiple clusters. it working in most of the cluster except few where the pod is getting into CrashLoopBackOff.

when check the logs where we have issue, we just see 2 lines like below:
I0603 07:49:48.723928 1 secure_serving.go:116] Serving securely on [::]:443
time="2021-06-03T07:49:48Z" level=info msg="Using OpenStack Keystone at https://identity.xxxx.internal.cloud/v3/"

in all working cluster we are seeing logs like:
I0602 06:49:10.671035 1 secure_serving.go:116] Serving securely on [::]:443
time="2021-06-02T06:49:10Z" level=info msg="Using OpenStack Keystone at https://identity.xxxx.internal.cloud/v3/"
time="2021-06-02T06:49:10Z" level=info msg="Found OpenStack Designate service at https://dns.xxx.internal.cloud/"

is there the way to get debug level logs? not able to get for what reason the pod is not progressing in cluster having issues.

thanks,
Sandeep
