Michael Jumper updated GUACAMOLE-824:
-------------------------------------
Description:
Hi,
Can anyone see what I'm doing wrong here? It appears to be ignoring the
GUACAMOLE_HOME variable.
I have tried using both the version from Docker Hub and the one from Github.
If I add the -e GUACD_HOSTNAME and -e GUACD_PORT, I no longer get the error,
but the Docker logs show the home is "/root/.guacamole"
{code:none}

FATAL: Missing GUACD_HOSTNAME or "guacd" link.
-------------------------------------------------------------------------------
Every Guacamole instance needs a corresponding copy of guacd running. To
provide this, you must either:
(a) Explicitly link that container with the link named "guacd".
(b) If not using a Docker container for guacd, explicitly specify the TCP
connection information using the following environment variables:
GUACD_HOSTNAME The hostname or IP address of guacd. If not using a guacd
Docker container and corresponding link, this environment
variable is *REQUIRED*.
GUACD_PORT The port on which guacd is listening for TCP connections.
This environment variable is optional. If omitted, the
standard guacd port of 4822 will be used.

> FATAL: Missing GUACD_HOSTNAME or "guacd" link.
> -------------------------------------------------------------------------------
> Every Guacamole instance needs a corresponding copy of guacd running. To
> provide this, you must either:
> (a) Explicitly link that container with the link named "guacd".
> (b) If not using a Docker container for guacd, explicitly specify the TCP
> connection information using the following environment variables:
> GUACD_HOSTNAME The hostname or IP address of guacd. If not using a guacd
> Docker container and corresponding link, this environment
> variable is *REQUIRED*.
> GUACD_PORT The port on which guacd is listening for TCP connections.
> This environment variable is optional. If omitted, the
> standard guacd port of 4822 will be used.
