OLM Install

The following steps can be used to install the operator using the Operator Lifecycle Manager on any Kubernetes environment.

Cluster Setup

This guide uses minikube to deploy a Kubernetes cluster locally, follow the instructions for your platform to install. If you already have a Kubernetes cluster ready to go, skip to the OLM section.

Run minikube with a dedicated profile. Adjust the system resources as needed for your platform.

minikube start -p dapr

Operator Lifecycle Manager

Install the OLM components manually. If you already have OLM installed, skip to the Operator section.

Either

or

  • install using the operator-sdk command
operator-sdk olm install

Verify that OLM is installed. There should be two new namespaces, olm and operators created as a result.

kubectl get ns
NAME              STATUS   AGE
kube-system       Active   7d1h
default           Active   7d1h
kube-public       Active   7d1h
kube-node-lease   Active   7d1h
operators         Active   94s
olm               Active   94s

Verify that the OLM Pods are running in the olm namespace.

kubectl get pods -n olm
NAME                                READY   STATUS    RESTARTS   AGE
catalog-operator-569cd6998d-h5cbp   1/1     Running   0          39s
olm-operator-6fbbcd8c8b-qzv47       1/1     Running   0          39s
operatorhubio-catalog-m7qxq         1/1     Running   0          31s
packageserver-6cb8b48df4-wp89m      1/1     Running   0          30s
packageserver-6cb8b48df4-ww62h      1/1     Running   0          30s

That's it, OLM should be installed and availble to manage the Dapr Operator.

Operator Install

The dapr-kubernetes-operator provides a pre-made kustomization file to deploy the Dapr Kubernetes Operator with OLM:

kubectl apply -k https://github.com/dapr/kubernetes-operator//config/samples/olm

This command should:

  • Create a dapr-system namespace
  • Create a CatalogSource in the olm namespace 
    ➜ kubectl get catalogsources -n olm
NAME                    DISPLAY               TYPE   PUBLISHER        AGE
daprio-catalog          dapr.io catalog       grpc   dapr.io          11m
operatorhubio-catalog   Community Operators   grpc   OperatorHub.io   18m
  • Create an OperatorGroup in the dapr-system namespace 
    ➜ kubectl get operatorgroups -n dapr-system
NAME            AGE
dapr-operator   12m
  • Create a new Subscription for theDapr Kubernetes Operator in the new dapr-system namespace. 
    ➜ kubectl get subscriptions.operators.coreos.com -n dapr-system
NAME                 PACKAGE                    SOURCE           CHANNEL
dapr-control-plane   dapr-kubernetes-operator   daprio-catalog   alpha
    The subscription should result in an InstallPlan being created in the dapr-system namespace which finally result in the dapr-control-plane Pod running 
    ➜ kubectl get pods -n dapr-system
NAME                                  READY   STATUS    RESTARTS   AGE
dapr-control-plane-66866765b9-nzb6t   1/1     Running   0          13m

Usage

Once the operator is installed and running, new DaprControlPlane resources can be created.

Cleanup

You can clean up the operator resources by running the following commands.

kubectl delete -k https://github.com/dapr/kubernetes-operator//config/samples/olm
