Owncloud - Minio External Storage

By default Owncloud uses signature version 2 in authenticating to AWS api service. It can only be overridden to use v4 if region set is either eu-central-* or cn-*. Minio in contrary only supports version 4 and only validates us-east-1 / US region (at least for now). So a quick fix to go around this issue is to let Owncloud use signature v4 if the region set is us-east-1.

However this may require another modification if Minio decided to support any other regions aside from the existing one. A much better approach maybe is to add a flag or an option to trigger it's backend service to use the appropriate signature version, perhaps a checkbox in it's GUI and then update the backend service accordingly.

Description:

Updated the official Ownclouds docker image to use signature version 4 in authenticating to AWS S3 api service if region set is us-east-1.

Modifications:

         $requiresV4 = !$currentValue
             && isset($config['region'])
             && (strpos($config['region'], 'eu-central-') === 0
-                || strpos($config['region'], 'cn-') === 0);
+                || strpos($config['region'], 'cn-') === 0
+                || strpos($config['region'], 'us-east-') === 0);

Installation:

$ docker build -t owncloud/minio .
$ docker run -d -p 80:80 owncloud/minio:latest

Or pull from quay.io

docker pull quay.io/acaleph/owncloud:latest
docker run -d -p 80:80 quay.io/acaleph/owncloud:latest

Configuring Owncloud to Use Minio:

First, need to enable the External storage support module/app. Should be at Apps > Not enabled > External Storage Support. Then under Admin page, Enable User External Storage should be checked and then configure External storage (Amazon S3 type). For more details please check on the following links:

• Enabling external storage support module/app
• Adding external storage

Example:

Folder name: Minio 
External storage type: Amazon S3
Bucket: myBucket
Hostname: minio.public.fqdn
Port: 12345
Region: us-east-1
Enable Path Style: (checked)
Access Key: S2M7XKJ1U***********
Secret Key: nUSjs2eGnvWi9kX4zzIBAoL*****************

If for instance myBucket is non-existent, then it will be created automatically. Hostname could also be the associated domain name of the minio service while port is the internal port. Thus it could be changed to:

...
Hostname: minio-internal
Port: 9000
