Docker 1.12.1; Docker machine 0.8.1; Linux kernel 4.4.20; aufs 20160905; Bug fixes and minor changes. Fixed communications glitch when UI talks to com.docker.vmnetd Fixes docker/for-mac#90. Docker-diagnose: display and record the time the diagnosis was captured. Don't compute the container folder in com.docker.vmnetd Fixes docker/for. Docker Desktop is an application for MacOS and Windows machines for the building and sharing of containerized applications and microservices. Docker Desktop delivers the speed, choice and security you need for designing and delivering containerized applications on your desktop. Oct 06, 2016. DockerCon 2016 introduced us to a new version of the Docker Engine: 1.12. There are some major updates included in this release. So many, in fact, that in talking to other Meetup organizers around the globe it became apparent that a dedicated session to discuss 1.12's launch and features is valuable. For this week's Docker Online Meetup, Docker Captains Ajeet Singh Raina, Viktor Farcic and Bret Fisher shared their tips and tricks for built In Docker orchestration. Ajeet talked about the best ways to use Docker 1.12 Service.

If you already have an installation of Docker Toolbox, read these topicsfirst to learn how Docker Desktop on Mac and Docker Toolbox differ, and how they cancoexist.
The Docker Toolbox environment
Docker Toolbox installs docker, docker-compose, and docker-machine in/usr/local/bin on your Mac. It also installs VirtualBox. At installation time,Toolbox uses docker-machine to provision a VirtualBox VM called default,running the boot2docker Linux distribution, with Docker Enginewith certificates located on your Mac at$HOME/.docker/machine/machines/default.
Before you use docker or docker-compose on your Mac, you typically use thecommand eval $(docker-machine env default) to set environment variables sothat docker or docker-compose know how to talk to Docker Engine running onVirtualBox.
This setup is shown in the following diagram.
The Docker Desktop on Mac environment
Docker Desktop on Mac is a Mac-native application, that you install in /Applications.At installation time, it creates symlinks in /usr/local/bin for docker anddocker-compose and others, to the commands in the applicationbundle, in /Applications/Docker.app/Contents/Resources/bin.
Here are some key points to know about Docker Desktop on Mac before you get started:
Instant effect 1 1 1 – filter your images transparent. Docker Desktop uses HyperKit instead of Virtual Box. Hyperkit is a lightweight macOS virtualization solution built on top of Hypervisor.framework in macOS 10.10 Yosemite and higher.
When you install Docker Desktop on Mac, machines created with Docker Machine are not affected.
Docker Desktop does not use
docker-machineto provision its VM.The Docker Engine API is exposed on asocket available to the Mac host at/var/run/docker.sock. This is thedefault location Docker and Docker Compose clients use to connect tothe Docker daemon, so you can usedockeranddocker-composeCLI commandson your Mac.
This setup is shown in the following diagram.

With Docker Desktop on Mac, you only get (and only usually need) one VM, managed by Docker Desktop. Docker Desktop automatically upgrades the Docker client and daemon when updates are available.
Also note that Docker Desktop can't route traffic to containers, so you can'tdirectly access an exposed port on a running container from the hosting machine.
If you do need multiple VMs, such as when testing multi-node swarms, you cancontinue to use Docker Machine, which operates outside the scope of Docker Desktop. SeeDocker Toolbox and Docker Desktop coexistence.
Setting up to run Docker Desktop on Mac
Check whether Toolbox DOCKER environment variables are set:

If it returns output (as shown in the example), unset the
DOCKERenvironment variables to make the client talk to the Docker Desktop Engine (next step).Run the
unsetcommand on the followingDOCKERenvironment variables tounset them in the current shell.

If it returns output (as shown in the example), unset the
DOCKERenvironment variables to make the client talk to the Docker Desktop Engine (next step).Run the
unsetcommand on the followingDOCKERenvironment variables tounset them in the current shell.
Now, this command should return no output.
If you are using a Bash shell, you can use unset ${!DOCKER_*} to unset all DOCKER environment variables at once. (This does not work in other shells such as zsh; you need to unset each variable individually.)
Note: If you have a shell script as part of your profile that sets theseDOCKER environment variables automatically each time you open a commandwindow, then you need to unset these each time you want to use Docker Desktop. Www google chrome instalar.
If you install Docker Desktop on a machine where Docker Toolbox is installed.
Docker Desktop replaces the docker and docker-compose command lines in/usr/local/bin with symlinks to its own versions.
See also Unset environment variables in the current shellin the Docker Machine topics.
Docker Toolbox and Docker Desktop coexistence
You can use Docker Desktop and Docker Toolbox together on the same machine. Whenyou want to use Docker Desktop make sure all DOCKER environment variables areunset. You can do this in bash with unset ${!DOCKER_*}. When you want to useone of the VirtualBox VMs you have set with docker-machine, just run a eval$(docker-machine env default) (or the name of the machine you want to target).This switches the current command shell to talk to the specified Toolboxmachine.
This setup is represented in the following diagram.
Using different versions of Docker tools
The coexistence setup works as is as long as your VirtualBox VMs provisionedwith docker-machine run the same version of Docker Engine as Docker Desktop.If you need to use VMs running older versions of Docker Engine, you can use atool like Docker Version Manager to manageseveral versions of docker client. Nt wright books pdf.
Checking component versions
Ideally, the Docker CLI client and Docker Engine should be the same version.Mismatches between client and server, and host machines you might havecreated with Docker Machine can cause problems (client can't talk to the serveror host machines).
If you have already installed Docker Toolbox, and theninstalled Docker Desktop, you might get a newer version of the Docker client. Run docker version in a command shell to see client and server versions. In this example, the client installed with Docker Desktop is Version: 19.03.1 and the server (which was installed earlier with Toolbox) is Version: 19.03.2.
Also, if you created machines with Docker Machine (installed with Toolbox) thenupgraded or installed Docker Desktop, you might have machines running differentversions of Engine. Run docker-machine ls to view version information for themachines you created. In this example, the DOCKER column shows that each machineis running a different version of server.
There are a few ways to address this problem and keep using your oldermachines. One solution is to use a version manager likeDVM.
Migrating from Docker Toolbox to Docker Desktop on Mac
Docker Desktop does not propose Toolbox image migration as part of itsinstaller since version 18.01.0. You can migrate existing DockerToolbox images with the steps described below.
In a terminal, while running Toolbox, use docker commit to create an image snapshotfrom a container, for each container you wish to preserve:
Next, export each of these images (and any other images you wish to keep):
Next, when running Docker Desktop on Mac, reload all these images:
Note these steps will not migrate any docker volume contents: these mustbe copied across manually.
Finally (optional), if you are done with Docker Toolbox, you may fullyuninstallit.
