Common Conditionals
-------------------

The OpenStack-Helm charts make the following conditions available across
all charts, which can be set at install or upgrade time with Helm below.

Developer Mode
~~~~~~~~~~~~~~

::

    helm install local/chart --set development.enabled=true

The development mode flag should be available on all charts. Enabling
this reduces dependencies that the chart may have on persistent volume
claims (which are difficult to support in a laptop minikube environment)
as well as reducing replica counts or resiliency features to support a
minimal environment.

The glance chart for instance defines the following ``development:``
overrides:

::

    development:
      enabled: false
      storage_path: /var/lib/localkube/openstack-helm/glance/images

The ``enabled`` flag allows the developer to enable development mode.
The storage path allows the operator to store glance images in a
hostPath instead of leveraging a ceph backend, which again, is difficult
to spin up in a small laptop minikube environment. The host path can be
overriden by the operator if desired.

Resources
~~~~~~~~~

::

    helm install local/chart --set resources.enabled=true

Resource limits/requirements can be turned on and off. By default, they
are off. Setting this enabled to ``true`` will deploy Kubernetes
resources with resource requirements and limits.
