A [Hetzner Cloud](https://www.hetzner.com/cloud) plugin for [Molecule](https://molecule.readthedocs.io/en/latest/).

This plugin allows you to do `molecule init role myrolename -d hetznercloud`
and have Molecule provision on-demand Hetzner Cloud VPSes of your choice for
your integration testing. New VPSes will be automagically created and
provisioned on each `molecule test` run, SSH keys are generated and managed
internally and all resources are cleaned regardless whether the role under test
succeeds or fails.

## Support

If you use this plugin and find it useful, please consider supporting my
maintenance work financially through [Liberapay](https://liberapay.com/decentral1se/) or my
[Github Sponsor profile](https://github.com/sponsors/decentral1se). I do not receive any
financial support from RedHat or Hetzner Cloud for this work.

## Usage

You need to expose a `HCLOUD_TOKEN` environment variable in your environment.
Find out more about how to get one of those [over here](https://docs.hetzner.cloud/#overview-authentication)

```bash
$ export HCLOUD_TOKEN=mycoolapitoken
```

Then install the required Python package.

```bash
$ pip install molecule-hetznercloud
$ molecule init role myrolename -d hetznercloud
```

Your `myrolename/molecule/default/molecule.yml` should then look like the following.

```yaml
---
dependency:
  name: galaxy
driver:
  name: hetznercloud
platforms:
  - name: my-instance-name
    server_type: cx11
    image: debian-10
provisioner:
  name: ansible
verifier:
  name: ansible
```

Please see [docs.hetzner.cloud](https://docs.hetzner.cloud/) for information regarding images and server types.

Then just run the role.

```bash
$ cd myrolename && molecule test
```

To ease initial debugging for getting thing started, also expose the following
environment variables.

```bash
$ export MOLECULE_NO_LOG=False  # not so verbose, helpful
$ export MOLECULE_DEBUG=True  # very verbose, last ditch effort
```
