Deployment pipeline¶

A sequence of data transformations from user-friendly instructions to the low-level data representation in the form of deployment input data and deployment graph.

The deployment pipeline workflow:

1. Fuel manipulates the input data provided by the user. Data examples:
   • Cluster attributes
   • OpenStack release version
   • Networking settings
   • Huge Pages allocation
2. Fuel converts the data using a set of serializers.
3. Using the converted data, Fuel builds a deployment graph.
4. Fuel passes the deployment graph to a task executor.
5. The task executor carries out the deployment tasks based on the input data.
