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.
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.

Navigate to Catalog → Operator Management.
Select the openshift-operators project from the Projects drop-down.
