Helm Install, "Error: create: failed to create: namespaces "sumologic" not found"

[JeremyProffitt]

The Helm examples, should be updated for Helm v3

Helm 3 also does not respect the -namespace flag, you must create the namespace manually:

kubectl create namespace sumologic

and set it as the default name space before running helm

kubectl config set-context --namespace=sumologic

this is discussed here: helm/helm#5628
