# Modify the Environment Files

The Knowledge Discovery Docker Compose ZIP package contains environment files.

For all Knowledge Discovery Docker Compose options, you must modify the `.env` environment file to provide the details of your license server.

NOTE: To use SSL, you must also modify the `idol-ssl.env` environment file to configure SSL behavior (see SSL Environment Variable Reference).

To modify the standard environment file

1. In your Docker Compose package directory, open the folder for the setup that you want to run (`basic-idol` or `data-admin`).

2. Open the `.env` environment file in a text editor.

3. Update the `LICENSESERVER_IP` variable to give the IP address of your License Server.

   NOTE: To work with the standard Knowledge Discovery Docker images, License Server must run on port 20000.

4. (Optional) Modify the following variables for your setup:

   HTTP_PROXY | The URL of a HTTP proxy that Docker must use to access the container files on Docker Hub.
   IDOL_SERVER_VERSION | The Knowledge Discovery version of the images that you want to download. You can use one of the following version string formats: 12.X Download the latest version of the 12.X release containers. For example, 12.6 downloads the latest available 12.6 version (which might be 12.6.0 or 12.6.1, and so on). 12.X.X Download the latest version of the 12.X.X release containers. For example, 12.6.0 downloads the latest available 12.6.0 version, where the docker containers have been updated but the component versions have not changed. 12.X.X_DockerBuild Download an exact version of the Knowledge Discovery Docker containers.

   The other environment variables are for internal use, and you do not need to update them unless instructed by OpenText Support.

5. Save and close the environment variables file.
