--- layout: docs page_title: 'Commands: job revert' description: | The revert command is used to revert to a prior version of the job. --- # Command: job revert 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. The revert command will use a Consul token with the following preference: first the `-consul-token` flag, then the `$CONSUL_HTTP_TOKEN` environment variable. Because the consul token used to [run] the targeted job version was not persisted, it must be provided to revert if the targeted job version includes Consul Connect enabled services and the Nomad servers were configured to require [consul service identity] authentication. The revert command will use a Vault token with the following preference: first the `-vault-token` flag, then the `$VAULT_TOKEN` environment variable. Because the vault token used to [run] 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 to require [vault policy] authentication. ## Usage ```plaintext nomad job revert [options] ``` The `job revert` command requires two inputs, the job ID and the version of that job to revert to. When ACLs are enabled, this command requires a token with the `submit-job` and `list-jobs` capabilities for the job's namespace. ## General Options @include 'general_options.mdx' ## 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] command. - `-consul-token`: If set, the passed Consul token is sent along with the revert request to the Nomad servers. This overrides the token found in the `$CONSUL_HTTP_TOKEN` environment variable. - `-vault-token`: If set, the passed Vault token is sent along with the revert request to the Nomad servers. This overrides the token found in the `$VAULT_TOKEN` environment variable. - `-verbose`: Show full information. ## Examples Revert to an older version of a job: ```shell-session $ 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 ``` [`job history`]: /docs/commands/job/history [eval status]: /docs/commands/eval-status [consul service identity]: /docs/configuration/consul#allow_unauthenticated [vault policy]: /docs/configuration/vault#allow_unauthenticated [run]: /docs/commands/job/run
