A custom resource framework for AWS CloudFormation
Clone the repo and run the setup.py file in the root:
python setup.py install
You can also use the file to build an RPM:
python setup.py bdist_rpm
As well as python, the resulting RPM will also depend on python-argparse, python-botocore and python-daemon, packaged as RPMs.
The options for the cfn-resource-bridge script are shown below. The CONFIG_PATH needs to contain a file named cfn-resource-bridge.conf with the details of the incoming custom resources and commands to run.
usage: cfn-resource-bridge [-h] [-c CONFIG_PATH] [--no-daemon] [-v]
[-t THREADS]
optional arguments:
-h, --help show this help message and exit
-c CONFIG_PATH, --config CONFIG_PATH
The configuration directory (default: /etc/cfn)
--no-daemon Do not daemonize
-v, --verbose Enables verbose logging
-t THREADS, --threads THREADS
Configure the number of threads to use
Example config file:
[eip-lookup]
resource_type=Custom::EipLookup
queue_url=https://your-sqs-queue-url-that-is-subscribed-to-the-sns-topic-in-the-service-token
timeout=60
default_action=/home/ec2-user/lookup-eip.py
The config file cfn-resource-bridge.conf can contain multiple sections and each section can contain the following options:
queue_url- the URL of the queue to pull messages from.default_action- the default action to perform when a message is received.create_action- the action to perform when aCreatemessage is received.delete_action- the action to perform when aDeletemessage is received.update_action- the action to perform when aUpdatemessage is received.timeout- the default timeout for messages taken from the queue.create_timeout- the message timeout for create actions.delete_timeout- the message timeout for delete actions.update_timeout- the message timeout for update actions.flatten- flatten resource properties in environment variables (true by default).service_token- optional service token for the event.resource_type- the custom resource type.region- the AWS region - only required if it can't be determined from the queue URL.
