Flannel is a virtual network that gives a subnet to each host for use with
container runtimes.

This charm will deploy flannel as a background service, and configure CNI for
use with flannel, on any principal charm that implements the
[`kubernetes-cni`](https://github.com/juju-solutions/interface-kubernetes-cni) interface.

## Usage

The flannel charm is a
[subordinate](https://juju.is/docs/sdk#heading--subordinate-charms).
This charm will require a principal charm that implements the `kubernetes-cni`
interface in order to properly deploy.

```
juju deploy flannel
juju deploy etcd
juju deploy kubernetes-control-plane
juju deploy kubernetes-worker
juju add-relation flannel etcd
juju add-relation flannel kubernetes-control-plane
juju add-relation flannel kubernetes-worker
```

## Known Limitations

This subordinate does not support being co-located with other deployments of
the flannel subordinate (to gain 2 vlans on a single application). If you
require this support please file a bug.

This subordinate also leverages juju-resources, so it is currently only available
on juju 2.0+ controllers.
