# Contributing guidelines
## 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)
### 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.
4. Sign the CNCF CLA (<https://git.k8s.io/community/CLA.md#the-contributor-license-agreement>)
5. Submit a pull request.

# Deploy a Production Ready Kubernetes Cluster
vagrant-k8s
===========
Scripts to create libvirt lab with vagrant and prepare some stuff for `k8s` deployment with `kargo`.
![Kubernetes Logo](https://raw.githubusercontent.com/kubernetes-sigs/kubespray/master/docs/img/kubernetes-logo.png)
If you have questions, check the documentation at [kubespray.io](https://kubespray.io) and join us on the [kubernetes slack](https://kubernetes.slack.com), channel **\#kubespray**.
You can get your invite [here](http://slack.k8s.io/)
Requirements
============
- Can be deployed on **AWS, GCE, Azure, OpenStack, vSphere, Packet (bare metal), 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**
* `libvirt`
* `vagrant`
* `vagrant-libvirt` plugin
* `$USER` should be able to connect to libvirt (test with `virsh list --all`)
## Quick Start
How-to
======
To deploy the cluster you can use :
* Prepare the virtual lab:
### Ansible
#### Usage
```ShellSession
# Install dependencies from ``requirements.txt``
sudo pip3 install -r requirements.txt
# Copy ``inventory/sample`` as ``inventory/mycluster``
cp -rfp inventory/sample inventory/mycluster
# 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.yaml 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 `--become` 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
```
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.
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 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/>
Install the necessary requirements
```ShellSession
sudo pip install -r requirements.txt
```bash
export VAGRANT_POOL="10.100.0.0/16"
git clone https://github.com/adidenko/vagrant-k8s
cd vagrant-k8s
vagrant up
```

- [coredns](https://github.com/coredns/coredns) v1.6.5
- [ingress-nginx](https://github.com/kubernetes/ingress-nginx) v0.30.0
Note: The list of validated [docker versions](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.16.md) was updated to 1.13.1, 17.03, 17.06, 17.09, 18.06, 18.09. kubeadm now properly recognizes Docker 18.09.0 and newer, but still treats 18.06 as the default supported version. 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).
## Requirements
- **Minimum required version of Kubernetes is v1.15**
- **Ansible v2.9+, Jinja 2.11+ and python-netaddr is installed on the machine that will run Ansible commands**
- The target servers must have **access to the Internet** in order to pull docker images. Otherwise, additional configuration is required (See [Offline Environment](https://github.com/kubernetes-sigs/kubespray/blob/master/docs/downloads.md#offline-environment))
- The target servers are configured to allow **IPv4 forwarding**.
- **Your ssh key must be copied** to all the servers part of your inventory.
- 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.
- If kubespray is ran from non-root user account, correct privilege escalation method
should be configured in the target servers. Then the `ansible_become` flag
or command parameters `--become or -b` should be specified.
Hardware:
These limits are safe guarded by Kubespray. Actual requirements for your workload can differ. For a sizing guide go to the [Building Large Clusters](https://kubernetes.io/docs/setup/cluster-large/#size-of-master-and-master-components) guide.
- Master
- Memory: 1500 MB
- Node
- Memory: 1024 MB
## Network Plugins
You can choose between 10 network plugins. (default: `calico`, except Vagrant uses `flannel`)
- [flannel](docs/flannel.md): gre/vxlan (layer 2) networking.
- [Calico](https://docs.projectcalico.org/latest/introduction/) is a networking and network policy provider. Calico supports a flexible set of networking options
designed to give you the most efficient networking across a range of situations, including non-overlay
and overlay networks, with or without BGP. Calico uses the same engine to enforce network policy for hosts,
pods, and (if using Istio and Envoy) applications at the service mesh layer.
- [canal](https://github.com/projectcalico/canal): a composition of calico and flannel plugins.
- [cilium](http://docs.cilium.io/en/latest/): layer 3/4 networking (as well as layer 7 to protect and secure application protocols), supports dynamic insertion of BPF bytecode into the Linux kernel to implement security services, networking and visibility logic.
- [contiv](docs/contiv.md): supports vlan, vxlan, bgp and Cisco SDN networking. This plugin is able to
apply firewall policies, segregate containers in multiple network and bridging pods onto physical networks.
- [weave](docs/weave.md): Weave is a lightweight container overlay network that doesn't require an external K/V database cluster.
(Please refer to `weave` [troubleshooting documentation](https://www.weave.works/docs/net/latest/troubleshooting/)).
- [kube-ovn](docs/kube-ovn.md): Kube-OVN integrates the OVN-based Network Virtualization with Kubernetes. It offers an advanced Container Network Fabric for Enterprises.
- [kube-router](docs/kube-router.md): Kube-router is a L3 CNI for Kubernetes networking aiming to provide operational
simplicity and high performance: it uses IPVS to provide Kube Services Proxy (if setup to replace kube-proxy),
iptables for network policies, and BGP for ods L3 networking (with optionally BGP peering with out-of-cluster BGP peers).
It can also optionally advertise routes to Kubernetes cluster Pods CIDRs, ClusterIPs, ExternalIPs and LoadBalancerIPs.
- [macvlan](docs/macvlan.md): Macvlan is a Linux network driver. Pods have their own unique Mac and Ip address, connected directly the physical (layer 2) network.
- [multus](docs/multus.md): Multus is a meta CNI plugin that provides multiple network interface support to pods. For each interface Multus delegates CNI calls to secondary CNI plugins such as Calico, macvlan, etc.
The choice is defined with the variable `kube_network_plugin`. There is also an
option to leverage built-in cloud provider networking instead.
See also [Network checker](docs/netcheck.md).

# Release Process
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! | ...`
## Major/minor releases and milestones
* For major releases (vX.Y) Kubespray maintains one branch (`release-X.Y`). Minor releases (vX.Y.Z) are available only as tags.
* Security patches and bugs might be backported.
* Fixes for major releases (vX.Y) and minor releases (vX.Y.Z) 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
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`).
* There is no unstable releases and no APIs, thus Kubespray doesn't follow
[semver](https://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`,
then Kubespray v2.1.0 may be bound to only minor changes to `kube_version`, like v1.5.1
and *any* changes to other components, like etcd v4, or calico 1.2.3.
And Kubespray v3.x.x shall be bound to `kube_version: 2.x.x` respectively.

# Kubernetes on Azure with Azure Resource Group Templates
Provision the base infrastructure for a Kubernetes cluster by using [Azure Resource Group Templates](https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-authoring-templates)
## Status
This will provision the base infrastructure (vnet, vms, nics, ips, ...) needed for Kubernetes in Azure into the specified
Resource Group. It will not install Kubernetes itself, this has to be done in a later step by yourself (using kubespray of course).
## Requirements
- [Install azure-cli](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest)
- [Login with azure-cli](https://docs.microsoft.com/en-us/cli/azure/authenticate-azure-cli?view=azure-cli-latest)
- Dedicated Resource Group created in the Azure Portal or through azure-cli
## Configuration through group_vars/all
You have to modify at least two variables in group_vars/all. The one is the **cluster_name** variable, it must be globally
unique due to some restrictions in Azure. The other one is the **ssh_public_keys** variable, it must be your ssh public
key to access your azure virtual machines. Most other variables should be self explanatory if you have some basic Kubernetes
experience.
## Bastion host
You can enable the use of a Bastion Host by changing **use_bastion** in group_vars/all to **true**. The generated
templates will then include an additional bastion VM which can then be used to connect to the masters and nodes. The option
also removes all public IPs from all other VMs.
## Generating and applying
To generate and apply the templates, call:
```shell
$ ./apply-rg.sh <resource_group_name>
```
If you change something in the configuration (e.g. number of nodes) later, you can call this again and Azure will
take care about creating/modifying whatever is needed.
## Clearing a resource group
If you need to delete all resources from a resource group, simply call:
```shell
$ ./clear-rg.sh <resource_group_name>
```
**WARNING** this really deletes everything from your resource group, including everything that was later created by you!
## Generating an inventory for kubespray
After you have applied the templates, you can generate an inventory with this call:
```shell
$ ./generate-inventory.sh <resource_group_name>
```
It will create the file ./inventory which can then be used with kubespray, e.g.:
```shell
$ cd kubespray-root-dir
$ ansible-playbook -i contrib/azurerm/inventory -u devops --become -e "@inventory/sample/group_vars/all/all.yml" cluster.yml
```

# 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.

# Kubespray on KVM Virtual Machines hypervisor preparation
A simple playbook to ensure your system has the right settings to enable Kubespray
deployment on VMs.
This playbook does not create Virtual Machines, nor does it run Kubespray itself.
### User creation
If you want to create a user for running Kubespray deployment, you should specify
both `k8s_deployment_user` and `k8s_deployment_user_pkey_path`.

# 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 dont 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.
ansible-playbook --ask-become -i inventory/sample/hosts.ini contrib/metallb/metallb.yml
