RELOADER

This chart has been DEPRECATED. Please use the Chart found here instead.

A Kubernetes controller to watch changes in ConfigMap and Secrets and then restart pods for Deployment, StatefulSet and DaemonSet

Problem

We would like to watch if some change happens in ConfigMap and/or Secret; then perform a rolling upgrade on relevant Deployment, Deamonset and Statefulset

Solution

Reloader can watch changes in ConfigMap and Secret and do rolling upgrades on Pods with their associated Deployments, Deamonsets and Statefulsets.

How to use Reloader

Configmap

For a Deployment called foo have a ConfigMap called foo-configmap. Then add this annotation to main metadata of your Deployment

kind: Deployment
metadata:
  annotations:
    configmap.reloader.stakater.com/reload: "foo-configmap"
spec:
  template:
    metadata:

Use comma separated list to define multiple configmaps.

kind: Deployment
metadata:
  annotations:
    configmap.reloader.stakater.com/reload: "foo-configmap,bar-configmap,baz-configmap"
spec:
  template:
    metadata:

Secret

For a Deployment called foo have a Secret called foo-secret. Then add this annotation to main metadata of your Deployment

kind: Deployment
metadata:
  annotations:
    secret.reloader.stakater.com/reload: "foo-secret"
spec:
  template:
    metadata:

Use comma separated list to define multiple secrets.

kind: Deployment
metadata:
  annotations:
    secret.reloader.stakater.com/reload: "foo-secret,bar-secret,baz-secret"
spec:
  template:
    metadata:
