## Matchers
|
|
|
|
This Chef InSpec audit resource has the following special matchers. For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
|
|
|
|
### be\_pending
|
|
|
|
The `be_pending` matcher tests if the described EC2 instance state is `pending`. This indicates that an instance is provisioning. This state should be temporary.
|
|
|
|
it { should be_pending }
|
|
|
|
### be\_running
|
|
|
|
The `be_running` matcher tests if the described EC2 instance state is `running`. This indicates the instance is fully operational from AWS's perspective.
|
|
|
|
it { should be_running }
|
|
|
|
### be\_shutting\_down
|
|
|
|
The `be_shutting_down` matcher tests if the described EC2 instance state is `shutting-down`. This indicates the instance has received a termination command and is in the process of being permanently halted and de-provisioned. This state should be temporary.
|
|
|
|
it { should be_shutting_down }
|
|
|
|
### be\_stopped
|
|
|
|
The `be_stopped` matcher tests if the described EC2 instance state is `stopped`. This indicates that the instance is suspended and may be started again.
|
|
|
|
it { should be_stopped }
|
|
|
|
### be\_stopping
|
|
|
|
The `be_stopping` matcher tests if the described EC2 instance state is `stopping`. This indicates that an AWS stop command has been issued, which will suspend the instance in an OS-unaware manner. This state should be temporary.
|
|
|
|
it { should be_stopping }
|
|
|
|
### be\_terminated
|
|
|
|
The `be_terminated` matcher tests if the described EC2 instance state is `terminated`. This indicates the instance is permanently halted and will be removed from the instance listing in a short period. This state should be temporary.
|
|
|
|
it { should be_terminated }
|
|
|
|
### be\_unknown
|
|
|
|
The `be_unknown` matcher tests if the described EC2 instance state is `unknown`. This indicates an error condition in the AWS management system. This state should be temporary.
|
|
|
|
it { should be_unknown }
|
|
|
|
