TL;DR

The issue can be resolved by configuring the Prisma generate command to write to a writable directory instead of the read-only /usr/lib/python3.13/site-packages/prisma/ directory.

Guidance

• The error occurs because the Prisma generate command tries to write to a read-only directory. To fix this, you can configure the command to write to a writable directory, such as a mounted volume.
• You can modify the extraInitContainers section of the migration job to include a volume mount that allows the Prisma generate command to write to a writable directory.
• The readOnlyRootFilesystem security setting prevents writes to the root filesystem, so you will need to ensure that the writable directory is explicitly mounted as a volume.
• You can verify that the fix worked by checking the logs for the migration job and ensuring that the Prisma generate command is able to write to the specified directory without encountering a PermissionError.

Example

extraInitContainers:
  - name: stage-prisma
    image: ghcr.io/berriai/litellm-database:main-stable
    command: ["sh", "-c", "cp -a /usr/lib/python3.13/site-packages/prisma/. /staging/"]
    volumeMounts:
      - { name: prisma-pkg, mountPath: /staging }
      - { name: prisma-writable, mountPath: /writable }

In this example, a new volume mount is added to the extraInitContainers section, which allows the Prisma generate command to write to the /writable directory.

Notes

The exact configuration changes required may vary depending on the specific requirements of your application and the constraints of your environment.

Recommendation

Apply a workaround by configuring the Prisma generate command to write to a writable directory, such as a mounted volume. This will allow the command to complete successfully
