azure_attributes(
  first_on_demand = 1,
  availability = c("SPOT_WITH_FALLBACK", "SPOT", "ON_DEMAND"),
  spot_bid_max_price = -1
)

first_on_demand: Number of nodes of the cluster that will be placed on on-demand instances. If this value is greater than 0, the cluster driver node will be placed on an on-demand instance. If this value is greater than or equal to the current cluster size, all nodes will be placed on on-demand instances. If this value is less than the current cluster size, first_on_demand nodes will be placed on on-demand instances and the remainder will be placed on availability instances. This value does not affect cluster size and cannot be mutated over the lifetime of a cluster.
availability: One of SPOT_WITH_FALLBACK, SPOT, ON_DEMAND. Type used for all subsequent nodes past the first_on_demand ones. If first_on_demand is zero, this availability type will be used for the entire cluster.
spot_bid_max_price: The max bid price used for Azure spot instances. You can set this to greater than or equal to the current spot price. You can also set this to -1 (the default), which specifies that the instance cannot be evicted on the basis of price. The price for the instance will be the current price for spot instances or the price for a standard instance. You can view historical pricing and eviction rates in the Azure portal.
