Nuxeo CloudBinaryManager

This addon provides implementations of Nuxeo's BinaryManager that stores binaries in cloud storage services. Currently there are two implementations available:

Amazon S3 storage: http://aws.amazon.com/s3/
Scality storage: http://www.scality.com/

For efficiency, a local disk cache (with limited size) is also used.

S3 configuration

To configure the S3 addon you will need a custom template including a modified default-repository-config.xml file with the following line:

<binaryManager class="org.nuxeo.ecm.core.storage.sql.S3BinaryManager" />

in the innermost "repository" section.

You will also need to make some additions to your nuxeo.conf file:

Be sure to protect your nuxeo.conf readable only by the nuxeo user as the file will have your AWS identifiers.

Mandatory parameters

nuxeo.s3storage.bucket : the name of the S3 bucket (unique across all of Amazon, find something original!)
nuxeo.s3storage.awsid : your AWS_ACCESS_KEY_ID
nuxeo.s3storage.awssecret : your AWS_SECRET_ACCESS_KEY

Optional parameters

nuxeo.s3storage.region : the region code your S3 bucket will be placed in. For us-east-1 (the default), don't set this parameter For us-west-1, use us-west-1 For eu-west-1, use EU For ap-southeast-1, use ap-southeast-1
nuxeo.s3storage.cachesize : size of the local cache (default is 100MB).

Crypto parameters

With S3, you have the option to store your data encrypted. Note that the local cache will NOT be encrypted.

The S3 binary manager can use a keystore containing a keypair, but there are a few caveats to be aware of :

The Sun/Oracle JDK doesn't always allow the AES256 cipher which the AWS SDK uses internally. Depending on the US export restrictions for your country, you may be able to modify your JDK to use AES256 by installing the "Java Cryptography Extension Unlimited Strength Jurisdiction Policy Files". See the following link to download the files and installation instructions: http://www.oracle.com/technetwork/java/javase/downloads/index.html
Don't forget to specify the key algorithm if you create your keypair with the "keytool" command, as this won't work with the default (DSA). The S3 Binary Manager has been tested with a keystore generated with this command : keytool -genkeypair -keystore </path/to/keystore/file> -alias -storepass -keypass -dname -keyalg RSA

With all that preceded in mind, here are the crypto options (they are all mandatory once you specify a keystore) :

nuxeo.s3storage.crypt.keystore.file : the absolute path to the keystore file
nuxeo.s3storage.crypt.keystore.password : the keystore password
nuxeo.s3storage.crypt.key.alias = the key alias
nuxeo.s3storage.crypt.key.password = the key password

Scality configuration

To configure the Scality addon you will need a custom template including a modified default-repository-config.xml file with the following line:

<binaryManager class="org.nuxeo.ecm.core.storage.sql.ScalityBinaryManager" />

in the innermost "repository" section.

You will also need to make some additions to your nuxeo.conf file:

parameters

Be sure to protect your nuxeo.conf readable only by the nuxeo user as the file will have your Scality identifiers.

nuxeo.scality.awsid - your Scality identifier
nuxeo.scality.awssecret - your Scality passphrase
nuxeo.scality.region - preferred storage region (e.g. US)
nuxeo.scality.bucket - the name of the Scality bucket
nuxeo.scality.cache.size - size of the local cache (e.g. 100MB)
nuxeo.scality.host.name - the hostname on the Scality system
