# Configuring a proxy for outgoing Keycloak HTTP requests

Security Assertion Markup Language (SAML) allows you to access multiple web-based applications using a single set of authentication credentials. It is possible to configure Keycloak to access a SAML server via a preconfigured proxy in situations where Keycloak’s host doesn’t have direct access to the internet.

1. Open a terminal and log in to your instance of Anaconda Server as an admin.

2. Open your installer file, where the `docker-compose.yml` file is located by running the command:

   ```sh theme={null}
   # Replace <INSTALLER_LOCATION> with the location of your installer file (where the ``docker-compose.yml`` file is)
   cd <INSTALLER_LOCATION>
   ```

   <Tip>
     You can see all the files contained in your current directory location by running the command `ls -la` in the terminal. You can look for the `docker-compose.yml` file this way, if necessary.
   </Tip>

3. Open your `docker-compose.yml` file using your preferred file editor.

4. Find the `Keycloak` service section of the file, and under `environment:`, add the following lines:

   ```sh theme={null}
   # Replace <PROXY_SITE_URL> with the URL of your SAML proxy
   HTTP_PROXY: <PROXY_SITE_URL>
   HTTPS_PROXY: <PROXY_SITE_URL>
   ```

5. Save your work and close the file. To verify your changes were saved, you can run the command:

   ```sh theme={null}
   cat docker-compose.yml
   ```

   Here is an excerpt from a `docker-compose.yml` file to show you what your Keycloak section might look like.

   ```sh theme={null}
     keycloak:
       image: ${DOCKER_REGISTRY}keycloak:${VERSION}
       environment:
       - KC_DB_URL_HOST=${POSTGRES_HOST}
       - KC_DB_URL_PORT=5432
       - KC_DB_URL_DATABASE=keycloak
       - KC_DB_USERNAME=keycloak
       - KC_DB_PASSWORD=keycloak
       - KC_HOSTNAME=${DOMAIN}
       - KC_PROXY=edge
       - KC_HOSTNAME_STRICT_HTTPS=false
       - KC_HTTP_ENABLED=true
       - HTTP_PROXY: <PROXY_IP>:<PROXY_PORT>
       - HTTPS_PROXY: <PROXY_IP>:<PROXY_PORT>
   ```

6. Restart your instance of Anaconda Server.

   ```sh theme={null}
   docker compose down
   docker compose up -d
   ```
