### Status
[![Build Status](https://travis-ci.org/beelit94/python-terraform.svg?branch=develop)](https://travis-ci.org/beelit94/python-terraform)

## Installation
2016-11-19 17:11:21 +00:00
pip install python-terraform
## Implementation
IMHO, how terraform design boolean options is confusing.
Take `input=True` and `-no-color` option of `apply` command for example,
they're all boolean value but with different option type.
This make api caller don't have a general rule to follow but to do
a exhaustive method implementation which I don't prefer to.
Therefore I end-up with using `IsFlagged` or `IsNotFlagged` as value of option
like `-no-color` and `True/False` value reserved for option like
## Usage
For any terraform command
from python_terraform import Terraform
t = Terraform()
return_code, stdout, stderr = t.<cmd_name>(*arguments, **options)
For any options
if there's a dash in the option name, use under line instead of dash,
ex. -no-color --> no_color
if it's a simple flag with no value, value should be IsFlagged
ex. cmd('taint', allow_missing=IsFlagged)
if it's a boolean value flag like "-refresh=true", assign True or False
if it's a flag could be used multiple times, assign list to it's value
if it's a "var" variable flag, assign dictionary to it
if a value is None, will skip this option
## Examples
### Have a test.tf file under folder "/home/test"
#### 1. apply with variables a=b, c=d, refresh=false, no color in the output
In shell:
cd /home/test
terraform apply -var='a=b' -var='c=d' -refresh=false -no-color
In python-terraform:
from python_terraform import Terraform
tf = Terraform(working_dir='/home/test')
tf.apply(no_color=IsFlagged, refresh=False, var={'a':'b', 'c':'d'})
or
from python_terraform import Terraform
tf = Terraform()
tf.apply('/home/test', no_color=IsFlagged, refresh=False, var={'a':'b', 'c':'d'})
#### 2. fmt command, diff=true
In shell:
cd /home/test
terraform fmt -diff=true
In python-terraform:
from python_terraform import Terraform
tf = terraform(working_dir='/home/test')
tf.fmt(diff=True)
