Install

npm install cfnmate
npx cfnmate --help

cfnmate needs cfnmate.config.js - a descriptor to deploy stack

Basic Example

Prepare dir with:

• my-template.yaml that needs parameter "Env"
• cfnmate.config.js

module.exports = (params) => ({
  stackName: `my-stack-${params.Env}`
})

Command:

cfnmate deploy my-template.yaml Env=dev

Apply template transformations

const { resourceTransform } = require('cfnmate/plugins')
module.exports = ({ Env, Bucket, Version }) => ({
  stackName: `my-stack-${Env}`,
  plugins: [
    resourceTransform({
      LambdaFunction({ Properties }) {
        Properties.Code = {
          S3Bucket: `${Bucket}-${Env}`,
          S3Key: Version
        }
      }
    })
  ]
})

Command:

cfnmate deploy my-template.yaml Env=dev Bucket=my-bucket Version=1.0

Dependency - deploy another stack before yours

plugins: [
  dependency('../path/to/another/template.taml', {
    ParamForDependency: 'value'
  })
]
