An option is available to expose UAI ports to the customer user network in addition to the the port used for SSH access. These ports are restricted to ports 80, 443, and 8888. This procedure allows a user or administrator to create a new UAI with these additional ports.
A public SSH key
Only ports 80, 443, and 8888 can be exposed. Attempting to open any other ports will result in an error.
Log in to a UAN.
Create a new UAI with the --ports option.
ncn-w001# cray uas create --publickey PUBLIC_SSH_KEY_FILE --ports PORT_LIST
Troubleshooting: If the Cray CLI has not been initialized, the CLI commands will not work. See Configure the Cray Command Line Interface (cray CLI) for more information.
When these ports are exposed in the UAI, they will be mapped to unique ports on the UAI IP address. The mapping of these ports is displayed in the uai_portmap element of the return output from cray uas create, cray uas describe, and cray uas uais list. The mapping is shown as a dictionary where the key is the port requested and the value is the port that key is mapped to.
ncn-w001# cray uas create --publickey /root/.ssh/id_rsa.pub --ports 80,443
