HashiCorp Nomad Scheduler AI Skill Guide (Claude)

Overview & Engine Architecture

Nomad schedules jobs → task groups → tasks onto a client fleet using drivers (Docker, exec, Java, etc.). Servers evaluate and place allocations; clients start tasks. Compared to Kubernetes, jobspecs are compact HCL and commonly pair with @consul (discovery/checks) and @vault (secrets). Prefer nomad job plan then run -check-index, digest-pinned images, and canary + auto_revert over surprise in-place restarts.
