Timeout of long function execution about faasd

[dsrowell]

I wanted to leave this in case someone else gets here attempting to use long function execution specifically with faasd (which I love). In addition to adding the *_timeout values to the /var/lib/faasd/docker-compose.yaml and the function's yaml file, I had to create the following file:

/etc/systemd/system/faasd-provider.service.d/override.conf

with the following contents:

[Service]
Environment="service_timeout=5m"

to bump the gateway's timeout to 5 minutes. I am happy to hear if there is a better/easier way (I only tested on ubuntu 20.04), but if not, I hope this helps others.

This might be a red herring since I may have been invoking without a POST method. Closing for the time being. We should look at changing the timeout to being dynamic though.

Reproduced accidentally...

Turned out that whatever I set timeout was hard set for 10sec. Changing read/write timeout alone did not help (as per OpenFaaS Troubleshooting) but adding the following to stack.yml, shamelessly taken from go-long example solved it :-)

    environment:
      write_timeout: 3m
      read_timeout: 3m
      exec_timeout: 3m
      handler_wait_duration: 60s

This issue doesn't apply anymore given the configuration with the compose file.

The timeouts need to "agree" between the function and the core services, there is a new tutorial for this: https://docs.openfaas.com/tutorials/expanded-timeouts/

I've modified the var/lib/faasd/docker-compose.yaml and also added docker-compose.yaml to my function's root folder. However the timeout is still hard-fixed and unable to see any change. I would really appreciate it if someone can provide a step-by-step guide to modify the timeout!

Hey @ikhyunAn this is all covered in the eBook. I'd suggest you buy a copy.
