BUG REPORT

Version of Helm and Kubernetes:
Helm 2.7.0, k8s 1.7.8 on GKE

Which chart:
prometheus

What happened:
Unable to specify flag args with Values.server.extraArgs. Particularly, in prometheus 2.x there lots of flag values, e.g. --web.enable-lifecycle that work as flag-only, i.e. --web.enable-lifecycle=1 will not work. However, server-deployment.yaml template parses extraArgs as key/value and tries to set args in form --<key>=<value>.

What you expected to happen:

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know:

@haizaar Please use this syntax to specify the extraArgs

  extraArgs:
    storage.local.retention: 720h
    storage.local.num-fingerprint-mutexes: 4096

[haizaar]

Perhaps my description was not clear enough. You example converts to

--storage.local.retention=720h --storage.local.num-fingerprint-mutexes=4096

However, how how do I specify:

--web.enable-lifecycle

which is a flag option, i.e. does not accept any argument?
