Python Application not running in kubernetes pod with readonlyrootfilesystem

I am trying to deploy my application is a kubernetes cluster where readonlyrootfilesystem is enabled. My application is getting deployed properly but when apache server tries to execute python3.6. It throws the following error continuously:

Current thread 0x00007f568a43ebc0 (most recent call first):

Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

I read about this error, but couldn't find any solution yet. I am attaching my manifest files for reference
