 ## How to become a contributor and submit your own code
 
-### Environment setup
-
-It is recommended to use filter to manage the GitHub email notification, see [examples for setting filters to Kubernetes Github notifications](https://github.com/kubernetes/community/blob/master/communication/best-practices.md#examples-for-setting-filters-to-kubernetes-github-notifications)
-
-To install development dependencies you can use `pip install -r tests/requirements.txt`
-
-#### Linting
-
-Kubespray uses `yamllint` and `ansible-lint`. To run them locally use `yamllint .` and `./tests/scripts/ansible-lint.sh`
-
-#### Molecule
-
-[molecule](https://github.com/ansible-community/molecule) is designed to help the development and testing of Ansible roles. In Kubespray you can run it all for all roles with `./tests/scripts/molecule_run.sh` or for a specific role (that you are working with) with `molecule test` from the role directory (`cd roles/my-role`).
-
-When developing or debugging a role it can be useful to run `molecule create` and `molecule converge` separately. Then you can use `molecule login` to SSH into the test environment.
-
-#### Vagrant
-
-Vagrant with VirtualBox or libvirt driver helps you to quickly spin test clusters to test things end to end. See [README.md#vagrant](README.md)
-
 ### Contributing A Patch
 
 1. Submit an issue describing your proposed change to the repo in question.
 2. The [repo owners](OWNERS) will respond to your issue promptly.
 3. Fork the desired repo, develop and test your code changes.

+# Deploy MetalLB into Kubespray/Kubernetes
+```
+MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type “LoadBalancer” in clusters that don’t run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers.
+```
+This playbook aims to automate [this](https://metallb.universe.tf/concepts/layer2/). It deploys MetalLB into kubernetes and sets up a layer 2 loadbalancer.
+
+## Install
+```
+Defaults can be found in contrib/metallb/roles/provision/defaults/main.yml. You can override the defaults by copying the contents of this file to somewhere in inventory/mycluster/group_vars such as inventory/mycluster/groups_vars/k8s-cluster/addons.yml and making any adjustments as required.

-### Configuration
-
-* `ingress_ambassador_namespace` (default `ambassador`): namespace for installing Ambassador.
-* `ingress_ambassador_update_window` (default `0 0 * * SUN`): _crontab_-like expression
-  for specifying when the Operator should try to update the Ambassador API Gateway.
-* `ingress_ambassador_version` (defaulkt: `*`): SemVer rule for versions allowed for
-  installation/updates.
-* `ingress_ambassador_secure_port` (default: 443): HTTPS port to listen at.
-* `ingress_ambassador_insecure_port` (default: 80): HTTP port to listen at.
-
-### Ambassador Operator
-
-This Ambassador addon deploys the Ambassador Operator, which in turn will install
-the [Ambassador API Gateway](https://github.com/datawire/ambassador) in
-a Kubernetes cluster.
-
-The Ambassador Operator is a Kubernetes Operator that controls Ambassador's complete lifecycle
-in your cluster, automating many of the repeatable tasks you would otherwise have to perform
-yourself.  Once installed, the Operator will complete installations and seamlessly upgrade to new
-versions of Ambassador as they become available.
-
-## Usage
-
-The following example creates simple http-echo services and an `Ingress` object
-to route to these services.
-
-Note well that the [Ambassador API Gateway](https://github.com/datawire/ambassador) will automatically load balance `Ingress` resources
-that include the annotation `kubernetes.io/ingress.class=ambassador`. All the other
-resources will be just ignored.
-
-```yaml
-kind: Pod
-apiVersion: v1
-metadata:
-  name: foo-app
-  labels:
-    app: foo
-spec:
-  containers:
-  - name: foo-app
-    image: hashicorp/http-echo
-    args:
-    - "-text=foo"
----
-kind: Service
-apiVersion: v1
-metadata:
-  name: foo-service
-spec:
-  selector:
-    app: foo
-  ports:
-  # Default port used by the image
-  - port: 5678
----
-apiVersion: extensions/v1beta1
-kind: Ingress
-metadata:
-  name: example-ingress
-  annotations:
-    kubernetes.io/ingress.class: ambassador
-spec:
-  rules:
-  - http:
-      paths:
-      - path: /foo
-        backend:
-          serviceName: foo-service
-          servicePort: 5678
-```
-
-Now you can test that the ingress is working with curl:
-
-```console
-$ export AMB_IP=$(kubectl get service ambassador -n ambassador -o 'go-template={{range .status.loadBalancer.ingress}}{{print .ip "\n"}}{{end}}')
-$ curl $AMB_IP/foo
-foo
-```

-# AWS EBS CSI Driver
-
-AWS EBS CSI driver allows you to provision EBS volumes for pods in EC2 instances. The old in-tree AWS cloud provider is deprecated and will be removed in future versions of Kubernetes. So transitioning to the CSI driver is advised.
-
-To enable AWS EBS CSI driver, uncomment the `aws_ebs_csi_enabled` option in `group_vars/all/aws.yml` and set it to `true`.
-
-To set the number of replicas for the AWS CSI controller, you can change `aws_ebs_csi_controller_replicas` option in `group_vars/all/aws.yml`.
-
-Make sure to add a role, for your EC2 instances hosting Kubernetes, that allows it to do the actions necessary to request a volume and attach it: [AWS CSI Policy](https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/master/docs/example-iam-policy.json)
-
-If you want to deploy the AWS EBS storage class used with the CSI Driver, you should set `persistent_volumes_enabled` in `group_vars/k8s-cluster/k8s-cluster.yml` to `true`.
-
-You can now run the kubespray playbook (cluster.yml) to deploy Kubernetes over AWS EC2 with EBS CSI Driver enabled.
-
-## Usage example
-
-To check if AWS EBS CSI Driver is deployed properly, check that the ebs-csi pods are running:
-
-```ShellSession
-$ kubectl -n kube-system get pods | grep ebs
-ebs-csi-controller-85d86bccc5-8gtq5                                  4/4     Running   4          40s
-ebs-csi-node-n4b99                                                   3/3     Running   3          40s
-```
-
-Check the associated storage class (if you enabled persistent_volumes):
-
-```ShellSession
-$ kubectl get storageclass
-NAME         PROVISIONER                AGE
-ebs-sc   ebs.csi.aws.com   45s
-```
-
-You can run a PVC and an example Pod using this file `ebs-pod.yml`:
-
-```yml
---
-apiVersion: v1
-kind: PersistentVolumeClaim
-metadata:
-  name: ebs-claim
-spec:
-  accessModes:
-    - ReadWriteOnce
-  storageClassName: ebs-sc

-      mountPath: /data
-  volumes:
-  - name: persistent-storage
-    persistentVolumeClaim:
-      claimName: ebs-claim
-```
-
-Apply this conf to your cluster: ```kubectl apply -f ebs-pod.yml```
-
-You should see the PVC provisioned and bound:
-
-```ShellSession
-$ kubectl get pvc
-NAME                   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE

-```
-
-And the volume mounted to the example Pod (wait until the Pod is Running):
-
-```ShellSession
-$ kubectl exec -it app -- df -h | grep data
-/dev/nvme1n1   1014M   34M  981M   4% /data

-## Kube-proxy replacement with Cilium
-
-Cilium can run without kube-proxy by setting `cilium_kube_proxy_replacement`
-to `strict`.
-
-Without kube-proxy, cilium needs to know the address of the kube-apiserver
-and this must be set globally for all cilium components (agents and operators).
-Hence, in this configuration in Kubespray, Cilium will always contact
-the external loadbalancer (even from a node in the control plane)
-and if there is no external load balancer It will ignore any local load
-balancer deployed by Kubespray and **only contacts the first master**.
