The available versions to revert to can be found using [`job history`](/docs/commands/job/history.html) command. The revert command will use a vault token with the following preference: first the `-vault-token` flag, then the `$VAULT_TOKEN` environment variable. Because the vault token used to [run](/docs/commands/job/run.html) the targeted job version was not persisted, it must be provided to revert if the targeted job version includes Vault policies and the Nomad servers were [configured](/docs/configuration/vault.html#allow_unauthenticated) to require authentication. ## Usage ``` nomad job revert [options] ``` The `job revert` command requires two inputs, the job ID and the version of that job to revert to. ## General Options <%= partial "docs/commands/_general_options" %> ## Revert 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](/docs/commands/eval-status.html) command * `-vault-token`: If set, the passed Vault token is sent along with the revert request to the Nomad servers. This overrides the token found in the $VAULT_TOKEN environment variable. * `-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:3.2" => "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 ==> Monitoring evaluation "faff5c30" Evaluation triggered by job "example" Evaluation within deployment: "e17c8592" Allocation "4ed0ca3b" modified: node "e8a2243d", group "cache" Evaluation status changed: "pending" -> "complete" ==> Evaluation "faff5c30" finished with status "complete" $ nomad job history -p example Version = 2 Stable = true Submit Date = 07/25/17 21:27:43 UTC Diff = +/- Job: "example" +/- Task Group: "cache" +/- Task: "redis" +/- Config { +/- image: "redis:4.0" => "redis:3.2" port_map[0][db]: "6379" } Version = 1 Stable = false Submit Date = 07/25/17 21:27:30 UTC Diff = +/- Job: "example" +/- Task Group: "cache" +/- Task: "redis" +/- Config { +/- image: "redis:3.2" => "redis:4.0" port_map[0][db]: "6379" } Version = 0 Stable = false Submit Date = 07/25/17 21:27:18 UTC ```
