helm knows what your kubernetes ConfigMap started with

 Today I asked my teammates how I might retrieve or recreate a missing ConfigMap. Our systems use helm to deploy ... deployments and one of the suggested this little gem:

helm get all -n namespace deploymentname  |tee deploymentname.yaml

Therein you will likely find the initial contents of the CM and can recreate it. (I just yanked out the rest of the yaml and then applied that file.)
