Bookshelf conforms the S3 api, so it's possible to use S3 itself instead of bookshelf.

See the bookshelf options here: http://docs.opscode.com/config_rb_chef_server_optional_settings.html#bookshelf

You'll want to set the bookshelf url to point to an S3 bucket and set the access and secret keys appropriately, then do a chef-server-ctl reconfigure so the settings are picked up and you should be good to go.

At that point you can even disable the bookshelf service if you want, as the server will pick up the settings and talk directly to S3, so bookshelf itself doesn't have to be running.

Hi Adam,

Thank you!

One more question, is it possible to use S3 as a bookshelf service? 

Regards,

Tetsu

No, Bookshelf doesn't sync the data for you. That configuration option maps to the HA configuration of Enterprise Chef, and it essentially disables the service by default and hands control over its state to a supervisor. We use DRBD to replicate the block device between two nodes, and keepalived to transition a VIP between them.

Hello,

According to document[1] of Chef 11 Server, there is an option in Bookshelf part

bookshelf['ha'] :  Use to run the Chef server in a high availability topology. Default value: false.

What does this mean? Does the HA here mean we can setup a bookshelf cluster with multiple nodes running Bookshelf service and Bookshelf will sync data (replica) automatically for us?
If it is true, how can I specify nodes in the cluster?
If it is false, how can I set up a cluster of Bookshelf ?
Can I use other S3 service instead of Bookshelf ?

Thank you for your help.

Regards,

Tetsu
