Step 2: Bring up any controllers (in order)

1.)  To bring up a MongoDB controller and pod, run the following command:

kubectl create -f controllers/phase-1

2.)  If you wish to use search, run this command next:

kubectl create -f controllers/phase-2-optional/elasticsearch-controller.yaml

3.)  If you want to use extractors, run this command as well, followed by commands to start the desired extractors:

kubectl create -f controllers/phase-2-optional/rabbitmq-controller.yaml

kubectl create -f controllers/phase-2-optional/extractors/EXTRACTOR1-controller.yaml

kubectl create -f controllers/phase-2-optional/extractors/EXTRACTOR2-controller.yaml

   .   .   .

kubectl create -f controllers/phase-2-optional/extractors/EXTRACTORN-controller.yaml

4.)  Run this command last to bring up Clowder itself:

kubectl create -f controllers/phase-3

Tip and Tricks

Scaling Extractors

...

Using the "Pseudo Pod Restart" technique requires a Replication Controller enforcing a particular pod configuration. Simply take the RC name as CONTROLLER_NAME (clowder-clowder) and the current number of replicas as N and use the command below:

kubectl scale --current-replicas=N --replicas=N rc clowder-clowder

NOTE: In order to avoid needlessly changing the current configuration, we recommend fixing --replicas == --current-replicas, but this need not be true if you intend to scale up the controller anyways.
