Field	Description	Default	Validation
`apiVersion` string	`nvidia.com/v1alpha1`
`kind` string	`DynamoGraphDeployment`
`metadata` ObjectMeta	Refer to Kubernetes API documentation for fields of `metadata`.
`spec` DynamoGraphDeploymentSpec	Spec defines the desired state for this graph deployment.
`status` DynamoGraphDeploymentStatus	Status reflects the current observed state of this graph deployment.

DynamoGraphDeploymentRequest

DynamoGraphDeploymentRequest is the Schema for the dynamographdeploymentrequests API. It serves as the primary interface for users to request model deployments with specific performance and resource constraints, enabling SLA-driven deployments.

Lifecycle:

Initializing → Pending: Validates spec and prepares for profiling
Pending → Profiling: Creates and runs profiling job (online or AIC)
Profiling → Ready/Deploying: Generates DGD spec after profiling completes
Deploying → Ready: When autoApply=true, monitors DGD until Ready
Ready: Terminal state when DGD is operational or spec is available
DeploymentDeleted: Terminal state when auto-created DGD is manually deleted

The spec becomes immutable once profiling starts. Users must delete and recreate the DGDR to modify configuration after this point.

DEPRECATION NOTICE: v1alpha1 DynamoGraphDeploymentRequest is deprecated. Please migrate to nvidia.com/v1beta1 DynamoGraphDeploymentRequest. v1alpha1 will be removed in a future release.

Field	Description	Default	Validation
`apiVersion` string	`nvidia.com/v1alpha1`

`metadata` ObjectMeta	Refer to Kubernetes API documentation for fields of `metadata`.
`spec` DynamoGraphDeploymentRequestSpec	Spec defines the desired state for this deployment request.
`status` DynamoGraphDeploymentRequestStatus	Status reflects the current observed state of this deployment request.

DynamoGraphDeploymentRequestSpec

DynamoGraphDeploymentRequestSpec defines the desired state of a DynamoGraphDeploymentRequest. This CRD serves as the primary interface for users to request model deployments with specific performance constraints and resource requirements, enabling SLA-driven deployments.

Appears in:

DynamoGraphDeploymentRequest

Field	Description	Default	Validation
`model` string	Model specifies the model to deploy (e.g., “Qwen/Qwen3-0.6B”, “meta-llama/Llama-3-70b”). This is a high-level identifier for easy reference in kubectl output and logs. The controller automatically sets this value in profilingConfig.config.deployment.model.		Required: {}
`backend` string	Backend specifies the inference backend for profiling. The controller automatically sets this value in profilingConfig.config.engine.backend. Profiling runs on real GPUs or via AIC simulation to collect performance data.		Enum: [auto vllm sglang trtllm] Required: {}
`useMocker` boolean	UseMocker indicates whether to deploy a mocker DynamoGraphDeployment instead of a real backend deployment. When true, the deployment uses simulated engines that don’t require GPUs, using the profiling data to simulate realistic timing behavior. Mocker is available in all backend images and useful for large-scale experiments. Profiling still runs against the real backend (specified above) to collect performance data.	false
`profilingConfig` ProfilingConfigSpec	ProfilingConfig provides the complete configuration for the profiling job. Note: GPU discovery is automatically attempted to detect GPU resources from Kubernetes cluster nodes. If the operator has node read permissions (cluster-wide or explicitly granted), discovered GPU configuration is used as defaults when hardware configuration is not manually specified (minNumGpusPerEngine, maxNumGpusPerEngine, numGpusPerNode). User-specified values always take precedence over auto-discovered values. If GPU discovery fails (e.g., namespace-restricted operator without node permissions), manual hardware config is required. This configuration is passed directly to the profiler. The structure matches the profile_sla config format exactly (see ProfilingConfigSpec for schema). Note: deployment.model and engine.backend are automatically set from the high-level modelName and backend fields and should not be specified in this config.		Required: {}
`enableGpuDiscovery` boolean	EnableGPUDiscovery controls whether the operator attempts to discover GPU hardware from cluster nodes. DEPRECATED: This field is deprecated and will be removed in v1beta1. GPU discovery is now always attempted automatically. Setting this field has no effect - the operator will always try to discover GPU hardware when node read permissions are available. If discovery is unavailable (e.g., namespace-scoped operator without permissions), manual hardware configuration is required regardless of this setting.	true	Optional: {}
`autoApply` boolean	AutoApply indicates whether to automatically create a DynamoGraphDeployment after profiling completes. If false, only the spec is generated and stored in status. Users can then manually create a DGD using the generated spec.	false
`deploymentOverrides` DeploymentOverridesSpec	DeploymentOverrides allows customizing metadata for the auto-created DGD. Only applicable when AutoApply is true.		Optional: {}

Operator Default Values Injection

The Dynamo operator automatically applies default values to various fields when they are not explicitly specified in your deployments. These defaults include:

Health Probes: Startup, liveness, and readiness probes are configured differently for frontend, worker, and planner components. For example, worker components receive a startup probe with a 2-hour timeout (720 failures × 10 seconds) to accommodate long model loading times.
Security Context: All components receive fsGroup: 1000 by default to ensure proper file permissions for mounted volumes. This can be overridden via the extraPodSpec.securityContext field.
Shared Memory: All components receive an 8Gi shared memory volume mounted at /dev/shm by default (can be disabled or resized via the sharedMemory field).
Environment Variables: Components automatically receive environment variables like DYN_NAMESPACE, DYN_PARENT_DGD_K8S_NAME, DYNAMO_PORT, and backend-specific variables.
Pod Configuration: Default terminationGracePeriodSeconds of 60 seconds and restartPolicy: Always.
Autoscaling: When enabled without explicit metrics, defaults to CPU-based autoscaling with 80% target utilization.
Backend-Specific Behavior: For multinode deployments, probes are automatically modified or removed for worker nodes depending on the backend framework (VLLM, SGLang, or TensorRT-LLM).

Pod Specification Defaults

All components receive the following pod-level defaults unless overridden:

terminationGracePeriodSeconds: 60 seconds
restartPolicy: Always

Security Context

The operator automatically applies default security context settings to all components to ensure proper file permissions, particularly for mounted volumes:

fsGroup: 1000 - Sets the group ownership of mounted volumes and any files created in those volumes

This default ensures that non-root containers can write to mounted volumes (like model caches or persistent storage) without permission issues. The fsGroup setting is particularly important for:

Model downloads and caching
Compilation cache directories
Persistent volume claims (PVCs)
SSH key generation in multinode deployments

Overriding Security Context

To override the default security context, specify your own securityContext in the extraPodSpec of your component:

1 services:
2   YourWorker:
3     extraPodSpec:
4       securityContext:
5         fsGroup: 2000  # Custom group ID
6         runAsUser: 1000
7         runAsGroup: 1000
8         runAsNonRoot: true

Important: When you provide any securityContext object in extraPodSpec, the operator will not inject any defaults. This gives you complete control over the security context, including the ability to run as root (by omitting runAsNonRoot or setting it to false).

OpenShift and Security Context Constraints

In OpenShift environments with Security Context Constraints (SCCs), you may need to omit explicit UID/GID values to allow OpenShift’s admission controllers to assign them dynamically:

1 services:
2   YourWorker:
3     extraPodSpec:
4       securityContext:
5         # Omit fsGroup to let OpenShift assign it based on SCC
6         # OpenShift will inject the appropriate UID range

Alternatively, if you want to keep the default fsGroup: 1000 behavior and are certain your cluster allows it, you don’t need to specify anything - the operator defaults will work.

Shared Memory Configuration

Shared memory is enabled by default for all components:

Enabled: true (unless explicitly disabled via sharedMemory.disabled)
Size: 8Gi
Mount Path: /dev/shm
Volume Type: emptyDir with memory medium

To disable shared memory or customize the size, use the sharedMemory field in your component specification.

Health Probes by Component Type

The operator applies different default health probes based on the component type.

Frontend Components

Frontend components receive the following probe configurations:

Liveness Probe:

Type: HTTP GET
Path: /health
Port: http (8000)
Initial Delay: 60 seconds
Period: 60 seconds
Timeout: 30 seconds
Failure Threshold: 10

Readiness Probe:

Type: Exec command
Command: curl -s http://localhost:${DYNAMO_PORT}/health | jq -e ".status == \"healthy\""
Initial Delay: 60 seconds
Period: 60 seconds
Timeout: 30 seconds
Failure Threshold: 10

Worker Components

Worker components receive the following probe configurations:

Liveness Probe:

Type: HTTP GET
Path: /live
Port: system (9090)
Period: 5 seconds
Timeout: 30 seconds
Failure Threshold: 1

Readiness Probe:

Type: HTTP GET
Path: /health
Port: system (9090)
Period: 10 seconds
Timeout: 30 seconds
Failure Threshold: 60

Startup Probe:

Type: HTTP GET
Path: /live
Port: system (9090)
Period: 10 seconds
Timeout: 5 seconds
Failure Threshold: 720 (allows up to 2 hours for startup: 10s × 720 = 7200s)

:::{note} For larger models (typically >70B parameters) or slower storage systems, you may need to increase the failureThreshold to allow more time for model loading. Calculate the required threshold based on your expected startup time: failureThreshold = (expected_startup_seconds / period). Override the startup probe in your component specification if the default 2-hour window is insufficient. :::

Multinode Deployment Probe Modifications

For multinode deployments, the operator modifies probes based on the backend framework and node role:

VLLM Backend

The operator automatically selects between two deployment modes based on parallelism configuration:

Tensor/Pipeline Parallel Mode (when world_size > GPUs_per_node):

Uses Ray for distributed execution (--distributed-executor-backend ray)
Leader nodes: Starts Ray head and runs vLLM; all probes remain active
Worker nodes: Run Ray agents only; all probes (liveness, readiness, startup) are removed

Data Parallel Mode (when world_size × data_parallel_size > GPUs_per_node):

Worker nodes: All probes (liveness, readiness, startup) are removed
Leader nodes: All probes remain active

SGLang Backend

Worker nodes: All probes (liveness, readiness, startup) are removed

TensorRT-LLM Backend

Leader nodes: All probes remain unchanged
Worker nodes:
- Liveness and startup probes are removed
- Readiness probe is replaced with a TCP socket check on SSH port (2222):
  - Initial Delay: 20 seconds
  - Period: 20 seconds
  - Timeout: 5 seconds
  - Failure Threshold: 10

Service Accounts

The following component types automatically receive dedicated service accounts:

Image Pull Secrets

The operator automatically discovers and injects image pull secrets for container images. When a component specifies a container image, the operator:

Scans all Kubernetes secrets of type kubernetes.io/dockerconfigjson in the component’s namespace
Extracts the docker registry server URLs from each secret’s authentication configuration
Matches the container image’s registry host against the discovered registry URLs
Automatically injects matching secrets as imagePullSecrets in the pod specification

This eliminates the need to manually specify image pull secrets for each component. The operator maintains an internal index of docker secrets and their associated registries, refreshing this index periodically.

To disable automatic image pull secret discovery for a specific component, add the following annotation:

1 annotations:
2   nvidia.com/disable-image-pull-secret-discovery: "true"

Autoscaling Defaults

When autoscaling is enabled but no metrics are specified, the operator applies:

Default Metric: CPU utilization
Target Average Utilization: 80%

Port Configurations

Default container ports are configured based on component type:

Frontend Components

Port: 8000
Protocol: TCP
Name: http

Worker Components

Port: 9090 (system)
Protocol: TCP
Name: system
Port: 19090 (NIXL)

Implementation Reference

For users who want to understand the implementation details or contribute to the operator, the default values described in this document are set in the following source files:

Health Probes, Security Context & Pod Specifications: internal/dynamo/graph.go - Contains the main logic for applying default probes, security context, environment variables, shared memory, and pod configurations
Component-Specific Defaults:
- internal/dynamo/component_common.go - Base container and pod spec shared by all component types
- internal/dynamo/component_frontend.go
- internal/dynamo/component_worker.go
- internal/dynamo/component_planner.go
- internal/dynamo/component_epp.go
Image Pull Secrets: internal/secrets/docker.go - Implements the docker secret indexer and automatic discovery
Backend-Specific Behavior:
Checkpoint / Restore: internal/checkpoint/dgd_integration.go - Checkpoint env var injection and volume setup
Constants & Annotations: internal/consts/consts.go - Defines annotation keys and other constants

Notes

All these defaults can be overridden by explicitly specifying values in your DynamoComponentDeployment or DynamoGraphDeployment resources
User-specified probes (via livenessProbe, readinessProbe, or startupProbe fields) take precedence over operator defaults
For security context, if you provide any securityContext in extraPodSpec, no defaults will be injected, giving you full control
For multinode deployments, some defaults are modified or removed as described above to accommodate distributed execution patterns
The extraPodSpec.mainContainer field can be used to override probe configurations set by the operator

DynamoGraphDeployment

DynamoGraphDeployment is the Schema for the dynamographdeployments API.

Field	Description	Default	Validation
`apiVersion` string	`nvidia.com/v1alpha1`
`kind` string	`DynamoGraphDeployment`
`metadata` ObjectMeta	Refer to Kubernetes API documentation for fields of `metadata`.
`spec` DynamoGraphDeploymentSpec	Spec defines the desired state for this graph deployment.
`status` DynamoGraphDeploymentStatus	Status reflects the current observed state of this graph deployment.

DynamoGraphDeploymentRequest

Lifecycle:

Initializing → Pending: Validates spec and prepares for profiling
Pending → Profiling: Creates and runs profiling job (online or AIC)
Profiling → Ready/Deploying: Generates DGD spec after profiling completes
Deploying → Ready: When autoApply=true, monitors DGD until Ready
Ready: Terminal state when DGD is operational or spec is available
DeploymentDeleted: Terminal state when auto-created DGD is manually deleted

The spec becomes immutable once profiling starts. Users must delete and recreate the DGDR to modify configuration after this point.

DEPRECATION NOTICE: v1alpha1 DynamoGraphDeploymentRequest is deprecated. Please migrate to nvidia.com/v1beta1 DynamoGraphDeploymentRequest. v1alpha1 will be removed in a future release.

DynamoGraphDeploymentRequestSpec

Appears in:

DynamoGraphDeploymentRequest

Field	Description	Default	Validation
`model` string	Model specifies the model to deploy (e.g., “Qwen/Qwen3-0.6B”, “meta-llama/Llama-3-70b”). This is a high-level identifier for easy reference in kubectl output and logs. The controller automatically sets this value in profilingConfig.config.deployment.model.		Required: {}
`backend` string	Backend specifies the inference backend for profiling. The controller automatically sets this value in profilingConfig.config.engine.backend. Profiling runs on real GPUs or via AIC simulation to collect performance data.		Enum: [auto vllm sglang trtllm] Required: {}
`useMocker` boolean	UseMocker indicates whether to deploy a mocker DynamoGraphDeployment instead of a real backend deployment. When true, the deployment uses simulated engines that don’t require GPUs, using the profiling data to simulate realistic timing behavior. Mocker is available in all backend images and useful for large-scale experiments. Profiling still runs against the real backend (specified above) to collect performance data.	false
`profilingConfig` ProfilingConfigSpec	ProfilingConfig provides the complete configuration for the profiling job. Note: GPU discovery is automatically attempted to detect GPU resources from Kubernetes cluster nodes. If the operator has node read permissions (cluster-wide or explicitly granted), discovered GPU configuration is used as defaults when hardware configuration is not manually specified (minNumGpusPerEngine, maxNumGpusPerEngine, numGpusPerNode). User-specified values always take precedence over auto-discovered values. If GPU discovery fails (e.g., namespace-restricted operator without node permissions), manual hardware config is required. This configuration is passed directly to the profiler. The structure matches the profile_sla config format exactly (see ProfilingConfigSpec for schema). Note: deployment.model and engine.backend are automatically set from the high-level modelName and backend fields and should not be specified in this config.		Required: {}
`enableGpuDiscovery` boolean	EnableGPUDiscovery controls whether the operator attempts to discover GPU hardware from cluster nodes. DEPRECATED: This field is deprecated and will be removed in v1beta1. GPU discovery is now always attempted automatically. Setting this field has no effect - the operator will always try to discover GPU hardware when node read permissions are available. If discovery is unavailable (e.g., namespace-scoped operator without permissions), manual hardware configuration is required regardless of this setting.	true	Optional: {}
`autoApply` boolean	AutoApply indicates whether to automatically create a DynamoGraphDeployment after profiling completes. If false, only the spec is generated and stored in status. Users can then manually create a DGD using the generated spec.	false

Operator Default Values Injection

The Dynamo operator automatically applies default values to various fields when they are not explicitly specified in your deployments. These defaults include:

Health Probes: Startup, liveness, and readiness probes are configured differently for frontend, worker, and planner components. For example, worker components receive a startup probe with a 2-hour timeout (720 failures × 10 seconds) to accommodate long model loading times.
Security Context: All components receive fsGroup: 1000 by default to ensure proper file permissions for mounted volumes. This can be overridden via the extraPodSpec.securityContext field.
Shared Memory: All components receive an 8Gi shared memory volume mounted at /dev/shm by default (can be disabled or resized via the sharedMemory field).
Environment Variables: Components automatically receive environment variables like DYN_NAMESPACE, DYN_PARENT_DGD_K8S_NAME, DYNAMO_PORT, and backend-specific variables.
Pod Configuration: Default terminationGracePeriodSeconds of 60 seconds and restartPolicy: Always.
Autoscaling: When enabled without explicit metrics, defaults to CPU-based autoscaling with 80% target utilization.
Backend-Specific Behavior: For multinode deployments, probes are automatically modified or removed for worker nodes depending on the backend framework (VLLM, SGLang, or TensorRT-LLM).

Pod Specification Defaults

All components receive the following pod-level defaults unless overridden:

terminationGracePeriodSeconds: 60 seconds
restartPolicy: Always

Security Context

The operator automatically applies default security context settings to all components to ensure proper file permissions, particularly for mounted volumes:

fsGroup: 1000 - Sets the group ownership of mounted volumes and any files created in those volumes

This default ensures that non-root containers can write to mounted volumes (like model caches or persistent storage) without permission issues. The fsGroup setting is particularly important for:

Model downloads and caching
Compilation cache directories
Persistent volume claims (PVCs)
SSH key generation in multinode deployments

Overriding Security Context

To override the default security context, specify your own securityContext in the extraPodSpec of your component:

1 services:
2   YourWorker:
3     extraPodSpec:
4       securityContext:
5         fsGroup: 2000  # Custom group ID
6         runAsUser: 1000
7         runAsGroup: 1000
8         runAsNonRoot: true

OpenShift and Security Context Constraints

In OpenShift environments with Security Context Constraints (SCCs), you may need to omit explicit UID/GID values to allow OpenShift’s admission controllers to assign them dynamically:

1 services:
2   YourWorker:
3     extraPodSpec:
4       securityContext:
5         # Omit fsGroup to let OpenShift assign it based on SCC
6         # OpenShift will inject the appropriate UID range

Alternatively, if you want to keep the default fsGroup: 1000 behavior and are certain your cluster allows it, you don’t need to specify anything - the operator defaults will work.

Shared Memory Configuration

Shared memory is enabled by default for all components:

Enabled: true (unless explicitly disabled via sharedMemory.disabled)
Size: 8Gi
Mount Path: /dev/shm
Volume Type: emptyDir with memory medium

To disable shared memory or customize the size, use the sharedMemory field in your component specification.

Health Probes by Component Type

The operator applies different default health probes based on the component type.

Frontend Components

Frontend components receive the following probe configurations:

Liveness Probe:

Type: HTTP GET
Path: /health
Port: http (8000)
Initial Delay: 60 seconds
Period: 60 seconds
Timeout: 30 seconds
Failure Threshold: 10

Readiness Probe:

Type: Exec command
Command: curl -s http://localhost:${DYNAMO_PORT}/health | jq -e ".status == \"healthy\""
Initial Delay: 60 seconds
Period: 60 seconds
Timeout: 30 seconds
Failure Threshold: 10

Worker Components

Worker components receive the following probe configurations:

Liveness Probe:

Type: HTTP GET
Path: /live
Port: system (9090)
Period: 5 seconds
Timeout: 30 seconds
Failure Threshold: 1

Readiness Probe:

Type: HTTP GET
Path: /health
Port: system (9090)
Period: 10 seconds
Timeout: 30 seconds
Failure Threshold: 60

Startup Probe:

Type: HTTP GET
Path: /live
Port: system (9090)
Period: 10 seconds
Timeout: 5 seconds
Failure Threshold: 720 (allows up to 2 hours for startup: 10s × 720 = 7200s)

Multinode Deployment Probe Modifications

For multinode deployments, the operator modifies probes based on the backend framework and node role:

VLLM Backend

The operator automatically selects between two deployment modes based on parallelism configuration:

Tensor/Pipeline Parallel Mode (when world_size > GPUs_per_node):

Uses Ray for distributed execution (--distributed-executor-backend ray)
Leader nodes: Starts Ray head and runs vLLM; all probes remain active
Worker nodes: Run Ray agents only; all probes (liveness, readiness, startup) are removed

Data Parallel Mode (when world_size × data_parallel_size > GPUs_per_node):

Worker nodes: All probes (liveness, readiness, startup) are removed
Leader nodes: All probes remain active

SGLang Backend

Worker nodes: All probes (liveness, readiness, startup) are removed

TensorRT-LLM Backend

Leader nodes: All probes remain unchanged
Worker nodes:
- Liveness and startup probes are removed
- Readiness probe is replaced with a TCP socket check on SSH port (2222):
  - Initial Delay: 20 seconds
  - Period: 20 seconds
  - Timeout: 5 seconds
  - Failure Threshold: 10

Extracts the docker registry server URLs from each secret’s authentication configuration
Matches the container image’s registry host against the discovered registry URLs
Automatically injects matching secrets as imagePullSecrets in the pod specification

All these defaults can be overridden by explicitly specifying values in your DynamoComponentDeployment or DynamoGraphDeployment resources
User-specified probes (via livenessProbe, readinessProbe, or startupProbe fields) take precedence over operator defaults
For security context, if you provide any securityContext in extraPodSpec, no defaults will be injected, giving you full control
For multinode deployments, some defaults are modified or removed as described above to accommodate distributed execution patterns
The extraPodSpec.mainContainer field can be used to override probe configurations set by the operator
