This is a fork of Will Thames [ansible-review](https://github.com/willthames/ansible-review) so credits goes to him
|
|
for his work on ansible-review and ansible-lint.
|
|
|
|
`ansible-later` is a best pratice scanner and linting tool. In most cases, if you write ansibel roles in a team,
|
|
it helps to have a coding or best practice guideline in place. This will make ansible roles more readable for all
|
|
maintainers and can reduce the troubleshooting time.
|
|
|
|
`ansible-later` does _**not**_ ensure that your role will work as expected. For Deployment test you can use other tools
|
|
like [molecule](https://github.com/ansible/molecule).
|
|
|
|
The project name is an acronym for **L**ovely **A**utomation **TE**sting f**R**mework.

|
### Setup
|
|
|
|
#### Using pip
|
|
|
|
```Shell
|
|
# From internal pip repo as user
|
|
pip install ansible-later --user
|
|
|
|
# .. or as root
|
|
sudo pip install ansible-later
|
|
```
|
|
|
|
#### From source
|
|
|
|
```Shell
|
|
# Install dependency
|
|
git clone https://github.com/xoxys/ansible-later
|
|
export PYTHONPATH=$PYTHONPATH:`pwd`/ansible-later/ansiblelater
|
|
export PATH=$PATH:`pwd`/ansible-later/bin
|
|
```
|
|
|
|
### Configuration
|
|
|
|
ansible-later comes with some default settigs which should be sufficent for most users to start,
|
|
but you can adjust most settings to your needs.
|
|
|
|
Changes can be made in a yaml configuration file or through cli options
|
|
which will be processed in the following order (last wins):
|
|
|
|
- default config (build-in)
|
|
- global config file (this will depend on your operating system)
|
|
- folderbased config file (`.later.yml` file in current working folder)
|
|
- cli options
|
|
|
|
Be careful! YAML Attributes will be overwritten while lists in any
|
|
config file will be merged.
|
|
|
|
To make it easier to review a singel file e.g. for debugging purpose, amsible-later
|
|
will ignore `exclude_files` and `ignore_dotfiles` options.
|
|
|
|
#### Default settings
|
|
|
|
```YAML

```
|
|
|
|
### Usage
|
|
|
|
```Shell
|
|
ansible-later FILES
|
|
```
|
|
|
|
If you don't pass any file to ansible-later it will review all files including subdirs in
|
|
the current working directory (hidden files and folders are excluded by default).
|
|
|
|
Otherwise you can pass a space delimited list of files to review. You can also pass glob
|
|
patterns to ansible-later:
|
|
|
|
```Shell
|
|
# Review single files
|
|
ansible-later meta/main.yml tasks/install.yml
|
|
|
|
# Review all yml files (including subfolders)
|
|
ansible-later **/*.yml
|
|
```
|
|
|
|
ansible-later will review inventory files, role files, python code (modules, plugins)
|
|
and playbooks.
|
|
|
|
- The goal is that each file that changes in a
|
|
changeset should be reviewable simply by passing
|
|
those files as the arguments to ansible-later.
|
|
- Using `{{ playbook_dir }}` in sub roles is so far
|
|
very hard.
|
|
- This should work against various repository styles
|
|
- per-role repository
|
|
- roles with sub-roles
|
|
- per-playbook repository
|
|
- It should work with roles requirement files and with local roles
|
|
|
|
### Buildin rules
|
|
|
|
Reviews are nothing without some rules or standards against which to review. ansible-later
|
|
comes with a couple of built-in checks explained in the following table.
|
|
|
|
| Rule | ID | Description | Parameter |
|
|

|
|
|
|
### Build your own rules
|
|
|
|
#### The standards file
|
|
|
|
A standards file comprises a list of standards, and optionally some methods to
|
|
check those standards.
|
|
|
|
Create a file called standards.py (this can import other modules)
|
|
|
|
```Python
|
|
from ansiblelater include Standard, Result
|
|
|
|
tasks_are_uniquely_named = Standard(dict(
|
|
# ID's are optional but if you use ID's they have to be unique
|
|
id="ANSIBLE0003",
|
|
# Short description of the standard goal
|
|
name="Tasks and handlers must be uniquely named within a single file",
|
|
check=check_unique_named_task,
|
|
version="0.1",
|
|
types=["playbook", "task", "handler"],
|
|
))
|
|
|
|
standards = [
|
|
tasks_are_uniquely_named,
|
|
role_must_contain_meta_main,
|
|
]
|
|
```
|
|
|
|
When you add new standards, you should increment the version of your standards.
|
|
Your playbooks and roles should declare what version of standards you are
|
|
using, otherwise ansible-later assumes you're using the latest. The declaration
|
|
is done by adding standards version as first line in the file. e.g.
|
|
|
|
```INI
|
|
# Standards: 1.2
|
|
```
|
|
|
|
To add standards that are advisory, don't set the version. These will cause
|
|
a message to be displayed but won't constitute a failure.
|
|
|
|
When a standard version is higher than declared version, a message will be
|
|
displayed 'WARN: Future standard' and won't constitute a failure.
|
|
|
|
An example standards file is available at
|
|
[ansiblelater/examples/standards.py](ansiblelater/examples/standards.py)
|
|
|
|
If you only want to check one or two standards quickly (perhaps you want
|
|
to review your entire code base for deprecated bare words), you can use the
|
|
`-s` flag with the name of your standard. You can pass `-s` multiple times.
|
|
|
|
```Shell
|
|
git ls-files | xargs ansible-later -s "bare words are deprecated for with_items"
|
|
```
|
|
|
|
You can see the name of the standards being checked for each different file by running
|
|
`ansible-later` with the `-v` option.
|
|
|
|
#### Candidates
|
|
|
|
Each file passed to `ansible-later` will be classified. The result is a `Candidate` object
|
|
which contains some meta informations and is an instance of one of following object types.
|
|
|
|
| Object type | Description |
|
|
|-------------|------------------------------------------------------------------------------------------------------------------------------|
|
|
| Task | all files within the parent dir `tasks` |
|
|
| Handler | all files within the parent dir `handler` |
|
|
| RoleVars | all files within the parent dir `vars` or `default` |
|
|
| GroupVars | all files (including subdirs) within the parent dir `group_vars` |
|
|
| HostVars | all files (including subdirs) within the parent dir `host_vars` |
|
|
| Meta | all files within the parent dir `meta` |
|
|
| Code | all files within the parent dir `library`, `lookup_plugins`, `callback_plugins` and `filter_plugins` or python files (`.py`) |
|
|
| Inventory | all files within the parent dir `inventories` and `inventory` or `hosts` as filename |
|
|
| Rolesfile | all files with `rolesfile` or `requirements` in filename |
|
|
| Makefile | all files with `Makefile` in filename |
|
|
| Template | all files (including subdirs) within the parent dir `templates` or jinja2 files (`.j2`) |
|
|
| File | all files (including subdirs) within the parent dir `files` |
|
|
| Playbook | all yaml files (`.yml` or `.yaml`) not maching a previous object type |
|
|
| Doc | all files with `README` in filename |
|
|
|
|
#### Minimal standards checks
|
|
|
|
A typical standards check will look like:
|
|
|
|
```Python
|
|
def check_playbook_for_something(candidate, settings):
|
|
result = Result(candidate.path) # empty result is a success with no output
|
|
with open(candidate.path, 'r') as f:
|
|
for (lineno, line) in enumerate(f):
|
|
if line is dodgy:
|
|
# enumerate is 0-based so add 1 to lineno
|
|
result.errors.append(Error(lineno+1, "Line is dodgy: reasons"))
|
|
return result
|
|
```
|
|
|
|
All standards check take a candidate object, which has a path attribute.
|
|
The type can be inferred from the class name (i.e. `type(candidate).__name__`)
|
|
or from the table [here](#candidates).
|
|
|
|
They return a `Result` object, which contains a possibly empty list of `Error`
|
|
objects. `Error` objects are formed of a line number and a message. If the
|
|
error applies to the whole file being reviewed, set the line number to `None`.
|
|
Line numbers are important as `ansible-later` can review just ranges of files
|
|
to only review changes (e.g. through piping the output of `git diff` to
|
|
`ansible-later`).
