For installation on bare metal (64-bit Intel/AMD CPU) an installer image can be
created in SmartWorks Studio. This installer image can be used for all assets of the
fleet.
The image contains the OS, K3s and scripts to create a new cluster on the cloud and
install the ECP Management Service at first boot. Each new asset of the fleet will
automatically show up in Studio.
The installer image needs the Client ID and Client Secret of an App (see Apps) with the "cluster" scope. It is
recommended to create a new App specifically for this purpose. Figure 1.
Follow the steps below to create a new installer image.
From the menu on the left, click Edge Ops > Images.
Click Add in the upper right corner.
Select the desired software option from the dropdown, fill in the public SSh
key(s) (each on a new line) for local access to the cluster (username: Altair)
and add the fleet identifier. If an existing fleet identifier is reused any
asset flashed from this installer image will be added to that fleet.
Figure 2.
Once the installer image has been created (this takes a few minutes) it
will be available to download.
Use either the pre-installed "disk imaging" utility on your computer or
download balenaEtcher to flash the downloaded image onto a USB drive (minimum
size 2GB).
Note: The USB drive should now be used to boot the asset (gateway) from.
When the installation process finishes the gateway will power off. An 8
character password for local SSH access is randomly generated and saved to the
/root/crypt_passwords.txt file on the USB drive. This
can be used in addition to the SSH key.
Power on the gateway to bring the asset online in Studio.
Software Update
When a software update becomes available for an asset created from an installer
image, it will be shown on the Edge Ops > Fleet Management > AssetOverview and Details panes.
Clicking the Update Now button will install the update. Note
that this process can take up to 15 minutes for large OS updates. Figure 3.
