# Shlax: Pythonic automation tool
|
||||
|
||||
Shlax is a Python framework for system automation, initially with the purpose
|
||||
of replacing docker, docker-compose and ansible with a single tool, with the
|
||||
purpose of code-reuse. It may be viewed as "async fabric rewrite by a
|
||||
megalomanic Django fanboy".
|
||||
|
||||
The pattern resolves around two moving parts: Actions and Targets.
|
||||
|
||||
## Action
|
||||
|
||||
An action is a function that takes a target argument, it may execute nested
|
||||
actions by passing over the target argument which collects the results.
|
||||
|
||||
Example:
|
||||
|
||||
```python
|
||||
async def hello_world(target):
|
||||
"""Bunch of silly commands to demonstrate action programming."""
|
||||
await target.mkdir('foo')
|
||||
python = await target.which('python3', 'python')
|
||||
await target.exec(f'{python} --version > foo/test')
|
||||
version = target.exec('cat foo/test').output
|
||||
print('version')
|
||||
```
|
||||
|
||||
### Recursion
|
||||
|
||||
An action may call other actions recursively. There are two ways:
|
||||
|
||||
```python
|
||||
async def something(target):
|
||||
# just run the other action code
|
||||
hello_world(target)
|
||||
|
||||
# or delegate the call to target
|
||||
target(hello_world)
|
||||
```
|
||||
|
||||
In the first case, the resulting count of ran actions will remain 1:
|
||||
"something" action.
|
||||
|
||||
In the second case, the resulting count of ran actions will be 2: "something"
|
||||
and "hello_world".
|
||||
|
||||
### Callable classes
|
||||
|
||||
Actually in practice, Actions are basic callable Python classes, here's a basic
|
||||
example to run a command:
|
||||
|
||||
```python
|
||||
class Run:
|
||||
def __init__(self, cmd):
|
||||
self.cmd = cmd
|
||||
|
||||
async def __call__(self, target):
|
||||
return await target.exec(self.cmd)
|
||||
```
|
||||
|
||||
This allows to create callable objects which may be called just like functions
|
||||
and as such be appropriate actions, instead of:
|
||||
|
||||
```python
|
||||
async def one(target):
|
||||
target.exec('one')
|
||||
|
||||
async def two(target):
|
||||
target.exec('two')
|
||||
```
|
||||
|
||||
You can do:
|
||||
|
||||
```python
|
||||
one = Run('one')
|
||||
two = Run('two')
|
||||
```
|
||||
|
||||
### Parallel execution
|
||||
|
||||
Actions may be executed in parallel with an action named ... Parallel. This
|
||||
defines an action that will execute three actions in parallel:
|
||||
|
||||
```python
|
||||
action = Parallel(
|
||||
hello_world,
|
||||
something,
|
||||
Run('echo hi'),
|
||||
)
|
||||
```
|
||||
|
||||
In this case, all actions must succeed for the parallel action to be considered
|
||||
a success.
|
||||
|
||||
### Methods
|
||||
|
||||
An action may also be a method, as long as it just takes a target argument, for
|
||||
example:
|
||||
|
||||
```python
|
||||
class Thing:
|
||||
def start(self, target):
|
||||
"""Starts thing"""
|
||||
|
||||
def stop(self, target):
|
||||
"""Stops thing"""
|
||||
|
||||
action = Thing().start
|
||||
```
|
||||
|
||||
### Cleaning
|
||||
|
||||
If an action defines a `clean` method, it will always be called wether or not
|
||||
the action succeeded. Example:
|
||||
|
||||
```python
|
||||
class Thing:
|
||||
def __call__(self, target):
|
||||
"""Do some thing"""
|
||||
|
||||
def clean(self, target):
|
||||
"""Clean-up target after __call__"""
|
||||
```
|
||||
|
||||
## Target
|
||||
|
||||
A Target is mainly an object providing an abstraction layer over the system we
|
||||
want to automate with actions. It defines functions to execute a command, mount
|
||||
a directory, copy a file, manage environment variables and so on.
|
||||
|
||||
### Pre-configuration
|
||||
|
||||
A Target can be pre-configured with a list of Actions in which case calling the
|
||||
target without argument will execute its Actions until one fails by raising an
|
||||
Exception:
|
||||
|
||||
```python
|
||||
say_hello = Localhost(
|
||||
hello_world,
|
||||
Run('echo hi'),
|
||||
)
|
||||
await say_hello()
|
||||
```
|
||||
|
||||
### Results
|
||||
|
||||
Every time a target execute an action, it will set the "status" attribute on it
|
||||
to "success" or "failure", and add it to the "results" attribute:
|
||||
|
||||
```
|
||||
say_hello = Localhost(Run('echo hi'))
|
||||
await say_hello()
|
||||
say_hello.results # contains the action with status="success"
|
||||
```
