RELOADER
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 your Deployment
metadata:
annotations:
configmap.reloader.stakater.com/reload: "foo-configmap"
Use comma separated list to define multiple configmaps.
metadata:
annotations:
configmap.reloader.stakater.com/reload: "foo-configmap, bar-configmap, baz-configmap"
Secret
For a Deployment called foo have a Secret called foo-secret. Then add this annotation to your Deployment
metadata:
annotations:
secret.reloader.stakater.com/reload: "foo-secret"
Use comma separated list to define multiple secrets.
metadata:
annotations:
secret.reloader.stakater.com/reload: "foo-secret, bar-secret, baz-secret"
