Someone got a guide to setup a Google Cloud run for Prefect, im completly new with Google Cloud Run
j
l
Okay i think I can reach my Clodu run instance. But Im not able to install additional pip library with my deploy :
Copy code
if __name__ == "__main__":
    flow.from_source(
    	source="<https://github.com/lxup/recomend-prefect.git>",
    	entrypoint="flows/tmdb_update.py:tmdb_update",
    ).deploy(
        name="tmdb_update",
        work_pool_name="worker",
        cron="0 9 * * *",
        job_variables={
            "env": {
                "EXTRA_PIP_PACKAGES": "supabase more_itertools psycopg2-binary",
            }
        }
    )
Im getting
ModuleNotFoundError: No module named 'more_itertools'
I’m gonna try de make my own image
Ive created my own image like this :
FROM prefecthq/prefect:latest
RUN pip install supabase more_itertools psycopg2-binary
But Im getting this error : Flow run infrastructure exited with non-zero status code: Task classic-sawfish-j4qs9-task0 failed with message: The container exited with an error. (Error Code: 1) This may be caused by attempting to run an image with a misspecified platform or architecture.
w
can you share what command you are using to build the image? the platform matters, there is a mention of it in the docs here
l
If I cant use the linux/amd64, which architecture im supposed to use 😅 ? There is my command to build the image :
Copy code
docker build -t europe-west9-docker.pkg.dev/prefect-cloud-run/prefect-cloud/prefect:lastest . 
docker push europe-west9-docker.pkg.dev/prefect-cloud-run/prefect-cloud/prefect:lastest
My Dockerfile is :
Copy code
# We're using the latest version of Prefect with Python 3.10
FROM prefecthq/prefect:2-latest

# Add our requirements.txt file to the image and install dependencies
COPY requirements.txt .
RUN pip install -r requirements.txt --trusted-host pypi.python.org --no-cache-dir
Requirements.txt contain my differente pip lib :
Copy code
supabase
more_itertools
psycopg2-binary
But my script is pretty heavy in term of power, so do Google Cloud Run gonna handle it ? Because right now im testing the Prefect Cloud Worker, and Im getting a memory rate limite :
Copy code
Flow run infrastructure exited with non-zero status code:
 Task flow-run-92c7e781-8b7a-4acf-951e-34c01625ef90-21b252ae51dcjhfqw-task0 failed with message: The configured memory limit was reached. (Error Code: 1)
w
im actually a little confused. Can you try specifically setting
--platform linux/amd64
while i ask some folks internally?
l
Google Cloud Run isnt supposed to fail when running images built with
linux/amd64
?
w
i am currently confused about that and trying to test it. I can update the docs if need be.
l
That weird because using the default prefect images with Google Cloud Run its working but my custom image isnt (I just add 3 pip install)
w
yeah im trying to figure this out as well. Can you try to build the image with
--platform linux/amd64
and see if that runs?
ahh sorry - google cloud run needs amd64, the docs specify ar*m* is not supported not am*d.* I’m pretty confident if you build with the platform command i linked above thats going to work.
l
Im sorry but when Im suppod to qdd the
--plateform
flag ? Like that ?
docker build -t <http://europe-west9-docker.pkg.dev/prefect-cloud-run/prefect-cloud/prefect:lastest|europe-west9-docker.pkg.dev/prefect-cloud-run/prefect-cloud/prefect:lastest> . --platform linux/amd64
w
yep!
(also it says lastest, I think you mean latest)
l
wait its working
Im gonna try all the script to see
Ive just pay a month in other VPS ahah (Contabo for testing with 8gb of ram mb)
🤣😭
Well the script inside Google Cloud Run crash also probably because is to heavy in term of power needs. im getting this error :
Copy code
Encountered exception during execution:
Traceback (most recent call last):
...
02:02:45 AM
prefect.flow_runs
ERROR
Finished in state Failed('Flow run encountered an exception. MissingResult: The result was not persisted and is no longer available.')
Well Ive buy one month VPS with 4vCPU and 8GbRAM from Contabo to test and its working
So I guess there was an RAM issue
But anyway thx a lot @Will Raphaelson 🙏
w
Nice, we’re making progress.

you can request higher resources from cloud run for your deployment when you deploy. stealing your deployment script here:
Copy code
if __name__ == "__main__":
    flow.from_source(
    	source="<https://github.com/lxup/recomend-prefect.git>",
    	entrypoint="flows/tmdb_update.py:tmdb_update",
    ).deploy(
        name="tmdb_update",
        work_pool_name="worker",
        cron="0 9 * * *",
        job_variables={
            "memory": "8G",
        }
    )

Ohh didnt know that ! But its hard to have an idea oof the pricing of GOogle Cloud Run because my Contabo VPS is only 5.6e / months so cant know if Google gonna be cheaper but I should try
k
there is a decent pricing table here that you can use to estimate cost based on your resource requests + the runtime of your jobs
