1.10.5.2. Adding a project to the mesh using label selectors with the CLI

You can use label selectors to add a project to the Service Mesh with the CLI.

Prerequisites

Procedure

Log in to the OpenShift Container Platform CLI.
Edit the ServiceMeshMemberRoll resource.
```
$ oc edit smmr default -n istio-system
```
You can deploy the Service Mesh control plane to any project provided that it is separate from the project that contains your services.
Modify the YAML file to include namespace label selectors in the spec.memberSelectors field of the ServiceMeshMemberRoll resource.
참고
Instead of using the matchLabels field, you can also use the matchExpressions field in the selector.
```
apiVersion: maistra.io/v1
kind: ServiceMeshMemberRoll
metadata:
  name: default
  namespace: istio-system
spec:
  memberSelectors: 
```

```
  - matchLabels: 
```
2
```
      mykey: myvalue 
```

```
  - matchLabels: 
```

```
      myotherkey: myothervalue 
```

Contains the label selectors used to identify which project namespaces are included in the service mesh. If a project namespace has either label specified by the selectors, then the project namespace is included in the service mesh. The project namespace does not need both labels to be included.
