Good morning,
See attached for a docker-compose file that runs Guacamole 0.9.13
successfully in the following environment:
1. Docker host = Ubuntu 16.04.3 LTS
2. Docker engine = 17.06.2-ce
3. Docker compose = 1.13.0.
A note about the attached docker-compose file:
From what I understand about Docker networking, 'network_mode:
"bridge"' places docker-compose initiated containers on the default
bridge network which is handy if you want them to interact with
containers that were not initiated with docker-compose.
For example, if you use a common database container initiated via
typical docker command line instructions it would reside on the default
"bridge" network. To place your Guacamole containers on the bridge
network such that the common database container is accessible,
'network_mode: "bridge"' would be used.
Regards,
Jake

Anyone have ideas on the below? I get the same error when guacd is
running or when it’s not. I’ve tried it with docker link (deprecated)
and putting all the containers on a docker network. No matter what,
tomcat gives me the connection refused error. I tried it with RDP and
random other protocols just to see if I could generate a different
warning.
I can telnet to $GUACD_HOST 4802 from the guacamole server and see the
guacd error about the protocol in the logs. I’ve disabled windows
firewall, disabled antivirus, tried it on public and private networks
and am just flat out of ideas.

I thought I was there but think I have a problem with guacamole
connecting to guacd. From each of the containers I can ping the other
so the network connectivity within docker _/seems/_ OK. Here’s what I
have when I attempt to connect to a connection that I setup through
the GUI:
01:42:10.038 [http-nio-8080-exec-1] ERROR
o.a.g.w.GuacamoleWebSocketTunnelEndpoint - Creation of WebSocket
tunnel to guacd failed: java.net.ConnectException: Connection refused

o.a.g.s.GuacamoleHTTPTunnelServlet - HTTP tunnel request failed:

Any tips on this one? I saw an error like this in the board history
but the person said they didn’t have guacd running. I know it’s
running but perhaps there’s a connectivity issue…
Thank you
-Ryan

Docker on win10 pro does, and that was a good idea. I had the
password environment variable wrong and saw the access denied for the
user in the mysql logs. Thanks for the quick responses!

I am running guacamole via docker on win10 pro. I’m using Mysql,
guacamole and guacd and all appear to be running as intended. I
get a 500 error when I hit the home page. Localhost access log
shows all the GETs work
Those GETs are probably to static files, and thus aren't hitting the
component which is failing.
and a PUT failed (172.17.0.1 - - [04/Oct/2017:03:27:52 +0000]
There shouldn't be a PUT occurring prior to login. What URL is that
PUT request for?
"POST /guacamole/api/tokens HTTP/1.1" 500 185). Any ideas where I
should be looking to narrow this down or get more info?
".../api/tokens" is the URL of the REST endpoint used for handling
authentication. Given the description of your setup, the MySQL portion
of things is most likely misconfigured (somehow). Once we find the
proper log, things should clear up.
Catalina error seems to be in non-guacamole classes so not sure
where to go next.
