Environment variables in <code>.env</code> always take precedence over other sources.</p>

<p>For deployments managed with the Terminal User Interface (TUI), this file is located at <code>~/.openrag/tui</code>, and it can be created automatically during <a class="" href="/install-options">installation</a>.</p>
|

<p>For <a class="" href="/docker">self-managed deployments</a>, this file can be located at the root of your OpenRAG project directory or referenced from another location.</p>

<p>If a variable isn't set, OpenRAG uses default or fallback values where available.
|
||
Not all variables have default values, and errors can occur if required variables aren't set.
|
||
Default values can be found in the reference tables on this page and in <a href="https://github.com/langflow-ai/openrag/blob/main/src/config/config_manager.py" target="_blank" rel="noopener noreferrer" class=""><code>config_manager.py</code></a>, <a href="https://github.com/langflow-ai/openrag/blob/main/src/config/settings.py" target="_blank" rel="noopener noreferrer" class=""><code>settings.py</code></a>, and <a href="https://github.com/langflow-ai/openrag/blob/main/src/utils/logging_config.py" target="_blank" rel="noopener noreferrer" class=""><code>logging_config.py</code></a>.</p>
|
||
<p>You can <a class="" href="/agents#modify-a-flow-at-runtime">temporarily set Langflow variables at runtime</a>.
|
||
However, these temporary overrides don't overlap with most OpenRAG environment variables.
|
||
The only exceptions are flow-level Langflow settings, such as the language model used in a flow.</p>

|
||
<p>During <a class="" href="/install-options">installation</a>, an initial <code>.env</code> file is created automatically or manually.
|
||
You can edit this file to change OpenRAG configuration settings after installation.</p>
|
||
<p>Each OpenRAG environment variable is either mutable or immutable.
|
||
This determines the actions you must take to apply changes after editing the <code>.env</code> file:</p>
|
||
<ul>
|
||
<li class="">
|
||
<p><strong>Mutable environment variables</strong>: You can apply changes to mutable environment variables by <a class="" href="/manage-services">stopping and restarting the OpenRAG services</a> after editing the <code>.env</code> file.</p>
|
||
</li>
|
||
<li class="">
|
||
<p><strong>Immutable environment variables</strong>: You must <a class="" href="/reinstall">redeploy OpenRAG</a> with your modified <code>.env</code> file if you change immutable environment variables.</p>
|
||
</li>
|
||
</ul>

|
||
<p>Configure which models and providers OpenRAG uses to generate text and embeddings.
|
||
You only need to provide credentials for the providers you are using in OpenRAG.</p>
|
||
<p>These variables are initially set during the <a class="" href="/install#application-onboarding">application onboarding process</a>.
|
||
Some of these variables are immutable and can only be changed by redeploying OpenRAG, as explained in <a href="#set-environment-variables" class="">Set environment variables</a>.</p>
