| distro | no | Select Master(s) Operating System (Linux only). Currently supported values are: `ubuntu`, `aks` and `coreos` (CoreOS support is currently experimental). Defaults to `aks` if undefined. `aks` is a custom image based on `ubuntu` that comes with pre-installed software necessary for Kubernetes deployments (Azure Public Cloud only for now). Currently supported OS and orchestrator configurations -- `ubuntu` and `aks`: DCOS, Docker Swarm, Kubernetes; `RHEL`: OpenShift; `coreos`: Kubernetes. [Example of CoreOS Master with CoreOS Agents](../examples/coreos/kubernetes-coreos.json) |

| distro | no | Specifies the masters' Linux distribution. Currently supported values are: `ubuntu`, `aks`, `aks-docker-engine` and `coreos` (CoreOS support is currently experimental - [Example of CoreOS Master with CoreOS Agents](../examples/coreos/kubernetes-coreos.json)). For Azure Public Cloud, defaults to `aks` if undefined, unless GPU nodes are present, in which case it will default to `aks-docker-engine`. For Sovereign Clouds, the default is `ubuntu`. `aks` is a custom image based on `ubuntu` that comes with pre-installed software necessary for Kubernetes deployments (Azure Public Cloud only for now). **NOTE**: GPU nodes are currently incompatible with the default Moby container runtime provided in the `aks` image. Clusters containing GPU nodes will be set to use the `aks-docker-engine` distro which is functionally equivalent to `aks` with the exception of the docker distribution (see [GPU support Walkthrough](kubernetes/gpu.md) for details).

| customFiles | no | The custom files to be provisioned to the master nodes. Defined as an array of json objects with each defined as `"source":"absolute-local-path", "dest":"absolute-path-on-masternodes"`.[See examples](../examples/customfiles) |
|
||||
| availabilityProfile | no | Supported values are `AvailabilitySet` (default) and `VirtualMachineScaleSets` (still under development: upgrade not supported; requires Kubernetes clusters version 1.10+ and agent pool availabilityProfile must also be `VirtualMachineScaleSets`). When MasterProfile is using `VirtualMachineScaleSets`, to SSH into a master node, you need to use `ssh -p 50001` instead of port 22. |
|
||||
| agentVnetSubnetId | only required when using custom VNET and when MasterProfile is using `VirtualMachineScaleSets` | Specifies the Id of an alternate VNET subnet for all the agent pool nodes. The subnet id must specify a valid VNET ID owned by the same subscription. ([bring your own VNET examples](../examples/vnet)). When MasterProfile is using `VirtualMachineScaleSets`, this value should be the subnetId of the subnet for all agent pool nodes. |
