<title>Set environment variables using the OpenStack RC
file</title>
<para>To set the required environment variables for the OpenStack
command-line clients, you must create an environment file
called an OpenStack rc file, or <filename>openrc.sh</filename>
file.<phrase audience="enduser"> If your OpenStack
installation provides it, you can download the file from
the OpenStack dashboard as an administrative user or any
other user.</phrase> This project-specific environment
file contains the credentials that all OpenStack services
use.</para>
<para>When you source the file, environment variables are set for
your current shell. The variables enable the OpenStack client
commands to communicate with the OpenStack services that run
in the cloud.</para>
<note>
<para>Defining environment variables using an environment file is not a
common practice on Microsoft Windows. Environment variables are usually
defined in the <guilabel>Advanced</guilabel> tab of the System
Properties dialog box.</para>

<title>Download and source the OpenStack RC file</title>
<procedure>
<step>
<para>Log in to the OpenStack dashboard, choose the
project for which you want to download the
OpenStack RC file, and click <guibutton>Access
&amp; Security</guibutton>.</para>
</step>
<step>
<para>On the API Access tab, click <guibutton>Download
OpenStack RC File</guibutton> and save the
file. The filename will be of the form
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
where <replaceable>PROJECT</replaceable> is the
name of the project for which you downloaded the
file.</para>
</step>
<step>
<para>Copy the
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
file to the computer from which you want to run
OpenStack commands.</para>
<para>For example, copy the file to the computer from
which you want to upload an image with a
<command>glance</command> client
command.</para>
</step>
<step>
<para>On any shell from which you want to run
OpenStack commands, source the
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
file for the respective project.</para>
<para>In the following example, the
<filename>demo-openrc.sh</filename> file is
sourced for the demo project:</para>
<screen><prompt>$</prompt> <userinput>source demo-openrc.sh</userinput></screen>
</step>
<step>
<para>When you are prompted for an OpenStack password,

<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
file from scratch, if for some reason you cannot download
the file from the dashboard.</para>

<para>In a text editor, create a file named

export OS_REGION_NAME=<replaceable>regionName</replaceable>
export OS_CACERT=<replaceable>/path/to/cacertFile</replaceable></programlisting>
</step>
<step>
<para>On any shell from which you want to run
OpenStack commands, source the
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>

you source the

<para>You are not prompted for the password with this
method. The password lives in clear text format in the
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
file. Restrict the permissions on this file to avoid
security problems. You can also remove the
<literal>OS_PASSWORD</literal> variable from the
file, and use the <parameter>--password</parameter>
parameter with OpenStack client commands
instead.</para>
</note>
<note audience="enduser">
<para>You must set the OS_CACERT environment variable when
using the https protocol in the OS_AUTH_URL environment setting because
the verification process for the TLS (HTTPS) server certificate uses
the one indicated in the environment. This certificate will be used when
verifying the TLS (HTTPS) server certificate.</para>

<section xml:id="override-variables">
<title>Override environment variable values</title>
<para>When you run OpenStack client commands, you can override
some environment variable settings by using the options
that are listed at the end of the <command>help</command> output
of the various client commands. For example, you can override
the <option>OS_PASSWORD</option> setting in the
<filename><replaceable>PROJECT</replaceable>-openrc.sh</filename>
file by specifying a password on a <command>keystone</command> command, as
follows:</para>
<screen><prompt>$</prompt> <userinput>keystone --os-password <replaceable>PASSWORD</replaceable> service-list</userinput></screen>
<para>Where <replaceable>PASSWORD</replaceable> is your password.</para>
<para>A user specifies their username and password credentials to interact
with OpenStack, using any client command. These credentials can be specified
using various mechanisms, namely, the environment variable or command-line argument.
It is not safe to specify the password using either of these methods.</para>
<para>For example, when you specify your password using the command-line client
with the <parameter>--os-password</parameter> argument, anyone with access
to your computer can view it in plain text with the <literal>ps</literal>
field.</para>
<para>To avoid storing the password in plain text, you can prompt for the
OpenStack password interactively.</para>
