👍 Can we support Compose as well? https://github.com/compose-spec/compose-spec/blob/master/deploy.md#devices Can be another PR. |

Can we have ./docs/gpu.md to explain all the options?
We should also clarify how to set up GPU for rootless. (Can be another PR)

Added compose support and docs. |

ubuntu:20.04 -> nvidia/cuda:9.0-base might be more useful?
| - NVIDIA Drivers | ||
| - Same requirement as when you use GPUs on Docker. For details, please refer to [the doc by NVIDIA](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html#pre-requisites). | ||
| - `nvidia-container-cli` | ||
| - containerd relies on this CLI for setting up GPUs inside container. You can install this via [`libnvidia-container` package](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/arch-overview.html#libnvidia-container). |

Did you try rootless (on cgroup v1)?
I guess it needs setting no-cgroups = true

It doesn't work as of now.
We might need to patch github.com/containerd/containerd/contrib/nvidia for allowing to pass --no-cgroup option to nvidia-container-cli.
Containerd doesn't use nvidia-container-runtime (instead, it executes nvidia-container-cli directly) so we cannot use /etc/nvidia-container-runtime/config.toml for nerdctl.

A very hacky workaround for this is to wrap nvidia-container-cli to forcefully specify --no-cgroups.
mkdir -p /opt/nvidia/bin
mv /usr/bin/nvidia-container-cli /opt/nvidia/bin/
cat <<'EOF' > /usr/bin/nvidia-container-cli
#!/bin/bash
/opt/nvidia/bin/nvidia-container-cli ${@:1:($#-1)} --no-cgroups ${@:$#}
EOF

@AkihiroSuda containerd/containerd#5604 is merged.
Updated this PR to use --no-cgroup and now it works in rootless environment as well (without any additional configurations to /etc/nvidia-container-runtime/config.toml, etc.).
replace directive is needed in go.mod to forcefully point to the latest commit of containerd.

I'll release nedctl v0.9.0 after merging this. |

count and device_ids are mutually exclusive. we should define one field at a time. is it configured somewhere ?

@AkihiroSuda I will clear this ticket tonight #239 . It will be good to have it in 0.9 :) |

Without replace, go mod tidy wants to point to v1.5.2.
