awacs 2.4.1

Description:

awacs 2.4.1

About
awacs - Amazon Web Access Control Subsystem
The awacs library allows for easier creation of AWS Access Policy
Language JSON by writing Python code to describe the AWS policies.
To facilitate catching policy format or JSON errors early the
library has property and type checking built into the classes.
NOTE: The old awacs.aws.Policy object is going to be deprecated in the
future, in preference for the awacs.aws.PolicyDocument class. This is due
to confusion that arises between the old object and troposphere.iam.Policy
objects.


Installation
awacs can be installed using the pip distribution system for python by
issuing:
$ pip install awacs
Alternatively, you can run use setup.py to install by cloning this repository
and issuing:
$ python setup.py install


Examples
An example to use this comes from the AWS IAM documentation.
This shows creating policy attached to an Amazon S3 bucket:
from awacs.aws import Action, Allow, PolicyDocument, Principal, Statement
from awacs.iam import ARN as IAM_ARN
from awacs.s3 import ARN as S3_ARN

account = "123456789012"
user = "user/Bob"

pd = PolicyDocument(
Version="2012-10-17",
Id="S3-Account-Permissions",
Statement=[
Statement(
Sid="1",
Effect=Allow,
Principal=Principal("AWS", [IAM_ARN(user, '', account)]),
Action=[Action("s3", "*")],
Resource=[S3_ARN("my_corporate_bucket/*"),],
),
],
)
print(pd.to_json())
would produce this json policy:
{
"Id": "S3-Account-Permissions",
"Statement": [
{
"Action": [
"s3:*"
],
"Effect": "Allow",
"Principal": [
{
"AWS": [
"arn:aws:iam::123456789012:user/Bob"
]
}
],
"Resource": [
"arn:aws:s3:::my_corporate_bucket/*"
],
"Sid": "1"
}
],
"Version": "2012-10-17"
}

Contributing new actions
To update actions there is a generator tool which will scrape policies from
AWS’s documentation resource and auto-generate new files.
The following commands can be run (with Python 3.7+) to update the repo:
$ python3 -m pip install -r scrape/requirements.txt
$ python3 -m pip install .
$ python3 ./scrape/scrape.py
$ git diff
