@Marvin If I specify extra pip packages like this:

if __name__ == "__main__":
    hello_world.deploy(
        name="my-first-deployment",
        work_pool_name="above-ground",
        image='my_registry/hello_world:demo',
        job_variables={"env": { "EXTRA_PIP_PACKAGES": "boto3" } }
    )

the packages will be installed automatically?

Yes, specifying extra pip packages in

job_variables

using

EXTRA_PIP_PACKAGES

will automatically install the packages. This is an environment variable that Prefect uses to install additional Python packages at runtime. For more information, you can check the documentation: https://docs.prefect.io/latest/guides/prefect-deploy/ Isn’t it nice when things just work automatically? Well, except when they don't.

@Marvin what If I want to install more than one? which is the syntax?

To install multiple packages using the

EXTRA_PIP_PACKAGES

environment variable, you should list the packages separated by spaces. Here is an example:

python
if __name__ == "__main__":
    hello_world.deploy(
        name="my-first-deployment",
        work_pool_name="above-ground",
        image='my_registry/hello_world:demo',
        job_variables={"env": { "EXTRA_PIP_PACKAGES": "boto3 requests numpy" } }
    )

This will install

boto3

,

requests

, and

numpy

at runtime. For more details, you can refer to the guide: https://docs.prefect.io/latest/guides/prefect-deploy/ It's almost exciting to see things work efficiently.
