Red Hat build of MicroShift

Disable the router

To disable the router in MicroShift when inbound services are not required, including in industrial IoT environments where pods connect only to southbound operational systems and northbound cloud-data systems, set ingress.status to Removed in the config.yaml file and restart the service.

Prerequisites

You installed MicroShift.
You created a MicroShift config.yaml file.
The OpenShift CLI (oc) is installed.

If you complete all the configurations that you need to make in the MicroShift config.yaml file at the same time, you can minimize system restarts.

Procedure

Update the value of ingress.status field to Removed in the MicroShift config.yaml file as shown in the following example:
Example config.yaml ingress stanza
```
# ...
ingress:
  ports:
    http: 80
    https: 443
  routeAdmissionPolicy:
    namespaceOwnership: InterNamespaceAllowed
  status: Removed
# ...
```
where:

ingress.status

Specifies whether the ingress ports remain open. When the value is set to Removed, the ports listed in ingress.ports are automatically closed. Any other settings in the ingress stanza are ignored, for example, any values in the routeAdmissionPolicy.namespaceOwnership field.
Restart the MicroShift service by running the following command:
```
$ sudo systemctl restart microshift
```
The MicroShift service outputs current configurations during restarts.

Verification

After the system restarts, verify that the router has been removed and that ingress is stopped by running the following command:
```
$ oc -n openshift-ingress get svc
```
Expected output
```
No resources found in openshift-ingress namespace.
```
