cluster-accounts

This package adds support for accounts/authentication in meteorhacks:cluster

Getting Started

meteor add ozsay:cluster-accounts

If meteorhacks:cluster is not installed in your project, It will install it has a dependency.

Usage

Please read the instructions at meteorhacks:cluster for how to setup the cluster.

After you setup the cluster in your projects you need to define the meteor app that manages all the user accounts (could be the web service or a dedicated service). From now on we will refer to that app as the provider since it provides the logged in users collection. All the other apps in your cluster that depend on cluster-accounts are the consumers.

Setup a provider

First, you need to define a string that will be a secret.

You can define it via environment variable: export CLUSTER_ACCOUNTS_SECRET=this_is_a_secret or programmatically Cluster.setAccountsSecret('this_is_a_secret').

It is very important that you don't expose this string to your users, because we use this string to authenticate a node in the cluster when we subscribe a consumer to the logged in users collection.

Then start the provider with Cluster.startProvider().

Setup a consumer

First, define the secret as you did with the provider.

The secret must be identical in all of your consumers.

Then set the connection to the provider with Cluster.setAccountsConnection(connection).

example:

    var connection = Cluster.discoverConnection("web");

    Cluster.setAccountsConnection(connection);

And finally start the consumer: Cluster.startConsumer().

Logging

By default, the packages writes logs to the console. You can override this behavior by setting a different logger via Cluster.setAccountLogger.

The package writes logs about the following events:

Provider:

1. When the provider has been successfully created (info).

Consumer:

1. When the consumer has been successfully created (info).
2. When a user has been logged in (debug).
3. When a user has been logged out (debug).

How it works

• When you start the provider it will create a collection in the server of the logged in users.
• When you start a consumer it will subscribe to the logged in users collection that exists in the provider.
• When a client performs a login to the web service, cluster-account automatically will perform a login to each of the connected cluster nodes.
