Purpose
This resource handler will be used to discover an instance of a postgres server on a machine in order to satisfy its requirement in an SDD.
Requirements
- The InstalledProductHandler must implement the IResourceHandler from the org.eclipse.cosmos.me.sdd.cr bundle.
- The IResourceHandler class is an interface that the runtime uses to load and run bundles dynamically. The IResourceHandler uses the CIM QName as defined by the component.xml data for the implemented handler as the way the ResourceHandler will discover and run the bundle.
- This handler will look for postgres on the current machine only
- This handler will be able to identify postgres and its version on both Windows and Linux
Design details
- This handler will attempt to determine the OS it is running on. If it is on windows, it will check the windows registry for the key that Postgres uses to identify itself, if it's not found it will look to the default directory it is installed under. If it is linux, it will look for postgres in the /opt and /usr/local directories, following the same pattern as the installed products handler, COSMOS_Design_275731
Impacts of this enhancement
- The SDD runtime will be able to resolve a deployment descriptor that defines a relational database of postgres.
