nomad job revert command reference
The job revert command is used to revert a job to a prior version of the
job. The available versions to revert to can be found using job history
command.
Usage
nomad job revert [options] <job> <version|tag>
The job revert command requires two inputs: the job ID, and the version number
or tag of the job to revert to. When you specify a version number, Nomad
reverts the job to the exact version number. Alternately, when you specify a
custom tag name as a string, Nomad reverts to the version tagged with that
name.
When ACLs are enabled, this command requires a token with the submit-job
capability for the job's namespace. The list-jobs capability is required to
run the command with a job prefix instead of the exact job ID. The read-job
capability is required to monitor the resulting evaluation when -detach is
not used.
Options
-detach: Return immediately instead of monitoring. A new evaluation ID will be output, which can be used to examine the evaluation using the eval status command.-verbose: Show full information.
Examples
Revert to an older version of a job:
$ nomad job history -p example
Version = 1
Stable = false
Submit Date = 07/25/17 21:27:30 UTC
Diff =
+/- Job: "example"
+/- Task Group: "cache"
+/- Task: "redis"
+/- Config {
+/- image: "redis:7" => "redis:4.0"
port_map[0][db]: "6379"
}
Version = 0
Stable = false
Submit Date = 07/25/17 21:27:18 UTC
$ nomad job revert example 0

Evaluation triggered by job "example"
Evaluation within deployment: "e17c8592"
Allocation "4ed0ca3b" modified: node "e8a2243d", group "cache"
