Prefect Community

Hello everyone! Is the `EXTRA_PIP_PACKAGES` environment variable supposed to work with `KubernetesFlowRunner`?

Looks like it should work if you use the base Prefect image to build your image because it’s in the <https://github.com/PrefectHQ/prefect/blob/orion/scripts/entrypoint.sh|entrypoint>. KubernetesFlowRunner can take in an `env`

I think this syntax will work
```KubernetesFlowRunner(env={"EXTRA_PIP_PACKAGES": "my-extra-package1 my-extra-package2"})```

I use the following command but it doesn't work `KubernetesFlowRunner(image="prefecthq/prefect:2.0b2-python3.8", env={"EXTRA_PIP_PACKAGES": "pandas"})` . Could this behavior be caused by redefining the `entrypoint` in Kubernetes Job manifest somewhere in Prefect?

Are you saying you added an entrypoint? Or do you mean Prefect might be overriding it to deploy a Flow?

I'm not sure `EXTRA_PIP_PACKAGES` works with KubernetesFlowRunner. I'm sure it works with <https://orion-docs.prefect.io/concepts/flow-runners/#adding-requirements-to-the-default-image|DockerFlowRunner> though.

<@U02H1A95XDW> yes, it works for me in `DockerFlowRunner` case :)

Actually this will take a while for me to try. Will get back to you tonight

ok, <@U02H1A95XDW> <@U01QEJ9PP53> thanks for the super fast response :)

<@U033R22H0F2> just tested it with `KubernetesFlowRunner` - `EXTRA_PIP_PACKAGES` doesn't work. So far you can only use `EXTRA_PIP_PACKAGES` with the `DockerFlowRunner` it seems. Let me open an issue to check if we can add it to `KubernetesFlowRunner` as well.

<@ULVA73B9P> open "Orion: allow to install EXTRA_PIP_PACKAGES at runtime using KubernetesFlowRunner"
