orchestrate-streaming-stack

description

Orchestrate an end-to-end NVIDIA self-managed streaming stack across AWS or Azure. Use when planning, generating, sequencing, deploying, or validating the full path from CSP base infrastructure through NVCF self-managed control plane, NVCF auxiliary services, caches, storage APIs, and post-deploy readiness gates. Trigger when the user asks for orchestration, full-stack setup, bring-up order, runbook, dependency sequencing, AWS/Azure streaming deployment, csp-infra plus NVCF, caches, or storage API coordination. Do not use for a single component task when the user explicitly asks only for one child skill.

Orchestrate Streaming Stack

Overview

Coordinate the full self-managed streaming deployment without duplicating the component skills. Treat this skill as the top-level runbook: choose the CSP path, load the correct child skills, keep state in streaming-env.sh, and advance only when each phase's readiness gate passes.

Run from the streaming-staging repository root unless a child skill says otherwise.

Safety Rules

• Never ask for, print, echo, grep, decode, or paste secret values. Treat NGC_API_KEY_FILE, cloud credentials, kubeconfigs, registry passwords, and generated secret manifests as sensitive.
• Prefer generate/plan mode unless the user explicitly asks to deploy, apply, run, provision, or execute.
• Before executing cloud-changing commands, confirm the target CSP, account/subscription, region, cluster name, and mode in one concise message.
• Do not skip a readiness gate to continue the sequence. If a gate fails, stop at the failing phase, summarize the failing checks, and route to the owning child skill.
• Keep AWS and Azure assumptions separate. Do not apply AKS load-balancer, ACR, Azure Blob, or Azure CNI details to EKS. Do not apply EKS, ECR, NLB, or IRSA details to AKS.

Mode Detection

Infer the operating mode from the user's prompt:

Mode	Trigger	Behavior
Plan	"plan", "runbook", "sequence", "what order", ambiguous setup language	Produce ordered phases, required inputs, and gates. Do not write deploy scripts unless useful and requested.
Generate	"generate scripts", "draft manifests", "prepare Terraform", "write runbook artifacts"	Generate artifacts for review, then stop. Do not execute.
Deploy	"deploy", "apply", "create", "provision", "run", "bring up"	Generate or use existing artifacts, then execute one phase at a time with stop-on-failure semantics.
Recover	"resume", "continue", "fix failed phase", "rerun from phase N"	Inspect current state and logs first, then continue from the earliest failed or incomplete gate.

When intent is ambiguous, choose Plan or Generate mode and tell the user the exact phrase to use for execution.

Required Context

Collect or discover this context before sequencing work:

Context	Source
CSP	User prompt; if missing, ask AWS or Azure.
Cluster name	streaming-env.sh, generated env files, Terraform outputs, kube context, or user prompt.
Region/location	streaming-env.sh, AWS/Azure CLI config, or user prompt.
Account/subscription	aws sts get-caller-identity for AWS; az account show for Azure.
Artifact mode	Plan, Generate, Deploy, or Recover.
Storage target	Azure Blob, S3, existing object store, or filesystem adapter.
Cache target	DDCS, UCC, GXCache, or none. Prefer DDCS for shader cache when the workload needs Kit/write-render-worker shader caching.
NVCF stack path	User-provided extracted nvcf-self-managed-stack path, or repo-local sample path when the task is only planning.

Use streaming-env.sh at the repo root as the shared env file. If it is missing and work is not read-only planning, copy streaming-env.sh.example to streaming-env.sh, set mode 600, and populate only the values needed for the selected path.

Child Skill Routing

Read the child skill before performing that phase. Open only the provider or component references needed for the selected path.

Phase	Azure child skill	AWS child skill	Notes
Base infra	csp-infra/azure/.agents/skills/aks-bootstrap/SKILL.md	csp-infra/aws/.agents/skills/aws-infra/SKILL.md	Azure has a seven-stage orchestrator. AWS owns Terraform foundation plus GPU Operator.
Registry mirror	csp-infra/azure/.agents/skills/acr-mirror/SKILL.md	csp-infra/aws/.agents/skills/aws-infra/ecr-mirror/SKILL.md	Mirror after registry exists and before installs that require private pulls.
NVCF prerequisites	nvcf/.agents/skills/nvcf-self-managed-prerequisite/SKILL.md	same	Installs cluster prerequisites such as KAI/SMB CSI when required by the selected NVCF stack path.
NVCF control plane	nvcf/.agents/skills/nvcf-self-managed-installation/SKILL.md	same	Requires extracted stack path, helmfile 1.1.x, helm-diff, kubectl, NGC auth, and gateway domain.
NVCF CLI	nvcf/.agents/skills/nvcf-self-managed-cli/SKILL.md	same	Use for post-install function and CLI interaction when requested.
LLS	nvcf/.agents/skills/nvcf-lls-install/SKILL.md with providers/kubernetes.md	same	Required for WebRTC/UDP media ingress.
GXCache	caches/.agents/skills/nvcf-gxcache/SKILL.md with providers/kubernetes.md	same	Use when specifically requested or required by the target stack.
DDCS	caches/.agents/skills/caches-ddcs-deploy/SKILL.md	same, adapt provider assumptions	Use for Kit/write-render-worker shader cache. GKE examples in the skill are not AWS/Azure defaults.
OV Content Cache	caches/.agents/skills/caches-ovcontentcache-deploy/SKILL.md	same	Use when OV Content Cache is part of the requested cache layer.
Storage APIs	storage/.agents/skills/ovstorage/SKILL.md, then its GUIDE.md	same	Choose Azure/S3 production adapter or example adapter from the storage skill's decision tree.

End-to-End Sequence

Phase 0 - Preflight

1. Confirm mode, CSP, account/subscription, region, cluster name, and whether commands will execute.
2. Verify local tools for the selected path:
   • Common: kubectl, helm, jq, curl, python3.
   • NVCF: helmfile 1.1.x and helm-diff.
   • Azure: az, and terraform only if generating Terraform artifacts.
   • AWS: aws, terraform.
   • Registry mirroring: skopeo or the child skill's selected mirror backend.
3. Check NGC_API_KEY_FILE exists and is non-empty without printing its contents.
4. Inspect image-manifest/manifest.yaml for chart/image versions before pinning versions manually.

Gate: toolchain exists, identity matches target, streaming-env.sh has required non-secret values, and no secrets were exposed.

Phase 1 - Base CSP Infrastructure

Azure:

1. Load aks-bootstrap.
2. Use its mode detection and required streaming-env.sh variables.
3. Generate or execute stages 01-07 in order.

AWS:

1. Load aws-infra.
2. Generate or apply Terraform for VPC, subnets, EKS, node groups, IAM, and ECR.
3. Install GPU Operator after kubeconfig works.

Gate: kubectl cluster-info succeeds, GPU nodes can become schedulable, GPU Operator is healthy, registry exists, and provider storage primitives exist or are explicitly deferred.

Phase 2 - Registry Mirror

Mirror images and charts only after base infra creates the target registry.

• Azure: load acr-mirror and mirror to ACR.
• AWS: load aws-infra/ecr-mirror and mirror to ECR.

OCI vs non-OCI charts. The manifest has a mix of OCI and non-OCI artifacts. Container images (nvcr.io/...) are already OCI and mirror as-is. Some Helm charts are published to an https:// Helm repository (for example helm.ngc.nvidia.com). Those are not OCI and cannot be resolved by global.helm.sources (OCI) or mirrored directly. Before pointing the stack at your mirror, convert each https:// chart to OCI: helm repo add / helm pull the .tgz, then helm push <chart>.tgz oci://<your-registry>/<mirror-sub-path>. Only OCI charts can live under global.helm.sources.

Gate: target registry contains required images/charts for NVCF, LLS, caches, and storage components selected for the deployment.

Phase 3 - NVCF Prerequisites and Control Plane

1. Load nvcf-self-managed-prerequisite for cluster prerequisites required by the selected stack.
2. Load nvcf-self-managed-installation for the extracted nvcf-self-managed-stack.
3. In <nvcf-self-managed-stack>/environments/base.yaml, set:

   addon:
     lls:
       enabled: true
   

   If TURN enablement is not automatically derived from the addon flag, set this in <nvcf-self-managed-stack>/global.yaml.gotmpl:

   notary:
     turn:
       enabled: true
   

4. Configure gateway/domain values from the provider ingress/LB output.
5. Run helmfile template before helmfile sync.

Gate: dependency namespaces are healthy, NVCF API/backend services are ready, ingress routes exist, and the selected gateway host resolves or is otherwise reachable for validation.

Phase 4 - NVCF Auxiliary Services

Install only the services required by the target workload:

1. LLS for WebRTC/UDP streaming. Load the Kubernetes provider guide and apply the notes for the target cluster.
2. GXCache only when the stack or workload requires it.
3. DDCS for shader cache when Kit/write-render-worker startup shader compilation needs acceleration. Install with --set monitoring.enabled=false when Prometheus CRDs (e.g. PodMonitoring) are not present on the cluster.
4. UCC when object/content cache is in scope.

Gate: service rollouts complete, provider LoadBalancers or Services have addresses, UDP 5004 is reachable for LLS, and cache health/proof-of-life checks pass.

Phase 5 - Storage API

1. Load storage/.agents/skills/ovstorage/SKILL.md.
2. Read GUIDE.md in that skill directory.
3. Choose adapter:
   • S3 production adapter for AWS.
   • Azure production adapter for Azure.
   • Example filesystem adapter for development or custom adapter work.
4. Deploy Discovery plus the selected adapter, then optional Event Aggregation, Event Consumer, RabbitMQ, Envoy Auth Extension, Storage Navigator, and ingress only when requested.

Gate: Discovery answers, adapter CRUD works, notifications/permissions checks pass when enabled, and storage endpoint details are recorded for downstream functions.

Phase 6 - Final Readiness

Run a concise acceptance pass:

• kubectl get pods -A has no unexpected CrashLoopBackOff, ImagePullBackOff, or Pending pods.
• GPU allocatable resources are visible.
• NVCF API health and auth path are reachable.
• LLS/media path is validated when streaming is in scope.
• Cache proof-of-life passes for selected cache services.
• Storage API CRUD and Discovery checks pass.
• Generated artifacts and env files are listed with paths.

Recovery Workflow

For resume or repair requests:

1. Identify the last completed gate from generated scripts, Terraform outputs, Helm releases, namespaces, and pod state.
2. Do not rerun earlier destructive phases unless the child skill declares them idempotent.
3. Route to the owning child skill for the failed phase.
4. After fixing, rerun the failed phase's gate, then continue the top-level sequence.

Output Format

For Plan or Generate mode, return a phase table:

Phase	Owner skill	Action	Gate	Status

For Deploy or Recover mode, report after every phase:

• Completed action.
• Artifact paths created or used.
• Gate result.
• Next phase and what it needs.

Keep the final answer short, with the current state, failed gate if any, and exact next command or prompt needed.
