# package
|
|
|
|
Use the `package` Chef InSpec audit resource to test if the named package and/or package version is installed on the system.
|
|
|
|
<br>
|
|
|
|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v1.0.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
A `package` resource block declares a package and (optionally) a package version:
|
|
|
|
describe package('name') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
where
|
|
|
|
* `('name')` must specify the name of a package, such as `'nginx'`
|
|
* `be_installed` is a valid matcher for this resource
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
### Test if NGINX version 1.9.5 is installed
|
|
|
|
describe package('nginx') do
|
|
it { should be_installed }
|
|
its('version') { should eq '1.9.5' }
|
|
end
|
|
|
|
### Test that a package is not installed
|
|
|
|
describe package('some_package') do
|
|
it { should_not be_installed }
|
|
end
|
|
|
|
### Test that telnet is not installed
|
|
|
|
describe package('telnetd') do
|
|
it { should_not be_installed }
|
|
end
|
|
|
|
describe inetd_conf do
|
|
its('telnet') { should eq nil }
|
|
end
|
|
|
|
### Test if ClamAV (an antivirus engine) is installed and running
|
|
|
|
describe package('clamav') do
|
|
it { should be_installed }
|
|
its('version') { should eq '0.98.7' }
|
|
end
|
|
|
|
describe service('clamd') do
|
|
it { should be_enabled }
|
|
it { should be_installed }
|
|
it { should be_running }
|
|
end
|
|
|
|
### Verify if a package is installed according to my rpm database
|
|
|
|
describe package('some_package', rpm_dbpath: '/var/lib/my_rpmdb') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
### Verify if Memcached is installed, enabled, and running
|
|
|
|
Memcached is an in-memory key-value store that helps improve the performance of database-driven websites and can be installed, maintained, and tested using the `memcached` cookbook (maintained by Chef). The following example is from the `memcached` cookbook and shows how to use a combination of the `package`, `service`, and `port` Chef InSpec audit resources to test if Memcached is installed, enabled, and running:
|
|
|
|
describe package('memcached') do
|
|
it { should be_installed }
|
|
end
|
|
|
|
describe service('memcached') do
|
|
it { should be_installed }
|
|
it { should be_enabled }
|
|
it { should be_running }
|
|
end
|
|
|
|
describe port(11_211) do
|
|
it { should be_listening }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Matchers
|
|
|
|
For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
|
|
|
|
### be_held
|
|
|
|
The `be_held` matcher tests if the named package is "held". On dpkg platforms, a "held" package
|
|
will not be upgraded to a later version.
|
|
|
|
it { should be_held }
|
|
|
|
### be_installed
|
|
|
|
The `be_installed` matcher tests if the named package is installed on the system:
|
|
|
|
it { should be_installed }
|
|
|
|
### version
|
|
|
|
The `version` matcher tests if the named package version is on the system:
|
|
|
|
its('version') { should eq '1.2.3' }
|
|
|
|
You can also use the `cmp OPERATOR` matcher to perform comparisons using the version attribute:
|
|
|
|
its('version') { should cmp >= '7.35.0-1ubuntu3.10' }
|
|
|
|
`cmp` understands version numbers using Gem::Version, and can use the operators `==, <, <=, >=, and >`. It will compare versions by each segment, not as a string - so '7.4' is smaller than '7.30', for example.
