I'm pretty new on Google Cloud, and I just wanted to deploy my first streamlit webapp. I'm on Windows in command line. I already did the Google Cloud "Hello World" Example, which worked without any error.
When I deploy the streamlit webapp, I got after 3-4 minutes waiting "Updating Server" the following error:
ERROR: (gcloud.app.deploy) Error Response: [9] Flex operation projects/XXXX/regions/us-central1/operations/f0c89d22-2d09-410d-bf99-fc49ad337800 error [FAILED_PRECONDITION]: An internal error occurred while processing task /app-engine-flex/flex_await_healthy/flex_await_healthy>2021-05-27T06:13:50.278Z10796.jc.0: 2021-05-27 06:15:32.787 An update to the [server] config option section was detected. To have these changes be reflected, please restart streamlit.
That's my app.yaml file:
service: default
runtime: custom
env: flex
manual_scaling:
instances: 1
resources:
cpu: 1
memory_gb: 0.5
disk_size_gb: 10
Posting my comment as an answer for better visibility and to summarize.
In this particular case, the error was caused by a mistake in the Dockerfile.
Here are some steps you can follow to fix or narrow down the error:
gcloud components update
command.gcloud app deploy app.yaml --verbosity=debug
to try getting more specified error.
