Environment variables

ACCEPT_EULA

POSTGRES_PASSWORD

The PostgreSQL administrator password.

GUACAMOLE_DATABASE

The name of the database to create and initialized for use with Apache Guacamole. This environment variable ultimately maps to the POSTGRES_DB environment variable of the official PostgreSQL image. If omitted, the default value defined by the official PostgreSQL image will be used.

The GUACAMOLE_DATABASE variable is provided here for consistency with the other Guacamole-specific variables and may be omitted if POSTGRES_DB is provided.

GUACAMOLE_ADMIN_PASSWORD

This is the Administrator password for the guacadmin user.

GUACAMOLE_USERNAME and GUACAMOLE_PASSWORD

Docker secrets

Rather than pass data directly in environment variables, a _FILE suffix may be added to any environment variable supported by this image to force that variable to be read from the named file within the container. As Docker secrets store sensitive data within files beneath /run/secrets/ within the container, this can be used to load sensitive data from Docker secrets.

For example, to load the username and password for the limited-privilege user specific to the Guacamole web application from Docker secrets:

docker run --name some-guacamole-db \
    -e ACCEPT_EULA=Y \
    -e GUACAMOLE_DATABASE=guacamole_db \
    -e POSTGRES_PASSWORD=some_password \
    -e GUACAMOLE_ADMIN_PASSWORD=some_password \
    -e GUACAMOLE_USERNAME_FILE=/run/secrets/postgres-username \
    -e GUACAMOLE_PASSWORD_FILE=/run/secrets/postgres-password \
    -d keeper/guacamole-db-postgres
