demo: Error from server: Invalid JSON Patch

After running:

$ kubectl patch offlinevirtualmachine testvm --type merge -p '{"spec":{"running":true}}'

I get the $SUBJECT error.

C:\minikube> kubectl get --all-namespaces pods
NAMESPACE     NAME                                    READY     STATUS    RESTARTS   AGE

Shouldn’t also the virt-controller-5c74754ddd-tbhkf running? I am following this guide

I’m sharing this having gone through the same battle yesterday with the kubectl run command. If you’re running this on Windows using Powershell you’ll need to create a variable and assign the JSON (using the ConvertTo-Json routine) first. Then use that variable in your kubectl commands.

From the OP’s code:

$ kubectl patch offlinevirtualmachine testvm --type merge -p '{"spec":{"running":true}}'

Becomes:

$myjson = '{"spec":{"running":true}}' | ConvertTo-Json
$ kubectl patch offlinevirtualmachine testvm --type merge -p $myjson

Hope that helps! 😃
