• To restart an existing template, run:

  make up t=<template-folder-name>
  

• Example:

  make up t=custom-react-agent
  

  OR

  template=custom-react-agent docker-compose --env-file .env up -d
  

• To build a new template, run:

  make down t=<old-template-folder-name>
  make build t=<new-template-folder-name>
