Evan Lezar 35df24d63a Make handling of nvidia-ctk path consistent 
This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.

Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.

Testing Packaging Workflows

Building the Docker images:

make images

This assumes that the nvidia-docker workflow is being tested and that the test packages have been published to the elezar.github.io GitHub pages page. These can be overridden using make variables.

Valid values for workflow are:

  • nvidia-docker
  • nvidia-container-runtime

This follows the instructions for setting up the nvidia-docker repostitory.

Testing local package changes

Running:

make local-ubuntu18.04

will build the ubuntu18.04-amd64 packages for release and launch a docker container with these packages added to a local APT repository.

The various apt workflows can then be tested as if the packages were released to the libnvidia-container experimental repository.

The local-centos8 make target is available for testing the centos8-x86_64 workflows as representative of yum-based installation workflows.

Example

In the centos8-based container above we see the following nvidia-docker2 packages available with the local-repository disabled:

$ yum list --showduplicates nvidia-docker2 | tail -2
nvidia-docker2.noarch           2.5.0-1                            nvidia-docker
nvidia-docker2.noarch           2.6.0-1                            nvidia-docker

Installing nvidia-docker2 shows:

$ yum install -y nvidia-docker2

installs the following packages:

$ yum list installed | grep nvidia
libnvidia-container-tools.x86_64   1.5.1-1                                 @libnvidia-container
libnvidia-container1.x86_64        1.5.1-1                                 @libnvidia-container
nvidia-container-runtime.x86_64    3.5.0-1                                 @nvidia-container-runtime
nvidia-container-toolkit.x86_64    1.5.1-2                                 @nvidia-container-runtime
nvidia-docker2.noarch              2.6.0-1                                 @nvidia-docker

Note the repositories where these packages were installed from.

We now enable the local-repository to simulate the new packages being published to the libnvidia-container experimental repository and check the available nvidia-docker2 versions:

$ yum-config-manager --enable local-repository
$ yum list --showduplicates nvidia-docker2 | tail -2
nvidia-docker2.noarch         2.6.0-1                           nvidia-docker
nvidia-docker2.noarch         2.6.1-0.1.rc.1                    local-repository

Showing the new version available in the local repository.

Running:

$ yum install nvidia-docker2

Upgrade  4 Packages

Total size: 1.7 M

Showing that all the components of the stack will be updated with versions from the local-repository.

After installation the installed packages are shown as:

$ yum list installed | grep nvidia
libnvidia-container-tools.x86_64   1.6.0-0.1.rc.1                          @local-repository

nvidia-docker2.noarch              2.6.1-0.1.rc.1                          @local-repository

Showing that:

  1. All versions have been installed from the same repository
  2. The nvidia-container-runtime package was removed as it is no longer required.

The nvidia-container-runtime executable is, however, still present on the system:

# ls -l /usr/bin/nvidia-container-runtime
-rwxr-xr-x 1 root root 2256280 Sep 24 12:42 /usr/bin/nvidia-container-runtime
