Notes on deploying to Google Cloud Run

[wlhong-allo]

Figured that i might share how i got it worked to save some fellows hours.

I spent 2 days getting below errors running on Cloud Run:

"Initialize error: Timed out after 30000 ms while trying to connect to the browser! Only Chrome at revision r1045629 is guaranteed to work."
OR
"Timed out waiting for nested object"

It turned out its because of the CPU allocation mechanism on Cloud Run.

check this out:
https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md#running-puppeteer-on-google-cloud-run

You need to enable Google Cloud Run to always allocate dedicated CPU for you otherwise the process will exit as soon as a response is returned without waiting for the puppeteer event to come back.

As of current GCP web UI, goto your cloud run service > Edit & Deploy New Revision > under "Billing" section, select "Instance-based" instead of "Request-based"

Note that it impact your GCP cost because now there are CPU resources always dedicated for your service:

Hope it helps~
