Command: var get

The var get command is used to get the contents of an existing variable.

Usage

nomad var get [options] <path>

If ACLs are enabled, this command requires a token with the variables:read capability for the target variable's namespace and path. See the ACL policy documentation for details.

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.

Output Options

  • -item (string: ""): Print only the value of the given item. Specifying this option will take precedence over other formatting directives. The result will not have a trailing newline making it ideal for piping to other processes.

  • -out (enum: go-template | hcl | json | none | table ): 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".

Examples

Retrieve the variable stored at path "secret/creds":

$ nomad var get secret/creds
Namespace   = default
Path        = secret/creds
Create Time = 2022-08-23T11:14:37-04:00
Check Index = 116

Items
passcode = my-long-passcode

Return only the "passcode" item from the variable stored at "secret/creds":

$ nomad var get -item=passcode secret/creds
my-long-passcode
