To convert from YAML to JSON
All of the Cloudformation files here are in Yaml.
To convert them to Json, Amazon provide the 'aws-cfn-template-flip' tool. This has been dockerized already, so to convert the cloudformation.yaml files into cloudformation.json, 'cd' the folder containing the cloudformation.yaml file and then:
From PowerShell:
docker run -it --rm -v ${pwd}:/workdir joshdvir/aws-cfn-template-flip -j /workdir/cloudformation.yaml > cloudformation.json
From Cmdprompt:
docker run -it --rm -v %CD%:/workdir joshdvir/aws-cfn-template-flip -j /workdir/cloudformation.yaml > cloudformation.json
From Shell:
docker run -it --rm -v .:/workdir joshdvir/aws-cfn-template-flip -j /workdir/cloudformation.yaml > cloudformation.json
