Trove Sample Configuration File

Configure Trove by editing /etc/trove/trove.conf.

No config file is provided with the source code, it will be created during the installation. In case where no configuration file was installed, one can be easily created by running:

tox -e genconfig

To see configuration options available, please refer to Trove Configuration Options.

The following is a sample Trove configuration for adaptation and use. It is auto-generated from Trove when this documentation is built, and can also be viewed in file form.
