    • -r --run
    • -e --export-env

##Installation

npm install -g geppetto

##Usage

If you have a geppetto.json in the local directory, you can just run geppetto. If you have a file named something other than geppetto.json use the -f or --file flag.

geppetto -f config.json

Define a json configuration file with the processes that you want running. You can define a:

• Required
  • command - The command being called to launch the process
• Optional
  • dir - The directory you want the process to be launched from. dir supports $ENVIRONMENT variable expansion.
  • env - A hash of process specific environment variables you want the process to have
  • install - A sub level of options to perform to install the necessary files (if dir is nonexistent)for the process (install overrides git option)
  • postinstall - A sub level of options to perform after installation
  • git - If dir is nonexistent it will be cloned down locally
  • postgit - Sub level options to run on directory after cloning down with git

{
  "api_server": {
    "dir": "$PWD/node-server",
    "install": {
      "command": "curl",
      "arguments": ["-O", "https://example.com/api_server"]
    },
    "postinstall": {
      "command": "npm",
      "arguments": ["install"]
    },
    "command": "node",
    "arguments": [ "app.js" ],
    "env": {
      "PORT": "1337"
    },
  },
  "app_server": {
    "git": "https://github.com/me/app_server",
    "postgit": {
      "command": "bundle",
      "arguments": ["install"]
    },
    "command": "rails",
    "arguments": ["s"],
    "env": {
      "API_URL": "http://localhost:1337"
    }
  }
}

###Common Globals There are also top level keys that can be defined to set global common options:

• _env Common environment variables for each service

{
  "_env": {"LEVEL": "1", "BOSS": "SnapBack"},
  "game": {"command": "cat", "arguments": ["index.js"], "env": {"LEVEL": "2"}}
}
//game env will be `{LEVEL: 2, BOSS: "SnapBack"}

###Commands

-r --run

You can run select services from a configuration file by passing in the -r or --run flag specifying which services.

geppetto -r worker -r webapp -r proxy

-e --export-env

You can "export" the environment variables for an app using a -e or --export-env flag and an optional app name.

geppetto -e [app-name]

If no app is specificed all _env values will be printed, if an app is specified its specific env variables will be printed as well. You can pipe these into a file and source it in bash.

Example output:

export SOME_ENV=your_value
export SOME_OTHER_ENV=your_other_value
