# ![Logo](cloudbender.png) CloudBender

# About

Toolset to deploy and maintain infrastructure in automated and trackable manner.  
First class support for:  
- [AWS CloudFormation](https://aws.amazon.com/cloudformation)
- [Pulumi](https://www.pulumi.com/docs/)


# Install

`$ pip install cloudbender`

# State management
## Cloudformation
All state is handled by AWS Cloudformation.  
The required account and region are determined by CloudBender automatically from the configuration.

## Pulumi
The state for all Pulumi resources are stored on S3 in your account and in the same region as the resources being deployed.
No data is send to nor shared with the official Pulumi provided APIs.

CloudBender configures Pulumi with a local, temporary workspace on the fly. This incl. the injection of various common parameters like the AWS account ID and region etc.

```

## Config management
- Within the config folder each directory represents either a stack group if it has sub-directories, or an actual Cloudformation stack in case it is a leaf folder.
- The actual configuration for each stack is hierachly merged. Lower level config files overwrite higher-level values. Complex data structures like dictionaries and arrays are deep merged.

## Quickstart
TBD

## Secrets handling

### Pulumi
CloudBender supports the native Pulumi secret handling.
See [Pulumi Docs](https://www.pulumi.com/docs/intro/concepts/secrets/) for details.

### Cloudformation
CloudBender supports [SOPS](https://github.com/mozilla/sops) to encrypt values in any config yaml file since version 0.8.1  

If a sops encrypted config file is detected CloudBender will automatically try to decrypt the file during execution.  
All required information to decrypt has to be present in the embedded sops config or set ahead of time via sops supported ENVIRONMENT variables.

SOPS support can be disabled by setting `DISABLE_SOPS` in order to reduce timeouts etc.
