NVIDIA Container Toolkit Release Tooling

This repository allows for the components of the NVIDIA container stack to be built and released as the NVIDIA Container Toolkit from a single repository. The components:

  • libnvidia-container
  • nvidia-container-runtime
  • nvidia-docker are included as submodules in the third_party folder.

The nvidia-container-toolkit resides in this repo directly.

Building

In oder to build the packages, the following command is executed

./scripts/build-packages.sh TARGET

where TARGET is a make target that is valid for each of the sub-components.

These include:

  • ubuntu18.04-amd64
  • centos8-x86_64

If no TARGET is specified, all valid release targets are built.

The packages are generated in the dist folder.

Testing local changes

In oder to use the same build logic to be used to generate packages with local changes, the location of the individual components can be overridded using the: LIBNVIDIA_CONTAINER_ROOT, NVIDIA_CONTAINER_TOOLKIT_ROOT, NVIDIA_CONTAINER_RUNTIME_ROOT, and NVIDIA_DOCKER_ROOT environment variables.

Testing packages locally

The test/release folder contains documentation on how the installation of local or staged packages can be tested.

Releasing

In order to release packages required for a release, a utility script scripts/release-packages.sh is provided. This script can be executed as follows:

GPG_LOCAL_USER="GPG_USER" \
MASTER_KEY_PATH=/path/to/gpg-master.key \
SUB_KEY_PATH=/path/to/gpg-subkey.key \
    ./scripts/release-packages.sh REPO PACKAGE_REPO_ROOT [REFERENCE]

Where REPO is one of stable or experimental, PACKAGE_REPO_ROOT is the local path to the libnvidia-container repository checked out to the gh-pages branch, and REFERENCE is the git SHA that is to be released. If reference is not specified HEAD is assumed.

This scripts performs the following basic functions:

  • Pulls the package image defined by the REFERENCE git SHA from the staging registry,
  • Copies the required packages to the package repository at PACKAGE_REPO_ROOT/REPO,
  • Signs the packages using the specified GPG keys

While the last two are performed, commits are added to the package repository. These can be pushed to the relevant repository.
