|
||||

||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must

|
||||
within such NOTICE file, excluding those notices that do not

|
||||

|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||

|
||||

|
||||
other commercial damages or losses), even if such Contributor
|
||||

|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability

# Autoomated build of HA k3s Cluster with `kube-vip` and MetalLB
|
||||
|
||||
|
||||
|
||||
This playbook will build an HA Kubernetes cluster with `k3s`, `kube-vip` and MetalLB via `ansible`.
|
||||
|
||||
This is based on the work from [this fork](https://github.com/212850a/k3s-ansible) which is based on the work from [k3s-io/k3s-ansible](https://github.com/k3s-io/k3s-ansible). It uses [kube-vip](https://kube-vip.io/) to create a load balancer for control plane, and [metal-lb](https://metallb.universe.tf/installation/) for its service `LoadBalancer`.
|
||||
|
||||
If you want more context on how this works, see:
|
||||
|
||||
📄 [Documentation](https://technotim.live/posts/k3s-etcd-ansible/) (including example commands)
|
||||
|
||||
📺 [Watch the Video](https://www.youtube.com/watch?v=CbkEWcUZ7zM)
|
||||
|
||||
## 📖 k3s Ansible Playbook
|
||||
|
||||
Build a Kubernetes cluster using Ansible with k3s. The goal is easily install a HA Kubernetes cluster on machines running:
|
||||
|
||||
- [x] Debian (tested on version 11)
|
||||
- [x] Ubuntu (tested on version 22.04)
|
||||
- [x] Rocky (tested on version 9)
|
||||
|
||||
on processor architecture:
|
||||
|
||||
- [X] x64
|
||||
- [X] arm64
|
||||
- [X] armhf
|
||||
|
||||
## ✅ System requirements
|
||||
|
||||
- Control Node (the machine you are running `ansible` commands) must have Ansible 2.11+ If you need a quick primer on Ansible [you can check out my docs and setting up Ansible](https://technotim.live/posts/ansible-automation/).
|
||||
|
||||
- You will also need to install collections that this playbook uses by running `ansible-galaxy collection install -r ./collections/requirements.yml` (important❗)
|
||||
|
||||
- [`netaddr` package](https://pypi.org/project/netaddr/) must be available to Ansible. If you have installed Ansible via apt, this is already taken care of. If you have installed Ansible via `pip`, make sure to install `netaddr` into the respective virtual environment.
|
||||
|
||||
- `server` and `agent` nodes should have passwordless SSH access, if not you can supply arguments to provide credentials `--ask-pass --ask-become-pass` to each command.
|
||||
|
||||
## 🚀 Getting Started
|
||||
|
||||
### 🍴 Preparation
|
||||
|
||||
First create a new directory based on the `sample` directory within the `inventory` directory:
|
||||
|
||||
```bash
|
||||
cp -R inventory/sample inventory/my-cluster
|
||||
```
|
||||
|
||||
Second, edit `inventory/my-cluster/hosts.ini` to match the system information gathered above
|
||||
|
||||
For example:
|
||||
|
||||
```ini
|
||||
[master]
|
||||
192.168.30.38
|
||||
192.168.30.39
|
||||
192.168.30.40
|
||||
|
||||
[node]
|
||||
192.168.30.41
|
||||
192.168.30.42
|
||||
|
||||
[k3s_cluster:children]
|
||||
master
|
||||
node
|
||||
```
|
||||
|
||||
If multiple hosts are in the master group, the playbook will automatically set up k3s in [HA mode with etcd](https://rancher.com/docs/k3s/latest/en/installation/ha-embedded/).
|
||||
|
||||
Finally, copy `ansible.example.cfg` to `ansible.cfg` and adapt the inventory path to match the files that you just created.
|
||||
|
||||
This requires at least k3s version `1.19.1` however the version is configurable by using the `k3s_version` variable.
|
||||
|
||||
If needed, you can also edit `inventory/my-cluster/group_vars/all.yml` to match your environment.
|
||||
|
||||
### ☸️ Create Cluster
|
||||
|
||||
Start provisioning of the cluster using the following command:
|
||||
|
||||
```bash
|
||||
ansible-playbook site.yml -i inventory/my-cluster/hosts.ini
|
||||
```
|
||||
|
||||
After deployment control plane will be accessible via virtual ip-address which is defined in inventory/group_vars/all.yml as `apiserver_endpoint`
|
||||
|
||||
### 🔥 Remove k3s cluster
|
||||
|
||||
```bash
|
||||
ansible-playbook reset.yml -i inventory/my-cluster/hosts.ini
|
||||
```
|
||||
|
||||
>You should also reboot these nodes due to the VIP not being destroyed
|
||||
|
||||
## ⚙️ Kube Config
|
||||
|
||||
To copy your `kube config` locally so that you can access your **Kubernetes** cluster run:
|
||||
|
||||
```bash
|
||||
scp debian@master_ip:/etc/rancher/k3s/k3s.yaml ~/.kube/config
|
||||
```
|
||||
If you get file Permission denied, go into the node and temporarly run:
|
||||
```bash
|
||||
sudo chmod 777 /etc/rancher/k3s/k3s.yaml
|
||||
```
|
||||
Then copy with the scp command and reset the permissions back to:
|
||||
```bash
|
||||
sudo chmod 600 /etc/rancher/k3s/k3s.yaml
|
||||
```
|
||||
|
||||
You'll then want to modify the config to point to master IP by running:
|
||||
```bash
|
||||
sudo nano ~/.kube/config
|
||||
```
|
||||
Then change `server: https://127.0.0.1:6443` to match your master IP: `server: https://192.168.1.222:6443`
|
||||
|
||||
### 🔨 Testing your cluster

### Troubleshooting
|
||||
|
||||
Be sure to see [this post](https://github.com/techno-tim/k3s-ansible/discussions/20) on how to troubleshoot common problems
|
||||
|
||||
### Testing the playbook using molecule
|
||||
|
||||
This playbook includes a [molecule](https://molecule.rtfd.io/)-based test setup.
|
||||
It is run automatically in CI, but you can also run the tests locally.
|
||||
This might be helpful for quick feedback in a few cases.
|
||||
You can find more information about it [here](molecule/README.md).
|
||||
|
||||
### Pre-commit Hooks
|
||||
|
||||
This repo uses `pre-commit` and `pre-commit-hooks` to lint and fix common style and syntax errors. Be sure to install python packages and then run `pre-commit install`. For more information, see [pre-commit](https://pre-commit.com/)

## 🌌 Ansible Galaxy
|
||||
|
||||
This collection can now be used in larger ansible projects.
|
||||
|
||||
Instructions:
|
||||
|
||||
- create or modify a file `collections/requirements.yml` in your project
|
||||
|
||||
```yml
|
||||
collections:
|
||||
- name: ansible.utils
|
||||
- name: community.general
|
||||
- name: ansible.posix
|
||||
- name: kubernetes.core
|
||||
- name: https://github.com/techno-tim/k3s-ansible.git
|
||||
type: git
|
||||
version: master
|
||||
```
|
||||
|
||||
- install via `ansible-galaxy collection install -r ./collections/requirements.yml`
|
||||
- every role is now available via the prefix `techno_tim.k3s_ansible.` e.g. `techno_tim.k3s_ansible.lxc`
|
||||

# Test suites for `k3s-ansible`
|
||||
|
||||
This folder contains the [molecule](https://molecule.rtfd.io/)-based test setup for this playbook.
|
||||
|
||||
## Scenarios
|
||||
|
||||
We have these scenarios:
|
||||
|
||||
- **default**:
|
||||
A 3 control + 2 worker node cluster based very closely on the [sample inventory](../inventory/sample/).
|
||||
- **ipv6**:
|
||||
A cluster that is externally accessible via IPv6 ([more information](ipv6/README.md))
|
||||
To save a bit of test time, this cluster is _not_ highly available, it consists of only one control and one worker node.
|
||||
- **single_node**:
|
||||
Very similar to the default scenario, but uses only a single node for all cluster functionality.
|
||||
- **calico**:
|
||||
The same as single node, but uses calico cni instead of flannel.
|
||||
- **cilium**:
|
||||
The same as single node, but uses cilium cni instead of flannel.
|
||||
- **kube-vip**
|
||||
The same as single node, but uses kube-vip as service loadbalancer instead of MetalLB
|
||||
|
||||
## How to execute
|
||||
|
||||
To test on your local machine, follow these steps:
|
||||
|
||||
### System requirements
|
||||
|
||||
Make sure that the following software packages are available on your system:
|
||||
|
||||
- [Python 3](https://www.python.org/downloads)
|
||||
- [Vagrant](https://www.vagrantup.com/downloads)
|
||||
- [VirtualBox](https://www.virtualbox.org/wiki/Downloads)
|
||||
|
||||
### Set up VirtualBox networking on Linux and macOS
|
||||
|
||||
_You can safely skip this if you are working on Windows._
|
||||
|
||||
Furthermore, the test cluster uses the `192.168.30.0/24` subnet which is [not set up by VirtualBox automatically](https://www.virtualbox.org/manual/ch06.html#network_hostonly).
|
||||
To set the subnet up for use with VirtualBox, please make sure that `/etc/vbox/networks.conf` exists and that it contains this line:
|
||||
|
||||
```
|
||||
* 192.168.30.0/24
|
||||
* fdad:bad:ba55::/64
|
||||
```
|
||||
|
||||
### Install Python dependencies
|
||||
|
||||
You will get [Molecule, Ansible and a few extra dependencies](../requirements.txt) via [pip](https://pip.pypa.io/).
|
||||
Usually, it is advisable to work in a [virtual environment](https://docs.python.org/3/tutorial/venv.html) for this:
|
||||
|
||||
```bash
|
||||
cd /path/to/k3s-ansible
|
||||
|
||||
# Create a virtualenv at ".env". You only need to do this once.
|
||||
python3 -m venv .env
|
||||
|
||||
# Activate the virtualenv for your current shell session.
|
||||
# If you start a new session, you will have to repeat this.
|
||||
source .env/bin/activate
|
||||
|
||||
# Install the required packages into the virtualenv.
|
||||
# These remain installed across shell sessions.
|
||||
python3 -m pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### Run molecule
|
||||
|
||||
With the virtual environment from the previous step active in your shell session, you can now use molecule to test the playbook.
|
||||
Interesting commands are:
|
||||
|
||||
- `molecule create`: Create virtual machines for the test cluster nodes.
|
||||
- `molecule destroy`: Delete the virtual machines for the test cluster nodes.
|
||||
- `molecule converge`: Run the `site` playbook on the nodes of the test cluster.
|
||||
- `molecule side_effect`: Run the `reset` playbook on the nodes of the test cluster.
|
||||
- `molecule verify`: Verify that the cluster works correctly.
|
||||
- `molecule test`: The "all-in-one" sequence of steps that is executed in CI.
|
||||
This includes the `create`, `converge`, `verify`, `side_effect` and `destroy` steps.
|
||||
See [`molecule.yml`](default/molecule.yml) for more details.

# Sample IPv6 configuration for `k3s-ansible`
|
||||
|
||||
This scenario contains a cluster configuration which is _IPv6 first_, but still supports dual-stack networking with IPv4 for most things.
|
||||
This means:
|
||||
|
||||
- The API server VIP is an IPv6 address.
|
||||
- The MetalLB pool consists of both IPv4 and IPv4 addresses.
|
||||
- Nodes as well as cluster-internal resources (pods and services) are accessible via IPv4 as well as IPv6.
|
||||
|
||||
## Network design
|
||||
|
||||
All IPv6 addresses used in this scenario share a single `/48` prefix: `fdad:bad:ba55`.
|
||||
The following subnets are used:
|
||||
|
||||
- `fdad:bad:ba55:`**`0`**`::/64` is the subnet which contains the cluster components meant for external access.
|
||||
That includes:
|
||||
|
||||
- The VIP for the Kubernetes API server: `fdad:bad:ba55::333`
|
||||
- Services load-balanced by MetalLB: `fdad:bad:ba55::1b:0/112`
|
||||
- Cluster nodes: `fdad:bad:ba55::de:0/112`
|
||||
- The host executing Vagrant: `fdad:bad:ba55::1`
|
||||
|
||||
In a home lab setup, this might be your LAN.
|
||||
|
||||
- `fdad:bad:ba55:`**`4200`**`::/56` is used internally by the cluster for pods.
|
||||
|
||||
- `fdad:bad:ba55:`**`4300`**`::/108` is used internally by the cluster for services.
|
||||
|
||||
IPv4 networking is also available:
|
||||
|
||||
- The nodes have addresses inside `192.168.123.0/24`.
|
||||
MetalLB also has a bit of address space in this range: `192.168.123.80-192.168.123.90`
|
||||
- For pods and services, the k3s defaults (`10.42.0.0/16` and `10.43.0.0/16)` are used.
|
||||
|
||||
Note that the host running Vagrant is not part any of these IPv4 networks.
