machine-controller

Machine-Controller uses docker-machine and k8s CRD to provision machine on the cloud

Building

make

Usage

Creating Machine

Install Docker-Machine first

https://docs.docker.com/machine/install-machine/

Create machine custom resource definition

kubectl create -f example/machine-crd.yml

Run the machine controller

./bin/machine-controller --config ~/.kube/config

Create a digitalocean machine

kubectl create -f example/digitalocean-example.yml

kubectl create -f example/amazonec2-example.yml

Uploading Schemas

Each machine driver has its own driver options. We get these driver options and upload them to a schema CRD. Then later we can generate go type files base on these schemas.

Creating the schema CRD

kubectl create -f example/schema-crd.yml

Creating the Machine Driver CRD

kubectl create -f example/machine-driver-crd.yml

Creating machine drivers

kubectl create -f example/amazonec2-machine-driver.yml

kubectl create -f example/digitalocean-machine-driver.yml

$ kubectl get machinedrivers                                                                                                                                                                                                                                                                                                                             1  BR master 
NAME           KIND
amazonec2      MachineDriver.v3.management.cattle.io
digitalocean   MachineDriver.v3.management.cattle.io

Once the machine driver is created, a schema will be created automatically.

$ kubectl get dynamicschema                                                                                                                                                                                                                                                                                                                                 BR master 
NAME                 KIND
amazonec2config      DynamicSchema.v3.management.cattle.io
digitaloceanconfig   DynamicSchema.v3.management.cattle.io

Generate the go files base on schemas

go generate

package generator
