Translations:OpenStack command line clients/4/en

On East-cloud there are two RC files to choose from a v2.0 and a v3 file. Unless you have a specific reason to choose the v2.0 file, choose the v3 file. If your openstack client version is version 2.5.0 or later, the East-cloud v3 file must have the line export OS_IDENTITY_API_VERSION=3 added to it. Finally if switching between different RC files (e.g. east and west cloud RC files) you should be careful of environment variables which may still be set from the previous RC file, these may cause your OpenStack client commands to fail. You can either ensure that all environment variables set in the RC file are unset with unset <variable-name> commands for each variable, or start a fresh new session without any of the RC environment variables set.
