+$ kubectl patch deployment parse-parse-dashboard --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
+$ kubectl patch deployment parse-parse-server --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
+$ kubectl patch deployment parse-mongodb --type=json -p='[{"op": "remove", "path": "/spec/selector/matchLabels/chart"}]'
