Docker Desktop currently supports macOS Mojave, macOS Catalina, and macOS Big Sur. At least 4 GB of RAM. VirtualBox prior to version 4.3.30 must not be installed as it is not compatible with Docker Desktop.
Jul 12, 2019 macOS Mojave introduces a full dark mode theme, but it also removes the option to use a dark background for just the menu bar and Dock. For those who like the look of a dark menu bar and Dock but find Mojave's full dark mode to be too dark, here's a terminal command that gives you the best of both worlds. 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 these containerized applications on your desktop. Docker-machine create -driver xhyve manager Without VirtualBox. Im using OS X 10.11.6, too. 3: After updating my docker docker-machine command stopper working on my mac terminal. So found after updating my docker I’ll have to reinstall docker-machine CLI just to get the latest version.

Welcome to Docker Desktop! The Docker Desktop for Mac user manual provides information on how to configure and manage your Docker Desktop settings.
For information about Docker Desktop download, system requirements, and installation instructions, see Install Docker Desktop.
The Docker Preferences menu allows you to configure your Docker settings such as installation, updates, version channels, Docker Hub login,and more.
Choose the Docker menu > Preferences from themenu bar and configure the runtime options described below.
On the General tab, you can configure when to start and update Docker:
Automatically check for updates: By default, Docker Desktop is configured to check for newer versions automatically. If you have installed Docker Desktop as part of an organization, you may not be able to update Docker Desktop yourself. In that case, upgrade your existing organization to a Team plan and clear this checkbox to disable the automatic check for updates.
Start Docker Desktop when you log in: Automatically starts Docker Desktop when you open your session.
Include VM in Time Machine backups: Select this option to back up the Docker Desktop virtual machine. This option is disabled by default.
Use gRPC FUSE for file sharing: Clear this checkbox to use the legacy osxfs file sharing instead.
Send usage statistics: Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out.
Show weekly tips: Displays useful advice and suggestions about using Docker.
Open Docker Desktop dashboard at startup: Automatically opens the dashboard when starting Docker Desktop.
Use Docker Compose V2: Select this option to enable the
docker-composecommand to use Docker Compose V2. For more information, see Docker Compose V2.
The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources.
On the Advanced tab, you can limit resources available to Docker.
Advanced settings are:
CPUs: By default, Docker Desktop is set to use half the number of processorsavailable on the host machine. To increase processing power, set this to ahigher number; to decrease, lower the number.
Memory: By default, Docker Desktop is set to use
2GB runtime memory,allocated from the total available memory on your Mac. To increase the 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 image size: Specify the size of the disk image.
Disk image location: Specify the location of the Linux volume where containers and images are stored.
You can also move the disk image to a different location. If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it.
Use File sharing to allow local directories on the Mac to be shared with Linux containers.This is especially useful forediting source code in an IDE on the host while running and testing the code in a container.By default the
/var/folders directory are shared. If your project is outside this directory then it must be addedto the list. Otherwise you may get
Mounts denied 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’sbind mount (
Tips on shared folders, permissions, and volume mounts
Share only the directories that you need with the container. File sharing introduces overhead as any changes to the files on the host need to be notified to the Linux VM. Sharing too many files can lead to high CPU load and slow filesystem performance.
Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume (named volume) or data container.
If you share the whole of your home directory into a container, MacOS may prompt you to give Docker access to personal areas of your home directory such as your Reminders or Downloads.
By default, Mac file systems are case-insensitive while Linux is case-sensitive. On Linux, it is possible to create 2 separate files:
Test, while on Mac these filenames would actually refer to the same underlying file. This can lead to problems where an app works correctly on a Mac (where the file contents are shared) but fails when run in Linux in production (where the file contents are distinct). To avoid this, Docker Desktop insists that all shared files are accessed as their original case. Therefore, if a file is created called
test, it must be opened as
test. Attempts to open
Testwill fail with the error
No such file or directory. Similarly, once a file called
testis created, attempts to create a second file called
Testwill fail. For more information, see Volume mounting requires file sharing for any project directories outside of
Docker Desktop detects HTTP/HTTPS Proxy Settings from macOS and automaticallypropagates these to Docker. For example, if you set yourproxy settings to
http://proxy.example.com, Docker uses this proxy whenpulling containers.
Your proxy settings, however, will not be propagated into the containers you start.If you wish to set the proxy settings for your containers, you need to defineenvironment variables for them, just like you would do on Linux, for example:
For more information on setting environment variables for running containers,see Set environment variables.
You can configure Docker Desktop networking to work on a virtual private network (VPN). Specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity.
The Docker Engine page allows you to configure the Docker daemon to determine how your containers run.
Type a JSON configuration file in the box to configure the daemon settings. For a full list of options, see the Docker Enginedockerd commandline reference.
Click Apply & Restart to save your settings and restart Docker Desktop.
On the Command Line page, you can specify whether or not to enable experimental features.
Experimental features provide early access to future product functionality.These features are intended for testing and feedback only as they may changebetween releases without warning or can be removed entirely from a futurerelease. Experimental features must not be used in production environments.Docker does not offer support for experimental features.
For a list of current experimental features in the Docker CLI, see Docker CLI Experimental features.
You can toggle the experimental features on and off in Docker Desktop. If you toggle the experimental features off, Docker Desktop uses the current generally available release of Docker Engine.
You can see whether you are running experimental mode at the command line. If
true, then Docker is running in experimental mode, as shownhere. (If
false, Experimental mode is off.)

Docker Desktop includes a standalone Kubernetes server that runs on your Mac, sothat you can test deploying your Docker workloads on Kubernetes. To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes.
For more information about using the Kubernetes integration with Docker Desktop, see Deploy on Kubernetes.
Reset and Restart options
On Docker Desktop Mac, the Restart Docker Desktop, Reset to factory defaults, and other reset options are available from the Troubleshoot menu.
For information about the reset options, see Logs and Troubleshooting.
The Software Updates section notifies you of any updates available to Docker Desktop. You can choose to download the update right away, or click the Release Notes option to learn what’s included in the updated version.
If you are on a Docker Team or a Business subscription, you can turn off the check for updates by clearing the Automatically Check for Updates checkbox in the General settings. This will also disable the notification badge that appears on the Docker Dashboard.
The Docker Desktop Dashboard enables you to interact with containers and applications and manage the lifecycle of your applications directly from your machine. The Dashboard UI shows all running, stopped, and started containers with their state. It provides an intuitive interface to perform common actions to inspect and manage containers and existing Docker Compose applications. For more information, see Docker Desktop Dashboard.
Add TLS certificates
You can add trusted Certificate Authorities (CAs) (used to verify registryserver certificates) and client certificates (used to authenticate toregistries) to your Docker daemon.
Add custom CA certificates (server side)
All trusted CAs (root or intermediate) are supported. Docker Desktop creates acertificate bundle of all user-trusted CAs based on the Mac Keychain, andappends it to Moby trusted certificates. So if an enterprise SSL certificate istrusted by the user on the host, it is trusted by Docker Desktop.
To manually add a custom, self-signed certificate, start by adding thecertificate to the macOS keychain, which is picked up by Docker Desktop. Here isan example:
Or, if you prefer to add the certificate to your own local keychain only (ratherthan for all users), run this command instead:
See also, Directory structures forcertificates.
Note: You need to restart Docker Desktop after making any changes to thekeychain or to the
~/.docker/certs.d directory in order for the changes totake effect.
For a complete explanation of how to do this, see the blog post AddingSelf-signed Registry Certs to Docker & Docker Desktop forMac.
Add client certificates
You can put your client certificates in
When the Docker Desktop application starts, it copies the
~/.docker/certs.dfolder on your Mac to the
/etc/docker/certs.d directory on Moby (the DockerDesktop
xhyve virtual machine).
You need to restart Docker Desktop after making any changes to the keychainor to the
~/.docker/certs.ddirectory in order for the changes to takeeffect.
The registry cannot be listed as an insecure registry (see DockerEngine. Docker Desktop ignores certificates listedunder insecure registries, and does not send client certificates. Commandslike
docker runthat attempt to pull from the registry produce errormessages on the command line, as well as on the registry.

Directory structures for certificates
If you have this directory structure, you do not need to manually add the CAcertificate to your Mac OS system login:
The following further illustrates and explains a configuration with customcertificates:
You can also have this directory structure, as long as the CA certificate isalso in your keychain.
To learn more about how to install a CA root certificate for the registry andhow to set the client TLS certificate for verification, seeVerify repository client with certificatesin the Docker Engine topics.
Install shell completion
Docker Desktop comes with scripts to enable completion for the
docker-compose commands. The completion scripts may befound inside
Docker.app, in the
Contents/Resources/etc/ directory and can beinstalled both in Bash and Zsh.
Bash has built-in support forcompletion To activate completion for Docker commands, these files need to becopied or symlinked to your
bash_completion.d/ directory. For example, if youinstalled bash via Homebrew:
Add the following to your
In Zsh, the completionsystemtakes care of things. To activate completion for Docker commands,these files need to be copied or symlinked to your Zsh
site-functions/directory. For example, if you installed Zsh via Homebrew:
Fish-shell also supports tab completion completionsystem. To activate completion for Docker commands,these files need to be copied or symlinked to your Fish-shell
Now add fish completions from docker.
