What does the devel flag do in kubectl?

9/2/2019

I am following this youtube tutorial and the instructor runs this command.

helm install --name istio incubator/istio --namespace istio-system --devel
helm upgrade istio incubator/istio --reuse-values --set istio.install=true --devel

What does the --devel flag do? I cant seem to find its reference?

Omitting the --devel flag gives this error

Error: failed to download "incubator/istio" (hint: running `helm repo update` may help)

helm install --help | grep devel

  --devel                    use development versions, too. Equivalent to version '>0.0.0-0'. If --version is set, this is ignored.

HELM UPGRADE manual:

This command upgrades a release to a specified version of a chart and/or updates chart values.

Required arguments are release and chart. The chart argument can be one of: - a chart reference(‘stable/mariadb’); use ‘–version’ and ‘–devel’ flags for versions other than latest, - a path to a chart directory, - a packaged chart, - a fully qualified URL.
