ssm-to-heroku-env-action

GitHub Action that sets Heroku environment variables from AWS SSM Parameter Store. This Action was created to efficiently synchronize when using the same environment variables on AWS and Heroku.

Inputs

Input	Required	Default	Info
path	Yes	N/A	The path to the environment variable in the AWS SSM Parameter Store that you want to set in Heroku
email	Yes	N/A	Heroku email
token	Yes	N/A	Heroku token
app	Yes	N/A	Heroku app name

And you need to set AWS credentials by using like AWS Credentials for GitHub Actions.

Description

First of all, this actions retrieve environment variables from AWS SSM Parameter Store specifying path input. This mean when you set like under CLI command, you can retrieve under '/test/'　recursively if you specified path as '/test/'.

aws ssm put-parameter \
    --name "/test/VALUE1" \
    --value "test1" \
    --type String \
    --region "ap-northeast-3"

Authentication to heroku is done by writing email and token in the .netrc file as written in the Heroku CLI Authentication.You can get your token from here. And you need to set your app name to app input.
