Hashicorp Nomad: resources

在Kubernets的 Quality of Service for Pods裡, 根據cpu, memory的request與limit, 可以區分為Guaranteed, Burstable, BestEffort三種類型，但在Nomad v1.1 之前cpu,memory設定只有require一種，很高興看到在v1.1 Bate, 新增了兩個參數，分別是cores與memory_max, 這讓Nomad在做scheduler時增加資源的利用率。

參數說明

• cpu: The CPU required to run this task in MHz.
• cores: The number of CPU cores to reserve for the task.
• memory: The memory required in MB.
• memory_max: The maximum memory the task may use, if the client has excess memory capacity.
