Not able to execute efg.py script inside the conta

问题:

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.
