FATAL: Missing required environment variables
-------------------------------------------------------------------------------
If using a SQLServer database, you must provide each of the following
environment variables or their corresponding Docker secrets by appending _FILE
to the environment variable, and setting the value to the path of the
corresponding secret:
SQLSERVER_USER The user to authenticate as when connecting to
SQLServer.
SQLSERVER_PASSWORD The password to use when authenticating with SQLServer
as SQLSERVER_USER.
SQLSERVER_DATABASE The name of the SQLServer database to use for Guacamole
authentication.

FATAL: Missing SQLSERVER_HOSTNAME or "sqlserver" link.

If using a SQLServer database, you must either:
(a) Explicitly link that container with the link named "sqlserver".
(b) If not using a Docker container for SQLServer, explicitly specify the TCP
connection to your database using the following environment variables:
SQLSERVER_HOSTNAME The hostname or IP address of the SQLServer server. If
not using a SQLServer Docker container and
corresponding link, this environment variable is
*REQUIRED*.
SQLSERVER_PORT The port on which the SQLServer server is listening for
TCP connections. This environment variable is option. If
omitted, the standard SQLServer port of 1433 will be
used.
