🌐 Web query:

"CD_DAEMON_IMAGE_PULL_SECRET_NAMES" k8s-dra-driver-gpu

💡 Result:

The parameter CD_DAEMON_IMAGE_PULL_SECRET_NAMES is a configuration setting used in the Kubernetes SIGs NVIDIA DRA (Dynamic Resource Allocation) driver to specify Kubernetes secrets required for pulling container images for the ComputeDomain (CD) daemon [1]. This parameter allows administrators to provide a list of image pull secrets that the CD daemon should use when pulling images from private registries [1]. It was introduced to ensure that the driver can authenticate with registries requiring secure access when deploying the necessary daemon components [1]. To use this configuration, you typically pass it during the installation or upgrade of the dra-driver-nvidia-gpu Helm chart [2][3]. You can verify the availability of this and other parameters for your specific version of the chart by running: helm show values nvidia/dra-driver-nvidia-gpu For further details on deploying the driver and configuring image pull secrets, refer to the official documentation and the values.yaml file provided in the Helm chart repository [2][3].

🌐 Web query:

site:github.com/NVIDIA/k8s-dra-driver-gpu CD_DAEMON_IMAGE_PULL_SECRET_NAMES

💡 Result:

The term CD_DAEMON_IMAGE_PULL_SECRET_NAMES does not appear as a standard, documented configuration parameter in the NVIDIA DRA Driver for GPUs project [1]. Technical analysis of the project's source code and configuration templates indicates that image pull secret management is typically handled through similarly named flags or environment variables, such as IMAGE_PULL_SECRETS, which is used to specify comma-separated names for pod templates [2]. It is common in this project for configuration to be managed via Helm chart values or specific environment variables defined in individual component binaries (such as the GPU kubelet plugin or compute-domain-daemon) [2][3][4][5]. If you are encountering CD_DAEMON_IMAGE_PULL_SECRET_NAMES, it may be a custom or deprecated environment variable name used in a specific deployment environment rather than an official part of the driver's public API [1]. To configure image pull secrets for components in the NVIDIA DRA driver, it is recommended to use the supported Helm chart values provided by the project's official installation documentation [6].

"CD_DAEMON_IMAGE_PULL_SECRET_NAMES" "k8s-dra-driver-gpu"

💡 Result:

The environment variable CD_DAEMON_IMAGE_PULL_SECRET_NAMES is used in the NVIDIA Dynamic Resource Allocation (DRA) driver for GPUs to specify the names of Kubernetes image pull secrets required to authenticate with private container registries when pulling the ComputeDomain (CD) daemon image [1]. This parameter ensures that the CD daemon, which is critical for managing GPU resources and communication in multi-node environments, can be successfully pulled if the image resides in a restricted or private registry [1]. It was introduced to allow administrators to pass these secret names to the daemon configuration, as reflected in the NVIDIA DRA driver development history [1]. In practice, if you are deploying the k8s-dra-driver-gpu, you should: 1. Create a Kubernetes Secret containing your registry credentials in the relevant namespace. 2. Provide the name of that secret via the CD_DAEMON_IMAGE_PULL_SECRET_NAMES variable in your configuration (e.g., in your Helm chart values or environment configuration) [1]. Note that the NVIDIA DRA driver is increasingly being integrated into the broader NVIDIA GPU Operator ecosystem, which may simplify secret management for component images in future deployments [2][3].

Update existing compute-domain DaemonSets when image pull secrets change.

compute-domain-controller correctly parses comma-separated CD_DAEMON_IMAGE_PULL_SECRET_NAMES values, and an omitted variable produces no imagePullSecrets. However, its Create path returns an existing DaemonSet without updating it. Existing compute-domain-daemon DaemonSets can retain removed secrets and miss new ones, which can cause image pulls to fail. Reconcile the DaemonSet pod template when DRADriver.Spec.ImagePullSecrets changes.
