To work with the GT3 container, you'll need to ssh to the machine that you want to work with as user globus. If you haven't already done so, set up the environment for user globus as described in Section 1.1. To start the container run the following:
globus-start-container [-p port-number]
The last argument is optional. If you don't specify a port number, the container will start up on port 8080. If you experience problems working with the container you started, one of the first things to try is to start it on a port other than 80801.
When started, the container should print to standard output a list of url's pointing to all of the grid services that it is now running. If you've just deployed a new grid services, you'll want to check this list and make sure that your service is listed. If not, you will probably need to redeploy your service.
