Is it possible to install nova-objectstore on a machine different with the one where nova-api is installed?

I tried to install nova-objectstore on a different machine with the one where nova-api. But When I added images using the command "uec-publish-tarball", the error occurred.

And I found the that the novarc created by nova-manage command was wrong. The value of S3_URL is the ip address of the local machine where the uec-publish-tarball was executed.

Here is my question. Is it possible to install nova-objectstore on a machine different with the one where nova-api is installed?

Thanks.
