# Single node update
Fetch expected machineconfig:
```
oc get mc/$(oc get mcp/master -o=jsonpath='{.spec.configuration.name}') -o yaml > mc.yaml
```
Run `oc debug node/ip-10-0-130-23.us-east-2.compute.internal` and keep it open.
In a parallel tab copy MC to the debug container:
```
oc -n openshift-machine-config-operator cp mc.yaml ip-10-0-130-23us-east-2computeinternal-debug:/tmp
```
Now in debug container it to host:
```
cp /tmp/mc.yaml /host/var/lib/mc.yaml
```
chroot into real root:
```
chroot /host
```
and pivot to new config
```
machine-config-daemon start --root-mount=/ --node-name=ip-10-0-130-23.us-east-2.compute.internal --once-from /var/lib/mc.yaml
```
Once the machine reboots annotate the node:
```
oc annotate nodes ip-10-0-130-23.us-east-2.compute.internal "machineconfiguration.openshift.io/desiredConfig"="rendered-master-5a4b2c3f977cb55f4d514b2541462f0f" --overwrite
```
and uncordon it:
```
oc adm uncordon ip-10-0-130-23.us-east-2.compute.internal
```
