Subject Re: tracking down a tomcat 500 error
Date Fri, 06 Oct 2017 12:02:20 GMT
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
