Nomad

Nomad is HashiCorp's CLI for operating Nomad clusters and the workloads they schedule. It covers job submission, dry runs, node and allocation inspection, service discovery, variables, and cluster-level operator tasks from one command surface.

• Plan, submit, inspect, scale, dispatch, and stop jobs, with dry-run diffs before rollout and guarded updates via check-index.
• Inspect nodes, allocations, and registered services, read allocation files, and exec into running tasks for debugging and verification.
• Operate cluster state through ACL, variable, quota, volume, autopilot, and snapshot commands without dropping to raw API calls.

• Many inspect commands expose -json or other structured output and share stable non-interactive flags, so they compose well in shell loops once cluster address and auth are configured.
• job plan plus job run -check-index gives agents a safer inspect, change, and verify path than blind job updates.
• Fit weakens around interactive monitor and exec flows, and much of the CLI only becomes useful with a reachable Nomad cluster plus the right ACL context.

• Useful automation depends on a running Nomad cluster or agent and often ACL tokens, namespaces, and other environment-specific context.
• JSON support is broad but not universal, and some commands still default to human-oriented text or interactive monitoring behavior.
