Supported Notifiers

Kubed can send notifications via Email, SMS or Chat for various operations using appscode/go-notify library. To connect to these services, you need to create a Secret with the appropriate keys. Then pass the secret name to Kubed by setting notifierSecretName field in Kubed cluster config. Also, set clusterName to a meaningful name for you.
