Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Multi-tenancy in Kubernetes
Here is a library or rules for the Open Policy Agent.
- open-policy-agent/gatekeeper-library: The OPA Gatekeeper policy library.

Security scanning of k8s manifest files vs running cluster
https://github.com/open-policy-agent/gatekeeper-library is the library of OPA Gatekeeper policies.

Expose Open Policy Agent/Gatekeeper Constraint Violations for Kubernetes Applications with Prometheus and Grafana
by default and exposes metrics on path ```/metrics``` . It can run locally on your development box as long as you have a valid Kubernetes configuration in your home folder (i.e. if you can run kubectl and have the right permissions). When running on the cluster a ```incluster``` parameter is passed in so that it knows where to look up for the cluster credentials. Exporter program connects to Kubernetes API every 10 seconds to scrape data from Kubernetes API. We've used [this](https://medium.com/teamzerolabs/15-steps-to-write-an-application-prometheus-exporter-in-go-9746b4520e26) blog post as the base for the code. ## Demo Let's go ahead and prepare our components so that we have a Grafana dashboard to show us which constraints have been violated and how the number of violations evolve over time. ### 0) Required tools - [Git](https://git-scm.com/downloads): A git cli is required to checkout the repo and - [Kubectl](https://kubernetes.io/docs/tasks/tools/) and a working K8S cluster - [Ytt](https://carvel.dev/ytt/): This is a very powerful yaml templating tool, in our setup it's used for dynamically overlaying a key/value pair in all constraints. It's similar to Kustomize, it's more flexibel than Kustomize and heavily used in some [Tanzu](https://tanzu.vmware.com/tanzu) products. - [Kustomize](https://kustomize.io/): Gatekeeper-library relies on Kustomize, so we need it too. - [Helm](https://helm.sh/): We will install Prometheus and Grafana using helm - Optional: [Docker](https://www.docker.com/products/docker-desktop): Docker is only optional as we already publish the required image on dockerhub. ### 1) Git submodule update Run ```git submodule update --init``` to download gatekeeper-library dependency. This command will download the [gatekeeper-library](https://github.com/open-policy-agent/gatekeeper-library) dependency into folder ```gatekeeper-library/library``` . ### 2) Install OPA/Gatekeeper If your K8S cluster does not come with Gatekeeper preinstalled, you can use install it as explained [here](https://open-policy-agent.github.io/gatekeeper/website/docs/install/). If you are familiar with helm, the easiest way to install is as follows: ```bash helm repo add gatekeeper https://open-policy-agent.github.io/gatekeeper/charts helm install gatekeeper/gatekeeper --generate-name

Who is doing image scanning on an admission controller? (Open source)
Gatekeeper library has example policies for restricting image repositories: https://github.com/open-policy-agent/gatekeeper-library/tree/master/library/general

Mental models for understanding Kubernetes Pod Security Policy PSP
You should check out the Gatekeeper project. There's plenty of templates available for use without having to write a single line of rego for most use cases (e.g https://github.com/open-policy-agent/gatekeeper-library)

Understanding Container Security
Scanning your container images for vulnerabilities is a good approach. But this scanning is not one time job, it should be done regularly (weekly, monthly, etc.) You need to follow vulnerability reports and fix all of the vulnerabilities as soon as possible. I recommend some open-source tools that could be useful: Trivy, Docker-Bench, Grype.

Security docker app
For Docker configuration I have used this in the past (it utilizes the CIS Docker Benchmark): https://github.com/docker/docker-bench-security
- What's your favourite Docker Image, and why?
-
Docker image scan against cis benchmark
So the main tool to scan against the CIS Docker benchmark (I'm presuming that's the one you're interested in) is https://github.com/docker/docker-bench-security .

Importing certificates into containers
when deploying images on cloud, I always run it thru "docker bench security" It helps finding potential security holes in my images.

Other tools you can use are linux-bench, docker-bench, kube-bench, kube-hunter, kube-striker, Cloud Custodian, OVAL, and OS Query.

What do you have within your pipelines to ensure that containers deployed are secure?
I run https://github.com/docker/docker-bench-security against my environment. I would determine what was non-applicable/not scored and then start with scored. Then I would do not scored. My team had made their own Dockerfiles when I started and just grabbed whatever image/version and getting things baselined was not fun. I had to do this for docker-compose and stay on version 2 yml as otherwise I had to go to swarm.
What are some alternatives?
