Authorino Operator

A Kubernetes Operator to manage Authorino instances.

Installation

The Operator can be installed by applying the manifests to the Kubernetes cluster or using Operator Lifecycle Manager (OLM)

Applying the manifests to the cluster

Install the Operator manifests

make install

Deploy the Operator

make deploy

<details> <summary><i>Tip:</i> Deploy a custom image of the Operator</summary> <br/> To deploy an image of the Operator other than the default <code>quay.io/kuadrant/authorino-operator:latest</code>, specify by setting the <code>OPERATOR_IMAGE</code> parameter. E.g.:

make deploy OPERATOR_IMAGE=authorino-operator:local

</details>

Installing via OLM

To install the Operator using the Operator Lifecycle Manager, you need to make the Operator CSVs available in the cluster by creating a CatalogSource resource.

The bundle and catalog images of the Operator are available in Quay.io:

<table> <tbody> <tr> <th>Bundle</th> <td><a href="https://quay.io/kuadrant/authorino-operator-bundle">quay.io/kuadrant/authorino-operator-bundle</a></td> </tr> <tr> <th>Catalog</th> <td><a href="https://quay.io/kuadrant/authorino-operator-catalog">quay.io/kuadrant/authorino-operator-catalog</a></td> </tr> </tbody> </table>

Create the namespace for the Operator

kubectl create namespace authorino-operator

Create the CatalogSource resource pointing to one of the images from in the Operator's catalog repo:

kubectl -n authorino-operator apply -f -<<EOF
apiVersion: operators.coreos.com/v1alpha1
kind: CatalogSource
metadata:
  name: operatorhubio-catalog
  namespace: authorino-operator
spec:
  sourceType: grpc
  image: quay.io/kuadrant/authorino-operator-catalog:latest
  displayName: Authorino Operator
EOF

Deploy authorino operator using operator-sdk

Install operator-sdk bin
```
make operator-sdk
```

Run operator-sdk bundle command

./bin/operator-sdk run bundle quay.io/kuadrant/authorino-operator-bundle:latest

Note: For s390x & ppc64le , use operator-sdk to install authorino-operator

Requesting an Authorino instance

Once the Operator is up and running, you can request instances of Authorino by creating Authorino CRs. E.g.:

kubectl -n default apply -f -<<EOF
apiVersion: operator.authorino.kuadrant.io/v1beta1
kind: Authorino
metadata:
  name: authorino
spec:
  listener:
    tls:
      enabled: false
  oidcServer:
    tls:
      enabled: false
EOF

The `Authorino` Custom Resource Definition (CRD)

API to install, manage and configure Authorino authorization services .

Each Authorino Custom Resource (CR) represents an instance of Authorino deployed to the cluster. The Authorino Operator will reconcile the state of the Kubernetes Deployment and associated resources, based on the state of the CR.
