QUESTION
I am trying to deploy a webserver with dramatiq and RabbitMQ and it seems like RabbitMQ is failing to start in Cloud Run.
The error messages I see are:
Uncaught signal: 10, pid=418, tid=418, fault_addr=0.
and many instances of:
Container Sandbox: Unsupported syscall getsockopt(0x44,0x1,0xc,0x3e18e39fc540,0x3e18e39fc548,0x0).
I used 4GB of memory, so I think it should be enough. Also important: the container does run locally. Any ideas?
...ANSWER
Answered 2021-Mar-28 at 19:06Your container runs in a sandox (GVisor) and it prevents some dangerous or abnormal system calls or CPU instructions. Try to change the RabbitMQ client to check if it's better.
In addition of this answer, I have 2 remarks:
- Keep in mind that Cloud Run can't run in background connexion to RabbitMQ and consume the messages. The CPU is allowed to your instance is processing a request; when not, the CPU is throttle (about 5% of the CPU power). I'm not sure that Cloud Run is the best platform to use Rabbit MQ (if you need to be always connected)
- A new sandbox is in the pipe. I don't know if it will solve your issue or not. Stay tuned.
QUESTION
I'm using dramatiq for my task queue which offers the decorator @dramatiq.actor
to decorate a function as a task. I've tried to write my own decorator that wraps the @dramatiq.actor
decorator so I can add a default argument to the @dramatiq.actor
decorator that applies to all tasks (The argument I'm talking about is priority=100
).
For some reason I'm getting the following error:
...ANSWER
Answered 2020-Jan-29 at 19:50Another approach would be to subclass the Dramatiq
class and override the actor
method. That approach plus some other tips described here - https://blog.narrativ.com/converting-celery-to-dramatiq-a-py3-war-story-23df217b426
