Getting started with Kubescape

Kubescape can run as a command line tool on a client, as an operator inside a cluster, as part of your CI/CD process, or more.

The best way to get started with Kubescape is to download it to the machine you use to manage your Kubernetes cluster.

Install Kubescape

curl -s https://raw.githubusercontent.com/kubescape/kubescape/master/install.sh | /bin/bash

(We're a security product; please read the file before you run it!)

Run your first scan

kubescape scan --verbose

You will see output like this:

Usage

Some documentation on using Kubescape is yet to move here from the ARMO Platform docs.

Examples

• Scan a running Kubernetes cluster:

  kubescape scan --verbose
  

  Note

  
  Read more about host scanning.

• Scan a running Kubernetes cluster with the NSA framework:

  kubescape scan framework nsa
  

• Scan a running Kubernetes cluster with the MITRE ATT&CK® framework:

  kubescape scan framework mitre
  

• Scan for a specific control, using the control name or control ID. See the list of controls.

  kubescape scan control "Privileged container"
  

• Use an alternative kubeconfig file:

  kubescape scan --kubeconfig cluster.conf
  

• Scan specific namespaces:

  kubescape scan --include-namespaces development,staging,production
  

• Exclude certain namespaces:

  kubescape scan --exclude-namespaces kube-system,kube-public
  

• Scan local YAML/JSON files before deploying:

  kubescape scan *.yaml
  

  Take a look at the demonstration](https://youtu.be/Ox6DaR7_4ZI).

• Scan Kubernetes manifest files from a Git repository:

  kubescape scan https://github.com/kubescape/kubescape
  

• Scan with exceptions

  kubescape scan --exceptions examples/exceptions/exclude-kube-namespaces.json
  

  Objects with exceptions will be presented as exclude and not fail.

  See more examples about exceptions.

• Scan Helm charts

  kubescape scan </path/to/directory>
  

  Note

  
  Kubescape will load the default VALUES file.

• Scan a Kustomize directory

  kubescape scan </path/to/directory>
  

  Note

  
  Kubescape will generate Kubernetes YAML objects using a kustomize file and scan them for security.

• Trigger in cluster components for scanning your cluster:

  If kubescape helm chart is install in your cluster we can trigger scanning of the in cluster components from the kubescape CLI.

• Compliance Score

  We offer two important metrics to assess compliance:

  • Control Compliance Score: This score measures the compliance of individual controls within a framework. It is calculated by evaluating the ratio of resources that passed to the total number of resources evaluated against that control.

    kubescape scan --compliance-threshold <SCORE_VALUE[float32]>
    

  • Framework Compliance Score: This score provides an overall assessment of your cluster's compliance with a specific framework. It is calculated by averaging the Control Compliance Scores of all controls within the framework.

    kubescape scan framework <FRAMEWORK_NAME> --compliance-threshold <SCORE_VALUE[float32]>

Output formats

• JSON:

  kubescape scan --format json --format-version v2 --output results.json
  

  Note

  
  Add the --format-version v2 flag for maximum compatibility.

• junit XML:

  kubescape scan --format junit --output results.xml
  

• PDF:

  kubescape scan --format pdf --output results.pdf

• Prometheus metrics:

  kubescape scan --format prometheus

• HTML

  kubescape scan --format html --output results.html
  

• Display all scanned resources (including the resources which passed):

  kubescape scan --verbose
  

Offline/air-gapped environment support

It is possible to run Kubescape offline! Check out our video tutorial.

Download all artifacts

1. Download the controls and save them in the local directory. If no path is specified, they will be saved in ~/.kubescape.

   kubescape download artifacts --output path/to/local/dir
   

2. Copy the downloaded artifacts to the offline system.

3. Scan using the downloaded artifacts:

   kubescape scan --use-artifacts-from path/to/local/dir
   

Download a single artifact

You can also download a single artifact, and scan with the --use-from flag:

1. Download and save in a file. If no file name is specified, the artifact will be saved as ~/.kubescape/<framework name>.json.

   kubescape download framework nsa --output /path/nsa.json
   

2. Copy the downloaded artifacts to the offline system.

3. Scan using the downloaded framework:

   kubescape scan framework nsa --use-from /path/nsa.json
   

Other ways to use Kubescape

Scan periodically using Helm

We publish a Helm chart for our in-cluster components. Please follow the instructions here

VS Code Extension

Scan your YAML files while writing them using our VS Code extension.

Lens Extension

View Kubescape scan results directly in the Lens IDE using the Kubescape Lens extension.

Playground

Experiment with Kubescape in the Kubescape playground: this scenario will install a K3s cluster and Kubescape. You can start with any of the kubescape scan commands in the examples.
