Can set cpu limit and memory limit?

[zcl0621]

I used daphne to run django channels in kubernetes pod. django running by uwsgi.

django == 2.2.7
daphne == 2.4.0
channels ==2.2.0
[uwsgi] chdir = /project module = backend.wsgi:application master = True processes = 1 http = 0.0.0.0:8000 vacuum = True max-requests = 2000 enable-threads = True thunder-lock = True limit-as = 256 asyncio = 200 attach-daemon = celery -A backend beat -l info attach-daemon = celery -A backend worker -l info --autoscale=15,10 -E attach-daemon = daphne -b 127.0.0.1 -p 8001 backend.asgi:application
I set pod 1 core and 1G memory.

If the pod run on 8 core 8G host. The pod running good.
But if the pod run on 32 core 64G host. The daphne will memory error.

The daphne will for too many process and used too many memory.Then kill by uwsgi.

So done daphne can set cpu limit and memory limit or ready set by cgroup?

thanks!

This is something you'd do with Systemd or Docker or …
