About

troposphere - library to create AWS CloudFormation_ descriptions

The troposphere library allows for easier creation of the AWS CloudFormation JSON_ by writing Python code to describe the AWS resources. troposphere also
includes some basic support for OpenStack resources_ via Heat.

To facilitate catching CloudFormation or JSON errors early the library has
property and type checking built into the classes.

Installation

troposphere can be installed using the pip distribution system for Python by
issuing:

.. code:: sh

$ pip install troposphere

To install troposphere with awacs <https://github.com/cloudtools/awacs>_
(recommended soft dependency):

.. code:: sh

$ pip install troposphere[policy]

Alternatively, you can run use setup.py to install by cloning this repository
and issuing:

.. code:: sh

$ python setup.py install  # you may need sudo depending on your python installation

Examples

A simple example to create an instance would look like this:

.. code:: python

>>> from troposphere import Ref, Template
>>> import troposphere.ec2 as ec2
>>> t = Template()
>>> instance = ec2.Instance("myinstance")
>>> instance.ImageId = "ami-951945d0"
>>> instance.InstanceType = "t1.micro"
>>> t.add_resource(instance)
<troposphere.ec2.Instance object at 0x101bf3390>
>>> print(t.to_json())
{
    "Resources": {
        "myinstance": {
            "Properties": {
                "ImageId": "ami-951945d0",
                "InstanceType": "t1.micro"
            },
            "Type": "AWS::EC2::Instance"
        }
    }
}
>>> print(t.to_yaml())
Resources:
    myinstance:
        Properties:
            ImageId: ami-951945d0
            InstanceType: t1.micro
        Type: AWS::EC2::Instance

Alternatively, parameters can be used instead of properties:

.. code:: python

>>> instance = ec2.Instance("myinstance", ImageId="ami-951945d0", InstanceType="t1.micro")
>>> t.add_resource(instance)
<troposphere.ec2.Instance object at 0x101bf3550>

And add_resource() returns the object to make it easy to use with Ref():

.. code:: python

>>> instance = t.add_resource(ec2.Instance("myinstance", ImageId="ami-951945d0", InstanceType="t1.micro"))
>>> Ref(instance)
<troposphere.Ref object at 0x101bf3490>

Examples of the error checking (full tracebacks removed for clarity):

Incorrect property being set on AWS resource:

.. code:: python

>>> import troposphere.ec2 as ec2
>>> ec2.Instance("ec2instance", image="i-XXXX")
Traceback (most recent call last):
...
AttributeError: AWS::EC2::Instance object does not support attribute image

Incorrect type for AWS resource property:

.. code:: python

>>> ec2.Instance("ec2instance", ImageId=1)
Traceback (most recent call last):
...
TypeError: ImageId is <type 'int'>, expected <type 'basestring'>

Missing required property for the AWS resource:

.. code:: python

>>> from troposphere import Template
>>> import troposphere.ec2 as ec2
>>> t = Template()
>>> t.add_resource(ec2.Instance("ec2instance", InstanceType="m3.medium"))
<troposphere.ec2.Instance object at 0x109ee2e50>
>>> print(t.to_json())
Traceback (most recent call last):
...
ValueError: Resource ImageId required in type AWS::EC2::Instance
