This change adds an nvidia-container-runtime.runtimes config option. If this is unset no changes are made to the config and the default values are used. This allows this setting to be overridden in cases where this is required. One such example is crio where crun is set as the default runtime. Signed-off-by: Evan Lezar <elezar@nvidia.com> |

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
. A runtime named nvidia-experimental
will also be configured using the nvidia-container-runtime.experimental
OCI-compliant runtime shim.
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
.
Note: If --runtime-name
is specified as nvidia-experimental
explicitly, the nvidia-experimental
runtime will be configured as the default runtime, with the nvidia
runtime still configured and available for use.
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-experimental |
nvidia |
--runtime-name nvidia |
nvidia , nvidia-experimental |
nvidia |
--runtime-name NAME |
NAME , nvidia-experimental |
NAME |
--runtime-name nvidia-experimental |
nvidia , nvidia-experimental |
nvidia-experimental |
--set-as-default |
nvidia , nvidia-experimental |
nvidia |
--set-as-default --runtime-name nvidia |
nvidia , nvidia-experimental |
nvidia |
--set-as-default --runtime-name NAME |
NAME , nvidia-experimental |
NAME |
--set-as-default --runtime-name nvidia-experimental |
nvidia , nvidia-experimental |
nvidia-experimental |
--set-as-default=false |
nvidia , nvidia-experimental |
NOT SET |
--set-as-default=false --runtime-name NAME |
NAME , nvidia-experimental |
NOT SET |
--set-as-default=false --runtime-name nvidia |
nvidia , nvidia-experimental |
NOT SET |
--set-as-default=false --runtime-name nvidia-experimental |
nvidia , nvidia-experimental |
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
. A runtime class named nvidia-experimental
will also be configured using the nvidia-container-runtime.experimental
OCI-compliant runtime shim.
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.
Note: If --runtime-class
is specified as nvidia-experimental
explicitly and --set-as-default
is specified, the nvidia-experimental
runtime will be configured as the default runtime class, with the nvidia
runtime class still configured and available for use.
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 , nvidia-experimental |
NOT SET |
--runtime-class NAME |
NAME , nvidia-experimental |
NOT SET |
--runtime-class nvidia |
nvidia , nvidia-experimental |
NOT SET |
--runtime-class nvidia-experimental |
nvidia , nvidia-experimental |
NOT SET |
--set-as-default |
nvidia , nvidia-experimental |
nvidia |
--set-as-default --runtime-class NAME |
NAME , nvidia-experimental |
NAME |
--set-as-default --runtime-class nvidia |
nvidia , nvidia-experimental |
nvidia |
--set-as-default --runtime-class nvidia-experimental |
nvidia , nvidia-experimental |
nvidia-experimental |
These combinations also hold for the environment variables that map to the command line flags.
