Key Configuration Files

Deployment Configuration (preferred): Embedded in pyproject.toml under [tool.llamadeploy].

[tool.llamadeploy]
name = "my-deployment"
app = "path.to.module:app"  # or use `workflows = { my_workflow = "path.to.module:workflow" }`

[tool.llamadeploy.ui]
directory = "./ui"
# Optional overrides:
# build_output_dir = "dist"
# package_manager = "pnpm"
# build_command = "build"
# serve_command = "dev"
# proxy_port = 4502

Alternative: llama_deploy.toml or llama_deploy.yaml with the same schema as [tool.llamadeploy].

Helm Chart: charts/llama-agents/values.yaml Kubernetes CRD: operator/config/crd/bases/deploy.llamaindex.ai_llamadeployments.yaml RBAC: operator/config/rbac/role.yaml
