RiakCS as registry storage


RiakCS is a S3 compliant object storage, based on the distributed database Riak by Basho. In case AWS S3 isn't an option RiakCS may be an alternative to run the storage in-house or locally as a developer.

Installing RiakCS locally

If you want to try it out locally, start with installing RiakCS using docker.

To run and start three buckets, do the following (check https://github.com/ianbytchek/docker-riak-cs for further info):

docker run --env 'RIAK_CS_BUCKETS=foo,bar,baz' --publish '8080:8080' --name 'riak-cs' ianbytchek/riak-cs

This will expose RiakCS on http://localhost:8080/. To be able to interact with the storage you need to get the access key and secret key. You will find this in the RiakCS log. To start with, find the containerid for the container that we named riak-cs:

docker ps

After RiakCS has started, which may take a minute or two, the keys will show up top of the log.

docker logs <containerid>

Starting a registry

Make sure you have installed the oc package and the Riak storage adapter.

npm install -g oc
npm install oc-riak-storage-adapter

Create an index.js file and add the access key and secret key to the snippet below.

'use strict';
const oc = require('oc');
const riak = require('oc-riak-storage-adapter');

let configuration = {
  verbosity: 5,
  baseUrl: 'http://localhost:3333',
  port: 3333,
  tempDir: './temp/',
  refreshInterval: 600,
  pollingInterval: 5,
  storage: {
    adapter: riak,
    options: {
      key: '<ACCESS KEY>',
      secret: '<SECRET KEY>',
      bucket: 'foo',
      region: 'us-east-1',
      componentsDir: 'components',
      signatureVersion: 'v2',       // Use v2 for RiakCS
      sslEnabled: false,
      path: 'http://localhost:8080/foo/',
      s3ForcePathStyle: true,       // Necessary to get the path right
      debug: true,                  // Log what AWS is up to to stdout
      // Override endpoint, this is passed straight to AWS.Endpoint constructor - https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Endpoint.html
      endpoint: 'http://localhost:8080'
  env: { name: 'production' }

let registry = new oc.Registry(configuration);

registry.start(function(err, app){
  if(err) {
    console.log('Registry not started: ', err);

Now start the registry:

node index.js

The registry should be now be exposed on http://localhost:3333/.

Publish a component

Go to the directory that contains the component you want to publish. First you have to add the registry by doing:

oc registry add http://localhost:3333/

Finally, to publish the component to the registry run

oc publish my-component/

Now the component should be available at http://localhost:3333/my-component.

Configuring endpoint

In the example above the full URL is used to specify the storage endpoint, ie http://localhost:8080. If the protocol is omitted, localhost:8080, the configuration will fallback to https.


If you run into trouble when accessing RiakCS the s3cmd can be a helpful companion. Install using pip, homebrew any other appropriate tool. See also https://github.com/s3tools/s3cmd/blob/master/INSTALL.

Create a file named s3.cfg and add the following snippet with your own access key and secret key:

access_key = <ACCESS KEY>
host_base = localhost:8080
host_bucket = foo
secret_key = <SECRET KEY>
signature_v2 = True

For example to list objects

s3cmd -c s3.cfg --no-ssl setacl --acl-public s3://foo/storage/components-details.json
