// INFORMATION:
//
// This file acts as a CUE type schema for nomad JSON job submission in bitte end use repos.
// This ensures that JSON jobs created by CUE conform to Nomads JSON job spec found at:
//
// https://www.nomadproject.io/api-docs/json-jobs
//
// Not all valid Nomad JSON job options may be included here yet; this file can be extended as needed.
// If expected Nomad job properties are still not appearing in deployed jobs, check that bitte-cli
// is allowing the expected JSON through the [de]serialization parsing.
//
// In bitte end use repos, this file normally lives at:
//
// schemas/nomad/types.cue
