Installing the Operators

Maistra requires the ElasticSearch, Jaeger, and Kiali operators to be installed before Maistra operator itself can be installed. Please reference documentation on adding operators to a cluster for detailed instructions on how to install operators using OLM.

Installing the Maistra Operator

Open the OpenShift web console in a Web browser and:

  • Navigate to Catalog → OperatorHub.

  • Select the community Maistra Operator to display information about the Operator.

  • Click Install. On the Create Operator Subscription page, selecting All namespaces on the cluster (default).

  • Select either Automatic or Manual approval strategy. Click Subscribe.

This installs the Maistra operator and makes it available to all projects in the cluster.

Verifying Installation

The above instructions will create a new deployment within the istio-operator project, executing the operator responsible for managing the state of the Istio control plane through the ServiceMeshControlPlane.

To verify the operator is installed correctly, wait for the operator to reach the running state

$ oc get pods -n openshift-operators -l name=istio-operator

NAME                              READY     STATUS    RESTARTS   AGE
istio-operator-5cd6bcf645-fvb57   1/1       Running   0          1h

$ oc delete -n <operator-namespace> daemonset/istio-node
$ oc delete clusterrole/istio-admin
