 ## 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 kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning).

-Allows a custom defintion of worker nodes giving the operator full control over individual node flavor and

-`number_of_k8s_nodes_no_floating_ip` variables to 0. Then define your desired worker node configuration

-# AWS EBS CSI Driver
-
-AWS EBS CSI driver allows you to provision EBS volumes for pods in EC2 instances. The old in-tree AWS cloud provider is deprecated and will be removed in future versions of Kubernetes. So transitioning to the CSI driver is advised.
-
-To enable AWS EBS CSI driver, uncomment the `aws_ebs_csi_enabled` option in `group_vars/all/aws.yml` and set it to `true`.
-
-To set the number of replicas for the AWS CSI controller, you can change `aws_ebs_csi_controller_replicas` option in `group_vars/all/aws.yml`.
-
-Make sure to add a role, for your EC2 instances hosting Kubernetes, that allows it to do the actions necessary to request a volume and attach it: [AWS CSI Policy](https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/master/docs/example-iam-policy.json)
-
-If you want to deploy the AWS EBS storage class used with the CSI Driver, you should set `persistent_volumes_enabled` in `group_vars/k8s-cluster/k8s-cluster.yml` to `true`.
-
-You can now run the kubespray playbook (cluster.yml) to deploy Kubernetes over AWS EC2 with EBS CSI Driver enabled.
-
-## Usage example
-
-To check if AWS EBS CSI Driver is deployed properly, check that the ebs-csi pods are running:
-
-```ShellSession
-$ kubectl -n kube-system get pods | grep ebs
-ebs-csi-controller-85d86bccc5-8gtq5                                  4/4     Running   4          40s
-ebs-csi-node-n4b99                                                   3/3     Running   3          40s
-```
-
-Check the associated storage class (if you enabled persistent_volumes):
-
-```ShellSession
-$ kubectl get storageclass
-NAME         PROVISIONER                AGE
-ebs-sc   ebs.csi.aws.com   45s
-```
-
-You can run a PVC and an example Pod using this file `ebs-pod.yml`:
-
-```yml
---
-apiVersion: v1
-kind: PersistentVolumeClaim
-metadata:
-  name: ebs-claim
-spec:
-  accessModes:
-    - ReadWriteOnce
-  storageClassName: ebs-sc
-  resources:
-    requests:
-      storage: 1Gi

-    args: ["-c", "while true; do echo $(date -u) >> /data/out.txt; sleep 5; done"]
-    volumeMounts:
-    - name: persistent-storage
-      mountPath: /data
-  volumes:
-  - name: persistent-storage
-    persistentVolumeClaim:
-      claimName: ebs-claim
-```
-
-Apply this conf to your cluster: ```kubectl apply -f ebs-pod.yml```
-
-You should see the PVC provisioned and bound:
-
-```ShellSession
-$ kubectl get pvc
-NAME                   STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
-ebs-claim   Bound    pvc-0034cb9e-1ddd-4b3f-bb9e-0b5edbf5194c   1Gi        RWO            ebs-sc         50s
-```
-
-And the volume mounted to the example Pod (wait until the Pod is Running):
-
-```ShellSession
-$ kubectl exec -it app -- df -h | grep data
-/dev/nvme1n1   1014M   34M  981M   4% /data
-```

 On caching:
 
 * When `download_run_once` is `True`, all downloaded files will be cached locally in `download_cache_dir`, which defaults to `/tmp/kubespray_cache`. On subsequent provisioning runs, this local cache will be used to provision the nodes, minimizing bandwidth usage and improving provisioning time. Expect about 800MB of disk space to be used on the ansible node for the cache. Disk space required for the image cache on the kubernetes nodes is a much as is needed for the largest image, which is currently slightly less than 150MB.
-* By default, if `download_run_once` is false, kubespray will not retrieve the downloaded images and files from the download delegate node to the local cache, or use that cache to pre-provision those nodes. If you have a full cache with container images and files and you don’t need to download anything, but want to use a cache - set `download_force_cache` to `True`.
-* By default, cached images that are used to pre-provision the remote nodes will be deleted from the remote nodes after use, to save disk space. Setting `download_keep_remote_cache` will prevent the files from being deleted. This can be useful while developing kubespray, as it can decrease provisioning times.

-
-The GCP Persistent Disk CSI driver allows you to provision volumes for pods with a Kubernetes deployment over Google Cloud Platform. The CSI driver replaces to volume provioning done by the in-tree azure cloud provider which is deprecated.

-
-Follow these steps to configure it:
-
-```ShellSession
-# This will open a web page for you to authenticate

-The above will create a file named `cloud-sa.json` in the specified `GCE_PD_SA_DIR`. This file contains the service account with the appropriate credentials for the CSI driver to perform actions on GCP to request disks for pods.
-
-You need to provide this file's path through the variable `gcp_pd_csi_sa_cred_file` in `inventory/mycluster/group_vars/all/gcp.yml`

-- Proxy URL is <http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#/login>
-- kubectl commands must be run with "-n kube-system"
+Or you can run 'kubectl proxy' from your local machine to access dashboard in your browser from:
+<http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login>
 
-Accessing through Ingress is highly recommended. For proxy access, please note that proxy must listen to [localhost](https://github.com/kubernetes/dashboard/issues/692#issuecomment-220492484) (`proxy  --address="x.x.x.x"` will not work)
-
-For token authentication, guide to create Service Account is provided in [dashboard sample user](https://github.com/kubernetes/dashboard/blob/master/docs/user/access-control/creating-sample-user.md) doc. Still take care of default namespace.

-Modified from [comments in #3471](https://github.com/kubernetes-sigs/kubespray/issues/3471#issuecomment-530036084)
-
-## Adding/replacing a worker node
-
-This should be the easiest.
-
-### 1) Add new node to the inventory
-
-### 2) Run `scale.yml`
-
-You can use `--limit=node1` to limit Kubespray to avoid disturbing other nodes in the cluster.
-
-Before using `--limit` run playbook `facts.yml` without the limit to refresh facts cache for all nodes.
-
-### 3) Drain the node that will be removed
-
-```sh
-kubectl drain NODE_NAME
-```
-
-### 4) Run the remove-node.yml playbook
-
-With the old node still in the inventory, run `remove-node.yml`. You need to pass `-e node=NODE_NAME` to the playbook to limit the execution to the node being removed.
-
-### 5) Remove the node from the inventory
-
-That's it.
-
-## Adding/replacing a master node
-
-### 1) Recreate apiserver certs manually to include the new master node in the cert SAN field
-
-For some reason, Kubespray will not update the apiserver certificate.
-
-Edit `/etc/kubernetes/kubeadm-config.yaml`, include new host in `certSANs` list.
-
-Use kubeadm to recreate the certs.
-
-```sh
-cd /etc/kubernetes/ssl
-mv apiserver.crt apiserver.crt.old
-mv apiserver.key apiserver.key.old
-
-cd /etc/kubernetes
-kubeadm init phase certs apiserver --config kubeadm-config.yaml
-```
-
-Check the certificate, new host needs to be there.
-
-```sh
-openssl x509 -text -noout -in /etc/kubernetes/ssl/apiserver.crt
-```
-
-### 2) Run `cluster.yml`
-
-Add the new host to the inventory and run cluster.yml.
-
-### 3) Restart kube-system/nginx-proxy
-
-In all hosts, restart nginx-proxy pod. This pod is a local proxy for the apiserver. Kubespray will update its static config, but it needs to be restarted in order to reload.
-
-```sh
-# run in every host
-docker ps | grep k8s_nginx-proxy_nginx-proxy | awk '{print $1}' | xargs docker restart
-```
-
-### 4) Remove old master nodes
-
-If you are replacing a node, remove the old one from the inventory, and remove from the cluster runtime.
-
-```sh
-kubectl drain NODE_NAME
-kubectl delete node NODE_NAME
-```
-
-After that, the old node can be safely shutdown. Also, make sure to restart nginx-proxy in all remaining nodes (step 3)
-
-From any active master that remains in the cluster, re-upload `kubeadm-config.yaml`
-
-```sh
-kubeadm config upload from-file --config /etc/kubernetes/kubeadm-config.yaml
-```
-
-## Adding/Replacing an etcd node
-
-You need to make sure there are always an odd number of etcd nodes in the cluster. In such a way, this is always a replace or scale up operation. Either add two new nodes or remove an old one.
-
-### 1) Add the new node running cluster.yml
-
-Update the inventory and run `cluster.yml` passing `--limit=etcd,kube-master -e ignore_assert_errors=yes`.
-
-Run `upgrade-cluster.yml` also passing `--limit=etcd,kube-master -e ignore_assert_errors=yes`. This is necessary to update all etcd configuration in the cluster.
-
-At this point, you will have an even number of nodes. Everything should still be working, and you should only have problems if the cluster decides to elect a new etcd leader before you remove a node. Even so, running applications should continue to be available.
-
-### 2) Remove an old etcd node
-
-With the node still in the inventory, run `remove-node.yml` passing `-e node=NODE_NAME` as the name of the node that should be removed.
-
-### 3) Make sure the remaining etcd members have their config updated
-
-In each etcd host that remains in the cluster:
-
-```sh
-cat /etc/etcd.env | grep ETCD_INITIAL_CLUSTER
-```
-
-Only active etcd members should be in that list.
-
-### 4) Remove old etcd members from the cluster runtime
-
-Acquire a shell prompt into one of the etcd containers and use etcdctl to remove the old member.
-
-```sh
-# list all members
-etcdctl member list
-
-# remove old member
-etcdctl member remove MEMBER_ID
-# careful!!! if you remove a wrong member you will be in trouble
-
-# note: these command lines are actually much bigger, since you need to pass all certificates to etcdctl.
-```
-
-### 5) Make sure the apiserver config is correctly updated
-
-In every master node, edit `/etc/kubernetes/manifests/kube-apiserver.yaml`. Make sure only active etcd nodes are still present in the apiserver command line parameter `--etcd-servers=...`.

 First you will need the ids of your OpenStack instances that will run kubernetes:
 
-  ```bash
     openstack server list --project YOUR_PROJECT
     +--------------------------------------+--------+----------------------------------+--------+-------------+
     | ID                                   | Name   | Tenant ID                        | Status | Power State |

-  ```
 
 Then you can use the instance ids to find the connected [neutron](https://wiki.openstack.org/wiki/Neutron) ports (though they are now configured through using OpenStack):
 
-  ```bash
     openstack port list -c id -c device_id --project YOUR_PROJECT
     +--------------------------------------+--------------------------------------+
     | id                                   | device_id                            |

-  ```
 
 Given the port ids on the left, you can set the two `allowed-address`(es) in OpenStack. Note that you have to allow both `kube_service_addresses` (default `10.233.0.0/18`) and `kube_pods_subnet` (default `10.233.64.0/18`.)
 
-  ```bash
     # allow kube_service_addresses and kube_pods_subnet network
     openstack port set 5662a4e0-e646-47f0-bf88-d80fbd2d99ef --allowed-address ip-address=10.233.0.0/18 --allowed-address ip-address=10.233.64.0/18
     openstack port set e5ae2045-a1e1-4e99-9aac-4353889449a7 --allowed-address ip-address=10.233.0.0/18 --allowed-address ip-address=10.233.64.0/18
-  ```
 
 If all the VMs in the tenant correspond to kubespray deployment, you can "sweep run" above with:
 
-  ```bash
     openstack port list --device-owner=compute:nova -c ID -f value | xargs -tI@ openstack port set @ --allowed-address ip-address=10.233.0.0/18 --allowed-address ip-address=10.233.64.0/18
-  ```
 
 Now you can finally run the playbook.

-Upgrade from the in-tree to the external cloud provider
----------------
-
-The in-tree cloud provider is deprecated and will be removed in a future version of Kubernetes. The target release for removing all remaining in-tree cloud providers is set to 1.21
-
-The new cloud provider is configured to have Octavia by default in Kubespray.
-
-- Change cloud provider from `cloud_provider: openstack` to the new external Cloud provider:
-
-  ```yaml
-  cloud_provider: external
-  external_cloud_provider: openstack
-  ```
-
-- Enable Cinder CSI:
-
-  ```yaml
-  cinder_csi_enabled: true
-  ```
-
-- Enable topology support (optional), if your openstack provider has custom Zone names you can override the default "nova" zone by setting the variable `cinder_topology_zones`
-
-  ```yaml
-  cinder_topology: true
-  ```
-
-- If you are using OpenStack loadbalancer(s) replace the `openstack_lbaas_subnet_id` with the new `external_openstack_lbaas_subnet_id`. **Note** The new cloud provider is using Octavia instead of Neutron LBaaS by default!
-- Enable 3 feature gates to allow migration of all volumes and storage classes (if you have any feature gates already set just add the 3 listed below):
-
-  ```yaml
-  kube_feature_gates:
-  - CSIMigration=true
-  - CSIMigrationOpenStack=true
-  - ExpandCSIVolumes=true
-  ```
-
-- Run the `upgrade-cluster.yml` playbook
-- Run the cleanup playbook located under extra_playbooks `extra_playbooks/migrate_openstack_provider.yml` (this will clean up all resources used by the old cloud provider)
-- You can remove the feature gates for Volume migration. If you want to enable the possibility to expand CSI volumes you could leave the `ExpandCSIVolumes=true` feature gate

-## Out-of-tree vSphere cloud provider
-
-### Prerequisites
-
-You need at first to configure your vSphere environment by following the [official documentation](https://github.com/kubernetes/cloud-provider-vsphere/blob/master/docs/book/tutorials/kubernetes-on-vsphere-with-kubeadm.md#prerequisites).
-
-After this step you should have:
-
-- vSphere upgraded to 6.7 U3 or later
-- VM hardware upgraded to version 15 or higher
-- UUID activated for each VM where Kubernetes will be deployed
-
-### Kubespray configuration
-
-First in `inventory/sample/group_vars/all.yml` you must set the cloud provider to `external` and external_cloud_provider to `external_cloud_provider`.
-
-```yml
-cloud_provider:  "external"
-external_cloud_provider: "vsphere"
-```
-
-Then, `inventory/sample/group_vars/vsphere.yml`, you need to declare your vCenter credentials and enable the vSphere CSI following the description below.
