cfn-sphere-python
Wrapper for using cfn-sphere stacks configuration with python. I developed this to (integration)test https://github.com/cfn-sphere/cfn-sphere stacks configs within python scripts, instead of using bash.
The contained StackConfigHelper class is a python wrapper for syncing https://github.com/cfn-sphere/cfn-sphere
style stacks config to AWS.
It is like doing: cf sync -y cfn/dms.stacks.yaml in python.
Additionally you can change the stacks config programatically w/o changing
your config file.
Features
- renaming all stacks with a suffix cross referencing parameters between stacks will be renamed too
- adding or changing parameters of a stack
- getting outputs of a stack
- changing the region to deploy
- replacing tags
example usage
Create a config from a cfn-sphere yaml file with suffix the stacksnames with 'test':
from cfn_sphere_python.stack_config_helper import StackConfigHelper
config = StackConfigHelper(config_file='cfn/stacks.yaml', suffix='test')
to update some parameters call this
config.update_parameters('stack_basename', parameter_dict)
You can create the stacks (this is the same as calling cf sync cfn/stacks.yaml):
config.create_or_update_stacks()
To retrieve outputs of a stack:
config.get_stack_output('stack_basename','host')
To update all stack cross references:
config.update_references({'old_stackname': 'new_stackname'})
To delete all stacks:
config.delete_stacks()
