# host
|
|
|
|
Use the `host` InSpec audit resource to test the name used to refer to a specific host and its availability, including the Internet protocols and ports over which that host name should be available.
|
|
|
|
## Syntax
|
|
|
|
A `host` resource block declares a host name, and then (depending on what is to be tested) a port and/or a protocol:
|
|
|
|
.. code-block:: ruby
|
|
|
|
describe host('example.com', port: 80, proto: 'tcp') do
|
|
it { should be_reachable }
|
|
end
|
|
|
|
where
|
|
|
|
* `host()` must specify a host name and may specify a port number and/or a protocol
|
|
* `'example.com'` is the host name
|
|
* `port:` is the port number
|
|
* `proto: 'name'` is the Internet protocol: TCP (`proto: 'tcp'`), UDP (`proto: 'udp'` or ICMP (`proto: 'icmp'`))
|
|
* `be_reachable` is a valid matcher for this resource
|
|
|
|
|
|
## Matchers
|
|
|
|
This InSpec audit resource has the following matchers:
|
|
|
|
### be
|
|
|
|
<%= partial "/shared/matcher_be" %>
|
|
|
|
### be_reachable
|
|
|
|
The `be_reachable` matcher tests if the host name is available:
|
|
|
|
it { should be_reachable }
|
|
|
|
### be_resolvable
|
|
|
|
The `be_resolvable` matcher tests for host name resolution, i.e. "resolvable to an IP address":
|
|
|
|
it { should be_resolvable }
|
|
|
|
### cmp
|
|
|
|
<%= partial "/shared/matcher_cmp" %>
|
|
|
|
### eq
|
|
|
|
<%= partial "/shared/matcher_eq" %>
|
|
|
|
### include
|
|
|
|
<%= partial "/shared/matcher_include" %>
|
|
|
|
### ipaddress
|
|
|
|
The `ipaddress` matcher tests if a host name is resolvable to a specific IP address:
|
|
|
|
its('ipaddress') { should include '93.184.216.34' }
|
|
|
|
### match
|
|
|
|
<%= partial "/shared/matcher_match" %>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this InSpec audit resource.
|
|
|
|
### Verify host name is reachable over a specific protocol and port number
|
|
|
|
describe host('example.com', port: 53, proto: 'udp') do
|
|
it { should be_reachable }
|
|
end
|
|
|
|
### Verify that a specific IP address can be resolved
|
|
|
|
describe host('example.com', port: 80, proto: 'tcp') do
|
|
it { should be_resolvable }
|
|
its('ipaddress') { should include '192.168.1.1' }
|
|
end
