Database connection failed

[ssaravana21]

Thanks for the tutorial..

I am following this in kubesphere Env (kubernetes) at last I cannot access the moodle home page

Error: Database connection failed
It is possible that the database is overloaded or otherwise not running properly.
The site administrator should also check that the database details have been correctly specified in config.php
Moodle pod is running but showing following error
moodle (1).log

As checked I am using the same config as mentioned here (even password)

Any guidence...
Thank you in advance
