# os
|
|
|
|
Use the `os` Chef InSpec audit resource to test the platform on which the system is running.
|
|
|
|
<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
|
|
|
|
An `os` resource block declares the platform to be tested. The platform may specified via matcher or control block name. For example, using a matcher:
|
|
|
|
describe os.family do
|
|
it { should eq 'platform_family_name' }
|
|
end
|
|
|
|
* `'platform_family_name'` (a string) is one of `aix`, `bsd`, `darwin`, `debian`, `hpux`, `linux`, `redhat`, `solaris`, `suse`, `unix`, or `windows`
|
|
|
|
The parameters available to `os` are:
|
|
|
|
* `:name` - the operating system name, such as `centos`
|
|
* `:family` - the operating system family, such as `redhat`
|
|
* `:release` - the version of the operating system, such as `7.3.1611`
|
|
* `:arch` - the architecture of the operating system, such as `x86_64`
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
### Test for RedHat
|
|
|
|
describe os.family do
|
|
it { should eq 'redhat' }
|
|
end
|
|
|
|
### Test for Ubuntu
|
|
|
|
describe os.family do
|
|
it { should eq 'debian' }
|
|
end
|
|
|
|
### Test for Microsoft Windows
|
|
|
|
describe os.family do
|
|
it { should eq 'windows' }
|
|
end
|
|
|
|

### os.family? Helpers
|
|
|
|
The `os` audit resource includes a collection of helpers that enable more granular testing of platforms, platform names, architectures, and releases. Use any of the following platform-specific helpers to test for specific platforms:
|
|
|
|
* `aix?`
|
|
* `bsd?` (including Darwin, FreeBSD, NetBSD, and OpenBSD)
|
|
* `darwin?`
|
|
* `debian?`
|
|
* `hpux?`
|
|
* `linux?` (including Alpine Linux, Amazon Linux, ArchLinux, CoreOS, Exherbo, Fedora, Gentoo, and Slackware)
|
|
* `redhat?` (including CentOS)
|
|
* `solaris?` (including Nexenta Core, OmniOS, Open Indiana, Solaris Open, and SmartOS)
|
|
* `suse?`
|
|
* `unix?`
|
|
* `windows?`
|
|
|
|
For example, to test for Darwin use:
|
|
|
|
describe os.bsd? do
|
|
it { should eq true }
|
|
end
|
|
|
|
To test for Windows use:
|
|
|
|
describe os.windows? do
|
|
it { should eq true }
|
|
end
|
|
|
|
and to test for Redhat use:
|
|
|
|
describe os.redhat? do
|
|
it { should eq true }
|
|
end
|
|
|
|
Use the following helpers to test for operating system names, releases, and architectures:
|
|
|
|
describe os.name do
|
|
it { should eq 'foo' }
|
|
end
|
|
|
|
describe os.release do
|
|
it { should eq 'foo' }
|
|
end
|
|
|
|
describe os.arch do
|
|
it { should eq 'foo' }
|
|
end
|
|
|
|
### os.family names
|
|
|
|
Use `os.family` to enable more granular testing of platforms, platform names, architectures, and releases. Use any of the following platform-specific names to test for specific platforms:
|
|
|
|
* `aix`
|
|
* `bsd` For platforms that are part of the Berkeley OS family `darwin`, `freebsd`, `netbsd`, and `openbsd`.
|
|
* `debian`
|
|
* `hpux`
|
|
* `linux`. For platforms that are part of the Linux family `alpine`, `amazon`, `arch`, `coreos`, `exherbo`, `fedora`, `gentoo`, and `slackware`.
|
|
* `redhat`. For platforms that are part of the Redhat family `centos`.
|
|
* `solaris`. For platforms that are part of the Solaris family `nexentacore`, `omnios`, `openindiana`, `opensolaris`, and `smartos`.
|
|
* `suse`
|
|
* `unix`
|
|
* `windows`
|
|
|
|
For example, both of the following tests should have the same result:
|
|
|
|
```ruby
|
|
if os.family == 'debian'
|
|
describe port(69) do
|
|
its('processes') { should include 'in.tftpd' }
|
|
end
|
|
elsif os.family == 'redhat'
|
|
describe port(69) do
|
|
its('processes') { should include 'xinetd' }
|
|
end
|
|
end
|
|
|
|
if os.debian?
|
|
describe port(69) do
|
|
its('processes') { should include 'in.tftpd' }
|
|
end
|
|
elsif os.redhat?
|
|
describe port(69) do
|
|
its('processes') { should include 'xinetd' }
|
|
end
|
|
end
|
|
```
