# Consul-Terraform-Sync Enterprise License
|
|
|
|
<EnterpriseAlert>
|
|
Licenses are only required for Consul-Terraform-Sync (CTS) Enterprise
|
|
</EnterpriseAlert>
|
|
|
|
CTS Enterprise binaries require a [Consul Enterprise license](/docs/enterprise/license/overview) to run. There is no CTS Enterprise specific license. As a result, CTS Enterprise's licensing is very similar to Consul Enterprise.
|
|
|
|
All CTS Enterprise features are available with a valid Consul Enterprise license, regardless of your Consul Enterprise packaging or pricing model.
|
|
|
|
To get a trial license for CTS, you can sign-up for the [trial license for Consul Enterprise](/docs/enterprise/license/faq#q-where-can-users-get-a-trial-license-for-consul-enterprise).
|
|
|
|
## Setting the License
|
|
|
|
Choose one of the following methods (in order of precedence) to set the license:
|
|
|
|
1. Set the `CONSUL_LICENSE` environment variable to the license string.
|
|
|
|
```shell-session
|
|
export CONSUL_LICENSE=<LICENSE_VALUE>
|
|
```
|
|
|
|
1. Set the `CONSUL_LICENSE_PATH` environment variable to the path of the file containing the license.
|
|
|
|
```shell-session
|
|
export CONSUL_LICENSE_PATH=<PATH>/<TO>/<FILE>
|
|
```
|
|
|
|
1. Configure the [`license_path`](/docs/nia/configuration#license_path) option in the configuration file to point to the file containing the license.
|
|
|
|
```hcl
|
|
license_path = "<PATH>/<TO>/<FILE>"
|
|
```
|
|
|
|
~> **Note**: the [options to set the license and the order of precedence](/docs/enterprise/license/overview#binaries-without-built-in-licenses) are the same as Consul Enterprise server agents.
|
|
Visit the [Enterprise License Tutorial](https://learn.hashicorp.com/tutorials/nomad/hashicorp-enterprise-license?in=consul/enterprise) for detailed steps on how to install the license key.

### Updating the License
|
|
|
|
The previous section describes options for [setting the license](#setting-the-license) needed to start running CTS Enterprise. Use the following procedure to update the license when it expires or is near the expiration date:
|
|
|
|
1. Update the license environment variable or configuration with the new license value or path to the new license file
|
|
1. Stop and restart CTS Enterprise
|
|
|
|
Once CTS Enterprise starts again, it will pick up the new license and run the tasks with any changes that may have occurred between the stop and restart period.
|
|
|
|
## Notification and Termination Behavior
|
|
|
|
Licenses have an expiration date and a termination date. The termination date is a time at or after the license expires. CTS Enterprise will cease to function once the termination date has passed.
|
|
|
|
The time between the expiration and termination dates is a grace period. Grace periods are generally 24-hours, but you should refer to your license agreement for complete terms of your grace period.
|
|
|
|
When approaching expiration and termination, CTS Enterprise will provide notifications in the system logs:
|
|
|
|
| Time period | Behavior |
|
|
| ------------------------------------------- | --------------------------------- |
|
|
| 30 days before expiration | Warning-level log every 24-hours |
|
|
| 7 days before expiration | Warning-level log every 1 hour |
|
|
| 1 hour before expiration | Warning-level log every 1 minute |
|
|
| 1 day before expiration | Warning-level log every 5 minutes |
|
|
| At or after expiration (before termination) | Error-level log every 1 minute |
|
|
| At or after termination | Error-level log and exit |
|
|
|
|
~> **Note**: Notification frequency and [grace period](/docs/enterprise/license/faq#q-is-there-a-grace-period-when-licenses-expire) behavior is the same as Consul Enterprise.
