How To Use the Preview Environment

What is the Globus preview environment?

Globus provides a Preview environment for previewing upcoming changes to Globus services. This allows developers and users to test their applications with the changes before the changes are released for mainstream use. Most of the time, the services in the Preview environment are the same as the normal system. When significant changes are being readied for release, we deploy them in the Preview environment for testing and announce it on the Globus User Discussion email list.

The Preview environment is isolated and completely separate from the main Globus service. User accounts, groups, endpoint registrations, and application registrations are not shared between the normal system and the Preview system. You will need to create and maintain separate accounts, groups, endpoint registrations, and application registrations for the Preview environment.

The Preview environment is available at Other service information is listed below.

Preview TCP ports

Since services will be connecting to your endpoint from the Preview environment, some additional ports must be open. (These are in addition to the normal Globus Connect Server firewall requirements.)

Port 2811 inbound from

  • Used for GridFTP control channel traffic.

Port 7512 inbound from

  • Used for MyProxy traffic.

  • This is only needed if your server is using a MyProxy service.

Using the Globus CLI

To use the Globus CLI with the Preview environment, set the GLOBUS_SDK_ENVIRONMENT environment variable to the value "preview". This tells the CLI to make API calls to the Preview environment’s services.

You will need to login again when you set this environment variable, but because the CLI manages tokens separately for each environment, you can unset the GLOBUS_SDK_ENVIRONMENT variable or use a separate terminal to go back to using the main environment without having to login again.

If you logout of one environment, it will not log you out of the other environment automatically, so be sure to logout of both environments when you are done.

For example, if you are using a bash shell, you can login to the preview environment with the following commands.

$ globus login

You can logout of both environments using the following commands.

$ globus logout
$ globus logout
