 ## 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 `ansible-lint`
-
-#### 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)
-

+# 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.

 This playbook aims to automate [this](https://github.com/heketi/heketi/blob/master/docs/admin/install-kubernetes.md) tutorial. It deploys heketi/glusterfs into kubernetes and sets up a storageclass.
 
-## Important notice
-
-> Due to resource limits on the current project maintainers and general lack of contributions we are considering placing Heketi into a [near-maintenance mode](https://github.com/heketi/heketi#important-notice)
-
 ## Client Setup
-
 Heketi provides a CLI that provides users with a means to administer the deployment and configuration of GlusterFS in Kubernetes. [Download and install the heketi-cli](https://github.com/heketi/heketi/releases) on your client machine.
 
 ## Install
-
 Copy the inventory.yml.sample over to inventory/sample/k8s_heketi_inventory.yml and change it according to your setup.
-
-```shell
+```
 ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi.yml
 ```
 
 ## Tear down
-
-```shell
+```
 ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi-tear-down.yml
 ```

-# Container image collecting script for offline deployment
-
-This script has two features:
-(1) Get container images from an environment which is deployed online.
-(2) Deploy local container registry and register the container images to the registry.
-
-Step(1) should be done online site as a preparation, then we bring the gotten images
-to the target offline environment.
-Then we will run step(2) for registering the images to local registry.
-
-Step(1) can be operated with:
-
-```shell
-manage-offline-container-images.sh   create
-```
-
-Step(2) can be operated with:
-
-```shell

-## Requirements
-
+**Requirements**
 - Terraform 0.12.0 or newer
 
-## How to Use
+**How to Use:**
 
 - Export the variables for your AWS credentials or edit `credentials.tfvars`:
 
-```commandline
+```
 export TF_VAR_AWS_ACCESS_KEY_ID="www"
 export TF_VAR_AWS_SECRET_ACCESS_KEY ="xxx"
 export TF_VAR_AWS_SSH_KEY_NAME="yyy"
 export TF_VAR_AWS_DEFAULT_REGION="zzz"
 ```
-
-- Update `contrib/terraform/aws/terraform.tfvars` with your data. By default, the Terraform scripts use Ubuntu 18.04 LTS (Bionic) as base image. If you want to change this behaviour, see note "Using other distrib than Ubuntu" below.
+- Update `contrib/terraform/aws/terraform.tfvars` with your data. By default, the Terraform scripts use CoreOS as base image. If you want to change this behaviour, see note "Using other distrib than CoreOs" below.
 - Create an AWS EC2 SSH Key
 - Run with `terraform apply --var-file="credentials.tfvars"` or `terraform apply` depending if you exported your AWS credentials
 
 Example:
-
 ```commandline
 terraform apply -var-file=credentials.tfvars
 ```
 
 - Terraform automatically creates an Ansible Inventory file called `hosts` with the created infrastructure in the directory `inventory`
+
 - Ansible will automatically generate an ssh config file for your bastion hosts. To connect to hosts with ssh using bastion host use generated ssh-bastion.conf.
   Ansible automatically detects bastion and changes ssh_args  
-
 ```commandline
 ssh -F ./ssh-bastion.conf user@$ip
 ```
 
 - Once the infrastructure is created, you can run the kubespray playbooks and supply inventory/hosts with the `-i` flag.
 
-Example (this one assumes you are using Ubuntu)

-## Connecting to Kubernetes
+**Troubleshooting**
 
-You can use the following set of commands to get the kubeconfig file from your newly created cluster. Before running the commands, make sure you are in the project's root folder.
-
-```commandline
-# Get the controller's IP address.
-CONTROLLER_HOST_NAME=$(cat ./inventory/hosts | grep "\[kube-master\]" -A 1 | tail -n 1)
-CONTROLLER_IP=$(cat ./inventory/hosts | grep $CONTROLLER_HOST_NAME | grep ansible_host | cut -d'=' -f2)
-
-# Get the hostname of the load balancer.
-LB_HOST=$(cat inventory/hosts | grep apiserver_loadbalancer_domain_name | cut -d'"' -f2)
-
-# Get the controller's SSH fingerprint.
-ssh-keygen -R $CONTROLLER_IP > /dev/null 2>&1
-ssh-keyscan -H $CONTROLLER_IP >> ~/.ssh/known_hosts 2>/dev/null
-
-# Get the kubeconfig from the controller.
-mkdir -p ~/.kube
-ssh -F ssh-bastion.conf centos@$CONTROLLER_IP "sudo chmod 644 /etc/kubernetes/admin.conf"
-scp -F ssh-bastion.conf centos@$CONTROLLER_IP:/etc/kubernetes/admin.conf ~/.kube/config
-sed -i "s^server:.*^server: https://$LB_HOST:6443^" ~/.kube/config
-kubectl get nodes
-```
-
-## Troubleshooting
-
-### Remaining AWS IAM Instance Profile
+***Remaining AWS IAM Instance Profile***:
 
 If the cluster was destroyed without using Terraform it is possible that
 the AWS IAM Instance Profiles still remain. To delete them you can use
 the `AWS CLI` with the following command:
-
-```commandline
+```
 aws iam delete-instance-profile --region <region_name> --instance-profile-name <profile_name>
 ```
 
-### Ansible Inventory doesn't get created
+***Ansible Inventory doesn't get created:***
 
 It could happen that Terraform doesn't create an Ansible Inventory file automatically. If this is the case copy the output after `inventory=` and create a file named `hosts`in the directory `inventory` and paste the inventory into the file.

-```
-
-## Requirements
-
-* Terraform 0.12.0 or newer
-
-## Quickstart
-
-To get a cluster up and running you'll need a JSON keyfile.
-Set the path to the file in the `tfvars.json` file and run the following:
-
-```bash
-terraform apply -var-file tfvars.json -state dev-cluster.tfstate -var gcp_project_id=<ID of your GCP project> -var keyfile_location=<location of the json keyfile>
-```
-
-To generate kubespray inventory based on the terraform state file you can run the following:
-
-```bash
-./generate-inventory.sh dev-cluster.tfstate > inventory.ini
-```
-
-You should now have a inventory file named `inventory.ini` that you can use with kubespray, e.g.
-
-```bash
-ansible-playbook -i contrib/terraform/gcs/inventory.ini cluster.yml -b -v
-```
-
-## Variables
-
-### Required
-
-* `keyfile_location`: Location to the keyfile to use as credentials for the google terraform provider
-* `gcp_project_id`: ID of the GCP project to deploy the cluster in
-* `ssh_pub_key`: Path to public ssh key to use for all machines
-* `region`: The region where to run the cluster
-* `machines`: Machines to provision. Key of this object will be used as the name of the machine
-  * `node_type`: The role of this node *(master|worker)*
-  * `size`: The size to use
-  * `zone`: The zone the machine should run in
-  * `additional_disks`: Extra disks to add to the machine. Key of this object will be used as the disk name
-    * `size`: Size of the disk (in GB)
-  * `boot_disk`: The boot disk to use
-    * `image_name`: Name of the image
-    * `size`: Size of the boot disk (in GB)
-* `ssh_whitelist`: List of IP ranges (CIDR) that will be allowed to ssh to the nodes
-* `api_server_whitelist`: List of IP ranges (CIDR) that will be allowed to connect to the API server
-* `nodeport_whitelist`: List of IP ranges (CIDR) that will be allowed to connect to the kubernetes nodes on port 30000-32767 (kubernetes nodeports)
-
-### Optional
-
-* `prefix`: Prefix to use for all resources, required to be unique for all clusters in the same project *(Defaults to `default`)*
-* `master_sa_email`: Service account email to use for the master nodes *(Defaults to `""`, auto generate one)*
-* `master_sa_scopes`: Service account email to use for the master nodes *(Defaults to `["https://www.googleapis.com/auth/cloud-platform"]`)*
-* `worker_sa_email`: Service account email to use for the worker nodes *(Defaults to `""`, auto generate one)*
-* `worker_sa_scopes`: Service account email to use for the worker nodes *(Defaults to `["https://www.googleapis.com/auth/cloud-platform"]`)*
-
-An example variables file can be found `tfvars.json`
-
-## Known limitations
-
-This solution does not provide a solution to use a bastion host. Thus all the nodes must expose a public IP for kubespray to work.
