Hi community, I am a huge fan of flyte plugins. Currently I am trying to run it on pyflyte remote. I use this example from here: https://docs.flyte.org/projects/cookbook/en/latest/auto_examples/databricks_plugin/databricks_job.html and the docker file from here

FROM python:3.9-slim-buster
USER root
WORKDIR /root
ENV PYTHONPATH /root
RUN apt-get update && apt-get install build-essential -y
RUN apt-get install git -y
RUN pip install -U git+<https://github.com/future-outlier/flytekit.git@master>
RUN pip install flytekitplugins-spark
RUN pip install marshmallow-enum

However, I face an error that I need to setup my java in my docker file on my flyte console

[3/3] currentAttempt done. Last Error: SYSTEM::Traceback (most recent call last):

Is this because I need to use the docker file for Databricks mentioned in here? https://docs.flyte.org/projects/cookbook/en/latest/auto_examples/databricks_plugin/index.html#how-to-build-your-dockerfile-for-spark-on-databricks But this doesn't look like a complete Docker file to use because I didn't install flytekit in the dockerfile Can anyone clarify the concepts to use the plugins in pyflyte remote ? Thanks a lot

yes, you should install java in the image. use this dockerfile instead

Thanks a lot , I will try it out today !
