Utility function for specifying Kubernetes agent pools
agent_pool(name, count, size = "Standard_DS2_v2", os = "Linux", disksize = 0, use_scaleset = TRUE, low_priority = FALSE, autoscale_nodes = FALSE, ...)
name: The name(s) of the pool(s).count: The number of nodes per pool.size: The VM type (size) to use for the pool. To see a list of available VM sizes, use the list_vm_sizes method for the resource group or subscription classes.os: The operating system to use for the pool. Can be "Linux" or "Windows".disksize: The OS disk size in gigabytes for each node in the pool. A value of 0 means to use the default disk size for the VM type.use_scaleset: Whether to use a VM scaleset instead of individual VMs for this pool. A scaleset offers greater flexibility than individual VMs, and is the recommended method of creating an agent pool.low_priority: If this pool uses a scaleset, whether it should be made up of spot (low-priority) VMs. A spot VM pool is cheaper, but is subject to being evicted to make room for other, higher-priority workloads. Ignored if use_scaleset=FALSE.autoscale_nodes: The cluster autoscaling parameters for the pool. To enable autoscaling, set this to a vector of 2 numbers giving the minimum and maximum size of the agent pool. Ignored if use_scaleset=FALSE....: Other named arguments, to be used as parameters for the agent pool.An object of class agent_pool, suitable for passing to the create_aks constructor method.
agent_pool is a convenience function to simplify the task of specifying the agent pool for a Kubernetes cluster.
