WordPress Docker - TechBar
http://www.techbar.me/wordpress-docker
November 23, 2013. September 20, 2014. You probably already heard about Docker and LXC containers. Also I wrote a post about LXC and how easy you can use it for testing here. So in this post I will not rewrite something that you already read on Docker website. There is a couple of those out there, but most of them are using just one container with bunch of processes in it. I think that idea about Docker is one processes per container. Why?

May 11, 2013. November 6, 2013. CephFS is only component of Ceph storage system that isn’t quite ready for production. However you need to give a try to that component. Ceph filesystem can be mounted on client in two ways:. As a kernel driver. So first on your Ceph cluster you need to add separate pool and key to be able to mount Ceph filesystem.

http://www.techbar.me/openstack-ceph-integration
May 14, 2013. November 1, 2013. Maybe most interesting part about Ceph is integration with OpenStack. So I will show that before moving forward to Ceph RadosGW. Before going through below instructions of OpenStack Ceph integration I assume that you have Ceph cluster up and running (Bobtail - ) and OpenStack (Folsom - ). Ceph uses block devices with OpenStack through libvirt which configures the QEMU interface to librbd. Two parts of OpenStack integrate with Ceph’s block devices:. Deb http:/ ceph.com/...
