I don't think we'll support removing multus for the time being, if ever. I'm going to make it so that the operator blocks changing this field. Tested on the build 4.0.0-0.nightly-2019-03-28-210640
The field cannot be changed as the c#1 mentioned.
conditions:
- lastTransitionTime: "2019-03-29T05:38:31Z"
message: 'Not applying unsafe configuration change: invalid configuration: [cannot
change DisableMultiNetwork]. Use ''oc edit network.operator.openshift.io cluster''
to undo the change.'
reason: InvalidOperatorConfig
status: "True"
type: Failing

Description of problem: After setup cluster with multus disabled, we can enable it by editing the networkconfig, but when the multus is running we cannot remove it by changing the disableMultiNetwork to true. Version-Release number of selected component (if applicable): 4.0.0-0.nightly-2019-03-06-074438 How reproducible: always Steps to Reproduce: 1. Setup cluster with the multus disabled # cat cluster-netwrok-03-config.yml --- apiVersion: networkoperator.openshift.io/v1 kind: NetworkConfig metadata: name: cluster spec: clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 defaultNetwork: openshiftSDNConfig: mode: NetworkPolicy type: OpenshiftSDN serviceNetwork: - 172.30.0.0/16 disableMultiNetwork: true status: {} 2. Update the networkconfig to enable the multus # oc edit networkconfig cluster 3. Check that the multus pods are running well 4. Update the networkconfig again to disable the multus # oc edit networkconfig cluster 5. Check the multus pods again Actual results: The multus will still be running there while the network operator shows that it is disabled. # oc get cm -n openshift-network-operator applied-cluster -o yaml apiVersion: v1 data: applied: '{"clusterNetwork":[{"cidr":"10.128.0.0/14","hostPrefix":23}],"serviceNetwork":["172.30.0.0/16"],"defaultNetwork":{"type":"OpenShiftSDN","openshiftSDNConfig":{"mode":"NetworkPolicy","vxlanPort":4789,"mtu":8951}},"disableMultiNetwork":true,"deployKubeProxy":false,"kubeProxyConfig":{"bindAddress":"0.0.0.0","proxyArguments":{"metrics-bind-address":["0.0.0.0:9101"]}}}' kind: ConfigMap ... Expected results: Should be able to disable multus on a running cluster. Additional info: Multus service info after change it to disable. # oc get po,ds -n openshift-multus NAME READY STATUS RESTARTS AGE pod/multus-8g52t 1/1 Running 2 160m pod/multus-8sc9p 1/1 Running 0 140m pod/multus-dzwgp 1/1 Running 0 140m pod/multus-kf8h9 1/1 Running 0 140m pod/multus-phs9x 1/1 Running 2 160m pod/multus-xww8p 1/1 Running 2 160m NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE daemonset.extensions/multus 6 6 6 6 6 beta.kubernetes.io/os=linux 160m
