Kubescape is a K8s open-source tool providing a Kubernetes single pane of glass, including risk analysis, security compliance, RBAC visualizer, and image vulnerability scanning. Kubescape scans K8s clusters, YAML files, and HELM charts, detecting misconfigurations according to multiple frameworks (such as the NSA-CISA, MITRE ATT&CK®), software vulnerabilities, and RBAC (role-based-access-control) violations at early stages of the CI/CD pipeline, calculates risk score instantly and shows risk trends over time.

It has become one of the fastest-growing Kubernetes tools among developers due to its easy-to-use CLI interface, flexible output formats, and automated scanning capabilities, saving Kubernetes users and admins precious time, effort, and resources. Kubescape integrates natively with other DevOps tools, including Jenkins, CircleCI, Github workflows, Prometheus, and Slack, and supports multi-cloud K8s deployments like EKS, GKE, and AKS.

Options and examples

Kubescape docs

Playground

Tutorials

Install on Windows

Windows

Requires powershell v5.0+

iwr -useb https://raw.githubusercontent.com/kubescape/kubescape/master/install.ps1 | iex

Note: if you get an error you might need to change the execution policy (i.e. enable Powershell) with

Set-ExecutionPolicy RemoteSigned -scope CurrentUser

Install on macOS

MacOS
  1.  brew tap kubescape/tap
    
  2.  brew install kubescape-cli
    

Install on NixOS or with nix (Community)

Nix/NixOS

Direct issues installing kubescape via nix through the channels mentioned here

You can use nix on Linux or macOS and on other platforms unofficially.

Try it out in an ephemeral shell: nix-shell -p kubescape

Install declarative as usual

NixOS:

  # your other config ...
  environment.systemPackages = with pkgs; [
    # your other packages ...
    kubescape
  ];

home-manager:

  # your other config ...
  home.packages = with pkgs; [
    # your other packages ...
    kubescape
  ];

Or to your profile (not preferred): nix-env --install -A nixpkgs.kubescape

Usage & Examples

Examples
Scan a running Kubernetes cluster and submit results to the Kubescape SaaS version
kubescape scan --submit --enable-host-scan  --verbose

Read here more about the enable-host-scan flag

Scan a running Kubernetes cluster with nsa framework and submit results to the Kubescape SaaS version
kubescape scan framework nsa --submit
Scan a running Kubernetes cluster with MITRE ATT&CK® framework and submit results to the Kubescape SaaS version
kubescape scan framework mitre --submit
Scan a running Kubernetes cluster with a specific control using the control name or control ID. List of controls
kubescape scan control "Privileged container"
Scan specific namespaces
kubescape scan --include-namespaces development,staging,production
Scan cluster and exclude some namespaces
kubescape scan --exclude-namespaces kube-system,kube-public
Scan local yaml/json files before deploying. Take a look at the demonstration. Submit the results in case the directory is a git repo. docs
kubescape scan *.yaml --submit
Scan Kubernetes manifest files from a git repository and submit the results
kubescape scan https://github.com/kubescape/kubescape --submit
Display all scanned resources (including the resources which passed)
kubescape scan --verbose
Output in json format

Add the --format-version v2 flag

kubescape scan --format json --format-version v2 --output results.json
Output in junit xml format
kubescape scan --format junit --output results.xml
Output in pdf format - Contributed by @alegrey91
kubescape scan --format pdf --output results.pdf
Output in prometheus metrics format - Contributed by @Joibel
kubescape scan --format prometheus
Output in html format

Kubescape will load the default value file

Offline/Air-gaped Environment Support

Video tutorial

It is possible to run Kubescape offline!

Download all artifacts
  1. Download and save in local directory, if path not specified, will save all in ~/.kubescape
kubescape download artifacts --output path/to/local/dir
  1. Copy the downloaded artifacts to the air-gaped/offline environment

  2. 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 the file name is not specified, will save in ~/.kubescape/<framework name>.json
kubescape download framework nsa --output /path/nsa.json
  1. Copy the downloaded artifacts to the air-gaped/offline environment

  2. Scan using the downloaded framework

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

Scan Periodically using Helm

Please follow the instructions here helm chart repo

Building Kubescape

Build on Windows

Windows
  1. Install MSYS2 & build libgit (needed only for the first time)

    build.bat all
    

You can install MSYS2 separately by running build.bat install and build libgit2 separately by running build.bat build

  1. Build kubescape

    make build
    

    OR

    go build -tags=static .
    

Build on Linux/MacOS

Linux / MacOS
  1. Install libgit2 dependency (needed only for the first time)

    make libgit2
    

cmake is required to build libgit2. You can install it by running sudo apt-get install cmake (Linux) or brew install cmake (macOS)

  1. Build kubescape

    make build
    

    OR

    go build -tags=static .
    
  2. Test

    make test
    

VS code configuration samples

You can use the sample files below to setup your VS code environment for building and debugging purposes.

.vscode/settings.json
// .vscode/settings.json
{
    "go.testTags": "static",
    "go.buildTags": "static",
    "go.toolsEnvVars": {
        "CGO_ENABLED": "1"
    }
}
.vscode/launch.json

            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceFolder}/main.go",
            "args": [
                "scan",
                "--logger",
                "debug"
            ],
            "buildFlags": "-tags=static"
        }
    ]
}

Under the hood

Technology

Kubescape is based on the OPA engine and ARMO's posture controls.

The tools retrieve Kubernetes objects from the API server and run a set of rego's snippets developed by ARMO.

The results by default are printed in a pretty "console friendly" manner, but they can be retrieved in JSON format for further processing.

Kubescape is an open source project, we welcome your feedback and ideas for improvement. We’re also aiming to collaborate with the Kubernetes community to help make the tests more robust and complete as Kubernetes develops.

Thanks to all the contributors ❤️
