| Controller |
| ---------- |
| |
| # Deploying |
| |
| When deploying the Controller, it needs to be deployed via a |
| [StatefulSet][StatefulSet]. This is because each Controller |
| instance needs to know which index it is. The Controller |
| can be deployed with: |
| |
| ``` |
| kubectl apply -f controller.yml |
| ``` |
| |
| # Controller Deployment Changes |
| ## Increase Controller Count |
| |
| You will need to update the number of replicas for the |
| Controllers [here](https://github.com/apache/incubator-openwhisk-deploy-kube/tree/master/kubernetes/controller/controller.yml#L10) |
| and the value of CONTROLLER_INSTANCES [here](https://github.com/apache/incubator-openwhisk-deploy-kube/tree/master/kubernetes/controller/controller.yml#L60) |
| and the value of AKKA_CLUSTER_SEED_NODES [here](https://github.com/apache/incubator-openwhisk-deploy-kube/tree/master/kubernetes/controller/controller.yml#L88) |
| and redeploy. |
