# This could be re-enabled with a major rewrite in the future.
# For now, there's not enough value gain from strictly limiting line length.

# [E701]: "meta/main.yml should contain relevant info"
# Roles in Kubespray are not intended to be used/imported by Ansible Galaxy.
# While it can be useful to have these metadata available, they are also available in the existing documentation.
# (Disabled in May 2019)
- '701'
# [role-name] "meta/main.yml" Role name role-name does not match ``^+$`` pattern
# Meta roles in Kubespray don't need proper names
# (Disabled in June 2021)
- 'role-name'
# [var-naming] "defaults/main.yml" File defines variable 'apiVersion' that violates variable naming standards
# In Kubespray we use variables that use camelCase to match their k8s counterparts

# 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 set up a python virtual env with the necessary dependencies:
```ShellSession
virtualenv venv
source venv/bin/activate
pip install -r tests/requirements.txt
```
#### 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.
4. Install [pre-commit](https://pre-commit.com) and install it in your development repo.
5. Addess any pre-commit validation failures.
6. Sign the CNCF CLA (<https://git.k8s.io/community/CLA.md#the-contributor-license-agreement>)
7. Submit a pull request.
8. Work with the reviewers on their suggestions.
9. Ensure to rebase to the HEAD of your target branch and squash un-necessary commits (<https://blog.carbonfive.com/always-squash-and-rebase-your-git-commits/>) before final merger of your contribution.

# Deploy a Production Ready Kubernetes Cluster
![Kubernetes Logo](https://raw.githubusercontent.com/kubernetes-sigs/kubespray/master/docs/img/kubernetes-logo.png)
![Kubespray Logo](http://s9.postimg.org/md5dyjl67/kubespray_logoandkubespray_small.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/)
The documentation can be found [THERE](https://docs.kubespray.io)
- Can be deployed on **[AWS](docs/aws.md), GCE, [Azure](docs/azure.md), [OpenStack](docs/openstack.md), [vSphere](docs/vsphere.md), [Equinix Metal](docs/equinix-metal.md) (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**
## Quick Start
To deploy the cluster you can use :
### Ansible
#### Usage
Install Ansible according to [Ansible installation guide](/docs/ansible.md#installing-ansible)
then run the following steps:
```ShellSession
# 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.
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
git checkout v2.20.0
docker pull quay.io/kubespray/kubespray:v2.20.0
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:v2.20.0 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
```
### 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 Ansible according to [Ansible installation guide](/docs/ansible.md#installing-ansible)
then run the following step:
```ShellSession
vagrant up
```

## Container Runtime Notes
- 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)
## Requirements
- **Minimum required version of Kubernetes is v1.23**
- **Ansible v2.11+, 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](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.
- 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.
- [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).
## Ingress Plugins
- [nginx](https://kubernetes.github.io/ingress-nginx): the NGINX Ingress Controller.
- [metallb](docs/metallb.md): the MetalLB bare-metal service LoadBalancer provider.

# 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. Please see [a good sample issue](https://github.com/kubernetes-sigs/kubespray/issues/8325)
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/website/blob/main/content/en/releases/patch-releases.md) of kubernetes from `*_checksums` variables.
5. Create the release note with [Kubernetes Release Notes Generator](https://github.com/kubernetes/release/blob/master/cmd/release-notes/README.md). See the following `Release note creation` section for the details.
6. 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
7. An approver creates a release branch in the form `release-X.Y`
8. 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) container images are built and tagged. See the following `Container image creation` section for the details.
9. The `KUBESPRAY_VERSION` variable is updated in `.gitlab-ci.yml`
10. The release issue is closed
11. An announcement email is sent to `dev@kubernetes.io` with the subject `[ANNOUNCE] Kubespray $VERSION is released`
12. 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.
## 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.

# 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!
## Installing Ansible and the dependencies
Install Ansible according to [Ansible installation guide](/docs/ansible.md#installing-ansible)
## 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
```shell
# 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.
```shell
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.
```shell
$EDITOR contrib/dind/kubespray-dind.yaml
```
3. Prepare the inventory and run the playbook
```shell
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`:
```shell
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:
```shell
# 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`.

# Deploying a Kubespray Kubernetes Cluster with GlusterFS
You can either deploy using Ansible on its own by supplying your own inventory file or by using Terraform to create the VMs and then providing a dynamic inventory to Ansible. The following two sections are self-contained, you don't need to go through one to use the other. So, if you want to provision with Terraform, you can skip the **Using an Ansible inventory** section, and if you want to provision with a pre-built ansible inventory, you can neglect the **Using Terraform and Ansible** section.
## Using an Ansible inventory
In the same directory of this ReadMe file you should find a file named `inventory.example` which contains an example setup. Please note that, additionally to the Kubernetes nodes/masters, we define a set of machines for GlusterFS and we add them to the group `[gfs-cluster]`, which in turn is added to the larger `[network-storage]` group as a child group.
Change that file to reflect your local setup (adding more machines or removing them and setting the adequate ip numbers), and save it to `inventory/sample/k8s_gfs_inventory`. Make sure that the settings on `inventory/sample/group_vars/all.yml` make sense with your deployment. Then execute change to the kubespray root folder, and execute (supposing that the machines are all using ubuntu):
```shell
ansible-playbook -b --become-user=root -i inventory/sample/k8s_gfs_inventory --user=ubuntu ./cluster.yml
```
This will provision your Kubernetes cluster. Then, to provision and configure the GlusterFS cluster, from the same directory execute:
```shell
ansible-playbook -b --become-user=root -i inventory/sample/k8s_gfs_inventory --user=ubuntu ./contrib/network-storage/glusterfs/glusterfs.yml
```
If your machines are not using Ubuntu, you need to change the `--user=ubuntu` to the correct user. Alternatively, if your Kubernetes machines are using one OS and your GlusterFS a different one, you can instead specify the `ansible_ssh_user=<correct-user>` variable in the inventory file that you just created, for each machine/VM:
```shell
k8s-master-1 ansible_ssh_host=192.168.0.147 ip=192.168.0.147 ansible_ssh_user=core
k8s-master-node-1 ansible_ssh_host=192.168.0.148 ip=192.168.0.148 ansible_ssh_user=core
k8s-master-node-2 ansible_ssh_host=192.168.0.146 ip=192.168.0.146 ansible_ssh_user=core
```
## Using Terraform and Ansible
First step is to fill in a `my-kubespray-gluster-cluster.tfvars` file with the specification desired for your cluster. An example with all required variables would look like:
```ini
cluster_name = "cluster1"
number_of_k8s_masters = "1"
number_of_k8s_masters_no_floating_ip = "2"
number_of_k8s_nodes_no_floating_ip = "0"
number_of_k8s_nodes = "0"
public_key_path = "~/.ssh/my-desired-key.pub"
image = "Ubuntu 16.04"
ssh_user = "ubuntu"
flavor_k8s_node = "node-flavor-id-in-your-openstack"
flavor_k8s_master = "master-flavor-id-in-your-openstack"
network_name = "k8s-network"
floatingip_pool = "net_external"
# GlusterFS variables
flavor_gfs_node = "gluster-flavor-id-in-your-openstack"
image_gfs = "Ubuntu 16.04"
number_of_gfs_nodes_no_floating_ip = "3"
gfs_volume_size_in_gb = "50"
ssh_user_gfs = "ubuntu"
```
As explained in the general terraform/openstack guide, you need to source your OpenStack credentials file, add your ssh-key to the ssh-agent and setup environment variables for terraform:
```shell
$ source ~/.stackrc
$ eval $(ssh-agent -s)
$ ssh-add ~/.ssh/my-desired-key
$ echo Setting up Terraform creds && \
export TF_VAR_username=${OS_USERNAME} && \
export TF_VAR_password=${OS_PASSWORD} && \
export TF_VAR_tenant=${OS_TENANT_NAME} && \
export TF_VAR_auth_url=${OS_AUTH_URL}
```
Then, standing on the kubespray directory (root base of the Git checkout), issue the following terraform command to create the VMs for the cluster:
```shell
terraform apply -state=contrib/terraform/openstack/terraform.tfstate -var-file=my-kubespray-gluster-cluster.tfvars contrib/terraform/openstack
```
This will create both your Kubernetes and Gluster VMs. Make sure that the ansible file `contrib/terraform/openstack/group_vars/all.yml` includes any ansible variable that you want to setup (like, for instance, the type of machine for bootstrapping).
Then, provision your Kubernetes (kubespray) cluster with the following ansible call:
```shell
ansible-playbook -b --become-user=root -i contrib/terraform/openstack/hosts ./cluster.yml
```
Finally, provision the glusterfs nodes and add the Persistent Volume setup for GlusterFS in Kubernetes through the following ansible call:
```shell
ansible-playbook -b --become-user=root -i contrib/terraform/openstack/hosts ./contrib/network-storage/glusterfs/glusterfs.yml
```
If you need to destroy the cluster, you can run:
```shell
terraform destroy -state=contrib/terraform/openstack/terraform.tfstate -var-file=my-kubespray-gluster-cluster.tfvars contrib/terraform/openstack
```

# Ansible Role: GlusterFS
[![Build Status](https://travis-ci.org/geerlingguy/ansible-role-glusterfs.svg?branch=master)](https://travis-ci.org/geerlingguy/ansible-role-glusterfs)
Installs and configures GlusterFS on Linux.
## Requirements
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.
## Role Variables
Available variables are listed below, along with default values (see `defaults/main.yml`):
```yaml
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).
```yaml
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.
## Dependencies
None.
## Example Playbook
```yaml
- hosts: server
roles:
- geerlingguy.glusterfs
```
