»Command: alloc restart

The alloc restart command allows a user to perform an in place restart of an an entire allocation or individual task.

»Usage

nomad alloc restart [options] <allocation> <task>
nomad alloc restart [options] <allocation> <task>

This command accepts a single allocation ID and a task name. The task name must be part of the allocation and the task must be currently running. The task name is optional and if omitted every task in the allocation will be restarted.

Task name may also be specified using the -task option rather than a command argument. If task name is given with both an argument and the -task option, preference is given to the -task option.

When ACLs are enabled, this command requires a token with the alloc-lifecycle, read-job, and list-jobs capabilities for the allocation's namespace.

»General Options

  • -address=<addr>: The address of the Nomad server. Overrides the NOMAD_ADDR environment variable if set. Defaults to http://127.0.0.1:4646.

  • -region=<region>: The region of the Nomad server to forward commands to. Overrides the NOMAD_REGION environment variable if set. Defaults to the Agent's local region.

  • -namespace=<namespace>: The target namespace for queries and actions bound to a namespace. Overrides the NOMAD_NAMESPACE environment variable if set. If set to '*', job and alloc subcommands query all namespaces authorized to user. Defaults to the "default" namespace.

  • -no-color: Disables colored command output. Alternatively, NOMAD_CLI_NO_COLOR may 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_COLOR may be set. This option has no effect if -no-color is 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_CACERT environment 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-cert and -ca-path are specified, -ca-cert is used. Overrides the NOMAD_CAPATH environment 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_CERT environment 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_KEY environment 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_NAME environment variable if set.

  • -tls-skip-verify: Do not verify TLS certificate. This is highly not recommended. Verification will also be skipped if NOMAD_SKIP_VERIFY is set.

  • -token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the NOMAD_TOKEN environment variable if set.

»Restart Options

  • -task: Specify the individual task to restart.

  • -verbose: Display verbose output.

»Examples

$ nomad alloc restart eb17e557

$ nomad alloc restart eb17e557 foo
Could not find task named: foo, found:
* test
<blocking>
$ nomad alloc restart eb17e557

$ nomad alloc restart eb17e557 foo
Could not find task named: foo, found:
* test
<blocking>

Specifying task name with the -task option:

$ nomad alloc restart -task redis eb17e557
$ nomad alloc restart -task redis eb17e557

If task name is specified using both options, the command argument is ignored. The following will restart the "redis" task only, not the "api" task:

$ nomad alloc restart -task redis eb17e557 api
$ nomad alloc restart -task redis eb17e557 api
