nomad var list command reference

The var list command returns a list of variable paths accessible to the current user, optionally filtered to paths containing a provided prefix. Do not encode sensitive information in variable paths. The variable's items are not accessible via this command.

When using pagination, the next page token is provided as part of the output of the command. When the output format is JSON, the returned variable list is wrapped with additional metadata that contains the next page token. For non-JSON output, the next page token is printed as a message to standard error and standard output contains the variables from the specifically requested page.

Usage

nomad var list [options] [<prefix>]

If ACLs are enabled, this command requires the variables:list capability for the namespaces and paths containing the variables to list. See the ACL policy documentation for details.

Options

-per-page (int: <unset>): How many results to show per page.
-page-token (string: ""): Where to start pagination.
-filter (string: ""): Specifies an expression used to filter query results. Queries using this option are less efficient than using the prefix parameter; therefore, the prefix parameter should be used whenever possible.
-out (enum: go-template | json | table | terse ): Format to render the variable in. When using "go-template", you must provide the template content with the -template option. Defaults to "table" when stdout is a terminal and to "json" when stdout is redirected.
-template (string: "") Template to render output with. Required when output is "go-template".
-ui: Open the variable list page in the browser.

Examples

default    nomad/jobs/variable/www/nginx  2022-08-23T10:24:46-04:00

List values under the key "nomad/jobs/variable/www" in JSON format:

$ nomad var list -out=json -namespace="*" nomad/jobs/variable/www
[
  {
    "Namespace": "default",
    "Path": "nomad/jobs/variable/www",
    "CreateIndex": 1457,
    "ModifyIndex": 1457,
    "CreateTime": 1662061225600373000,

Perform a paginated query:

$ nomad var list -per-page=3
Namespace  Path                           Last Updated
default    nomad/jobs/example             2022-08-23T10:35:47-04:00
default    nomad/jobs/variable            2022-08-23T10:24:45-04:00
default    nomad/jobs/variable/www        2022-08-23T10:24:45-04:00
Next page token: default.nomad/jobs/variable/www/nginx

To fetch the next page :

$ nomad var list -per-page=3 \
  -page-token=default.nomad/jobs/variable/www/nginx
Namespace  Path                 Last Updated
default    nomad/jobs/variable/www/nginx  2022-08-23T10:24:46-04:00

Perform a paginated query with JSON formatting:

$ nomad var list -out=json -namespace="*" -per-page=1 nomad/jobs/variable/www
{
    "Data": [
        {
           "Namespace": "default",
            "Path": "nomad/jobs/variable/www",
            "CreateIndex": 1457,
            "ModifyIndex": 1457,
            "CreateTime": 1662061225600373000,
            "ModifyTime": 1662061225600373000
        }
    ],
    "QueryMeta": {
        "KnownLeader": true,
        "LastContact": 0,
        "LastIndex": 43,
        "NextToken": "default.nomad/jobs/variable/www/nginx",
        "RequestTime": 875792
    }
}

As with the tabular version, provide the QueryMeta.NextToken value as the -page-token value to fetch the next page.

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.
