If the SSH user configured in the on-premises provider has sudo privileges that require a password, you can provision your nodes by running the pre-provisioning script (provision_instance.py).

The script is displayed under Instances on the Instances tab of the on-prem configuration you created.

Manually provision nodes using the script

You can manually provision each node using the pre-provisioning Python script, as follows:

1. Log in to the YBA virtual machine via SSH.

2. If you installed YBA using Replicated, access the Docker yugaware container, as follows:

   sudo docker exec -it yugaware bash
   

3. In YBA, navigate to Configs > Infrastructure > On-Premises Datacenters, select the on-premises provider configuration you created, and choose Instances.

   

4. Copy and paste the Python script command under Instances.

   Set the flags for the command as follows:

   • --ask_password - this flag instructs the script to prompt for a password, which is required if the sudo user requires password authentication.
   • --ip - enter the IP address of the node.
   • --mount_points - enter the mount point configured for the node (typically /data). If you have multiple drives, add these as a comma-separated list, such as, for example, /mnt/d0,/mnt/d1.
   • --install_node_agent - this flag instructs the script to install the node agent, which is required for YBA to communicate with the instance.
   • --api_token - enter your API token; you can create an API token by navigating to your User Profile and clicking Generate Key.
   • --yba_url - enter the URL of the machine where you are running YBA, with port 9000. For example, http://ybahost.company.com:9000. The node must be able to communicate with YBA at this address.
   • --node_name - enter a name for the node.
   • --instance_type - enter the name of the instance type to use for the node. The name must match the name of an existing instance type.
   • --zone_name - enter a zone name for the node.

   For example:

   /opt/yugabyte/yugaware/data/provision/9cf26f3b-4c7c-451a-880d-593f2f76efce/provision_instance.py \
       --ask_password \
       --ip 10.9.116.65 \
       --mount_points /data \
       --install_node_agent \
       --api_token 999bc9db-ddfb-9fec-a33d-4f8f9fd88db7 \
       --yba_url http://10.98.0.40:9000 \
       --node_name onprem_node1 \
       --instance_type c5.large \
       --zone_name us-west-2a 
   

   Expect the following output and password prompt:

   Executing provision now for instance with IP 10.9.116.65...
   SUDO password:
   

5. Enter your password.

6. Wait for the script to finish successfully.

7. Repeat steps 4-6 for every node that will participate in the on-prem configuration.

After you have provisioned the nodes, you can proceed to add instances to the on-premises provider.
