This message shows that your installation appears to be working correctly. • Start a Dockerized web server.

Like the hello-world image above, if the image is not found locally, Docker pulls it from Docker Hub. $ docker run --detach --publish =80:80 --name =webserver nginx • In a web browser, go to to view the nginx homepage. Because we specified the default HTTP port, it isn’t necessary to append:80 at the end of the URL. Early beta releases used docker as the hostname to build the URL. Now, ports are exposed on the private IP addresses of the VM and forwarded to localhost with no other host name set. • View the details on the container while your web server is running (with docker container ls or docker ps): $ docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 90 nginx 'nginx -g 'daemon off' About a minute ago Up About a minute 0.0.0.0:80->80/tcp, 443/tcp webserver • Stop and remove containers and images with the following commands.

This path comes from Docker Host (not from MacOS) fefore 'Docker for Mac Application' times, where where was a VirtualBox VM 'default' and inside this VM mentioned path exists (for sure), now in 'Docker for Mac Application' times there is a Docker.qcow2 image, which is qemu base vm. If you are already running Docker on your machine, first read Docker for Mac vs. Docker Toolbox 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. System Requirements: Docker for Mac launches.

Use the “all” flag ( --all or -a) to view stopped containers. $ docker container ls $ docker container stop webserver $ docker container ls -a $ docker container rm webserver $ docker image ls $ docker image rm nginx Preferences menu Choose → Preferences from the menu bar and configure the runtime options described below. General General settings are: • Start Docker when you log in: Uncheck this option if you don’t want Docker to start when you open your session. • Automatically check for updates notifies you when an update is available. Click OK to accept and install updates (or cancel to keep the current version).

If you disable this option, you can still find out about updates manually by choosing → Check for Updates. • Include VM in Time Machine backups backs up the Docker for Mac virtual machine. (Disabled by default.) • Securely store Docker logins in MacOS keychain stores your Docker login credentials. (Enabled by default.) • Send usage statistics — Send diagnostics, crash reports, and usage data to Docker. This information helps Docker improve the application and get more context for troubleshooting problems. (Enabled by default.) File sharing Choose which local directories to share with your containers.

File sharing is required for volume mounting if the project lives outside of the /Users directory. In that case, share the drive where the Dockerfile and volume are located. Otherwise, you get file not found or cannot start service errors at runtime.

File share settings are: • Add a Directory: Click + and navigate to the directory you want to add. • Apply & Restart makes the directory available to containers using Docker’s bind mount ( -v) feature. There are some limitations on the directories that can be shared: • They cannot be a subdirectory of an already shared directory. • They cannot already exist inside of Docker. For more information, see: • in the topic on. •.) Advanced On the Advanced tab, you can limit resources available to Docker.

Advanced settings are: CPUs: By default, Docker for Mac is set to use half the number of processors available on the host machine. To increase processing power, set this to a higher number; to decrease, lower the number.

Memory: By default, Docker for Mac is set to use 2 GB runtime memory, allocated from the total available memory on your Mac. To increase RAM, set this to a higher number; to decrease it, lower the number. Swap: Configure swap file size as needed. The default is 1 GB. Disk Specify the Disk image location of the Linux volume, where containers and images are stored. You can also move the disk image location.

Dual booting, virtualization, and building out the Linux environment on OS X are discussed in detail, along with a comparative view of well–known Mac tools and their open source equivalents. Written for daily use, this concise and dependable guide will steer you across the technical landscape from your chosen Linux flavor to the OS X promised land. • Live with OS X, but work with Linux tools • Make the OS X–Linux hybrid a reality • Use Mac tools where possible and free software where appropriate.
