 Posted: Fri Jan 19, 2024 11:21 pm Post subject: [SOLVED]How do I enable CONFIG_CGROUP_BPF when using OpenRC? |
 |
|
Hi all,
My docker environment stopped working and the error when running "docker compose up -d" is:
| Code: | | Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error setting cgroup config for procHooks process: bpf_prog_query(BPF_CGROUP_DEVICE) failed: function not implemented: unknown |
It seems I need to enable the CONFIG_CGROUP_BPF kernel config option, but this is only available if you're using Systemd. I'm using OpenRC. Here's the details for that config option:
| Code: | Symbol: CGROUP_BPF [=n]
│ Type : bool
│ Defined at init/Kconfig:1157
│ Prompt: Support for eBPF programs attached to cgroups
│ Depends on: CGROUPS [=y] && BPF_SYSCALL [=n]
│ Location:
│ -> General setup
│ (1) -> Control Group support (CGROUPS [=y])
│ -> Support for eBPF programs attached to cgroups (CGROUP_BPF [=n])
│ Selects: SOCK_CGROUP_DATA [=y]
│ Selected by [n]:
│ - GENTOO_LINUX_INIT_SYSTEMD [=n] && GENTOO_LINUX [=y] && GENTOO_LINUX_UDEV [=y] |
How do I enable this option when I'm using OpenRC? If I can't, then how do I run docker on OpenRC?

This has nothing to do with systemd. Look at the line:
| Quote: | | Depends on: CGROUPS [=y] && BPF_SYSCALL [=n] |
You have CGROUPS enabled. Good. But your are missing BPF_SYSCALL.
Enable it:
| Code: | General setup --->
BPF subsystem --->
[*] Enable bpf() system call |
Now you should be able to enable:
| Code: | General setup --->
-*- Control Group support --->
[*] Support for eBPF programs attached to cgroups |

Thank you very much! Your post is appreciated. I should read what the kernel config says more closely. I was worried I'd have to convert to systemd which would be an annoyance.
I now have the kernel option enabled and my docker containers are working again.
Thanks again! |
