Evan Lezar 00f1d5a627 Only allow host-relative LDConfig paths This change only allows host-relative LDConfig paths. An allow-ldconfig-from-container feature flag is added to allow for this the default behaviour to be changed. Signed-off-by: Evan Lezar <elezar@nvidia.com>		2024-11-22 14:25:17 +01:00

Introduction

This repository contains tools that allow docker, containerd, or cri-o to be configured to use the NVIDIA Container Toolkit.

Note: These were copied from the container-config repository are being migrated to commands installed with the NVIDIA Container Toolkit.

These will be migrated into an upcoming nvidia-ctk CLI as required.

Docker

After building the docker binary, run:

docker setup \
    --runtime-name NAME \
        /run/nvidia/toolkit

Configure the nvidia-container-runtime as a docker runtime named NAME. If the --runtime-name flag is not specified, this runtime would be called nvidia.

Since --set-as-default is enabled by default, the specified runtime name will also be set as the default docker runtime. This can be disabled by explicityly specifying --set-as-default=false.

The following table describes the behaviour for different --runtime-name and --set-as-default flag combinations.

Flags	Installed Runtimes	Default Runtime
NONE SPECIFIED	`nvidia`	`nvidia`
`--runtime-name nvidia`	`nvidia`	`nvidia`
`--runtime-name NAME`	`NAME`	`NAME`
`--set-as-default`	`nvidia`	`nvidia`
`--set-as-default --runtime-name nvidia`	`nvidia`	`nvidia`
`--set-as-default --runtime-name NAME`	`NAME`	`NAME`
`--set-as-default=false`	`nvidia`	NOT SET
`--set-as-default=false --runtime-name NAME`	`NAME`	NOT SET
`--set-as-default=false --runtime-name nvidia`	`nvidia`	NOT SET

These combinations also hold for the environment variables that map to the command line flags: DOCKER_RUNTIME_NAME, DOCKER_SET_AS_DEFAULT.

Containerd

After running the containerd binary, run:

containerd setup \
    --runtime-class NAME \
        /run/nvidia/toolkit

Configure the nvidia-container-runtime as a runtime class named NAME. If the --runtime-class flag is not specified, this runtime would be called nvidia.

Adding the --set-as-default flag as follows:

containerd setup \
    --runtime-class NAME \
    --set-as-default \
        /run/nvidia/toolkit

will set the runtime class NAME (or nvidia if not specified) as the default runtime class.

The following table describes the behaviour for different --runtime-class and --set-as-default flag combinations.

Flags	Installed Runtime Classes	Default Runtime Class
NONE SPECIFIED	`nvidia`	NOT SET
`--runtime-class NAME`	`NAME`	NOT SET
`--runtime-class nvidia`	`nvidia`	NOT SET
`--set-as-default`	`nvidia`	`nvidia`
`--set-as-default --runtime-class NAME`	`NAME`	`NAME`
`--set-as-default --runtime-class nvidia`	`nvidia`	`nvidia`

These combinations also hold for the environment variables that map to the command line flags.
