This allows you to use your chosen model within {{elastic-sec}}. You’ll first need to set up a reverse proxy to communicate with {{elastic-sec}}, then set up LM Studio on a server, and finally configure the connector in your Elastic deployment.

Configure the OpenAI connector in your Elastic deployment. + +## Step 1: Configure your host server + +1. (Optional) If you plan to use a gated model (such as Llama 3.1) or a private model, create a [Hugging Face user access token](https://huggingface.co/docs/hub/en/security-tokens). + 1. Log in to your Hugging Face account. + 2. Navigate to **Settings > Access Tokens**. + 3. Create a new token with at least `read` permissions. Save it in a secure location. +2. Create an OpenAI-compatible secret token. Generate a strong, random string and save it in a secure location. You need the secret token to authenticate communication between {{ecloud}} and your Nginx reverse proxy. +3. Install any necessary GPU drivers. + +## Step 2: Run your vLLM container + +To pull and run your chosen vLLM image: + +1. Connect to your server using SSH. +2.

This is the version of vLLM we recommend. +`--model`: ID of the Hugging Face model you wish to serve. In this example it represents the `Mistral-Small-3.2-24B` model. +`--tool-call-parser mistral \`, `--tokenizer-mode mistral \`, `--config-format mistral \`, and `--load-format mistral`: Mistral specific parameters, refer to the Hugging Face model card for recommended values. +`-enable-auto-tool-choice`: Enables automatic function calling. +`--gpu-memory-utilization 0.90`: Limits max GPU used by vLLM (may vary depending on the machine resources available). +`--tensor-parallel-size 2`: This value should match the number of available GPUs (in this case, 2). This is critical for performance on multi-GPU systems. +===== + +3. Verify the container's status by running the `docker ps -a` command. The output should show the value you specified for the `--name` parameter. + +## Step 3: Expose the API with a reverse proxy + +This example uses Nginx to create a reverse proxy. This improves stability and enables monitoring by means of Elastic's native Nginx integration. The following example configuration forwards traffic to the vLLM container and uses a secret token for authentication. + +1. Install Nginx on your server. +2. Create a configuration file, for example at `/etc/nginx/sites-available/default`. Give it the following content: + +``` +server { + listen 80; + server_name ; + return 301 https://$server_name$request_uri; +} + +server { + listen 443 ssl http2; + server_name ; + + ssl_certificate /etc/letsencrypt/live//fullchain.pem; + ssl_certificate_key /etc/letsencrypt/live//privkey.pem; + + location / { + if ($http_authorization != "Bearer ") { + return 401; + } + proxy_pass http://localhost:8000/; + } +} +``` + +3. Enable and restart Nginx to apply the configuration. + +:::{note} +For quick testing, you can use [ngrok](https://ngrok.com/) as an alternative to Nginx, but it is not recommended for production use. +::: + +## Step 4: Configure the connector in your elastic deployment + +Finally, create the connector within your Elastic deployment to link it to your vLLM instance. + +1. Log in to {{kib}}. +2. Navigate to the **Connectors** page, click **Create Connector**, and select **OpenAI**. +3. Give the connector a descriptive name, such as `vLLM - Mistral Small 3.2`. +4. In **Connector settings**, configure the following: + * For **Select an OpenAI provider**, select **Other (OpenAI Compatible Service)**. + * For **URL**, enter your server's public URL followed by `/v1/chat/completions`. +5. For **Default Model**, enter `mistralai/Mistral-Small-3.2-24B-Instruct-2506` or the model ID you used during setup. +6. For **Authentication**, configure the following: + * For **API key**, enter the secret token you created in Step 1 and specified in your Nginx configuration file. + * If your chosen model supports tool use, then turn on **Enable native function calling**. +7. Click **Save** +8. Finally, open the **AI Assistant for Security** page using the navigation menu or the [global search field](/explore-analyze/find-and-organize/find-apps-and-objects.md). + * On the **Conversations** tab, turn off **Streaming**. + * If your model supports tool use, then on the **System prompts** page, create a new system prompt with a variation of the following prompt, to prevent your model from returning tool calls in AI Assistant conversations: + + ``` + You are a model running under OpenAI-compatible tool calling mode. + + Rules: + 1. When you want to invoke a tool, never describe the call in text. + 2. Always return the invocation in the `tool_calls` field. + 3. The `content` field must remain empty for any assistant message that performs a tool call. + 4. Only use tool calls defined in the "tools" parameter. + ``` + +Setup is now complete. The model served by your vLLM container can now power Elastic's generative AI features. + + +:::{note} +To run a different model, stop the current container and run a new one with an updated `--model` parameter. +::: \ No newline at end of file diff --git a/solutions/security/ai/set-up-connectors-for-large-language-models-llm.md b/solutions/security/ai/set-up-connectors-for-large-language-models-llm.md index 7c28c156f4..7cdc90c367 100644 --- a/solutions/security/ai/set-up-connectors-for-large-language-models-llm.md +++ b/solutions/security/ai/set-up-connectors-for-large-language-models-llm.md @@ -33,9 +33,10 @@ Follow these guides to connect to one or more third-party LLM providers: * [OpenAI](/solutions/security/ai/connect-to-openai.md) * [Google Vertex](/solutions/security/ai/connect-to-google-vertex.md) -## Connect to a custom local LLM +## Connect to a self-managed LLM -You can [connect to LM Studio](/solutions/security/ai/connect-to-own-local-llm.md) to use a custom LLM deployed and managed by you. +- You can [connect to LM Studio](/solutions/security/ai/connect-to-own-local-llm.md) to use a custom LLM deployed and managed by you. +- For air-gapped environments, you can [connect to vLLM](/solutions/security/ai/connect-to-vLLM.md). ## Preconfigured connectors diff --git a/solutions/toc.yml b/solutions/toc.yml index df2ad35fcc..4f3e62f61d 100644 --- a/solutions/toc.yml +++ b/solutions/toc.yml @@ -575,6 +575,7 @@ toc: - file: security/ai/connect-to-openai.md - file: security/ai/connect-to-google-vertex.md - file: security/ai/connect-to-own-local-llm.md + - file: security/ai/connect-to-vLLM.md - file: security/ai/use-cases.md children: - file: security/ai/triage-alerts.md
