Extend Instabase images

Infrastructure administrators can extend the capabilities of celery-app-tasks by using the Instabase container as a base, and then installing additional packages on top of it. The option to extend certified images exists for scenarios where you need additional Python packages to achieve specific custom functionality in user-defined functions (UDFs).

After building your extended container, push it to a repository of your choice, and deploy it in place of the Instabase-provided image.

To extend the capabilities of user-defined functions (UDFs):

FROM gcr.io/instabase-public/celery-app-tasks:{YOUR_RECENT_RELEASE}

# Package installations and changes must be performed as root.
USER root

# Install your list of packages here!
RUN pip install --user \
    pyfiglet==0.7.6

# For security, we do not run our services as root. Switch back to the ib-user UID.
USER 9999
