Command: sentinel apply

The sentinel apply command is used to write a new, or update an existing, Sentinel policy.

Sentinel commands are only available with Nomad Enterprise.

Usage

nomad sentinel apply [options] <Policy Name> <Policy File>

The sentinel apply command requires two arguments, the policy name and the policy file. The policy file can be read from stdin by specifying "-" as the file name.

Sentinel commands are only available when ACLs are enabled. This command requires a management token.

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.

  • -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.

Apply Options

  • -description : Sets a human readable description for the policy

  • -scope : (default: submit-job) Sets the scope of the policy and when it should be enforced.

  • -level : (default: advisory) Sets the enforcement level of the policy. Must be one of advisory, soft-mandatory, hard-mandatory.

Examples

Write a policy:

$ nomad sentinel write -description "My test policy" foo test.sentinel
Successfully wrote "foo" Sentinel policy!
