Environment Variables

All of the global configuration options that are not built into the UI are set via environment variables. A fairly exhaustive list of all of the options can be found here.

There are defaults set in the code so changing/settings these values is not required to use Danswer. A few notable settings that are more frequently changed however are the following:

• AUTH_TYPE (default value is disabled)
• MULTILINGUAL_QUERY_EXPANSION (you can provide a comma separated list of languages for query rephrasing such as English,French)
• LOG_LEVEL (default is info)

​

Docker Compose

There are several ways to configure environment variables for the containers. For Docker Compose, there are many ways to pass environment variables to the container, any of the standard approaches will work. However the preferred approach for Danswer is to use the .env file. To do this, create a file called .env at danswer/deployment/docker_compose/.env. From there, populate it with the values you want to override:

# Configures basic email/password based login
AUTH_TYPE="basic"

# Rephrasing the query into different languages to improve search recall
MULTILINGUAL_QUERY_EXPANSION="English,Spanish,German"

# Set a cheaper/faster LLM for the flows that are easier (such as translating the query etc.)
FAST_GEN_AI_MODEL_VERSION="gpt-3.5-turbo"

# Setting more verbose logging
LOG_LEVEL="debug"
LOG_ALL_MODEL_INTERACTIONS="true"

Kubernetes

For Kubernetes, the deployment yaml files includes an Environment ConfigMap. Simply update the values in the file here.
