Question -- what about /run/nvidia/toolkit/config/99-nvidia.toml? The toolkit container creates the toolkit.pid file at /run/nvidia/toolkit/toolkit.pid

I have updated this to /run/nvidia/toolkit/config/99-nvidia.toml.

@tariq1890 and I discussed this offline. I have updated the host path to /etc/containerd/conf.d/99-nvidia.toml

Ack. Should RUNTIME_CONFIG, if defined, take precedence over CONTAINERD_CONFIG/CRIO_CONFIG?

I think the latter should have higher precedence as it is more specific than RUNTIME_CONFIG. If you're in agreement with this, can we resolve the TODO in this PR?

Sure. Let me update this...

Updated so we now read RUNTIME_CONFIG as well, with the more specific envvars, e.g. CONTAINERD_CONFIG / CRIO_CONFIG, taking precedence. I also added additional unit test cases for this.

Why can't we mount the parent dir of the top-level config and the drop-in config dir? It seems like a lot of the container-toolkit implementation details are spilling into this PR? Any way to minimise? |
We are mounting the parent dir for both config files. |
