README:
|
||||
|
||||
This CSAR contains all definitions that are required for deploying WordPress
|
||||
and MySQL on a single compute instance.
|
||||
|
||||
Entry information for processing through an orchestrator is contained in file
|
||||
TOSCA-Metadata/TOSCA.meta. This file provides high-level information such as
|
||||
CSAR version or creator of the CSAR. Furthermore, it provides pointers to the
|
||||
various TOSCA definitions files that contain the real details.
|
||||
The entry 'Entry-Definitions' points to the definitions file which holds the
|
||||
service template for the workload.
|
||||
'Entry-Definitions' is optional. An orchestrator can also process the contents
|
||||
like this:
|
||||
1) Read in and process each definitions file.
|
||||
2) For each definitions file:
|
||||
2.1) Read in all * type definitions (node types, capability types, etc.) and
|
||||
store them in an internal map
|
||||
3) Verify and build dependencies (e.g. inheritance) between all type definitions
|
||||
previously read in. Orchestrator built-in types (e.g. TOSCA base types) are
|
||||
also considered in this step.
|
||||
4) Process the actual service template (the file with a node_templates section).
|
||||
Validate using previously obtained type information.
