I am using docker for all my development. I used to have a ubuntu laptop for my primary development machine, now I switched to Mac. Performance is much slower on Mac though. For an app i managed to bind the volume as read-only as the PHP app is sandboxed and does not write to disk.

Recently out of private beta, Docker's new native applications aim to replace the current methods for running Docker on Windows and Mac, creating a better experience for developers using those platforms. For the previous solution, Docker Toolbox used VirtualBox to create a small Linux virtual machine that hosted your images and containers. It worked pretty well, but it could be unreliable at times and required workarounds that sometimes resulted in unexpected outcomes or didn't work at all. Docker for Mac removes the dependency on VirtualBox and instead uses virtualization technology that is already part of Mac OS X,.

Docker for Windows uses Microsoft's virtualization technology,. These changes aim to make your Docker containers run faster than before, take up less disk space, and fit better into your operating system. I am a Mac user, so I'll be focusing on the Mac version of Docker's new application, but I'll highlight any significant differences with the Windows version.

Best text to speech app for mac. On the Mac and Windows the 'desktop app' is more than just a shortcut to the website. Disconnect your wifi and close your default browser (set to clear cookies, offline data, active logins, cache, site preferences, browsing and download history).

Install and Setup Download the native application. Successive updates to the application have made the installation process and the resulting application increasingly 'more native' and better integrated with the operating system. Because the application uses newer technologies only available in newer machines and OS versions, it has minimum requirements, which are: Mac Minimum Requirements • A 2010 or newer model, with Intel's hardware support for memory management unit (MMU) virtualization. • OS X 10.10.3 Yosemite or newer, as the HyperVisor framework used is available in Yosemite onward. • At least 4GB of RAM. • VirtualBox prior to version 4.3.30 must not be installed, as it will cause issues with Docker for Mac. Windows minimum requirements • 64-bit Windows 10.

Co-Existing With Docker Toolbox If you are using Docker Toolbox, your images and containers can typically coexist together. This is thanks to Docker Toolbox using VirtualBox to host images and containers and installing command line tools to more 'Linux' path locations. Both Docker for Mac and Windows are fully native to the host platform and install everything into locations you would expect ( e.g., the Applications folder), only using symlinks to make certain tools accessible on the command line. When you first run the Docker application, it will check your system for compatibility and requirements, show a welcome screen, and then start the Docker process. Your main interaction with the Docker application will be via a menu bar item: To stop and start the Docker process, open Kitematic for GUI access to your containers, find documentation, and access preferences. Preferences and Configuration General The General pane has settings for configuring the specs of the virtual machine, updates, and excluding the virtual machine from backups (Mac only).

This is a simple but useful feature to have, as it can end up being a large file. Advanced Many enterprise users of Docker use their own registries for custom images. The advanced settings pane lets you define custom registries to search for images that you trust. The application should automatically detect any HTTP(s) proxy settings you have at an operating system level, but you can check them here.
