How to update/modify an existing acs-engine based Kubernetes cluster

These steps describe how to change a running Kubernetes cluster deployed with acs-engine on Azure. These steps are only tested with changes targeting actually Azure resources. Changes made to Kubernetes configuration are not tested yet.

• Modify the apimodel.json file located in the _output/<clustername> folder
• Run acs-engine generate --api-model _output/<clustername>/apimodel.json. This wil update the azuredeploy* files needed for the new ARM deployment. These files are also located in the _output folder.
• Apply the changes by manually starting an ARM deployment. From within the _output/<clustername> run az group deployment --template-file azuredeploy.json --parameters azuredeploy.parameters.json --resource-group "<my-resource-group>"
• Grab a coffee
• Profit!
