💥 cf-merge

cf-merge brings import syntax to CloudFormation templates. Split up and modularize your stacks!

Example

Use top-level imports to merge in other templates:

``yaml


@import ./networking.yml

AWSTemplateFormatVersion: 2010-09-09
Parameters:
- foo
Resources:
- bar
`

Use inline imports to merge in sections of other templates:

`yaml
AWSTemplateFormatVersion: 2010-09-09
Parameters:
- foo
# @import ./ec2_instances.yml#Parameters
Resources:
- bar
# @import ./ec2_instances.yml#Resources
`

See the tests to see examples of this in action.

Usage

cf-merge is distributed as a nodejs package. You can install it via npm or yarn:

`sh
yarn add @magicmark/cf-merge
`

You can then call cf-merge in your bash script when calling aws cloudformation deploy:

`sh
aws cloudformation deploy \
--region $REGION \
--profile $CLI_PROFILE \
--stack-name $STACK_NAME \
--template-file "$(yarn cf-merge main.yml --tmpfile)" \
`
