Appliance Mode
In appliance mode, you bring your own host, which can be either a VM in VMware vCenter or an Edge host in a remote location. Unlike agent mode, instead of having to manage your own Operating Systems (OS), you would build secure, immutable images that combine the OS and the Kubernetes distribution for your host cluster.
To create a cluster in appliance mode, you need to have a host that meets the minimal hardware requirement. You then need to create two artifacts: an installer ISO file and a provider image. The installer ISO will include an OS of a supported distribution, with the Palette agent natively installed. The provider image is an image that combines the OS and the Kubernetes layer for your cluster.
Depending on your business needs, you can deploy centrally managed or locally managed clusters in appliance mode. If you deploy a centrally managed cluster, your hosts will register with Palette based on the registration token you provide during the installer build. Once registered, you can use the hosts as control plane or worker nodes to create a cluster. Alternatively, you can use Local UI to create a locally managed cluster, which does not require a connection to Palette.
