Installing image service

Prerequisites

Ensure Customer IP is reachable to the data switch.
Ensure BIOS and NIC settings are applied on all the servers via hardware preparation.
Ensure that all servers are powered on.
Ensure that ESXi iso is present in NPS toolkit VM. The path and name of the iso must match the path and name specified for the field iso_filepath in Input JSON file.
Ensure DNS is configured with all the required hostnames and the IPs and are resolvable from the NPS VM.
Ensure that the USB drive is at the top of the server boot order.

Procedure

To bring up “image-service” pod for the installation of ESXi on all the management and resource hosts, run the following command from NPS toolkit VM.
```
nps baremetal -a install -nos <nos_type> -l debug
```
Where,

nos - is Network Operating System and the supported <nos_type> is cumulus.

NOTE:
It will take a few minutes to complete the Installation. You can verify the status of the installation by running the "show" command.
To monitor the status of the installation, run the following command on NPS toolkit VM:
```
nps show --service baremetal
```
Wait until the status is displayed as COMPLETED or SUCCESS for all the servers.
NOTE:
- For any installation issue, check the log file /var/nps/logs/<topology_name>/baremetal_install.log and take the necessary steps.
- After image service installation, ESXi host will be in maintenance mode and during image service configuration, host will be changed to normal mode.
