Setting an Affinity for a Nomad Job in a Cluster
There are times when you want your Nomad jobs to be sent to specific locations. For instance, you may want a percentage of the jobs to be run in a separate datacenter. In this lab, you are tasked with creating a job file and adjusting it so that it prefers to be in a different datacenter. You have been provided with a Nomad cluster that has two client nodes. The tasks you will perform in this hands-on lab will be performed on the provided Nomad server. The Nomad server has been configured with one server agent and two client agents. Docker has been installed so that Nomad is ready to run jobs.
