<p>My mate Dom introduced me to Docker a couple of months ago, but it took me some time for the power of this technology to sink in.</p><p>Docker is a container platform for Linux that allows individual applications to be sandboxed and run independently. This is similar to machine virtualisation, but is done at the application level not at the OS-level. This means that each container can contain all necessary dependencies, but does contain the operating system itself. This allows for much smaller sandboxes, which are less resource intensive than VMs.</p>
