Once again, Docker has set its sights a little wider by acquiring an outside firm. But the acquired company doesn’t ease the use of Docker on the server, Docker’s typical stomping ground. Rather, it focuses on using Docker on Mac desktops — and soon Windows.Kitematic, an open source tool, allows developers to create and deploy Docker containers on Macs using a graphical interface. The user’s system is configured to run Docker containers, which can then be pulled from Docker Hub and set up with various automation features, such as automapping of network ports and drive volumes. The completed containers can be run in much the same manner as one might download and launch a VM appliance in VMware Desktop. (Kitematic uses VirtualBox to run a container host.)
