## Kyverno Overview

Kyverno is a policy engine for Kubernetes designed to enforce, validate, and mutate configurations of Kubernetes resources. It allows administrators to define policies as Kubernetes custom resources (CRDs) without requiring users to learn a new language or system.

### Key Uses

1. **Policy Enforcement**: Kyverno ensures resources comply with security, operational, or organizational policies, such as requiring specific labels, annotations, or resource limits.
2. **Validation**: It checks resources against predefined rules, ensuring configurations are correct before they are applied to the cluster.
3. **Mutation**: Kyverno can automatically modify resources on-the-fly, adding missing fields or values to Kubernetes objects.
4. **Generation**: It can generate resources like ConfigMaps or Secrets automatically when needed, helping to maintain consistency.

Kyverno simplifies governance and compliance in Kubernetes environments by automating policy management and ensuring best practices are followed.

## Prerequisites

Same as for idpbuilder installation
* Docker Engine
* Go
* kubectl
* kind

## Installation

### Build process

For building idpbuilder the source code needs to be downloaded and compiled:

```
git clone https://github.com/cnoe-io/idpbuilder.git
cd idpbuilder
go build
```

### Start idpbuilder

To start the idpbuilder with kyverno integration execute the following command:

```
idpbuilder create --use-path-routing -p https://github.com/cnoe-io/stacks//ref-implementation -p https://github.com/cnoe-io/stacks//kyverno-integration
```

After this step, you can see in ArgoCD that kyverno was installed
