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

## Installation
    pip install python-terraform

## Usage
For any terraform command

    def cmd(self, cmd, *args, **kwargs):
        """
        run a terraform command, if success, will try to read state file
        :param cmd: command and sub-command of terraform, seperated with space
                    refer to https://www.terraform.io/docs/commands/index.html
        :param args: arguments of a command
        :param kwargs:  any option flag with key value without prefixed dash character
                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, 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
        :return: ret_code, out, err


## Examples
### Have a test.tf file under folder "/home/test"
#### 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'})
#### taint command, allow-missing and no color
In shell:

    cd /home/test
    terraform taint -allow-missing -no-color
    
In python-terraform:
    
    from python_terraform import Terraform
    tf = terraform(working_dir='/home/test')
    tf.cmd('taint', allow_missing=IsFlagged, no_color=IsFlagged)
