Command: job allocs

The job allocs command is used to display the allocations for a particular job.

Usage

nomad job allocs [options] <job>

The job allocs command requires a single argument, the job ID or an ID prefix of a job to display the list of allocations for.

When ACLs are enabled, this command requires a token with the read-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.

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 '*', subcommands which support this functionality 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.

Allocs Options

  • -all: Display all allocations matching the job ID, even those from an older instance of the job.

  • -json: Output the allocations in JSON format.

  • -t: Format and display the allocations using a Go template.

  • -verbose: Show full information.

Examples

List the allocations for a particular job:

$ nomad job allocs example
ID        Node ID   Task Group  Version  Desired  Status   Created   Modified
c2b4606d  35085106  cache       2        run      running  21s ago   10s ago
c413424b  35085106  cache       2        run      pending  1m8s ago  11s ago

Verbose listing of allocations for a particular job:

$ nomad job allocs -verbose example
ID                                    Eval ID                               Node ID                               Node Name  Task Group  Version  Desired  Status   Created                    Modified

Format job allocations using a Go template:

$ nomad job allocs -t '{{ range . }}{{ println .ID }}{{ end }}' example
c2b4606d-1b02-0d8d-5fdd-031167cd4c91
c413424b-d80e-9bc6-ea92-a02b336eaaf5

Use a Go template to filter only allocations which are running

$ nomad job allocs -t '{{ range . }}{{ if eq .ClientStatus "running" }}{{ println .ID }}{{ end }}{{ end }}' example
c2b4606d-1b02-0d8d-5fdd-031167cd4c91
