 # NVIDIA Container Toolkit Changelog
 
+## v1.16.0
+- Promote v1.16.0-rc.2 to v1.16.0
+
+### Changes in the Toolkit Container
+- Bump CUDA base image version to 12.5.1
+
+
+## v1.16.0-rc.2
+- Use relative path to locate driver libraries
+- Add RelativeToRoot function to Driver
+- Inject additional libraries for full X11 functionality
+- Extract options from default runtime if runc does not exist
+- Avoid using map pointers as maps are always passed by reference
+- Reduce logging for the NVIDIA Container runtime
+- Fix bug in argument parsing for logger creation
+
+## v1.16.0-rc.1
+
+- Support vulkan ICD files directly in a driver root. This allows for the discovery of vulkan files in GKE driver installations.
+- Increase priority of ld.so.conf.d config file injected into container. This ensures that injected libraries are preferred over libraries present in the container.
+- Set default CDI spec permissions to 644. This fixes permission issues when using the `nvidia-ctk cdi transform` functions.
+- Add `dev-root` option to `nvidia-ctk system create-device-nodes` command.
+- Fix location of `libnvidia-ml.so.1` when a non-standard driver root is used. This enabled CDI spec generation when using the driver container on a host.
+- Recalculate minimum required CDI spec version on save.
+- Move `nvidia-ctk hook` commands to a separate `nvidia-cdi-hook` binary. The same subcommands are supported.
+- Use `:` as an `nvidia-ctk config --set` list separator. This fixes a bug when trying to set config options that are lists.
+
+- [toolkit-container] Bump CUDA base image version to 12.5.0
+- [toolkit-container] Allow the path to `toolkit.pid` to be specified directly.
+- [toolkit-container] Remove provenance information from image manifests.
+- [toolkit-container] Add `dev-root` option when configuring the toolkit. This adds support for GKE driver installations.
+
+## v1.15.0
+
+* Remove `nvidia-container-runtime` and `nvidia-docker2` packages.
+* Use `XDG_DATA_DIRS` environment variable when locating config files such as graphics config files.
+* Add support for v0.7.0 Container Device Interface (CDI) specification.
+* Add `--config-search-path` option to `nvidia-ctk cdi generate` command. These paths are used when locating driver files such as graphics config files.

+# Release Process
+
+The NVIDIA Container Toolkit consists of the following artifacts:
+- The NVIDIA Container Toolkit container
+- Packages for debian-based systems
+- Packages for rpm-based systems
+
+# Release Process Checklist:
+- [ ] Create a release PR:
+    - [ ] Run the `./hack/prepare-release.sh` script to update the version in all the needed files. This also creates a [release issue](https://github.com/NVIDIA/cloud-native-team/issues?q=is%3Aissue+is%3Aopen+label%3Arelease)
+    - [ ] Run the `./hack/generate-changelog.sh` script to generate the a draft changelog and update `CHANGELOG.md` with the changes.
+    - [ ] Create a PR from the created `bump-release-{{ .VERSION }}` branch.
+- [ ] Merge the release PR
+- [ ] Tag the release and push the tag to the `internal` mirror:
+    - [ ] Image release pipeline: https://gitlab-master.nvidia.com/dl/container-dev/container-toolkit/-/pipelines/16466098
+- [ ] Wait for the image release to complete.
+- [ ] Push the tag to the the upstream GitHub repo.
+- [ ] Wait for the [`Release`](https://github.com/NVIDIA/k8s-device-plugin/actions/workflows/release.yaml) GitHub Action to complete
+- [ ] Publish the [draft release](https://github.com/NVIDIA/k8s-device-plugin/releases) created by the GitHub Action
+- [ ] Publish the packages to the gh-pages branch of the libnvidia-container repo
+- [ ] Create a KitPick
+
+## Troubleshooting
+
+*Note*: This assumes that we have the release tag checked out locally.
+
+- If the `Release` GitHub Action fails:
+    - Check the logs for the error first.
+    - Create the helm packages locally by running:
+      ```bash
+      ./hack/prepare-artifacts.sh {{ .VERSION }}
+      ```
+    - Create the draft release by running:
+      ```bash
+      ./hack/create-release.sh {{ .VERSION }}
+      ```

+# NVIDIA CDI Hook
+
+The CLI `nvidia-cdi-hook` provides container device runtime hook capabilities when
+called by a container runtime, as specific in a
+[Container Device Interface](https://tags.cncf.io/container-device-interface/blob/main/SPEC.md)
+file.
+
+## Generating a CDI
+
+The CDI itself is created for an NVIDIA-capable device using the
+[`nvidia-ctk cdi generate`](../nvidia-ctk/) command.
+
+When `nvidia-ctk cdi generate` is run, the CDI specification is generated as a yaml file.
+The CDI specification provides instructions for a container runtime to set up devices, files and
+other resources for the container prior to starting it. Those instructions
+may include executing command-line tools to prepare the filesystem. The execution
+of such command-line tools is called a hook.
+
+`nvidia-cdi-hook` is the CLI tool that is expected to be called by the container runtime,
+when specified by the CDI file.
+
+See the [`nvidia-ctk` documentation](../nvidia-ctk/README.md) for more information
+on generating a CDI file.
+
+## Functionality
+
+The `nvidia-cdi-hook` CLI provides the following functionality:
+
+* `chmod` - Change the permissions of a file or directory inside the directory path to be mounted into a container.
+* `create-symlinks` - Create symlinks inside the directory path to be mounted into a container.
+* `update-ldcache` - Update the dynamic linker cache inside the directory path to be mounted into a container.

+
+## Environment variables (OCI spec)
+
+Each environment variable maps to an command-line argument for `nvidia-container-cli` from [libnvidia-container](https://github.com/NVIDIA/libnvidia-container).
+These variables are already set in our [official CUDA images](https://hub.docker.com/r/nvidia/cuda/).
+
+### `NVIDIA_VISIBLE_DEVICES`
+This variable controls which GPUs will be made accessible inside the container.
+
+#### Possible values
+* `0,1,2`, `GPU-fef8089b` …: a comma-separated list of GPU UUID(s) or index(es).
+* `all`: all GPUs will be accessible, this is the default value in our container images.
+* `none`: no GPU will be accessible, but driver capabilities will be enabled.
+* `void` or *empty* or *unset*: `nvidia-container-runtime` will have the same behavior as `runc`.
+
+**Note**: When running on a MIG capable device, the following values will also be available:
+* `0:0,0:1,1:0`, `MIG-GPU-fef8089b/0/1` …: a comma-separated list of MIG Device UUID(s) or index(es).
+
+Where the MIG device indices have the form `<GPU Device Index>:<MIG Device Index>` as seen in the example output:
+```
+$ nvidia-smi -L
+GPU 0: Graphics Device (UUID: GPU-b8ea3855-276c-c9cb-b366-c6fa655957c5)
+  MIG Device 0: (UUID: MIG-GPU-b8ea3855-276c-c9cb-b366-c6fa655957c5/1/0)
+  MIG Device 1: (UUID: MIG-GPU-b8ea3855-276c-c9cb-b366-c6fa655957c5/1/1)
+  MIG Device 2: (UUID: MIG-GPU-b8ea3855-276c-c9cb-b366-c6fa655957c5/11/0)
+```
+
+### `NVIDIA_MIG_CONFIG_DEVICES`
+This variable controls which of the visible GPUs can have their MIG
+configuration managed from within the container. This includes enabling and
+disabling MIG mode, creating and destroying GPU Instances and Compute
+Instances, etc.
+
+#### Possible values
+* `all`: Allow all MIG-capable GPUs in the visible device list to have their
+  MIG configurations managed.
+
+**Note**:
+* This feature is only available on MIG capable devices (e.g. the A100).
+* To use this feature, the container must be started with `CAP_SYS_ADMIN` privileges.
+* When not running as `root`, the container user must have read access to the
+  `/proc/driver/nvidia/capabilities/mig/config` file on the host.
+
+### `NVIDIA_MIG_MONITOR_DEVICES`
+This variable controls which of the visible GPUs can have aggregate information
+about all of their MIG devices monitored from within the container. This
+includes inspecting the aggregate memory usage, listing the aggregate running
+processes, etc.
+
+#### Possible values
+* `all`: Allow all MIG-capable GPUs in the visible device list to have their
+  MIG devices monitored.
+
+**Note**:
+* This feature is only available on MIG capable devices (e.g. the A100).
+* To use this feature, the container must be started with `CAP_SYS_ADMIN` privileges.
+* When not running as `root`, the container user must have read access to the
+  `/proc/driver/nvidia/capabilities/mig/monitor` file on the host.
+
+### `NVIDIA_DRIVER_CAPABILITIES`
+This option controls which driver libraries/binaries will be mounted inside the container.
+
+#### Possible values
+* `compute,video`, `graphics,utility` …: a comma-separated list of driver features the container needs.
+* `all`: enable all available driver capabilities.
+* *empty* or *unset*: use default driver capability: `utility,compute`.
+
+#### Supported driver capabilities
+* `compute`: required for CUDA and OpenCL applications.
+* `compat32`: required for running 32-bit applications.
+* `graphics`: required for running OpenGL and Vulkan applications.
+* `utility`: required for using `nvidia-smi` and NVML.
+* `video`: required for using the Video Codec SDK.
+* `display`: required for leveraging X11 display.
+
+### `NVIDIA_REQUIRE_*`
+A logical expression to define constraints on the configurations supported by the container.
+
+#### Supported constraints
+* `cuda`: constraint on the CUDA driver version.
+* `driver`: constraint on the driver version.
+* `arch`: constraint on the compute architectures of the selected GPUs.
+* `brand`: constraint on the brand of the selected GPUs (e.g. GeForce, Tesla, GRID).
+
+#### Expressions
+Multiple constraints can be expressed in a single environment variable: space-separated constraints are ORed, comma-separated constraints are ANDed.
+Multiple environment variables of the form `NVIDIA_REQUIRE_*` are ANDed together.
+
+### `NVIDIA_DISABLE_REQUIRE`
+Single switch to disable all the constraints of the form `NVIDIA_REQUIRE_*`.
+
+### `NVIDIA_REQUIRE_CUDA`
+
+The version of the CUDA toolkit used by the container. It is an instance of the generic `NVIDIA_REQUIRE_*` case and it is set by official CUDA images.
+If the version of the NVIDIA driver is insufficient to run this version of CUDA, the container will not be started.
+
+#### Possible values
+* `cuda>=7.5`, `cuda>=8.0`, `cuda>=9.0` …: any valid CUDA version in the form `major.minor`.
+
+### `CUDA_VERSION`
+Similar to `NVIDIA_REQUIRE_CUDA`, for legacy CUDA images.
+In addition, if `NVIDIA_REQUIRE_CUDA` is not set, `NVIDIA_VISIBLE_DEVICES` and `NVIDIA_DRIVER_CAPABILITIES` will default to `all`.
+
+## Usage example
+
+**NOTE:** The use of the `nvidia-container-runtime` as CLI replacement for `runc` is uncommon and is only provided for completeness.
+
+Although the `nvidia-container-runtime` is typically configured as a replacement for `runc` or `crun` in various container engines, it can also be
+invoked from the command line as `runc` would. For example:
+
+```sh
+# Setup a rootfs based on Ubuntu 16.04
+cd $(mktemp -d) && mkdir rootfs
+curl -sS http://cdimage.ubuntu.com/ubuntu-base/releases/16.04/release/ubuntu-base-16.04.6-base-amd64.tar.gz | tar --exclude 'dev/*' -C rootfs -xz
+
+# Create an OCI runtime spec
+nvidia-container-runtime spec
+sed -i 's;"sh";"nvidia-smi";' config.json
+sed -i 's;\("TERM=xterm"\);\1, "NVIDIA_VISIBLE_DEVICES=0";' config.json
+
+# Run the container
+sudo nvidia-container-runtime run nvidia_smi
+```

 # NVIDIA Container Toolkit CLI
 
 The NVIDIA Container Toolkit CLI `nvidia-ctk` provides a number of utilities that are useful for working with the NVIDIA Container Toolkit.
+
+## Functionality
+
+### Configure runtimes
+
+The `runtime` command of the `nvidia-ctk` CLI provides a set of utilities to related to the configuration
+and management of supported container engines.
+
+For example, running the following command:
+```bash
+nvidia-ctk runtime configure --set-as-default
+```
+will ensure that the NVIDIA Container Runtime is added as the default runtime to the default container
+engine.
+
+## Configure the NVIDIA Container Toolkit
+
+The `config` command of the `nvidia-ctk` CLI allows a user to display and manipulate the NVIDIA Container Toolkit
+configuration.
+
+For example, running the following command:
+```bash
+nvidia-ctk config default
+```
+will display the default config for the detected platform.
+
+Whereas
+```bash
+nvidia-ctk config
+```
+will display the effective NVIDIA Container Toolkit config using the configured config file, and running:
+
+Individual config options can be set by specifying these are key-value pairs to the `--set` argument:
+
+```bash
+nvidia-ctk config --set nvidia-container-cli.no-cgroups=true
+```
+
+By default, all commands output to `STDOUT`, but specifying the `--output` flag writes the config to the specified file.
+
+### Generate CDI specifications
+
+The [Container Device Interface (CDI)](https://tags.cncf.io/container-device-interface) provides
+a vendor-agnostic mechanism to make arbitrary devices accessible in containerized environments. To allow NVIDIA devices to be
+used in these environments, the NVIDIA Container Toolkit CLI includes functionality to generate a CDI specification for the
+available NVIDIA GPUs in a system.
+
+In order to generate the CDI specification for the available devices, run the following command:\
+```bash
+nvidia-ctk cdi generate
+```
+
+The default is to print the specification to STDOUT and a filename can be specified using the `--output` flag.
+
+The specification will contain a device entries as follows (where applicable):
+* An `nvidia.com/gpu=gpu{INDEX}` device for each non-MIG-enabled full GPU in the system
+* An `nvidia.com/gpu=mig{GPU_INDEX}:{MIG_INDEX}` device for each MIG-device in the system
+* A special device called `nvidia.com/gpu=all` which represents all available devices.
+
+For example, to generate the CDI specification in the default location where CDI-enabled tools such as `podman`, `containerd`, `cri-o`, or the NVIDIA Container Runtime can be configured to load it, the following command can be run:
+
+```bash
+sudo nvidia-ctk cdi generate --output=/etc/cdi/nvidia.yaml
+```
+(Note that `sudo` is used to ensure the correct permissions to write to the `/etc/cdi` folder)
+
+With the specification generated, a GPU can be requested by specifying the fully-qualified CDI device name. With `podman` as an exmaple:
+```bash
+podman run --rm -ti --device=nvidia.com/gpu=gpu0 ubuntu nvidia-smi -L
+```
