Make a VM cluster suitable for running parallel workloads

This wraps the commands for creating a cluster suitable for future workloads.

gce_vm_cluster(vm_prefix = "r-cluster-", cluster_size = 3,
  docker_image = "rocker/r-parallel", ..., ssh_args = NULL,
  project = gce_get_global_project(), zone = gce_get_global_zone())

Arguments

vm_prefix	The prefix of the VMs you want to make. Will be appended the cluster number
cluster_size	The number of VMs in your cluster
docker_image	The docker image the jobs on the cluster will run on. Recommend this is derived from rocker/r-parallel
...	Passed to gce_vm_template
ssh_args	A list of optional arguments that will be passed to gce_ssh_setup
project	The project to launch the cluster in
zone	The zone to launch the cluster in

Examples

if (FALSE) {
library(future)
library(googleComputeEngineR)

vms <- gce_vm_cluster()

## make a future cluster
plan(cluster, workers = as.cluster(vms))

}
