Using the tool

TL;DR demo

Clone this repo, cd into it, start Docker, run the following:

docker run -it -v ${PWD}/configurations:/confs anyxo/fafafa /confs/minimal.yml

Running with Swift

Clone this repo, cd fafafa, run swift run <config.yml>

Running with Docker

• create a local folder for your configuration input and output, e.g.

  • mkdir myconfig

• put your input configuration file into that folder, e.g.

  • mv serverless.yml myconfig

• run the Docker image, mapping your folder into the container, e.g.

  • docker run -it -v ${PWD}/myconfig:/myconfig fafafa /myconfig/serverless.yml -o /myconfig/serverless_modified.yml

A few things to note here:

• -it is needed because this command requires an interactive shell
• -v needs absolute paths to work correctly (the example uses ${PWD} for convenience
• -o and an output file can be omitted (then the result is printed to the console)

Additionally, please note that some functionality (currently wildcard pattern matching) is limited to macOS
