Command: recommendation list

The recommendation list command is used to list the available recommendations.

Usage

nomad recommendation list [options]

The recommendation list command requires no arguments.

When ACLs are enabled, this command requires a token with the submit-job, read-job, and submit-recommendation capabilities for the namespace being queried.

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 namespacecs authorized to user. Defaults to the "default" namespace.

• -no-color: Disables colored command output. Alternatively, NOMAD_CLI_NO_COLOR may be set.

• -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.

List Options

• -job: Specifies the job ID to filter the recommendations list by.

• -group: Specifies the task group name to filter within a job. If specified, the -job flag must also be specified.

• -task: Specifies the task name to filter within a job and task group. If specified, the -job and -group flags must also be specified.

• -json: Output the recommendations in its JSON format.

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