• BMO logs

kubectl logs -n metal3 pod/cluster-api-provider-baremetal-controller-manager-0 -c manager -f

• List ironic nodes

export OS_TOKEN=fake-token
export OS_URL=http://localhost:6385/
openstack baremetal node list

• Create a new node on KVM for Minikube

go run $GOPATH/src/github.com/metal3-io/baremetal-operator/cmd/make-bm-worker/main.go -address ipmi://192.168.111.1:6232 -password password -user admin -boot-mac 00:6c:f2:66:00:fc worker-1 | kubectl create -n metal3 -f -

• Patch SC to be the default one

kubectl patch storageclass mycluster-ceph-rbd -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

• Clean pods in state X

kubectl get po --all-namespaces --field-selector 'status.phase!=Running' -o json | kubectl delete -f -

• Get JSONPATH label

oc --config ocp/auth/kubeconfig get machines -n openshift-machine-api --no-headers -o jsonpath="{['items'][0]['metadata']['labels']['machine\.openshift\.io/cluster-api-cluster']}"
