# Crossplane Stack - Metacontroller Example

## Building

### Prerequisite

For now, make sure metacontroller is installed first.

https://metacontroller.app/guide/install/#install-metacontroller

```sh

# Create metacontroller namespace.

kubectl create namespace metacontroller

# Create metacontroller service account and role/binding.

kubectl apply -f https://raw.githubusercontent.com/GoogleCloudPlatform/metacontroller/master/manifests/metacontroller-rbac.yaml

# Create CRDs for Metacontroller APIs, and the Metacontroller StatefulSet.

kubectl apply -f https://raw.githubusercontent.com/GoogleCloudPlatform/metacontroller/master/manifests/metacontroller.yaml

```

### Create the HelloWorld Metacontroller Extension

Create the extension.  The files in this repository will be bundled into a docker image.  The sync.py script, controller.yaml, and webhook.yaml are taken directly from  with only cosmetic changes.

```sh

DOCKER_ORG=displague

sed -i s/displague/$DOCKER_ORG/ .registry/install.yaml # TODO(displague) this needs to change

docker build . --tag $DOCKER_ORG/sample-extension-metacontroller

docker push $DOCKER_ORG/sample-extension-metacontroller

```

The dockerfile is composed of the Crossplane metadata necessary to be considered an extension, but it also includes a script (`install.sh`, the `CMD` of this docker image) to handle installation, updating, and removal of the Extension life-cycle controller.  Arguments may be supplied to this command (in the future) to denote which version of the controller to deploy.  While not implemented currently, these arguments would be provided in `install.yaml`.

### Install the HelloWorld Extension

Then creates a CR for a the extension to be installed.

```sh

cat > install-the-extension.yaml < deploy-a-resource-the-extension-handles.yaml <!

```
