  - listAssignableLocations
```
public Set<? extends Location> listAssignableLocations()
```
    Description copied from interface: BlobStore
    
    The get locations command returns all the valid locations for containers. A location has a scope, which is typically region or zone. A region is a general area, like eu-west, where a zone is similar to a datacenter. If a location has a parent, that implies it is within that location. For example a location can be a rack, whose parent is likely to be a zone.

```
public boolean createContainerInLocation(Location location,
                                String container)
```
    Description copied from interface: BlobStore
    
    Creates a namespace for your blobs
    A container is a namespace for your objects. Depending on the service, the scope can be global, identity, or sub-identity scoped. For example, in Amazon S3, containers are called buckets, and they must be uniquely named such that no-one else in the world conflicts. In other blobstores, the naming convention of the container is less strict. All blobstores allow you to list your containers and also the contents within them. These contents can either be blobs, folders, or virtual paths.
    
    Specified by:
    
    createContainerInLocation in interface BlobStore
    
    Parameters:
    location - some blobstores allow you to specify a location, such as US-EAST, for where this container will exist. null will choose a default location
    container - namespace. Typically constrained to lowercase alpha-numeric and hyphens.
    
    Returns:
    true if the container was created, false if it already existed.
