prpl = parameters pull tool

prpl is a tool running command with parameters that stored in AWS SSM Parameter Store.

The parameters are exported as environment variables.

Synopsis

If you have parameters such as:

• /my-app/staging/creds/id
• /my-app/staging/creds/password

then run command below and get a result:

prpl -path /my-app/staging env
# CREDS_ID=<ID>
# CREDS_PASSWORD=<PASSWORD>

Environment variable named in below rules:

• Remove -path value from full parameter path
  • prpl considers -path as a prefix and parameters can be unique without common prefix
  • environment variables names should not have environment name (such as staging) for convinience
    • parameters typically have environment in prefix
    • the app may refers environment variables such as CREDS_ID not MY_APP_STAGING_CREDS_ID
• Replace all characters except for alphabets or numbers with underscore (_)
• Convert characters to upper cases
