* Tidy up and refactoring of tasks
- `k3s_config_dir` derived from `k3s_config_file`, reused throughout the role
to allow for easy removal of "Rancher" references #73.
- `k3s_token_location` has moved to be in `k3s_config_dir`.
- Tasks for creating directories now looped to caputure configuration from
`k3s_server` and `k3s_agent` and ensure directories exist before k3s
starts, see #75.
- Server token collected directly from token file, not symlinked file
(node-token).
- `k3s_runtime_config` defined in `vars/` for validation and overwritten in
tasks for control plane and workers.
- Removed unused references to GitHub API.
* set_fact now uses FQCN
* re-pin molecule<3.2
* Command module now uses FQCN
* Added package checks for #72
* Reorder task files
- Docker tasks moved into a separate directory for ease of removal #67
- Bugfix: Control plane on alternate port didn't work.
- Validation tasks grouped
* Fix Fedora tests
* Add optional documentation links to validations steps #76
* Removed jmespath requirement
* Fix issue with data collection
* Release candidate
- Added option to skip validation checks #47
- Add SELinux support in containerd #48
- Added check for Etcd member count #46
- Moved token to a file #50
- Added Etcd snapshot configuration options #49
I was receiving this error when running the task on my [Odroid HC1 running Armbian](https://www.armbian.com/odroid-hc1/):
```
TASK [xanmanning.k3s : Ensure target host architecture information is set as a fact] **************************************************************************
fatal: [odroid]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'armv7l'\n\nThe error appears to have been in '/home/jdmarble/.ansible/roles/xanmanning.k3s/tasks/download-k3s.yml': line 3, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Ensure target host architecture information is set as a fact\n ^ here\n"}
```
I worked around the problem by overriding `k3s_arch_lookup` in my play book:
```yaml
---
- hosts: all
roles:
- role: xanmanning.k3s
k3s_arch_lookup:
armv7l:
arch: arm
suffix: "-armhf"
```
