# k8-env

A Kubernetes mutating webhook server that implements environnement variable injection.

## Prerequisites

A Kubernetes cluster (v1.19+) with the `admissionregistration.k8s.io/v1beta1` API enabled.

Verify that by the following command :

```bash

kubectl api-versions | grep admissionregistration.k8s.io

```

## How to use

### 1. Create a `namespace`

Create a `namespace` with the label `env-injection: true` :

```yaml

apiVersion: v1

kind: Namespace

metadata:

  name: my-namespace

  labels:

    env-injection: true

```

### 2. Create kustomization configuration

Change the `namespace` or create a `k8-env` namespace and create a `kustomization.yaml` file :

```bash

apiVersion: kustomize.config.k8s.io/v1beta1

kind: Kustomization

namespace: k8-env

resources:

  - https://raw.githubusercontent.com/orange-cloudavenue/k8-env/v0.1.0/manifests/manifests.yaml

images:

- name: k8-env

  newName: ghcr.io/orange-cloudavenue/k8-env

  newTag: v0.1.0

configMapGenerator:

  - name: k8-env

    behavior: replace

    files:

      - envconfig.yaml

```

### 3. Create a `envconfig.yaml` file

Create a `envconfig.yaml` with the environment variables to inject :

```yaml

env:

  - name: ENV_VAR_1

    value: "value1"

  - name: ENV_VAR_2

    value: "value2"

```
