nomad job tag CLI command scaffolding

[philrenaud]

Nomad should implement a new nomad job tag command and equivalent POST /v1/job/:job_id/versions endpoint with the following capabilities:

• nomad job tag -version 3 -name "high-traffic-variant" $jobname

  • Adds the TaggedVersion object to the $jobname job at version 3, with a name of high-traffic-variant

• nomad job tag -name "burrito-promo-variant" $jobname

  • Adds the TaggedVersion object to the $jobname job at the latest version, with a name of burrito-promo-variant

• nomad job tag -D -name “low-latency-variant” $jobname

  • Finds the version of $jobname with TaggedVersion.name corresponding to low-latency-variant and deletes that TaggedVersion block, allowing the garbage collector to remove the job at next run.

• nomad job run -tag “golden” $file.nomad.hcl

  • Submits a job with the details provided in $file (say, with an id of “my-job”)
  • Adds the TaggedVersion object to the job with a name of golden (preventing future versions from rendering it garbage-collectable, and making it diff-able)
