Use the `submit` command if you wish to submit data manually
## Submit scan results manually
First, scan your cluster using the `json` format flag: `kubescape scan framework <name> --format json --output path/to/results.json`.

# How to build
## Build using python (3.7^) script
Kubescape can be built using:
``` sh
python build.py
```
Note: In order to built using the above script, one must set the environment
variables in this script:
+ RELEASE
+ ArmoBEServer
+ ArmoERServer
+ ArmoWebsite
+ ArmoAuthServer
## Build using go
Note: development (and the release process) is done with Go `1.17`
1. Clone Project
```
git clone https://github.com/armosec/kubescape.git kubescape && cd "$_"
```
2. Build
```
go build -o kubescape .
```
3. Run
```
./kubescape scan --submit --enable-host-scan
```
4. Enjoy :zany_face:
## Docker Build
### Build your own Docker image
1. Clone Project
```

```
2. Build
```
docker build -t kubescape -f build/Dockerfile .

# Under the hood
## Tests
Kubescape is running the following tests according to what is defined by [Kubernetes Hardening Guidance by NSA and CISA](https://www.nsa.gov/Press-Room/News-Highlights/Article/Article/2716980/nsa-cisa-release-kubernetes-hardening-guidance/)
* Non-root containers
* Immutable container filesystem
* Privileged containers
* hostPID, hostIPC privileges
* hostNetwork access
* allowedHostPaths field
* Protecting pod service account tokens
* Resource policies
* Control plane hardening
* Exposed dashboard
* Allow privilege escalation
* Applications credentials in configuration files
* Cluster-admin binding
* Exec into container
* Dangerous capabilities
* Insecure capabilities
* Linux hardening
* Ingress and Egress blocked
* Container hostPort
* Network policies
* Symlink Exchange Can Allow Host Filesystem Access (CVE-2021-25741)
## Technology
Kubescape based on OPA engine: https://github.com/open-policy-agent/opa and ARMO's posture controls.
The tools retrieves Kubernetes objects from the API server and runs a set of [regos snippets](https://www.openpolicyagent.org/docs/latest/policy-language/) developed by [ARMO](https://www.armosec.io/).
The tools retrieves Kubernetes objects from the API server and runs a set of [rego's snippets](https://www.openpolicyagent.org/docs/latest/policy-language/) developed by [ARMO](https://www.armosec.io/).
The results by default printed in a pretty "console friendly" manner, but they can be retrieved in JSON format for further processing.
