Deployer Operator

What is the Deployer Operator

Works with Virtualization Operators (KubeVirt, CloudForms, etc) in a managed cluster for deployments and day2 actions.

Getting Started

Prerequisites

• git v2.18+
• Go v1.13.4+
• operator-sdk v0.15.1
• Kubernetes v1.14+
• kubectl v1.14+

Check the Development Doc for how to contribute to the repo.

Quick Start

Ideally, 2 kubernetes clusters should be used. 1 for the hub, and 1 for the managed cluster. For this quick start, the same cluster is for the hub and managed cluster. In this example, the managed cluster toronto in namespace toronto is actually pointing to the hub cluster.

Clone Deployer Operator Repository

mkdir -p "$GOPATH"/src/github.com/IBM
cd "$GOPATH"/src/github.com/IBM
git clone https://github.com/IBM/deployer-operator.git
cd "$GOPATH"/src/github.com/IBM/deployer-operator

Build Deployer Operator

Build the deployer-operator and push it to a registry. Modify the example below to reference a container reposistory you have access to, and update cluster name and it's namespace.

operator-sdk build quay.io/johndoe/deployer-operator:v0.1.0
sed -i 's|REPLACE_IMAGE|quay.io/johndoe/deployer-operator:v0.1.0|g' deploy/operator.yaml
sed -i 's|CLUSTER_NAME|toronto|g' deploy/operator.yaml
sed -i 's|CLUSTER_NAMESPACE|toronto|g' deploy/operator.yaml
docker push quay.io/johndoe/hybriddeployable-operator:v0.1.0

Install Deployer Operator

Register the deployer-operator CRDs.

kubectl create -f deploy/crds/app.cp4mcm.ibm.com_deployers_crd.yaml
kubectl create -f deploy/crds/app.cp4mcm.ibm.com_deployersets_crd.yaml

Register the deployer-operator CRD dependencies.

kubectl create -f hack/test/app_v1alpha1_deployable_crd.yaml
kubectl create -f hack/test/app_v1beta1_application.yaml
kubectl create -f hack/test/cluster-registry-crd.yaml
kubectl create -f hack/test/clusterstatus-crd.yaml

Setup RBAC and deploy.

kubectl create -f deploy/service_account.yaml
kubectl create -f deploy/role.yaml
kubectl create -f deploy/role_binding.yaml
kubectl create -f deploy/operator.yaml

Alternatively, the operator can run locally using the operator-sdk, using the following steps:

• Start deployer operator
• kubeconfig points to a kubernetes cluster with admin priviliege
  • Note: if you actually have separate hub and managed clusters,
    • use environment variable HUBCLUSTERCONFIGFILE to point to the kubeconfig to hub cluster
    • environment variable KUBECONFIG to point to the kubeconfig to managed cluster

cd "$GOPATH"/src/github.ibm.com/IBMPrivateCloud/deployer-operator
export CLUSTERNAME=toronto
export CLUSTERNAMESPACE=toronto
operator-sdk run --local --namespace=""

Verify deployer-operator is up and running.

kubectl get deployment

Test Deployer Operator

Create the following CRs to setup the test. This will create a Deployer to claim capability in managed cluster. After Deployer is created, DeployerSet in cluster namespace is updated.

% kubectl apply -f ./examples/kubevirt.yaml
deployer.app.ibm.com/mykv created
% kubectl get deployerset --all-namespaces
