+probably pointing on a task depending on a module present in requirements.txt (i.e. "unseal vault").
 
 One way of solving this would be to uninstall the Ansible package and then, to install it via pip but it is not always possible.
 A workaround consists of setting `ANSIBLE_LIBRARY` and `ANSIBLE_MODULE_UTILS` environment variables respectively to the `ansible/modules` and `ansible/module_utils` subdirectories of pip packages installation location, which can be found in the Location field of the output of `pip show [package]` before executing `ansible-playbook`.
 
-A simple way to ensure you get all the correct version of Ansible is to use the [pre-built docker image from Quay](https://quay.io/repository/kubespray/kubespray?tab=tags).
-You will then need to use [bind mounts](https://docs.docker.com/storage/bind-mounts/) to get the inventory and ssh key into the container, like this:
-
-```ShellSession
-docker pull quay.io/kubespray/kubespray:v2.15.1
-docker run --rm -it --mount type=bind,source="$(pwd)"/inventory/sample,dst=/inventory \
-  --mount type=bind,source="${HOME}"/.ssh/id_rsa,dst=/root/.ssh/id_rsa \
-  quay.io/kubespray/kubespray:v2.15.1 bash
-# Inside the container you may now run the kubespray playbooks:

The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).

+# 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.

 Finally, provision the glusterfs nodes and add the Persistent Volume setup for GlusterFS in Kubernetes through the following ansible call:
 
-```shell
+```
 ansible-playbook -b --become-user=root -i contrib/terraform/openstack/hosts ./contrib/network-storage/glusterfs/glusterfs.yml
 ```
 
 If you need to destroy the cluster, you can run:
 
-```shell
+```
 terraform destroy -state=contrib/terraform/openstack/terraform.tfstate -var-file=my-kubespray-gluster-cluster.tfvars contrib/terraform/openstack
 ```

 # Deploy Heketi/Glusterfs into Kubespray/Kubernetes
-
 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

-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
-manage-offline-container-images.sh   register
-```
-
-## generate_list.sh
-
-This script generates the list of downloaded files and the list of container images by `roles/download/defaults/main.yml` file.
-
-Run this script will generates three files, all downloaded files url in files.list, all container images in images.list, all component version in generate.sh.
-
-```shell
-bash generate_list.sh
-tree temp
-temp
-├── files.list
-├── generate.sh
-└── images.list
-0 directories, 3 files
-```
-
-In some cases you may want to update some component version, you can edit `generate.sh` file, then run `bash generate.sh | grep 'https' > files.list` to update file.list or run `bash generate.sh | grep -v 'https'> images.list` to update images.list.

-# Kubernetes on AWS with Terraform
+## Kubernetes on AWS with Terraform
 
-## Overview
+**Overview:**
 
 This project will create:
+* VPC with Public and Private Subnets in # Availability Zones
+* Bastion Hosts and NAT Gateways in the Public Subnet
+* A dynamic number of masters, etcd, and worker nodes in the Private Subnet
+ * even distributed over the # of Availability Zones
+* AWS ELB in the Public Subnet for accessing the Kubernetes API from the internet
 
-- VPC with Public and Private Subnets in # Availability Zones
+**Requirements**
-- Bastion Hosts and NAT Gateways in the Public Subnet
-- A dynamic number of masters, etcd, and worker nodes in the Private Subnet
-  - even distributed over the # of Availability Zones
-- AWS ELB in the Public Subnet for accessing the Kubernetes API from the internet
-
-## 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 CoreOS as base image. If you want to change this behaviour, see note "Using other distrib than CoreOs" below.
-- 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.
 - 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.
+***Remaining AWS IAM Instance Profile***:
-
-```commandline
-# Get the controller's IP address.
-CONTROLLER_HOST_NAME=$(cat ./inventory/hosts | grep "\[kube_control_plane\]" -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
 
 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 0.13.0 or newer
-
-*0.12 also works if you modify the provider block to include version and remove all `versions.tf` files*
-
-## Quickstart
-
-NOTE: *Assumes you are at the root of the kubespray repo*
-
-Copy the sample inventory for your cluster and copy the default terraform variables.
-
-```bash
-CLUSTER=my-exoscale-cluster
-cp -r inventory/sample inventory/$CLUSTER
-cp contrib/terraform/exoscale/default.tfvars inventory/$CLUSTER/
-cd inventory/$CLUSTER
-```
-
-Edit `default.tfvars` to match your setup. You MUST, at the very least, change `ssh_public_keys`.
-
-```bash
-# Ensure $EDITOR points to your favorite editor, e.g., vim, emacs, VS Code, etc.
-$EDITOR default.tfvars
-```
-
-For authentication you can use the credentials file `~/.cloudstack.ini` or `./cloudstack.ini`.
-The file should look like something like this:
-
-```ini
-[cloudstack]
-key = <API key>
-secret = <API secret>
-```
-
-Follow the [Exoscale IAM Quick-start](https://community.exoscale.com/documentation/iam/quick-start/) to learn how to generate API keys.
-
-### Encrypted credentials
-
-To have the credentials encrypted at rest, you can use [sops](https://github.com/mozilla/sops) and only decrypt the credentials at runtime.
-
-```bash
-cat << EOF > cloudstack.ini
-[cloudstack]
-key =
-secret =
-EOF
-sops --encrypt --in-place --pgp <PGP key fingerprint> cloudstack.ini
-sops cloudstack.ini
-```
-
-Run terraform to create the infrastructure
-
-```bash
-terraform init ../../contrib/terraform/exoscale
-terraform apply -var-file default.tfvars ../../contrib/terraform/exoscale
-```
-
-If your cloudstack credentials file is encrypted using sops, run the following:
-
-```bash
-terraform init ../../contrib/terraform/exoscale
-sops exec-file -no-fifo cloudstack.ini 'CLOUDSTACK_CONFIG={} terraform apply -var-file default.tfvars ../../contrib/terraform/exoscale'
-```
-
-You should now have a inventory file named `inventory.ini` that you can use with kubespray.
-You can now copy your inventory file and use it with kubespray to set up a cluster.
-You can type `terraform output` to find out the IP addresses of the nodes, as well as control-plane and data-plane load-balancer.
-
-It is a good idea to check that you have basic SSH connectivity to the nodes. You can do that by:
-
-```bash
-ansible -i inventory.ini -m ping all
-```
-
-Example to use this with the default sample inventory:
-
-```bash
-ansible-playbook -i inventory.ini ../../cluster.yml -b -v
-```
-
-## Teardown
-
-The Kubernetes cluster cannot create any load-balancers or disks, hence, teardown is as simple as Terraform destroy:
-
-```bash
-terraform destroy -var-file default.tfvars ../../contrib/terraform/exoscale
-```
-
-## Variables
-
-### Required
-
-* `ssh_public_keys`: List of public SSH keys to install on all machines
-* `zone`: The zone 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
-  * `boot_disk`: The boot disk to use
-    * `image_name`: Name of the image
-    * `root_partition_size`: Size *(in GB)* for the root partition
-    * `ceph_partition_size`: Size *(in GB)* for the partition for rook to use as ceph storage. *(Set to 0 to disable)*
-    * `node_local_partition_size`: Size *(in GB)* for the partition for node-local-storage. *(Set to 0 to disable)*
-* `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`)*
-
-An example variables file can be found `default.tfvars`
-
-## Known limitations
-
-### Only single disk
-
-Since Exoscale doesn't support additional disks to be mounted onto an instance, this script has the ability to create partitions for [Rook](https://rook.io/) and [node-local-storage](https://kubernetes.io/docs/concepts/storage/volumes/#local).
-
-### No Kubernetes API
-
-The current solution doesn't use the [Exoscale Kubernetes cloud controller](https://github.com/exoscale/exoscale-cloud-controller-manager).
-This means that we need to set up a HTTP(S) loadbalancer in front of all workers and set the Ingress controller to DaemonSet mode.
