+## Building an odo project fails because of an existing image stream
+If you try to create an image stream that already exists in your cluster and then build an odo project, you might receive error messages in the build log:
+```
+Failed to create component with name <component name>. Please use odo config view to view settings used to create component. Error: imagestreams.image.openshift.io "<image stream name>" already exists unable to create ImageStream for <image stream name>
+```
+
+**Workaround:**
+1. Run `kubectl get is` to get the existing image stream.
+2. Run `kubectl delete is <existing image stream name>` to manually delete the existing image stream.
