 ## 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)
-

-# The option `--become` is required, as for example writing SSL keys in /etc/,
+    # The option `-b` is required, as for example writing SSL keys in /etc/,
     # installing packages and interacting with various systemd daemons.
-# Without --become the playbook will fail to run!
-ansible-playbook -i inventory/mycluster/hosts.yaml  --become --become-user=root cluster.yml
-```
+    # 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:
-
-```raw
+```
 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.

 For Vagrant we need to install python dependencies for provisioning tasks.
 Check if Python and pip are installed:
 
-```ShellSession
     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/>

 The Kubespray Project is released on an as-needed basis. The process is as follows:
 
 1. An issue is proposing a new release with a changelog since the last release
-2. At least one of the [approvers](OWNERS_ALIASES) must approve this release
-3. The `kube_version_min_required` variable is set to `n-1`
-4. Remove hashes for [EOL versions](https://github.com/kubernetes/sig-release/blob/master/releases/patch-releases.md) of kubernetes from `*_checksums` variables.
-5. An approver creates [new release in GitHub](https://github.com/kubernetes-sigs/kubespray/releases/new) using a version and tag name like `vX.Y.Z` and attaching the release notes
-6. An approver creates a release branch in the form `release-X.Y`
-7. The corresponding version of [quay.io/kubespray/kubespray:vX.Y.Z](https://quay.io/repository/kubespray/kubespray) and [quay.io/kubespray/vagrant:vX.Y.Z](https://quay.io/repository/kubespray/vagrant) docker images are built and tagged
-8. The `KUBESPRAY_VERSION` variable is updated in `.gitlab-ci.yml`
-9. The release issue is closed
-10. An announcement email is sent to `kubernetes-dev@googlegroups.com` with the subject `[ANNOUNCE] Kubespray $VERSION is released`
-11. The topic of the #kubespray channel is updated with `vX.Y.Z is released! | ...`
+2. At least one of the [OWNERS](OWNERS) must LGTM this release
+3. An OWNER runs `git tag -s $VERSION` and inserts the changelog and pushes the tag with `git push $VERSION`
+4. The release issue is closed
+5. An announcement email is sent to `kubernetes-dev@googlegroups.com` with the subject `[ANNOUNCE] Kubespray $VERSION is released`
 
-## Major/minor releases and milestones
+## Major/minor releases, merge freezes and milestones
 
-* For major releases (vX.Y) Kubespray maintains one branch (`release-X.Y`). Minor releases (vX.Y.Z) are available only as tags.
+* 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.
 
-* Security patches and bugs might be backported.
-
-* Fixes for major releases (vX.Y) and minor releases (vX.Y.Z) are delivered
+* Fixes for major releases (vX.x.0) and minor releases (vX.Y.x) are delivered
   via maintenance releases (vX.Y.Z) and assigned to the corresponding open
-  [GitHub milestone](https://github.com/kubernetes-sigs/kubespray/milestones).
-  That milestone remains open for the major/minor releases support lifetime,
-  which ends once the milestone is closed. Then only a next major or minor release
-  can be done.

-* Kubespray major and minor releases are bound to the given `kube_version` major/minor
+* Kubespray major and minor releases are bound to the given ``kube_version`` major/minor
   version numbers and other components' arbitrary versions, like etcd or network plugins.
-  Older or newer component versions are not supported and not tested for the given
-  release (even if included in the checksum variables, like `kubeadm_checksums`).
+  Older or newer versions are not supported and not tested for the given release.

+  [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: v3.0.6`,

 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.

-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.

-# Kubernetes on Packet with Terraform
-
-Provision a Kubernetes cluster with [Terraform](https://www.terraform.io) on
-[Packet](https://www.packet.com).
-
-## Status
-
-This will install a Kubernetes cluster on Packet bare metal. It should work in all locations and on most server types.
-
-## Approach
-The terraform configuration inspects variables found in
-[variables.tf](variables.tf) to create resources in your Packet project.
-There is a [python script](../terraform.py) that reads the generated`.tfstate`
-file to generate a dynamic inventory that is consumed by [cluster.yml](../../..//cluster.yml)
-to actually install Kubernetes with Kubespray.
-
-### Kubernetes Nodes
-You can create many different kubernetes topologies by setting the number of
-different classes of hosts.
-- Master nodes with etcd: `number_of_k8s_masters` variable
-- Master nodes without etcd: `number_of_k8s_masters_no_etcd` variable
-- Standalone etcd hosts: `number_of_etcd` variable
-- Kubernetes worker nodes: `number_of_k8s_nodes` variable
-
-Note that the Ansible script will report an invalid configuration if you wind up
-with an *even number* of etcd instances since that is not a valid configuration. This
-restriction includes standalone etcd nodes that are deployed in a cluster along with
-master nodes with etcd replicas. As an example, if you have three master nodes with
-etcd replicas and three standalone etcd nodes, the script will fail since there are
-now six total etcd replicas.
-
-## Requirements
-
-- [Install Terraform](https://www.terraform.io/intro/getting-started/install.html)
-- Install dependencies: `sudo pip install -r requirements.txt`
-- Account with Packet Host
-- An SSH key pair
-
-## SSH Key Setup
-
-An SSH keypair is required so Ansible can access the newly provisioned nodes (bare metal Packet hosts). By default, the public SSH key defined in cluster.tfvars will be installed in authorized_key on the newly provisioned nodes (~/.ssh/id_rsa.pub). Terraform will upload this public key and then it will be distributed out to all the nodes. If you have already set this public key in Packet (i.e. via the portal), then set the public keyfile name in cluster.tfvars to blank to prevent the duplicate key from being uploaded which will cause an error.
-
-If you don't already have a keypair generated (~/.ssh/id_rsa and ~/.ssh/id_rsa.pub), then a new keypair can be generated with the command:
-
-```ShellSession
-ssh-keygen -f ~/.ssh/id_rsa
-```
-
-## Terraform
-Terraform will be used to provision all of the Packet resources with base software as appropriate.
-
-### Configuration
-
-#### Inventory files
-
-Create an inventory directory for your cluster by copying the existing sample and linking the `hosts` script (used to build the inventory based on Terraform state):
-
-```ShellSession
-$ cp -LRp contrib/terraform/packet/sample-inventory inventory/$CLUSTER
-$ cd inventory/$CLUSTER
-$ ln -s ../../contrib/terraform/packet/hosts
-```
-
-This will be the base for subsequent Terraform commands.
-
-#### Packet API access
-
-Your Packet API key must be available in the `PACKET_AUTH_TOKEN` environment variable.
-This key is typically stored outside of the code repo since it is considered secret.
-If someone gets this key, they can startup/shutdown hosts in your project!
-
-For more information on how to generate an API key or find your project ID, please see:
-https://support.packet.com/kb/articles/api-integrations
-
-The Packet Project ID associated with the key will be set later in cluster.tfvars.
-
-For more information about the API, please see:
-https://www.packet.com/developers/api/
-
-Example:
-```ShellSession
-$ export PACKET_AUTH_TOKEN="Example-API-Token"
-```
-
-Note that to deploy several clusters within the same project you need to use [terraform workspace](https://www.terraform.io/docs/state/workspaces.html#using-workspaces).
-
-#### Cluster variables
-The construction of the cluster is driven by values found in
-[variables.tf](variables.tf).
-
-For your cluster, edit `inventory/$CLUSTER/cluster.tfvars`.
-
-The `cluster_name` is used to set a tag on each server deployed as part of this cluster.
-This helps when identifying which hosts are associated with each cluster.
-
-While the defaults in variables.tf will successfully deploy a cluster, it is recommended to set the following values:
-
-* cluster_name = the name of the inventory directory created above as $CLUSTER
-* packet_project_id = the Packet Project ID associated with the Packet API token above
-
-#### Enable localhost access
-Kubespray will pull down a Kubernetes configuration file to access this cluster by enabling the 
-`kubeconfig_localhost: true` in the Kubespray configuration.
-
-Edit `inventory/$CLUSTER/group_vars/k8s-cluster/k8s-cluster.yml` and comment back in the following line and change from `false` to `true`:
-`\# kubeconfig_localhost: false`
-becomes:
-`kubeconfig_localhost: true`
-
-Once the Kubespray playbooks are run, a Kubernetes configuration file will be written to the local host at `inventory/$CLUSTER/artifacts/admin.conf`
-
-#### Terraform state files
-
-In the cluster's inventory folder, the following files might be created (either by Terraform
-or manually), to prevent you from pushing them accidentally they are in a
-`.gitignore` file in the `terraform/packet` directory :
-
-* `.terraform`
-* `.tfvars`
-* `.tfstate`
-* `.tfstate.backup`
-
-You can still add them manually if you want to.
-
-### Initialization
-
-Before Terraform can operate on your cluster you need to install the required
-plugins. This is accomplished as follows:
-
-```ShellSession
-$ cd inventory/$CLUSTER
-$ terraform init ../../contrib/terraform/packet
-```
-
-This should finish fairly quickly telling you Terraform has successfully initialized and loaded necessary modules.
-
-### Provisioning cluster
-You can apply the Terraform configuration to your cluster with the following command
-issued from your cluster's inventory directory (`inventory/$CLUSTER`):
-```ShellSession
-$ terraform apply -var-file=cluster.tfvars ../../contrib/terraform/packet
-$ export ANSIBLE_HOST_KEY_CHECKING=False
-$ ansible-playbook -i hosts ../../cluster.yml
-```
-
-### Destroying cluster
-You can destroy your new cluster with the following command issued from the cluster's inventory directory:
-
-```ShellSession
-$ terraform destroy -var-file=cluster.tfvars ../../contrib/terraform/packet
-```
-
-If you've started the Ansible run, it may also be a good idea to do some manual cleanup:
-
-* remove SSH keys from the destroyed cluster from your `~/.ssh/known_hosts` file
-* clean up any temporary cache files: `rm /tmp/$CLUSTER-*`
-
-### Debugging
-You can enable debugging output from Terraform by setting `TF_LOG` to `DEBUG` before running the Terraform command.
-
-## Ansible
-
-### Node access
-
-#### SSH
-
-Ensure your local ssh-agent is running and your ssh key has been added. This
-step is required by the terraform provisioner:
-
-```
-$ eval $(ssh-agent -s)
-$ ssh-add ~/.ssh/id_rsa
-```
-
-If you have deployed and destroyed a previous iteration of your cluster, you will need to clear out any stale keys from your SSH "known hosts" file ( `~/.ssh/known_hosts`).
-
-#### Test access
-
-Make sure you can connect to the hosts.  Note that Container Linux by CoreOS will have a state `FAILED` due to Python not being present.  This is okay, because Python will be installed during bootstrapping, so long as the hosts are not `UNREACHABLE`.
-
-```
-$ ansible -i inventory/$CLUSTER/hosts -m ping all
-example-k8s_node-1 | SUCCESS => {
-    "changed": false,
-    "ping": "pong"
-}
-example-etcd-1 | SUCCESS => {
-    "changed": false,
-    "ping": "pong"
-}
-example-k8s-master-1 | SUCCESS => {
-    "changed": false,
-    "ping": "pong"
-}
-```
-
-If it fails try to connect manually via SSH.  It could be something as simple as a stale host key.
-
-### Deploy Kubernetes
-
-```
-$ ansible-playbook --become -i inventory/$CLUSTER/hosts cluster.yml
-```
-
-This will take some time as there are many tasks to run.
-
-## Kubernetes
-
-### Set up kubectl
-
-* [Install kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/) on the localhost.
-
-* Verify that Kubectl runs correctly
-```
-kubectl version
-```
-
-* Verify that the Kubernetes configuration file has been copied over
-```
-cat inventory/alpha/$CLUSTER/admin.conf
-```
-
-* Verify that all the nodes are running correctly.
-```
-kubectl version
-kubectl --kubeconfig=inventory/$CLUSTER/artifacts/admin.conf  get nodes
-```
-
-## What's next
-
-Try out your new Kubernetes cluster with the [Hello Kubernetes service](https://kubernetes.io/docs/tasks/access-application-cluster/service-access-application-cluster/).
