description	Use when documenting, reviewing, installing, configuring, or operating MLflow in Red Hat OpenShift AI from the official Working with MLflow guide: shared cluster MLflow instance, project-to-workspace mapping, Kubernetes RBAC authorization, DataScienceCluster mlflowoperator enablement, MLflow and MLflowConfig custom resources, SQLite/PVC development deployments, PostgreSQL and S3-compatible production-oriented deployments, aggregate ClusterRoles, MLflow pseudo-resources, SDK installation and authentication, kubernetes-namespaced auth, local workstation and pod environment variables, version compatibility, experiment tracking, and project-specific artifact storage. Do NOT use for project/workbench lifecycle (use rhoai-project-workflows), generic S3 object operations (use rhoai-s3-object-storage-data), OpenShift AI model registry workflows (use rhoai-model-registry or rhoai-model-registry-workflows), formal custom evaluation workflows (use rhoai-model-evaluation), Gen AI playground prompt workflows outside MLflow availability checks (use rhoai-gen-ai-playground), or live cluster changes without the OpenShift safety guard.

RHOAI MLflow

Use this skill for Red Hat OpenShift AI MLflow platform and SDK workflows on the active product baseline in docs/PLATFORM_BASELINE.md.

Source Grounding

Read references/source-capture.md before using product workflow details. Official Red Hat documentation is product authority. This skill adapts the official Working with MLflow guide to this repo's demo workflow and GitOps review model.

Scope

This skill covers:

• MLflow concept model in OpenShift AI
• single shared MLflow instance deployed through the MLflow Operator
• one-to-one mapping from OpenShift projects to MLflow workspaces
• Kubernetes RBAC authorization through MLflow pseudo-resources
• enabling the mlflowoperator component on the DataScienceCluster
• cluster-scoped MLflow custom resource named mlflow
• namespace-scoped MLflowConfig custom resource named mlflow
• development/test storage with SQLite and PVC-backed artifacts
• production-oriented storage with PostgreSQL and S3-compatible object storage
• aggregate mlflow-view, mlflow-edit, and mlflow-integration roles
• MLflow SDK installation and kubernetes-namespaced authentication
• local workstation and in-cluster pod SDK configuration
• compatible MLflow server and SDK versions
• experiment tracking with parameters, metrics, and artifacts
• project-specific S3 artifact storage overrides
• common MLflow SDK troubleshooting signals

Use other skills for adjacent work:

• rhoai-project-workflows for project lifecycle, workbench lifecycle, project access, project connections, and connection creation
• rhoai-s3-object-storage-data for Boto3 and general object operations from workbenches
• rhoai-model-registry for OpenShift AI model registry administrator provisioning
• rhoai-model-registry-workflows for OpenShift AI model registry user workflows
• rhoai-gen-ai-playground for product prompt workflows that rely on MLflow availability
• rhoai-model-customization-training for Training Hub MLflow tracking parameters, run evidence, and rank-0 distributed logging context
• rhoai-evaluation for official EvalHub MLflow tracking and evaluation result evidence workflows
• rhoai-model-evaluation for custom EvalHub, LM-Eval, RAGAS, and MLflow-backed evidence workflows outside the MLflow product guide
• rhoai-dashboard-customization for dashboard feature flags and application visibility
• rhoai-api-tiers for MLflow REST API and mlflows.opendatahub.io/v1 support posture

Demo Policy

For this repo:

• Treat MLflow as the tracking and evidence store for experiments, runs, metrics, artifacts, prompts, datasets, traces, and registered model records when the demo needs those lifecycle records.
• Manage project and workspace lifecycle through OpenShift AI projects. Do not claim the MLflow API creates, updates, or deletes workspaces.
• Use GitOps for the cluster-level MLflow deployment once active manifests exist, but verify fields with official docs or oc explain before authoring.
• Use SQLite and file/PVC artifacts only for development, testing, or small demo flows. Label this as non-production.
• Use PostgreSQL and S3-compatible artifact storage for production-shaped enterprise narratives.
• Store database URIs with credentials in Secrets referenced by backendStoreUriFrom; do not commit database credentials.
• Keep S3 credentials in project-scoped connections or Secrets. Never commit access keys, secret keys, session tokens, or bucket-specific credentials.
• When serveArtifacts is enabled, do not set defaultArtifactRoot to a direct s3:// URI that bypasses the MLflow server artifact proxy.
• For per-project artifact overrides, use a project Secret named mlflow-artifact-connection and an MLflowConfig named mlflow.
• Prefer MLFLOW_TRACKING_AUTH=kubernetes-namespaced over manual token exports. Treat manual MLFLOW_TRACKING_TOKEN use as local troubleshooting, not production guidance.
• Use MLFLOW_TRACKING_INSECURE_TLS=true only for the demo's accepted self-signed certificate posture.

Workflow

1. Confirm the active baseline in docs/PLATFORM_BASELINE.md.
2. Read references/source-capture.md and references/official-doc-extraction.md.
3. Decide whether the task is:
   • MLflow concept or README authoring
   • cluster-level MLflow Operator enablement
   • MLflow custom resource review
   • storage and database configuration
   • RBAC and API authorization review
   • SDK installation and authentication
   • local workstation or in-pod SDK setup
   • experiment tracking code review
   • project-specific artifact storage override
   • troubleshooting MLflow SDK errors
4. Use examples/mlflow-patterns.md for focused review patterns.
5. For live cluster work, follow the OpenShift safety guard in AGENTS.md.
6. Validate with references/validation-checklist.md.
