+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

-- The list of available docker version is 18.09, 19.03 and 20.10. The recommended docker version is 20.10. 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).
-- The cri-o version should be aligned with the respective kubernetes version (i.e. kube_version=1.20.x, crio_version=1.20)

-- **Ansible v2.11+, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands**
+- **Minimum required version of Kubernetes is v1.18**
+- **Ansible v2.9.x, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands, Ansible 2.10.x is not supported for now**
 - The target servers must have **access to the Internet** in order to pull docker images. Otherwise, additional configuration is required (See [Offline Environment](docs/offline-environment.md))
 - The target servers are configured to allow **IPv4 forwarding**.
-- If using IPv6 for pods and services, the target servers are configured to allow **IPv6 forwarding**.
 - The **firewalls are not managed**, you'll need to implement your own rules the way you used to.
     in order to avoid any issue during deployment you should disable your firewall.

-## Release note creation
-
-You can create a release note with:
-
-```shell
-export GITHUB_TOKEN=<your-github-token>
-export ORG=kubernetes-sigs
-export REPO=kubespray
-release-notes --start-sha <The start commit-id> --end-sha <The end commit-id> --dependencies=false --output=/tmp/kubespray-release-note --required-author=""
-```

-If the release note file(/tmp/kubespray-release-note) contains "### Uncategorized" pull requests, those pull requests don't have a valid kind label(`kind/feature`, etc.).
-It is necessary to put a valid label on each pull request and run the above release-notes command again to get a better release note)
-
-## Container image creation
-
-The container image `quay.io/kubespray/kubespray:vX.Y.Z` can be created from Dockerfile of the kubespray root directory:
-
-```shell
-cd kubespray/
-nerdctl build -t quay.io/kubespray/kubespray:vX.Y.Z .
-nerdctl push quay.io/kubespray/kubespray:vX.Y.Z
-```
-
-The container image `quay.io/kubespray/vagrant:vX.Y.Z` can be created from build.sh of test-infra/vagrant-docker/:
-
-```shell
-cd kubespray/test-infra/vagrant-docker/
-./build vX.Y.Z
-```
-
-Please note that the above operation requires the permission to push container images into quay.io/kubespray/.
-If you don't have the permission, please ask it on the #kubespray-dev channel.

 For GlusterFS to connect between servers, TCP ports `24007`, `24008`, and `24009`/`49152`+ (that port, plus an additional incremented port for each additional server in the cluster; the latter if GlusterFS is version 3.4+), and TCP/UDP port `111` must be open. You can open these using whatever firewall you wish (this can easily be configured using the `geerlingguy.firewall` role).
 
-This role performs basic installation and setup of Gluster, but it does not configure or mount bricks (volumes), since that step is easier to do in a series of plays in your own playbook. Ansible 1.9+ includes the [`gluster_volume`](https://docs.ansible.com/ansible/latest/collections/gluster/gluster/gluster_volume_module.html) module to ease the management of Gluster volumes.

 Available variables are listed below, along with default values (see `defaults/main.yml`):
 
-```yaml
-glusterfs_default_release: ""
-```
+    glusterfs_default_release: ""
 
 You can specify a `default_release` for apt on Debian/Ubuntu by overriding this variable. This is helpful if you need a different package or version for the main GlusterFS packages (e.g. GlusterFS 3.5.x instead of 3.2.x with the `wheezy-backports` default release on Debian Wheezy).

-glusterfs_ppa_version: "3.5"
-```
+    glusterfs_ppa_use: yes
+    glusterfs_ppa_version: "3.5"
 
 For Ubuntu, specify whether to use the official Gluster PPA, and which version of the PPA to use. See Gluster's [Getting Started Guide](https://docs.gluster.org/en/latest/Quick-Start-Guide/Quickstart/) for more info.

-
-## 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.
