Install Docker for Mac Estimated reading time: 3 minutes Docker for Mac is the of Docker for MacOS. To download Docker for Mac, head to Docker Store. What to know before you install README FIRST for Docker Toolbox and Docker Machine users If you are already running Docker on your machine, first read to understand the impact of this installation on your existing setup, how to set your environment for Docker for Mac, and how the two products can coexist. Relationship to Docker Machine: Installing Docker for Mac does not affect machines you created with Docker Machine. You have the option to copy containers and images from your local default machine (if one exists) to the new Docker for Mac VM. When you are running Docker for Mac, you do not need Docker Machine nodes running at all locally (or anywhere else).

With Docker for Mac, you have a new, native virtualization system running (HyperKit) which takes the place of the VirtualBox system. To learn more, see. System Requirements: Docker for Mac launches only if all of these requirements are met.

Mac hardware must be a 2010 or newer model, with Intel’s hardware support for memory management unit (MMU) virtualization, including Extended Page Tables (EPT) and Unrestricted Mode. You can check to see if your machine has this support by running the following command in a terminal: sysctl kern.hvsupport. macOS El Capitan 10.11 and newer macOS releases are supported. We recommend upgrading to the latest version of macOS.

At least 4GB of RAM. VirtualBox prior to version 4.3.30 must NOT be installed (it is incompatible with Docker for Mac). If you have a newer version of VirtualBox installed, it’s fine. Note: If your system does not satisfy these requirements, you can install, which uses Oracle VirtualBox instead of HyperKit. What the install includes: The installation provides, Docker CLI client,.

Install and run Docker for Mac. Double-click Docker.dmg to open the installer, then drag Moby the whale to the Applications folder. Double-click Docker.app in the Applications folder to start Docker. (In the example below, the Applications folder is in “grid” view mode.) You are prompted to authorize Docker.app with your system password after you launch it. Privileged access is needed to install networking components and links to the Docker apps. The whale in the top status bar indicates that Docker is running, and accessible from a terminal.

If you just installed the app, you also get a success message with suggested next steps and a link to this documentation. Click the whale ( ) in the status bar to dismiss this popup. Click the whale ( ) to get Preferences and other options. Select About Docker to verify that you have the latest version. You are up and running with Docker for Mac. Where to go next. provides an overview of Docker for Mac, basic Docker command examples, how to get help or give feedback, and links to all topics in the Docker for Mac guide.

How To Get Xdebug Working With Docker For Mac

describes common problems, workarounds, how to run and submit diagnostics, and submit issues. provides answers to frequently asked questions. lists component updates, new features, and improvements associated with Stable releases (or ). provides a general Docker tutorial.,.

Note: The setup that I am going to use is for demonstration purposes only! I do not recommend that you use it 'as is' as your development setup. Some problems that I won't solve here include:.

everything is owned by root (no dedicated user; that will in particular be problematic for linux users). SSH login credentials are hard-coded in the container (inherently insecure). host.docker.internal will only exist for Windows and Mac users, NOT for unix users There will be a another part of this series that will deal with all of those (and some more common) problems and aims at providing a consistent development environment for all developers in a team (regardless of the OS they are using). Please subscribe to the to get automatic notifications when that part comes out:) Table of contents. Setup: The docker containers We will only need the php-cli container for this part. Luckily, we already have a good understanding on how to create the container, although we'll need to make some adjustments to make everything work smoothly with PhpStorm. I'm gonna walk you through all the necessary changes, but I'd still recommend to clone the corresponding git repository (unless you've already done that in part 1), checkout branch and build the containers now.

As in part 1, I'm assuming your codebase lives at /c/codesbase: cd /c/codebase/ git clone cd docker-php-tutorial git checkout part2 docker-compose docker-compose build Further, make sure to open /c/codebase/docker-php-tutorial as a project in PhpStorm. In general, there are two ways to run PHP from PhpStorm using Docker:.

via the built-in Docker setup. via Deployment Configuration (treating docker more or less like a VM) Run PHP via built-in Docker setup This is the 'easier' way and should mostly work 'out of the box'. When you run a PHP script using this method, PhpStorm will start a docker container and configure it automatically (path mappings, network setup.).

Next, the script in question is executed and the container is stopped afterwards. Enable docker to communicate on port 2375 Open the Docker Setting in tab 'General' and activate the checkbox that says 'Expose daemon on tcp://localhost:2375 without TLS'. Configure Docker Server in PhpStorm In PhpStorm, navigate to File Settings Build, Execution, Deployment Docker. Fill out Name and Engine API URL:. Name: Docker. Engine API URL: tcp://localhost:2375 PhpStorm will automatically validate your settings and show a 'Connection successful' info below the path mappings box: Configure Docker PHP CLI Interpreter Navigate to File Settings Languages & Frameworks PHP.

Click on the three dots '.' Next to 'CLI Interpreter'.

In the newly opened pop up click on the '+' sign on the top left and choose 'From Docker,Vagrant,VM,Remote.' Next, choose 'Docker' from the radio buttons and select our previously created Docker server (named 'Docker'). As image, choose docker-php-tutorialdocker-php-cli:latest (which is one of the images used in this tutorial). If you don't see this image you've probably not yet built the containers. In that case, please checkout the repo and build the containers: cd /c/codebase/ git clone cd docker-php-tutorial git checkout part2 docker-compose docker-compose build PhpStorm will now try to create the container and figure out if it can run PHP. If all goes well, you should see the following screenshot with information about the PHP and Xdebug versions in the image/container. Note: Sometimes, this does not work immediately.

If that's the case for you, try to click the 'Refresh' icon next to 'PHP executable'. After you hit 'OK', you'll be back in the PHP Interpreter screen where our newly configured Docker interpreter should be already selected: Note that PhpStorm has automatically configured the path mappings as -v command line option for the Docker container. After hitting 'OK' one last time, everything is set up. Run/debug a php script on docker To verify that everything is working, open the file app/hello-world.php in PhpStorm, right click in the editor pane and choose 'Run'.

PhpStorm will start the configured container and run the script. The output is then visible at the bottom of the IDE: Since we're using an image that has Xdebug installed, we can also set a breakpoint and use 'Debug' instead of 'Run' to trigger a debug session: PhpStorm should stop on the marked line. When you take a look at the 'Console' panel at the bottom of the IDE, you should see something like this: docker://docker-php-tutorialdocker-php-cli:latest/php -dxdebug.remoteenable=1 -dxdebug.remotemode=req -dxdebug.remoteport=9000 -dxdebug.remotehost=192.168.10.1 /opt/project/app/hello-world.php Please keep the -dxdebug.remotehost=192.168.10.1 option in mind - this will be 'interesting' when we set up a Docker-based PHP Interpreter via Deployment Configuration;) PS: You find the official documentation for the built-in Docker support at. Run PHP on Docker via Deployment Configuration The previously explained method is nice, but it is lacking flexibility and it's also pretty slow as the container used to run the script needs to be started each time we want to execute something. Luckily, there is an additional way of running PHP scripts on Docker in PhpStorm, which is closely related to the Vagrant setup that I explained in. To make this work, we will keep a docker container running all the time and configure PhpStorm to connect to it via SSH. Thus, PhpStorm effectively treats the docker container as any other remote host.

Preparing the 'workspace' container Please make sure to checkout my demo repository and switch to the correct branch first: cd /c/codebase/ git clone cd docker-php-tutorial git checkout part2 For now, we only need the php-cli container. In it, we need to setup the xdebug extension (already done and explained in the previous part) and an SSH server so that we can log in via SSH.
