OVERVIEW Docker is the company driving the container movement and the only container platform provider to address every application across the hybrid cloud. Today’s businesses are under pressure to digitally transform but are constrained by existing applications and infrastructure while rationalizing an increasingly diverse portfolio of clouds, datacenters and application architectures. Docker enables true independence between applications and infrastructure and developers and IT ops to unlock their potential and creates a model for better collaboration and innovation. A little intro to LXC: - LXC (LinuX Containers) is a OS-level virtualization technology that allows creation and running of multiple isolated Linux virtual environments (VE) on a single control host. These isolation levels or containers can be used to either sandbox specific applications, or to emulate an entirely new host. LXC uses Linux’s cgroups functionality, which was introduced in version 2.6.24 to...

Single Node Ceph Install A quick guide for installing Ceph on a single node for demo purposes. It almost goes without saying that this is for tire-kickers who just want to test out the software. Ceph is a powerful distributed storage platform with a focus on spreading the failure domain across disks, servers, racks, pods, and datacenters. It doesn’t get a chance to shine if limited to a single node. With that said, let’s get on with it. Inspired from:  http://palmerville.github.io/2016/04/30/single-node-ceph-install.html Hardware This example uses a VMware Workstation 11 VM with 4 disks attached (1 for OS/App, 3 for Storage). Those installing on physical hardware for a more permanent home setup will obviously want to increase the OS disks for redundancy. To get started create a new VM with the following specs: ·         Name: ceph-single-node ·         Type: Linux ·     ...
