maxprocs: CPU quota undefined

[ardan-bkennedy]

This has not always been the case and I have tried to trace the code, but I don't know enough.

The project in question is https://github.com/ardanlabs/service and I am using KIND.

It seems to me /proc/self/cgroup is missing from the list of SuperOptions. Not sure why this is now happening.

Any guidance to debug or understand this would be appreciated. I can walk someone to run the code.

More information. I have a shell inside the running container. Just not sure what I can do with this information.

Any updates on this, I as well am hitting this same issue

[ardan-bkennedy]

I have not received anything :(

[embano1]

IMHO you‘re hitting cgroupv2 behavior on your underlying Docker host (where kind is running). IIUC, should be fixed by #44

[ardan-bkennedy]

I just verified that #44 fixes the problem.

[ardan-bkennedy]

I just tried the new 1.5.0 tagged release which was expected to fix the quota for cgroups2. It's not working :(

CPU quota undefined

@abhinav any ideas?

This fork is working
"github.com/emadolsky/automaxprocs/maxprocs"

[abhinav]

Based on discussion in #44 and #49, this looks like it's done.
Thanks for testing @ardan-bkennedy!
