CFTool

A Tool For Managing AWS CloudFormation Stacks.

Dependencies

• Requires the Racket programming language if building from source.
• Standalone executable requires awscli to run commands. Assumes you have already set up your awscli profiles.

Once compiled the standalone executable has no dependencies besides the awscli.

Install Instructions

Standalone executable (Github releases)

Download the latest executable from repo’s releases and add it somewhere in your path.

Debugging Your CFTool Config

If you provide the -D (short form of --dry-run) flag to cftool, it will print the awscli commands which will be called to perform the requested action, instead of running the commands. This can be quite useful when trying to debug an error (e.g incorrect stack params), or check that a new definition in the config results in sensible looking commands, before running it for real on the specified environment/account.

NOTE: There is some parameter quote/escape handling done under the hood for the calls to awscli. This means that some of the commands output by -D will not “just work” if you copy paste them into a terminal. This is because the -D flag does not currently print the parameters pre-wrapped in quotes.
