Not able to execute efg.py script inside the conta

Question

1) Trying to run efg.py script inside the container as an arg in the kubernetes deployment file.
2) Inside the container the file is present in /opt/abc/efg.py.
3) While running the deployment it is showing no such file or directory.
4) These are the container spec:

    spec: containers: 
       -name: abc
        image: <full path here to the registry and image>
        imagePullPolicy: Always
        env:
        - name: PYTHONPATH
          value: "/opt"
        args:
        - /bin/sh
        - -c
        - cd /opt/abc && python3.6 efg.py

logs:

python3.6 :cant open the file : efg.py [errorno] no such file or directory exists.

The location of efg.py in the container is /opt/abc/efg.py.

Requirements: 1) Need to run the efg.py.
2) egf.py requires a log directory and a file to be created inside /opt/abc/. Something like this /opt/abc/log/efg.log.

a) either add mkdir in Dockerfile ("which is not working")
b) add it in the args

Solution:

1) Make the directory during docker image build

2) For running a script , give entry point in docker build or give it inside the deployment file in container specs as command:

["/bin/bash"] args: [ "-c", "cd /opt/ && python3.6 efg.py" ]

In addition, if you need a env variable to be exported inside the pod you can give it inside the deployment file. There are other ways, but this worked for OP.
