+
+The Chef InSpec Docker resource pack allows you to audit Docker environments, including containers, images, services, and plugins.
+
+## Support
+
+The InSpec Docker resources were part of InSpec core through InSpec 6.
+Starting in InSpec 7, they're released separately as a Ruby gem.
+
+## Usage
+
+To add this resource pack to an InSpec profile, add the `inspec-docker-resources` gem as a dependency in your `inspec.yml` file:
+
+```yaml
+depends:
+  - name: inspec-docker-resources
+    gem: inspec-docker-resources
+```
+
+## Docker resources
+
+{{< inspec_resources_filter >}}
+
+The following Chef InSpec Docker resources are available in this resource pack.

+Use the `docker` Chef InSpec audit resource to test configuration data for the Docker daemon. It is a very comprehensive resource. See also: [docker_container](/inspec/resources/docker_container/) and [docker_image](/inspec/resources/docker_image/), too.
+
+## Syntax
+
+A `docker` resource block allows you to write tests for many containers:
+
+```ruby
+describe docker.containers do
+  its('images') { should_not include 'u12:latest' }
+end
+```
+
+or:
+
+```ruby
+describe docker.containers.where { names == 'flamboyant_allen' } do
+  it { should be_running }
+end
+```
+
+where
+
+- `.where()` may specify a specific item and value, to which the resource parameters are compared
+- `commands`, `ids`, `images`, `labels`, `local_volumes`, `mounts`, `names`, `networks`, `ports`, `sizes` and `status` are valid parameters for `containers`
+
+The `docker` resource block also declares allows you to write test for many images:
+
+```ruby
+describe docker.images do
+  its('repositories') { should_not include 'insecure_image' }
+end
+```
+
+or if you want to query specific images:
+
+```ruby
+describe docker.images.where { repository == 'ubuntu' && tag == '12.04' } do
+  it { should_not exist }
+end
+```
+
+where
+
+- `.where()` may specify a specific filter and expected value, against which parameters are compared
+
+## Examples
+
+The following examples show how to use this Chef InSpec audit resource.
+
+### Return all running containers
+
+```ruby
+docker.containers.running?.ids.each do |id|
+  describe docker.object(id) do
+    its('State.Health.Status') { should eq 'healthy' }
+  end
+end
+```
+
+### Verify a Docker Server and Client version
+
+```ruby
+describe docker.version do
+  its('Server.Version') { should cmp >= '1.12'}
+  its('Client.Version') { should cmp >= '1.12'}
+end
+```
+
+### Iterate over all containers to verify host configuration
+
+```ruby
+docker.containers.ids.each do |id|
+  # call Docker inspect for a specific container id
+  describe docker.object(id) do
+    its(%w(HostConfig Privileged)) { should cmp false }
+    its(%w(HostConfig Privileged)) { should_not cmp true }
+  end
+end
+```
+
+### Iterate over all images to verify the container was built without ADD instruction
+
+```ruby
+docker.images.ids.each do |id|
+  describe command("docker history #{id}| grep 'ADD'") do
+    its('stdout') { should eq '' }
+  end
+end
+```
+
+### Verify that health-checks are enabled for a container
+
+```ruby
+describe docker.object('71b5df59442b') do
+  its(%w(Config Healthcheck)) { should_not eq nil }
+end
+```
+
+## How to run the DevSec Docker baseline profile
+
+There are two ways to run the `docker-baseline` profile to test Docker via the `docker` resource.
+
+Clone the profile:
+
+```bash
+git clone https://github.com/dev-sec/cis-docker-benchmark.git
+```
+
+and then run:
+
+```bash
+inspec exec cis-docker-benchmark
+```
+
+Or execute the profile directly via URL:
+
+```bash
+inspec exec https://github.com/dev-sec/cis-docker-benchmark
+```
+
+## Resource Parameters
+
+- `commands`, `ids`, `images`, `labels`, `local_volumes`, `mounts`, `names`, `networks`, `ports`, `sizes` and `status` are valid parameters for `containers`
+
+## Resource Parameter Examples
+
+### containers
+
+`containers` returns information about containers as returned by [docker ps -a](https://docs.docker.com/engine/reference/commandline/ps/).
+
+```ruby
+describe docker.containers do
+  its('ids') { should include 'sha:71b5df59...442b' }
+  its('commands') { should_not include '/bin/sh' }
+  its('images') { should_not include 'u12:latest' }
+  its('ports') { should include '0.0.0.0:1234->1234/tcp' }
+  its('labels') { should include 'License=GPLv2' }
+end
+```
+
+### object('id')
+
+`object` returns low-level information about Docker objects. It is calling [docker inspect](https://docs.docker.com/engine/reference/commandline/info/) under the hood.

+```ruby
+describe docker.object(id) do
+  its('Configuration.Path') { should eq 'value' }
+end

+end
+```
+
+### plugins

+  its('ids') { should cmp ['6ea8176de74b', '771d3ee7c7ea'] }
+  its('versions') { should cmp ['2.3.0', '18.03.1-ce-aws1'] }
+  its('enabled') { should cmp [true, false] }
+end

+
+### version
+
+`info` returns the parsed result of [docker version](https://docs.docker.com/engine/reference/commandline/version/)
