%description
    Nomad is a cluster manager, designed for both long lived services
    and short lived batch processing workloads. Developers use a
    declarative job specification to submit work, and Nomad ensures
    constraints are satisfied and resource utilization is optimized by
    efficient task packing. Nomad supports all major operating systems
    and virtualized, containerized, or standalone applications.
