InitContainer run a Python command

Question

I need to run a pip install command in an initcontainer. I´m using the python:3.9-slim-buster image .

I created the following code, however I get the following error:

/usr/local/bin/python3: No module named pip install moduleexample

Code:

        spec:
          volumes:
          - name: agent-volume
            emptyDir: {}
          initContainers:
          - name: dd-apm-init
            image: python:3.9-slim-buster
            command: ["python3", "-m", "pip install moduleexample"]
            resources: {}
            volumeMounts:
            - name: agent-volume
              mountPath: /usr/local/lib/python3.9/site-packages
            terminationMessagePath: /dev/termination-log
            terminationMessagePolicy: File
            imagePullPolicy: IfNotPresent

Any suggestions?

Answer 1

Try splitting the whole command:

 ["python3", "-m", "pip", "install", "moduleexample"]

Answer 2

You have given the command in the wrong format. It should be something like this -

spec:
      volumes:
      - name: agent-volume
        emptyDir: {}
      initContainers:
      - name: dd-apm-init
        image: python:3.9-slim-buster
        command: ["python3", "-m", "pip", "install", "moduleexample"]
        resources: {}
        volumeMounts:
        - name: agent-volume
          mountPath: /usr/local/lib/python3.9/site-packages
        terminationMessagePath: /dev/termination-log
        terminationMessagePolicy: File
        imagePullPolicy: IfNotPresent

Hope this would resolve the issue for you!
