hi Abhishek,
For this scenario I think you should be able to use something like
ManagementContext mgmt = this.getManagementContext();
Location loc =
mgmt.getLocationRegistry().resolve("location-name-defined-in-brooklyn.properties”)
(or see [2] in the test code, BlobStoreTest.java).
Then you can use location.getConfig with appropriate keys to get the
credentials and endpoint you need to create an object to manage the blob store.
See example code as in [1] below.
In general to get access to properties from the brooklyn.properties file you
can managementContext.getConfig(). However, in general this isn’t the best way
to access that information, e.g. particularly in the case of locations it’s
better to let Brooklyn parse the file and build up its own idea of the
locations - including understanding the location hierarchy, for example if the
identity & credential is defined at top level, but you have some more specific
prperties in your location like endpoint and container name. Once it has done
all that work then you can use the location registry methods above to access
and use the locations more conveniently.
Hope this is of some use.
Best regards
Geoff Macartney
