# Required Privileges | ||
|
||
In order to succesfully deploy an OpenShift cluster on OpenStack, the user passed to the installer needs a particular set of permissions in a given project. Our recommendation is to create a user in the project that you intend to install your cluster onto with the role *member*. In the event that you want to customize the permissions for a more restricted install, the following use cases can accomodate them. | ||
|
||
## Bring Your Own Networks | ||
|
||
Using the [bring your own networks feature](https://github.com/openshift/installer/blob/master/docs/user/openstack/customization.md#custom-subnets) will allow you use already prepared networking infrastructure. This would mean that an installation using this feature will only need permissions to read Private Networks, Subnets, and Routers. The user will still need to be able to create ports and tags on these interfaces though. | ||
|
||
## Floating IP Free Installs | ||
|
||
By leaving the `externalNetwork`, `ingressFloatingIP`, and `appsFloatingIP` fields empty, you can run the installer without creating, deleting, or modifying any floating IPs. Running the installer this way does not require you to have any Floating IP Privileges. |
