Manta client tools

manta is a Node.js SDK for interacting with Joyent's Manta system.

This repository is part of the Joyent Manta project. See CONTRIBUTING.md for contribution guidelines.

Installation

$ npm install manta -g

Bash completion

Optionally install Bash completion. This is done by sourceing the "share/manta.completion" file that is installed with the tools. If you installed with npm install manta -g as above, then that is:

source $(npm prefix -g)/lib/node_modules/manta/share/manta.completion

Put that (or the equivalent) in your "~/.bashrc" file to make it permanent.

You can verify that completions are working by typing the TAB key with the following:

$ mls --<TAB>
--account   --insecure  --long      --role      --type      --verbose
--fulljson  --json      --marker    --subuser   --url       --version
--help      --keyId     --reverse   --time      --user

Usage

First setup your environment to match your Joyent Manta account:

$ export MANTA_KEY_ID=`ssh-keygen -l -f ~/.ssh/id_rsa.pub | awk '{print $2}' | tr -d '\n'`
$ export MANTA_URL=https://us-east.manta.joyent.com
$ export MANTA_USER=mark

Then a code snippet:

var assert = require('assert');
var fs = require('fs');
var manta = require('manta');

var client = manta.createClient({
    sign: manta.privateKeySigner({
        key: fs.readFileSync(process.env.HOME + '/.ssh/id_rsa', 'utf8'),
        keyId: process.env.MANTA_KEY_ID,
        user: process.env.MANTA_USER
    }),
    user: process.env.MANTA_USER,
    url: process.env.MANTA_URL
});
console.log('manta ready: %s', client.toString());

client.get('/mark/stor/foo', function (err, stream) {
    assert.ifError(err);

    stream.setEncoding('utf8');
    stream.on('data', function (chunk) {
        console.log(chunk);
    });
});

If your paths begin with '~~/' then manta will automatically fill in the current manta user, which helps you write more generic code since you get rid of the hardcoded user name. The following two rows are identical:

client.get('/mark/stor/foo', function (err, stream) {});
client.get('~~/stor/foo', function (err, stream) {});

CLI

Basic commands include:

1. mls - lists directory contents, default /:user/stor
2. mput - uploads data to a Manta object
3. mget - downloads an object from Manta
4. mjob - creates and runs a computational job on Manta
5. mfind - walks a Manta hierarchy to find names of objects by name, size, or type

A full set of commands for interacting with Manta is in bin.

Testing

Running this test suite will create files in Manta (using your current MANTA_* environment variables).

make test

The set of test files run can be filtered:

make test TEST_FILTER=muntar

As well, you can get debug/trace logging (note that we intentionally avoid LOG_LEVEL because the m* tools use that and sharing the same envvar can break tests):

make test TEST_LOG_LEVEL=trace 2>&1 | bunyan

There is a mechanism to re-build and test with a number of installed node versions. First you must create "test/node.paths" (based on "test/node.paths.example") and then:

make testall

Release process

Here is how to cut a release:

1. Make a commit to set the intended version in "package.json#version" and changing ## not yet released at the top of "CHANGES.md" to:

   ## not yet released
   
   
   ## $version
   

2. Get that commit approved and merged via https://cr.joyent.us, as with all commits to this repo. See the discussion of contribution at the top of this readme.

3. Once that is merged and you've updated your local copy, run:

   make cutarelease
   

   This will run a couple checks (clean working copy, versions in package.json and CHANGES.md match), then will git tag and npm publish.
