### 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).

# 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.
|
||||
|
||||
## 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.
