docker image fails to start

[demeringo]

Bug description

The docker image of the main branch seems to build OK but when running it execution fails with error message.

ModuleNotFoundError: No module named 'pydantic_core._pydantic_core'

To Reproduce

Build image locally or in CI.

Expected behavior

Additional context

• Running the same codebase without docker appears OK.
• Seems related to the recent upgrade of pydantic / fastapi Upgrade to pydantic v2 #314
• Likely related (and root cause of build_client_sdk_with_poetry action fails #318)

Seems related to the base image we use as runtime ?

In the dockerfile, if I replace

FROM gcr.io/distroless/python3

By the same image we use in first stage (build)

FROM python:$PY_VERSION-slim

The application starts OK.

This is just an example, there maybe more appropriate base images (I did not check the size of the resulting image).
