Nomad
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

- -no-color: Disables colored command output. Alternatively,- NOMAD_CLI_NO_COLORmay be set. This option takes precedence over- -force-color.
- -force-color: Forces colored command output. This can be used in cases where the usual terminal detection fails. Alternatively,- NOMAD_CLI_FORCE_COLORmay be set. This option has no effect if- -no-coloris also used.
- -ca-cert=<path>: Path to a PEM encoded CA cert file to use to verify the Nomad server SSL certificate. Overrides the- NOMAD_CACERTenvironment variable if set.
- -ca-path=<path>: Path to a directory of PEM encoded CA cert files to verify the Nomad server SSL certificate. If both- -ca-certand- -ca-pathare specified,- -ca-certis used. Overrides the- NOMAD_CAPATHenvironment variable if set.
- -client-cert=<path>: Path to a PEM encoded client certificate for TLS authentication to the Nomad server. Must also specify- -client-key. Overrides the- NOMAD_CLIENT_CERTenvironment variable if set.
- -client-key=<path>: Path to an unencrypted PEM encoded private key matching the client certificate from- -client-cert. Overrides the- NOMAD_CLIENT_KEYenvironment variable if set.
- -tls-server-name=<value>: The server name to use as the SNI host when connecting via TLS. Overrides the- NOMAD_TLS_SERVER_NAMEenvironment variable if set.
