Kubescape is a K8s open-source tool providing a multi-cloud K8s single pane of glass, including risk analysis, security compliance, RBAC visualizer, and image vulnerabilities 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.

Windows

Install on Windows

Requires powershell v5.0+

iwr -useb https://raw.githubusercontent.com/armosec/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

MacOS

Install on macOS

```
 brew tap kubescape/tap
```
```
 brew install kubescape-cli
```

Nix/NixOS

Install on NixOS or with nix (Community)

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/armosec/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

Scan with exceptions, objects with exceptions will be presented as `exclude` and not `fail`

Full documentation

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

Scan Helm charts

kubescape scan </path/to/directory> --submit

Kubescape will load the default value file

Offline/Air-gaped Environment Support

Video tutorial

It is possible to run Kubescape offline!

Download all artifacts

Download and save in local directory, if path not specified, will save all in ~/.kubescape

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

Copy the downloaded artifacts to the air-gaped/offline environment
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

Download and save in file, if file name is not specified, will save in ~/.kubescape/<framework name>.json

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

Copy the downloaded artifacts to the air-gaped/offline environment
Scan using the downloaded framework

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

Scan Periodically using Helm

Integrations

VS Code Extension

Scan the YAML files while writing them using the vs code extension

Lens Extension

View Kubescape scan results directly in Lens IDE using kubescape Lens extension

Building Kubescape

Windows

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

Build kubescape
```
make build
```
OR
```
go build -tags=static .
```

Linux / MacOS

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)

Build kubescape
```
make build
```
OR
```
go build -tags=static .
```
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.

    "go.testTags": "static",
    "go.buildTags": "static",
    "go.toolsEnvVars": {
        "CGO_ENABLED": "1"
    }
}

.vscode/launch.json

// .vscode/launch.json
{
    "version": "0.2.0",

            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceFolder}/main.go",
            "args": [
                "scan",
                "--logger",
                "debug"

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.
