<p>This guide demonstrates deploying Langflow on a Kubernetes cluster.</p>

<p>Two charts are available at the <a href="https://github.com/langflow-ai/langflow-helm-charts" target="_blank" rel="noopener noreferrer">Langflow Helm Charts repository</a>:</p>
|

<ul>
|
||
<li>Deploy the <a href="#deploy-the-langflow-ide">Langflow IDE</a> for the complete Langflow development environment.</li>
|
||
<li>Deploy the <a href="#deploy-the-langflow-runtime">Langflow runtime</a> to deploy a standalone Langflow application in a more secure and stable environment.</li>
|

</ul>

<p>The Langflow IDE deployment is a complete environment for developers to create, test, and debug their flows. It includes both the API and the UI.</p>

<p>To inject secrets and Langflow global variables, use the <code>secrets</code> and <code>env</code> sections in the <a href="https://github.com/langflow-ai/langflow-helm-charts/blob/main/charts/langflow-runtime/values.yaml" target="_blank" rel="noopener noreferrer">values.yaml</a> file.</p>
|
||
<p>For example, the <a href="https://raw.githubusercontent.com/langflow-ai/langflow-helm-charts/refs/heads/main/examples/flows/basic-prompting-hello-world.json" target="_blank" rel="noopener noreferrer">example flow JSON</a> uses a global variable that is a secret. When you export the flow as JSON, it's recommended to not include the secret.</p>
|
||
<p>Instead, when importing the flow in the Langflow runtime, you can set the global variable in one of the following ways:</p>
