GitHub Release GitHub Build Actions GitHub Release Action License GitHub All Releases

This is an Octant plugin for Starboard which provides visibility into vulnerability assessment reports for Kubernetes workloads stored as custom security resources.

Installing

This guide shows how to install the Starboard Octant plugin. The plugin can be installed either from source, or from pre-built binary releases.

Prerequisites

  • Octant >= 0.13 should first be installed. On macOS this is as simple as brew install octant. For installation instructions on other operating systems and package managers, see Octant Installation.
  • Environment authenticated against your Kubernetes cluster

In the following instructions we assume that the $HOME/.config/octant/plugins directory is the default plugins location respected by Octant. Note that the default location might be changed by setting the OCTANT_PLUGIN_PATH environment variable when running Octant.

From the Binary Releases

Every release of Starboard Octant plugin provides binary releases for a variety of operating systems. These binary versions can be manually downloaded and installed.

  1. Download your desired version
  2. Unpack it (tar -zxvf starboard-octant-plugin_darwin_x86_64.tar)
  3. Find the starboard-octant-plugin binary in the unpacked directory, and move it to the default Octant's configuration directory (mv starboard-octant-plugin_darwin_x86_64/starboard-octant-plugin $HOME/.config/octant/plugins). You might need to create the directory if it doesn't exist already.

From Source (Linux, macOS)

Building from source is slightly more work, but is the best way to go if you want to test the latest (pre-release) version of the plugin.

You must have a working Go environment.

$ git clone git@github.com:aquasecurity/starboard-octant-plugin.git
$ cd starboard-octant-plugin
$ make install

The make install goal copies the plugin binary to the $HOME/.config/octant/plugins directory.

Getting Started

As an example let's run an old version of nginx that we know has vulnerabilities. Create an nginx Deployment in the dev namespace:

$ kubectl create deployment nginx --image nginx:1.16 --namespace dev

Run the scanner to find the vulnerabilities:

$ starboard find vulnerabilities deploy/nginx --namespace dev

In the example above we are using the Starboard CLI to populate the vulnerability information. However, another option might be the operator which populates the Starboard CRDs. No matter how the CRDs are created, they are visible within Octant.

You can now display the vulnerabilities reports in the Octant interface by following these steps:

  1. Run octant and select the dev namespace.

  2. Expand Workloads and select Deployments.

  3. Click the nginx link to display the Deployment's details.

  4. Select the Vulnerabilities tab to access the vulnerabilities report.

    The data displayed in the Vulnerabilities tab is equivalent of getting the vulnerabilities.aquasecurity.github.io resources for the nginx Deployment:

    $ starboard get vulnerabilities deploy/nginx --namespace dev --output yaml
    

    or

    $ kubectl get vulnerabilityreports.aquasecurity.github.io \
      --selector starboard.resource.kind=Deployment,starboard.resource.name=nginx \
      --namespace dev \
      --output yaml
    

Similar to displaying vulnerability reports for the specified Deployment, Starboard Octant plugin allows you to display vulnerability reports for every Kubernetes workload, such as Cron Jobs, Daemon Sets, Jobs, unmanaged Pods, Replica Sets, Replication Controllers, and Stateful Sets.

Use Cases

Displaying Vulnerabilities Summary

To display the summary of vulnerabilities for the specified workload:

  1. Expand Workloads and select desired workload.

  2. Click the link with the workload's name to display the details.

    The Status card component shows the summary of vulnerabilities in the container images of the selected workload.

Displaying Kubernetes Configuration Audit Reports

To display a configuration audit report for the specified workload, which is represented as an instance of the configauditreports.aquasecurity.github.io resource:

  1. Expand Workloads and select desired workload.

  2. Click the link with the workload's name to display the details.

    The report is shown under the Config Audit Report heading.

Displaying CIS Kubernetes Benchmark Reports

CIS Kubernetes Benchmarks reports are represented by ciskubebenchreports.aquasecurity.github.io resources, which are associated with Nodes. To display the latest report for the specified Node:

  1. Expand Nodes.

  2. Click the link with the Node's name to display the details.

  3. Select the CIS Kubernetes Benchmark tab to access the latest Kubernetes Benchmark report for that Node.

    The report displayed in the CIS Kubernetes Benchmark tab is equivalent of getting the ciskubebenchreports resource for a given Node:

    $ kubectl get ciskubebenchreports.aquasecurity.github.io \
      --selector starboard.resource.kind=Node,starboard.resource.name=minikube \
      --output yaml
    

Displaying kube-hunter Reports

Reports generated by kube-hunter are represented by kubehunterreports.aquasecurity.github.io resources. To display the latest kube-hunter report:

  1. Expand Starboard.

    The report displayed in the Starboard pane is equivalent of getting the kubehunterreports resource:

    $ kubectl get kubehunterreports.aquasecurity.github.io \
      --selector starboard.resource.kind=Cluster,starboard.resource.name=cluster \
      --output yaml
    

Uninstalling

Run the following command to remove the plugin:

rm -f $OCTANT_PLUGIN_PATH/starboard-octant-plugin

where $OCTANT_PLUGIN_PATH is the default plugins location respected by Octant. If not set, it defaults to the $HOME/.config/octant/plugins directory.
