For future reference, kubectl replace is now a very handy way to achieve this

kubectl replace -f some_spec.yaml Let you update a complete configMap (or other objects)

Copy/pasted from the help:

# Replace a pod using the data in pod.json.
kubectl replace -f ./pod.json

# Replace a pod based on the JSON passed into stdin.
cat pod.json | kubectl replace -f -

# Update a single-container pod's image version (tag) to v4
kubectl get pod mypod -o yaml | sed 's/\(image: myimage\):.*$/\1:v4/' | kubectl replace -f -

# Force replace, delete and then re-create the resource
kubectl replace --force -f ./pod.json
