+ # Kubernetes Worker
+
+### Building from the layer
+
+You can clone the kubernetes-worker layer with git and build locally if you
+have the charm package/snap installed.
+
+```shell
+# Instal the snap
+sudo snap install charm --channel=edge
+
+# Set the build environment
+export JUJU_REPOSITORY=$HOME
+
+# Clone the layer and build it to our JUJU_REPOSITORY
+git clone https://github.com/juju-solutions/kubernetes
+cd kubernetes/cluster/juju/layers/kubernetes-worker
+charm build -r
+```
+
+### Contributing
+
+TBD

+# Kubernetes Worker
+
+## Usage
+
+This charm deploys a container runtime, and additionally stands up the Kubernetes
+worker applications: kubelet, and kube-proxy.
+
+In order for this charm to be useful, it should be deployed with its companion
+charm [kubernetes-master](https://jujucharms.com/u/containers/kubernetes-master)
+and linked with an SDN-Plugin.
+
+This charm has also been bundled up for your convenience so you can skip the
+above steps, and deploy it with a single command:
+
+```shell
+juju deploy canonical-kubernetes
+```
+
+For more information about [Canonical Kubernetes](https://jujucharms.com/canonical-kubernetes)
+consult the bundle `README.md` file.
+
+
+## Scale out
+
+To add additional compute capacity to your Kubernetes workers, you may
+`juju add-unit` scale the cluster of applications. They will automatically
+join any related kubernetes-master, and enlist themselves as ready once the
+deployment is complete.
+
+## Operational actions
+
+The kubernetes-worker charm supports the following Operational Actions:
+
+#### Pause
+
+Pausing the workload enables administrators to both [drain](http://kubernetes.io/docs/user-guide/kubectl/kubectl_drain/) and [cordon](http://kubernetes.io/docs/user-guide/kubectl/kubectl_cordon/)
+a unit for maintenance.
+
+
+#### Resume
+
+Resuming the workload will [uncordon](http://kubernetes.io/docs/user-guide/kubectl/kubectl_uncordon/) a paused unit. Workloads will automatically migrate unless otherwise directed via their application declaration.
+
+## Private registry
+
+With the "registry" action that is part for the kubernetes-worker charm, you can very easily create a private docker registry, with authentication, and available over TLS. Please note that the registry deployed with the action is not HA, and uses storage tied to the kubernetes node where the pod is running. So if the registry pod changes is migrated from one node to another for whatever reason, you will need to re-publish the images.
+
+### Example usage
+
+Create the relevant authentication files. Let's say you want user `userA` to authenticate with the password `passwordA`. Then you'll do :
+
+    echo -n "userA:passwordA" > htpasswd-plain
+    htpasswd -c -b -B htpasswd userA passwordA
+
+(the `htpasswd` program comes with the `apache2-utils` package)
+
+Supposing your registry will be reachable at `myregistry.company.com`, and that you already have your TLS key in the `registry.key` file, and your TLS certificate (with `myregistry.company.com` as Common Name) in the `registry.crt` file, you would then run :
+
+    juju run-action kubernetes-worker/0 registry domain=myregistry.company.com htpasswd="$(base64 -w0 htpasswd)" htpasswd-plain="$(base64 -w0 htpasswd-plain)" tlscert="$(base64 -w0 registry.crt)" tlskey="$(base64 -w0 registry.key)" ingress=true
+
+If you then decide that you want do delete the registry, just run :
+
+    juju run-action kubernetes-worker/0 registry delete=true ingress=true
+
+## Known Limitations
+
+Kubernetes workers currently only support 'phaux' HA scenarios. Even when configured with an HA cluster string, they will only ever contact the first unit in the cluster map. To enable a proper HA story, kubernetes-worker units are encouraged to proxy through a [kubeapi-load-balancer](https://jujucharms.com/kubeapi-load-balancer)
+application. This enables a HA deployment without the need to
+re-render configuration and disrupt the worker services.
+
+External access to pods must be performed through a [Kubernetes
+Ingress Resource](http://kubernetes.io/docs/user-guide/ingress/).
+
+When using NodePort type networking, there is no automation in exposing the
+ports selected by kubernetes or chosen by the user. They will need to be
+opened manually and can be performed across an entire worker pool.
+
+If your NodePort service port selected is `30510` you can open this across all
+members of a worker pool named `kubernetes-worker` like so:
+
+```
+juju run --application kubernetes-worker open-port 30510/tcp
+```
+
+Don't forget to expose the kubernetes-worker application if its not already
+exposed, as this can cause confusion once the port has been opened and the
+service is not reachable.
+
+Note: When debugging connection issues with NodePort services, its important
+to first check the kube-proxy service on the worker units. If kube-proxy is not
+running, the associated port-mapping will not be configured in the iptables
+rulechains. 
+
+If you need to close the NodePort once a workload has been terminated, you can
+follow the same steps inversely.
+
+```
+juju run --application kubernetes-worker close-port 30510
+```
+

+description: |
+  Kubernetes is an open-source platform for deploying, scaling, and operations
+  of application containers across a cluster of hosts. Kubernetes is portable
+  in that it works with public, private, and hybrid clouds. Extensible through
+  a pluggable infrastructure. Self healing in that it will automatically
+  restart and place containers on healthy nodes if a node ever goes away.
