Command: nomad tls ca create

Create is used to create a self signed Certificate Authority to be used for Nomad TLS setup.

Usage

nomad tls ca create [options]

CA Create Options

-additional-domain=<value>: Add name constraints for the CA. The server will reject certificates for DNS names other than those specified in -domain and -additional-domain. Can be used multiple times. This option can only used in combination with -domain and -name-constraint.
common-name: Common Name of CA. Defaults to Nomad Agent CA.
-days=<int>: Provide number of days the CA is valid for from now on, defaults to 5 years.
-domain=<string>: Domain of nomad cluster. Only used in combination with -name-constraint. Defaults to nomad.
-name-constraint: Add name constraints for the CA. Results in rejecting certificates for other DNS than specified. If set to true, "localhost" and -domain will be added to the allowed DNS. Defaults to false.

Warning: If -name-constraint is enabled and you intend to serve the Nomad web UI over HTTPS its DNS must be added with additional-domain. It is not possible to add that after the fact.

Example

Create CA:

$ nomad tls ca create
==> CA Certificate saved to: nomad-agent-ca.pem
==> CA Certificate key saved to: nomad-agent-ca-key.pem

Create a CA with a specified domain:

$ nomad tls ca create -name-constraint="true" -domain="foo.com"
==> CA Certificate saved to: foo.com-agent-ca.pem
==> CA Certificate key saved to: foo.com-agent-ca-key.pem
