kernel_parameters resource
Use the kernel_parameters Chef InSpec audit resource to test multiple kernel parameters on Linux platforms.
These parameters are located under /proc/cmdline.
Availability
Install
This resource is distributed with Chef InSpec and is automatically available for use.Syntax
A kernel_parameters resource block uses where to filter entries from the systems kernel parameters. If where is omitted, all entries are selected.
describe kernel_parameters do
its('parameters') { should include "PARAMETER_NAME" }
its('values') { should include 1 }
end
describe kernel_parameters.where(parameter: "PARAMETER_NAME") do
its('values') { should eq [1] }
end
Properties
parameters
The kernel parameter to test.
values
The value of a kernel parameter.
Examples
The following examples show how to use this Chef InSpec audit resource.
Test the global forwarding setting using a where query on the kernel parameters
describe kernel_parameters.where(parameter: "net.ipv4.conf.all.forwarding") do
its('values') { should eq [1] }
end
Match a parameter using a regular expression
describe kernel_parameters.where(parameter: /^net./ ) do
its('parameters') { should include 'net.ipv4.conf.all.forwarding' }
end
