[![Coverage Status](https://coveralls.io/repos/github/inspec/inspec/badge.svg?branch=main)](https://coveralls.io/github/inspec/inspec?branch=main)



Chef InSpec is an open-source testing framework for infrastructure with a human- and machine-readable language for specifying compliance, security and policy requirements.



```ruby

# Disallow insecure protocols by testing



describe package('telnetd') do

  it { should_not be_installed }

end



describe inetd_conf do

  its("telnet") { should eq nil }

end

```



Chef InSpec makes it easy to run your tests wherever you need. More options are found in our [CLI docs](https://docs.chef.io/inspec/cli/).



```bash

# run test locally

inspec exec test.rb



# run test on remote host via SSH

inspec exec test.rb -t ssh://user@hostname -i /path/to/key



# run test on remote host using SSH agent private key authentication. Requires Chef InSpec 1.7.1

inspec exec test.rb -t ssh://user@hostname



# run test on remote windows host via WinRM

inspec exec test.rb -t winrm://Administrator@windowshost --password 'your-password'



# run test on remote windows host via WinRM as a domain user

inspec exec test.rb -t winrm://windowshost --user 'UserName@domain' --password 'your-password'



# run test on docker container

inspec exec test.rb -t docker://container_id

```



# Features



- Built-in Compliance: Compliance no longer occurs at the end of the release cycle

- Targeted Tests: Chef InSpec writes tests that specifically target compliance issues

- Metadata: Includes the metadata required by security and compliance pros

- Easy Testing: Includes a command-line interface to run tests quickly



## Installation



Chef InSpec requires Ruby ( >= 3.0.3 ).



All currently supported versions of Chef InSpec (4.0 and later) require accepting the EULA to use. Please visit the [license acceptance page](https://docs.chef.io/licensing/accept/) on the Chef docs site for more information.



### Install as package



The Chef InSpec package is available for MacOS, RedHat, Ubuntu and Windows. Download the latest package at [Chef InSpec Downloads](https://www.chef.io/downloads/tools/inspec) or install Chef InSpec via script:



```text

# RedHat, Ubuntu, and macOS

curl https://chefdownload-commercial.chef.io/install.sh?license_id= | sudo bash -s -- -P inspec



# Windows

. { iwr -useb https://chefdownload-commercial.chef.io/install.ps1?license_id= } | iex; install -project inspec

```



Replace `` with your license ID.



For more information about the install scripts, see the [Chef Install Script documentation](/chef_install_script/).



### Install it via rubygems.org



Installing Chef InSpec from source may require installing ruby build tools to manage gem dependencies. (A compiler-free variant is available with reduced functionality; use `inspec-core-bin` and `inspec-core`.)



To install build tools, use your package manager.



For CentOS/RedHat/Fedora:



```bash

yum -y install ruby ruby-devel make gcc gcc-c++

```



For Ubuntu:



```bash

apt-get -y install ruby ruby-dev gcc g++ make

```



To install the `inspec` executable, which requires accepting the [Chef License](https://docs.chef.io/chef_license_accept.html), run:



```bash

gem install inspec-bin

```



You may also use `inspec` as a library, with no executable. This does not require accepting the license. To install the library as a gem, run:



```bash

gem install inspec

```



### Usage via Docker



Download the image and define a function for convenience:



For Linux:



```

docker pull chef/inspec

function inspec { docker run -it --rm -v $(pwd):/share chef/inspec "$@"; }

```



For Windows (PowerShell):



```

docker pull chef/inspec

function inspec { docker run -it --rm -v "$(pwd):/share" chef/inspec $args; }

```



If you call `inspec` from your shell, it automatically mounts the current directory into the Docker container. Therefore you can easily use local tests and key files. Note: Only files in the current directory and sub-directories are available within the container.



```

$ ls -1

vagrant

test.rb



$ inspec exec test.rb -t ssh://[email protected]:11022 -i vagrant

..



Finished in 0.04321 seconds (files took 0.54917 seconds to load)

2 examples, 0 failures

```



To scan the docker containers running on the host using the containerized InSpec, we need to bind-mount the Unix socket `/var/run/docker.sock` from the host machine to the InSpec Container.



```

docker pull chef/inspec

function inspec { docker run -it --rm -v $(pwd):/share -v /var/run/docker.sock:/var/run/docker.sock chef/inspec "$@"; }

```

`/var/run/docker.sock` is the Unix socket the Docker daemon listens on by default.



### Install it from source



Note that installing from OS packages from [the download page](https://www.chef.io/downloads/tools/inspec) is the preferred method.



That requires [bundler](http://bundler.io/):



```bash

bundle install

bundle exec inspec help

```



To install it as a gem locally, run:



```bash

gem build inspec.gemspec

gem install inspec-*.gem

```



On Windows, you need to install [Ruby](http://rubyinstaller.org/downloads/) with [Ruby Development Kit](https://github.com/oneclick/rubyinstaller/wiki/Development-Kit) to build dependencies with its native extensions.



### Install via Chef Habitat



Currently, this method of installation only supports Linux. See the [Chef Habitat site](https://www.habitat.sh/) for more information.



Download the `hab` binary from the [Chef Habitat](https://www.habitat.sh/docs/get-habitat/) site.



```bash

hab pkg install chef/inspec --binlink



inspec

```



### Run Chef InSpec



You should now be able to run:



```bash

$ inspec --help

Commands:

  inspec archive PATH                                       # archive a profile to tar.gz (default) ...

  inspec check PATH                                         # verify all tests at the specified PATH

  inspec automate SUBCOMMAND ...                            # Chef Automate commands

  inspec compliance SUBCOMMAND ...                          # Chef Automate commands (backwards compatible alias)

  inspec detect                                             # detect the target OS

  inspec exec PATH(S)                                       # run all test files at the specified PATH.

  inspec help [COMMAND]                                     # Describe available commands or one spe...

  inspec init TEMPLATE ...                                  # Scaffolds a new project

  inspec json PATH                                          # read all tests in PATH and generate a ...

  inspec shell                                              # open an interactive debugging shell

  inspec supermarket SUBCOMMAND ...                         # Supermarket commands

  inspec version                                            # prints the version of this tool



Options:

  [--diagnose], [--no-diagnose]  # Show diagnostics (versions, configurations)

```



# Examples



* Only accept requests on secure ports - This test ensures that a web server is only listening on well-secured ports.



```ruby

describe port(80) do

  it { should_not be_listening }

end



describe port(443) do

  it { should be_listening }

  its('protocols') {should include 'tcp'}

end

```



* Test your `kitchen.yml` file to verify that only Vagrant is configured as the driver.  The %w() formatting will

pass rubocop linting and allow you to access nested mappings.



```ruby

describe yaml('.kitchen.yml') do

  its(%w(driver name)) { should eq('vagrant') }

end

```



Also have a look at our examples for:

- [Using Chef InSpec with Test Kitchen & Chef Infra](https://github.com/chef/inspec/tree/main/examples/kitchen-chef)

- [Using Chef InSpec with Test Kitchen & Puppet](https://github.com/chef/inspec/tree/main/examples/kitchen-puppet)

- [Using Chef InSpec with Test Kitchen & Ansible](https://github.com/chef/inspec/tree/main/examples/kitchen-ansible)

- [Implementing an Chef InSpec profile](https://github.com/chef/inspec/tree/main/examples/profile)



## Or tests: Testing for a OR b



* Using describe.one, you can test for a or b.  The control will be marked as passing if EITHER condition is met.



```ruby

control 'or-test' do

  impact 1.0

  title 'This is a OR test'

  describe.one do

    describe ssh_config do

      its('Protocol') { should eq('3') }

    end

    describe ssh_config do

      its('Protocol') { should eq('2') }

    end

  end

end

```



## Command Line Usage



### exec



Run tests against different targets:



```bash

# run test locally

inspec exec test.rb



# run test on remote host on SSH

inspec exec test.rb -t ssh://user@hostname



# run test on remote windows host on WinRM

inspec exec test.rb -t winrm://Administrator@windowshost --password 'your-password'



# run test on docker container

inspec exec test.rb -t docker://container_id



# run test on podman container

inspec exec test.rb -t podman://container_id --podman-url "unix:///run/user/1000/podman/podman.sock"



# run with sudo

inspec exec test.rb --sudo [--sudo-password ...] [--sudo-options ...] [--sudo_command ...]



# run in a subshell

inspec exec test.rb --shell [--shell-options ...] [--shell-command ...]



# run a profile targeting AWS using env vars

inspec exec test.rb -t aws://



# or store your AWS credentials in your ~/.aws/credentials profiles file

inspec exec test.rb -t aws://us-east-2/my-profile



# run a profile targeting Azure using env vars

inspec exec test.rb -t azure://



# or store your Azure credentials in your ~/.azure/credentials profiles file

inspec exec test.rb -t azure://subscription_id

```



### detect



Verify your configuration and detect



```bash

id=$( docker run -dti ubuntu:14.04 /bin/bash )

inspec detect -t docker://$id

```



Which will provide you with:



```

{"family":"ubuntu","release":"14.04","arch":null}

```

[![Slack](https://community-slack.chef.io/badge.svg)](https://community-slack.chef.io/)



## Testing Chef InSpec



We offer `unit` and `integration` tests.



- `unit` tests ensure the intended behaviour of the implementation

- `integration` tests run against Docker-based VMs via test-kitchen and [kitchen-inspec](https://github.com/chef/kitchen-inspec)



### Unit tests



```bash

bundle exec rake test

```



If you like to run only one test file:



```bash

bundle exec m test/unit/resources/user_test.rb

```



You may also run a single test within a file by line number:



```bash

bundle exec m test/unit/resources/user_test.rb -l 123

```



### Integration tests



These tests download various virtual machines, to ensure Chef InSpec is working as expected across different operating systems.



These tests require the following gems:



- test-kitchen

- kitchen-dokken

- kitchen-inspec



These gems are provided via the `integration` group in the project's Gemfile.



In addition, these test require Docker to be available on your machine or a remote Docker machine configured via the standard Docker environment variables.



#### Running Integration tests



List the various test instances available:



```bash

KITCHEN_YAML=kitchen.dokken.yml bundle exec kitchen list

```



The platforms and test suites are configured in the `kitchen.dokken.yml` file. Once you know which instance you wish to test, test that instance:



```bash

KITCHEN_YAML=kitchen.dokken.yml bundle exec kitchen test 

```



You may test all instances in parallel with:



```bash

KITCHEN_YAML=kitchen.dokken.yml bundle exec kitchen test -c 3

```
