 ## 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 set up a python virtual env with the necessary dependencies:
-
-```ShellSession
-virtualenv venv
-source venv/bin/activate
-pip install -r tests/requirements.txt
-ansible-galaxy install -r tests/requirements.yml
-```
-
-#### Linting
-
-Kubespray uses [pre-commit](https://pre-commit.com) hook configuration to run several linters, please install this tool and use it to run validation tests before submitting a PR.
-
-```ShellSession
-pre-commit install
-pre-commit run -a  # To run pre-commit hook on all files in the repository, even if they were not modified
-```
-
-#### 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.

+-   Can be deployed on **AWS, GCE, Azure, OpenStack, vSphere, Oracle Cloud Infrastructure (Experimental), or Baremetal**
+-   **Highly available** cluster
+-   **Composable** (Choice of the network plugin for instance)
+-   Supports most popular **Linux distributions**
+-   **Continuous integration tests**
 
-## Quick Start
+Quick Start
+-----------
 
-Below are several ways to use Kubespray to deploy a Kubernetes cluster.
+To deploy the cluster you can use :
 
-### Docker
-
-Ensure you have installed Docker then
-
-```ShellSession
-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:v2.29.0 bash
-# Inside the container you may now run the kubespray playbooks:
-ansible-playbook -i /inventory/inventory.ini --private-key /root/.ssh/id_rsa cluster.yml
-```
+### Current release
+2.8.2
 
 ### Ansible
 
+#### Ansible version
+
+Ansible v2.7.0 is failing and/or produce unexpected results due to [ansible/ansible/issues/46600](https://github.com/ansible/ansible/issues/46600)
+
 #### Usage
 
-See [Getting started](/docs/getting_started/getting-started.md)
+    # Install dependencies from ``requirements.txt``
+    sudo pip install -r requirements.txt
 
-#### Collection
+    # Copy ``inventory/sample`` as ``inventory/mycluster``
+    cp -rfp inventory/sample inventory/mycluster
 
-See [here](docs/ansible/ansible_collection.md) if you wish to use this repository as an Ansible collection
+    # Update Ansible inventory file with inventory builder
+    declare -a IPS=(10.10.1.3 10.10.1.4 10.10.1.5)
+    CONFIG_FILE=inventory/mycluster/hosts.ini python3 contrib/inventory_builder/inventory.py ${IPS[@]}
+
+    # Review and change parameters under ``inventory/mycluster/group_vars``
+    cat inventory/mycluster/group_vars/all/all.yml
+    cat inventory/mycluster/group_vars/k8s-cluster/k8s-cluster.yml
+
+    # Deploy Kubespray with Ansible Playbook - run the playbook as root
+    # The option `-b` is required, as for example writing SSL keys in /etc/,
+    # installing packages and interacting with various systemd daemons.
+    # Without -b the playbook will fail to run!
+    ansible-playbook -i inventory/mycluster/hosts.ini --become --become-user=root cluster.yml
+
+Note: When Ansible is already installed via system packages on the control machine, other python packages installed via `sudo pip install -r requirements.txt` will go to a different directory tree (e.g. `/usr/local/lib/python2.7/dist-packages` on Ubuntu) from Ansible's (e.g. `/usr/lib/python2.7/dist-packages/ansible` still on Ubuntu).
+As a consequence, `ansible-playbook` command will fail with:
+```
+ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.
+```
+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`.
 
 ### Vagrant
 
-For Vagrant we need to install Python dependencies for provisioning tasks.
-Check that ``Python`` and ``pip`` are installed:
+For Vagrant we need to install python dependencies for provisioning tasks.
+Check if Python and pip are installed:
 
-```ShellSession
-python -V && pip -V
-```
+    python -V && pip -V
 
 If this returns the version of the software, you're good to go. If not, download and install Python from here <https://www.python.org/downloads/source/>
+Install the necessary requirements
 
-Install Ansible according to [Ansible installation guide](/docs/ansible/ansible.md#installing-ansible)
-then run the following step:
+    sudo pip install -r requirements.txt
+    vagrant up
 
-```ShellSession
-vagrant up

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).

+* Kubespray does not maintain stable branches for releases. Releases are tags, not
+  branches, and there are no backports. Therefore, there is no need for merge
+  freezes as well.

+  [semver](http://semver.org/). Every version describes only a stable release.
   Breaking changes, if any introduced by changed defaults or non-contrib ansible roles'
   playbooks, shall be described in the release notes. Other breaking changes, if any in
   the contributed addons or bound versions of Kubernetes and other components, are
   considered out of Kubespray scope and are up to the components' teams to deal with and
   document.
 
-* Minor releases can change components' versions, but not the major `kube_version`.
-  Greater `kube_version` requires a new major or minor release. For example, if Kubespray v2.0.0
-  is bound to `kube_version: 1.4.x`, `calico_version: 0.22.0`, `etcd_version: 3.0.6`,

-## 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.
+  And Kubespray v3.x.x shall be bound to ``kube_version: 2.x.x`` respectively.

+# Kubespray DIND experimental setup
+
+This ansible playbook creates local docker containers
+to serve as Kubernetes "nodes", which in turn will run
+"normal" Kubernetes docker containers, a mode usually
+called DIND (Docker-IN-Docker).
+
+The playbook has two roles:
+- dind-host: creates the "nodes" as containers in localhost, with
+  appropriate settings for DIND (privileged, volume mapping for dind
+  storage, etc).
+- dind-cluster: customizes each node container to have required
+  system packages installed, and some utils (swapoff, lsattr)
+  symlinked to /bin/true to ease mimicking a real node.
+
+This playbook has been test with Ubuntu 16.04 as host and ubuntu:16.04
+as docker images (note that dind-cluster has specific customization
+for these images).
+
+The playbook also creates a `/tmp/kubespray.dind.inventory_builder.sh`
+helper (wraps up running `contrib/inventory_builder/inventory.py` with
+node containers IPs and prefix).
+
+## Deploying
+
+See below for a complete successful run:
+
+1. Create the node containers
+
+~~~~
+# From the kubespray root dir
+cd contrib/dind
+pip install -r requirements.txt
+
+ansible-playbook -i hosts dind-cluster.yaml
+
+# Back to kubespray root
+cd ../..
+~~~~
+
+NOTE: if the playbook run fails with something like below error
+message, you may need to specifically set `ansible_python_interpreter`,
+see `./hosts` file for an example expanded localhost entry.
+
+~~~
+failed: [localhost] (item=kube-node1) => {"changed": false, "item": "kube-node1", "msg": "Failed to import docker or docker-py - No module named requests.exceptions. Try `pip install docker` or `pip install docker-py` (Python 2.6)"}
+~~~
+
+2. Customize kubespray-dind.yaml
+
+Note that there's coupling between above created node containers
+and `kubespray-dind.yaml` settings, in particular regarding selected `node_distro`
+(as set in `group_vars/all/all.yaml`), and docker settings.
+
+~~~
+$EDITOR contrib/dind/kubespray-dind.yaml
+~~~
+
+3. Prepare the inventory and run the playbook
+
+~~~
+INVENTORY_DIR=inventory/local-dind
+mkdir -p ${INVENTORY_DIR}
+rm -f ${INVENTORY_DIR}/hosts.ini
+CONFIG_FILE=${INVENTORY_DIR}/hosts.ini /tmp/kubespray.dind.inventory_builder.sh
+
+ansible-playbook --become -e ansible_ssh_user=debian -i ${INVENTORY_DIR}/hosts.ini cluster.yml --extra-vars @contrib/dind/kubespray-dind.yaml
+~~~
+
+NOTE: You could also test other distros without editing files by
+passing `--extra-vars` as per below commandline,
+replacing `DISTRO` by either `debian`, `ubuntu`, `centos`, `fedora`:
+
+~~~
+cd contrib/dind
+ansible-playbook -i hosts dind-cluster.yaml --extra-vars node_distro=DISTRO
+
+cd ../..
+CONFIG_FILE=inventory/local-dind/hosts.ini /tmp/kubespray.dind.inventory_builder.sh
+ansible-playbook --become -e ansible_ssh_user=DISTRO -i inventory/local-dind/hosts.ini cluster.yml --extra-vars @contrib/dind/kubespray-dind.yaml --extra-vars bootstrap_os=DISTRO
+~~~
+
+## Resulting deployment
+
+See below to get an idea on how a completed deployment looks like,
+from the host where you ran kubespray playbooks.

+## Using ./run-test-distros.sh
+
+You can use `./run-test-distros.sh` to run a set of tests via DIND,
+and excerpt from this script, to get an idea:
+
+~~~
+# The SPEC file(s) must have two arrays as e.g.
+# DISTROS=(debian centos)
+# EXTRAS=(
+#     'kube_network_plugin=calico'
+#     'kube_network_plugin=flannel'
+#     'kube_network_plugin=weave'
+# )
+# that will be tested in a "combinatory" way (e.g. from above there'll be
+# be 6 test runs), creating a sequenced <spec_filename>-nn.out with each output.
+#
+# Each $EXTRAS element will be whitespace split, and passed as --extra-vars
+# to main kubespray ansible-playbook run.
+~~~
+
+See e.g. `test-some_distros-most_CNIs.env` and
+`test-some_distros-kube_router_combo.env` in particular for a richer
+set of CNI specific `--extra-vars` combo.

+
+### User creation

+# 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/tutorial/layer2/tutorial). It deploys MetalLB into kubernetes and sets up a layer 2 loadbalancer.
