Machineset

machineset is an example client-side implementation of a MachineSet, which may be included in the Cluster API in the future. It allows you to declaratively scale a group of Machines identified by a label selector.

Building

$ cd $GOPATH/src/k8s.io/
$ git clone git@github.com:kubernetes/kube-deploy.git
$ cd kube-deploy/cluster-api/examples/machineset
$ go build

Running

1. Create a cluster using the cluster-api tool.
   • By default, the master and node Machines from machines.yaml have the labels set=master and set=node, respectively.
2. To print out the Machines in a set, run ./machineset get set=node.
3. To scale the number of Machines up, run ./machineset scale set=node -r 3.
4. To scale them back down, run ./machineset scale set=node -r 1.
5. To see the full usage information, run ./machineset help.
