How do I use a feature flag?

Question

I am trying to use the VSphere provider but I am being told "It's behind a feature flag", how do I use a feature flag with Juju?

Answer 1

You need to set the JUJU_DEV_FEATURE_FLAGS variable to whatever feature you are trying to enable. You do this when you bootstrap.

JUJU_DEV_FEATURE_FLAGS=vsphere-provider juju bootstrap controllername cloudname
