Helm plugin which stops a release pods

Helm Stop Plugin

This is a Helm plugin which stops a release pods. It works by setting a release replica to zero (via helm upgrade).

Usage

$ helm stop [REPLICA_VALUE_NAME] [RELEASE_NAME] [CHART_PATH]

Example

Note: This example is a local modified version of stable/mysql chart. It is modified to add a value replicasValue which is used to set the replicas (also added) during deployment.

$ kubectl get all
