rethinkdb-pull v2.3.6

RethinkDB Pull

• Prompts for local and remote db/password info if none provided in options argument or .env file
• Uses ssh-tunnel to connect to a remote RethinkDB server
• Downloads a compressed file containing a database from the server
• Extracts the file and imports the tables into a local database, overwriting existing data unless merge option is true

Requirements

• rethinkdb: The Python version (sudo pip install rethinkdb)
• node.js >= 4

Usage

Put the following in a file within your project (e.g. pull.js):

const rethinkdbPull = require('rethinkdb-pull');

// Using minimum required settings
rethinkdbPull({
  tunnel: {
    username: 'somebody',
    host: 'example.com'
  }
})
.then(() => console.log('Hooray, I finished!'));

Add an npm script to package.json:

{
  "scripts": {
    "db:pull": "node ./pull.js"
  }
}

On the command line:

npm run db:pull

Returns

The rethinkdbPull function returns a Promise.

The Promise is resolved with a settings object, which is the result of merging per-call settings, environment variables, and default settings.

Settings

Available settings, with their defaults:

let settings = {
  localDb: undefined, // String
  localPwd: undefined, // String
  remoteDb: undefined, // String or Array
  remotePwd: undefined,
  tempDir: '/tmp',
  includeTables: [],
  excludeTables: [],
  force: false, // if true, skips inquirer prompts that would otherwise appear
  fetchOnly: false, // [ *see more below ]
  fetchToPath: '/tmp/rethink_dump.tar.gz', // if fetchOnly is true, path of the tarball to save
  // See https://github.com/agebrock/tunnel-ssh for details on tunnel settings:
  tunnel: {
    username: undefined,
    host: undefined,
    port: 22,
    dstHost: '127.0.0.1',
    dstPort: 28015,
    localHost: '127.0.0.1',
    localPort: 9999,
    keepAlive: true,
  }
}

* fetchOnly may be useful as a backup strategy. If set to true, the function call will only dump the remote db, NOT restore into a local db. The resulting file will be saved as: [tempDir]/[timestamp]/rethink_dump.tar.gz.

Database and password settings

• If you don't include values for localDb, localPwd, remoteDb, or remotePwd, you will be prompted to do so.
• Instead of passing these settings into the function argument, you may use .env settings:

  DB_NAME # localDb
  LOCAL_DB_ADMIN_PASSWORD # localPwd
  REMOTE_DB_NAME # remoteDb
  REMOTE_DB_ADMIN_PASSWORD # remotePwd

• If you pass in remoteDb as an array, you will be prompted to choose one of the array elements when the script is run.
