Using Spread Job Placement for a Nomad Job in a Cluster
In this lab, we will be creating a job in Nomad that runs 10 allocations. We will set this up in such a way that 70% of the allocations will go to one location and 30% of allocations will go to another. To accomplish this, we will use spread job placement to spread the jobs around our cluster.
