# Rekonfig

Rekonfig monitors `Deployment` and `ConfigMap`/`Secret` mounted, ensures that each `Deployment`'s `Pod` always have up to date configuration.

Whenever a `ConfigMap` or `Secret` is updated, Rekonfig trigger a `Rolling Update` of the `Deployment`.

## Installation

To deploy Rekonfig to a Kubernetes cluster.

```bash

$ kubectl apply -f ./deploy

```

## Configuration

Rekonfig watches all `Deployment` within a Kubernetes cluster but only processes those with the annotation `rekonfig.gitops.in/update-on-konfig-change: "true"`.

As shown below, once enabled, Rekonfig will set the configuration hash as an annotation `rekonfig.gitops.in/konfig-hash` on the `Deployment`'s `PodTemplate`.

```yaml

apiVersion: apps/v1beta1

kind: StatefulSet

metadata:

  annotations:

    rekonfig.gitops.in/update-on-konfig-change: "true"

  labels:

    app: my-app

  name: my-app

  namespace: default

spec:

  replicas: 1

  selector:

    matchLabels:

      app: my-app

  serviceName: my-app-headless

  template:

    metadata:

      annotations:

        rekonfig.gitops.in/konfig-hash: ""

# ...

```

## Test
