in-toto-kubectl

This is a kubectl plugin to run in-toto verification on the images in your kubernetes pods.

Install

run make deploy and the plugin should be installed to ~/.kube/plugins. You can change the target by changing the KUBEPATH environment variable. For example make deploy KUBEPATH=~/bin will install it to a user-controlled bin/ folder.

Usage

Make sure the plugin executable was installed to somewhere in your $PATH, or to add ~/.kube/plugins to your path. Afterwards, you can use it within kubectl:

kubectl in-toto pod/[podname]

In order to scan a pod, you'd have to have the link metadata and the layout in your current folder. After passing the pod/podname argument, you can also use -k and -l in the same way as in-toto-verify to pass key and layout parameters.

Extensions

The kubectl plugin uses parameter substitution to provide you with a {IMAGE_ID} parameter that you can substitute inside of your layouts.

In addition, a file (if it doesn't exist) called image_id will be populated on the directory when verification starts. This can be used to e.g., verify against the output of docker build. This second extension will disappear in future releases, and once resource type identifiers are provided by the in-toto framework.

Example

An example repository exists under the example directory. It contains all the tools you need to create a layout (using the python implementation), create signed metadata files (you will need docker to build the container). If you're using minikube to run the example, I also suggest you expose the Docker socket before executing the functionary step so as to create the image inside the container.
