Vessel

Vessel is a service that watches your kubernetes resources and runs several tools against them.

Vessel stores the results of tools that are run so that you can query them with a simple HTTP / json interface.

Available tasks

• linter
• trivy
• kubesec
• kubescore

Usage

Run with Docker (ephemeral storage)

Run:

docker run --rm -p 127.0.0.1:8089:8089/tcp --env K8S_URL=http://KUBERNETSURL --env K8S_TOKEN=TOKEN sourcesense/vessel:latest

Operator

The official and supported way, go to Vessel Operator.

Querying

The query interface is easy, you can pass in querystring the field you want to filter.
The Model of the issue Vessel Collector stores is simple:

name:  name of the resource
namespace: namespace of the resource
kind: kind of the resource
issue: the issue 
issue_metadata: addintional metadata of the issue
tool: task that generated the issue
created_at: date of the issue

Examples

Retrieving issue of deployment and job:

GET http://localhost:8089/query?kind=deployment&kind=job

Retrieving critical CVE:

GET http://localhost:8089/query?issue=CRITICAL_CVE

Development

Vessel is developed in python and built with poetry

git clone [email protected]:sourcesense/vessel.git
cd vessel
poetry install

Run Vessel as a server

 poetry run vessel server --k8s-url $K8S_URL --k8s-token $K8S_TOKEN

Run Vessel on a single resource

poetry run vessel single RESOURCE.yaml

Roadmap

• Exit code implementation for CI integration
• Admission control for Kubernetes resources
• Unique web interface for all the Vessel resources
• Implement a scoring system
• Add grype tool
• Add kubelinter tool
• TLS support over Vessel service ingresses.
