This section describes the workflow for uploading a Cloudify blueprint to a Cloudify management environment. mermaid.initialize({startOnLoad:true}); sequenceDiagram participant CLI participant NP as Nginx (Proxy) participant REST participant NF as Nginx (Fileserver) participant PSQL as PostgreSQL CLI-CLI: cfy blueprints upload CLI-CLI: Parse blueprint CLI-NP: POST /blueprints NP-NP: validate blueprint size NP-REST: POST /blueprints REST-NF:Copy blueprint & resources REST-PSQL:Save parsed blueprint

Deployment Creation Workflow

This section describes the workflow for creating a deployment for a blueprint. mermaid.initialize({startOnLoad:true}); sequenceDiagram participant CLI participant NP as Nginx (Proxy) participant REST participant ES as Elasticsearch participant MA as Management Agent CLI-NP: cfy deployments create - PUT /deployments/{{deployment-id}} NP-CLI: PUT /deployments/{{deployment-id}} REST-ES: get blueprint by ID REST-REST: create deployment data REST-ES: save deployment data REST-MA:create deployment agents The REST service retrieves the blueprint document from Elasticsearch and creates a tangible manifestation of it by expanding nodes to node-instances, attaching node-instance ID’s to them, and so on.
