This compose stack makes these containers:

• guacamole - the web front end
• guacd - the connection broker
• postgres - the database for auth
• adminer - databse admin

1. Run the stack with docker-compose up -d
2. Go to http://localhost:8081
3. Log in to the guacamole-docker_postgres_1 host with postgres/password
4. Create a database called guacamole
5. Import initdb.sql into the guacamole database
6. Log in to http://localhost:8080 with guacadmin:guacadmin
7. Change the password and/or create a new user
8. Eat cake

Replace localhost with the docker server IP if you're running it somewhere else.

Not much for me to offer, you're better off looking at guacamole's docs, but feel free to tweet me @TerminalOutcome if you think I can help.
