Reset to factory defaults: Choose this option to reset all options onDocker Desktop to their initial state, the same as when Docker Desktop was first installed.
Uninstall: Choose this option to remove Docker Desktop from yoursystem.
Uninstall Docker Desktop from the command line
To uninstall Docker Desktop from a terminal, run: <DockerforMacPath>--uninstall. If your instance is installed in the default location, thiscommand provides a clean uninstall:
You might want to use the command-line uninstall if, for example, you find thatthe app is non-functional, and you cannot uninstall it from the menu.
If you encounter problems for which you do not find solutions in thisdocumentation, on Docker Desktop issues onGitHub, or the Docker Desktop forum, we can help you troubleshootthe log data.
Choose > Troubleshoot > Run Diagnostics.
Once the diagnostics are available, you can upload them and obtain aDiagnostic ID, which must be provided when communicating with the Dockerteam. For more information on our policy regarding personal data, seehow is personal data handled in Docker Desktop.
If you click Report an issue, this opens Docker Desktop for Mac issues on GitHub in your web browser in a “New issue” template. Add the details before submitting the issue. Do not forget to copy/paste your diagnostic ID.
In some cases, it is useful to run the diagnostics yourself, for instance, ifDocker Desktop cannot start.
First, locate the com.docker.diagnose tool. If you have installed Docker Desktop in the Applications directory, then it is located at/Applications/Docker.app/Contents/MacOS/com.docker.diagnose.
To create and upload diagnostics, run:
After the diagnostics have finished, you should have the following output,containing your diagnostics ID:
The diagnostics ID (here BE9AFAAF-F68B-41D0-9D12-84760E6B8740/20190905152051) iscomposed of your user ID (BE9AFAAF-F68B-41D0-9D12-84760E6B8740) and a timestamp(20190905152051). Ensure you provide the full diagnostics ID, and not just the user ID.
To view the contents of the diagnostic file, run:
In addition to using the diagnose and feedback option to submit logs, you canbrowse the logs yourself. The following documentation is about macOS 10.12onwards; for older versions, seeolder documentation.
To watch the live flow of Docker Desktop logs in the command line, run the following script from your favorite shell.
Alternatively, to collect the last day of logs (1d) in a file, run:

Macs provide a built-in log viewer, named “Console”, which you can use to checkDocker logs.
The Console lives in /Applications/Utilities; you can search for it withSpotlight Search.
To read the Docker app log messages, type docker in the Console window search bar and press Enter. Then select ANY to expand the drop-down list next to your docker search entry, and select Process.
You can use the Console Log Query to search logs, filter the results in variousways, and create reports.
Docker Desktop ignores certificates listed under insecure registries, and doesnot send client certificates to them. Commands like docker run that attempt topull from the registry produces error messages on the command line, for example:
As well as on the registry. For example:
For more about using client and server side certificates, seeAdding TLS certificates in the Getting Started topic.
SeeDo I need to reinstall Docker Desktop if I change the name of my macOS account?in the FAQs.
/UsersIf you are using mounted volumes and get runtime errors indicating anapplication file is not found, access to a volume mount is denied, or a servicecannot start, such as when using Docker Compose,you might need to enable file sharing.
Volume mounting requires shared drives for projects that live outside of the/Users directory. Go to >Preferences > Resources > File sharing and share the drive that contains the Dockerfile and volume.
Docker Desktop requires a processor (CPU) that supports virtualization and, morespecifically, the Apple Hypervisorframework.Docker Desktop is only compatible with Mac systems that have a CPU that supports the Hypervisor framework. Most Macs built in 2010 and later support it,as described in the Apple Hypervisor Framework documentation about supported hardware:
Generally, machines with an Intel VT-x feature set that includes Extended PageTables (EPT) and Unrestricted Mode are supported.
To check if your Mac supports the Hypervisor framework, run the following command in a terminal window.
If your Mac supports the Hypervisor Framework, the command printskern.hv_support: 1.
If not, the command prints kern.hv_support: 0.
See also, Hypervisor FrameworkReferencein the Apple documentation, and Docker Desktop Mac system requirements.
If Docker Desktop fails to install or start properly on Mac:
Make sure you quit Docker Desktop before installing a new version of theapplication ( > Quit Docker Desktop). Otherwise, you get an “application in use” error when you try tocopy the new app from the .dmg to /Applications.
Restart your Mac to stop / discard any vestige of the daemon running fromthe previously installed version.
Run the uninstall commands from the menu.
If docker commands aren’t working properly or as expected, you may need tounset some environment variables, to make sure you are not using the legacyDocker Machine environment in your shell or command window. Unset theDOCKER_HOST environment variable and related variables.
If you use bash, use the following command: unset ${!DOCKER_*}
For other shells, unset each environment variable individually as describedin Setting up to run Docker Desktop on Macin Docker Desktop on Mac vs. Docker Toolbox.
Network connections fail if the macOS Firewall is set to “Block all incomingconnections”. You can enable the firewall, but bootpd must be allowedincoming connections so that the VM can get an IP address.
For the hello-world-nginx example, Docker Desktop must be running to get tothe web server on http://localhost/. Make sure that the Docker icon isdisplayed on the menu bar, and that you run the Docker commands in a shell that is connected to the Docker Desktop Engine (not Engine from Toolbox).Otherwise, you might start the webserver container but get a “web page notavailable” error when you go to localhost. For more information on distinguishing between the two environments, see Docker Desktop on Mac vs. Docker Toolbox.
If you see errors like Bind for 0.0.0.0:8080 failed: port is alreadyallocated or listen tcp:0.0.0.0:8080: bind: address is already in use:
These errors are often caused by some other software on the Mac using thoseports.
Run lsof -i tcp:8080 to discover the name and pid of the other process anddecide whether to shut the other process down, or to use a different port inyour docker app.
IPv6 is not (yet) supported on Docker Desktop.
You might encounter errors when using docker-compose up with Docker Desktop(ValueError: Extra Data). We’ve identified this is likely related to dataand/or events being passed all at once rather than one by one, so sometimesthe data comes back as 2+ objects concatenated and causes an error.
Force-ejecting the .dmg after running Docker.app from it can cause thewhale icon to become unresponsive, Docker tasks to show as not responding inthe Activity Monitor, and for some processes to consume a large amount of CPUresources. Reboot and restart Docker to resolve these issues.
Docker does not auto-start on login even when it is enabled in > Preferences. This is related to aset of issues with Docker helper, registration, and versioning.
Docker Desktop uses the HyperKit hypervisor(https://github.com/docker/hyperkit) in macOS 10.10 Yosemite and higher. Ifyou are developing with tools that have conflicts with HyperKit, such asIntel Hardware Accelerated Execution Manager(HAXM),the current workaround is not to run them at the same time. You can pauseHyperKit by quitting Docker Desktop temporarily while you work with HAXM.This allows you to continue work with the other tools and prevent HyperKitfrom interfering.
If you are working with applications like ApacheMaven that expect settings for DOCKER_HOST andDOCKER_CERT_PATH environment variables, specify these to connect to Dockerinstances through Unix sockets. For example:
docker-compose 1.7.1 performs DNS unnecessary lookups forlocalunixsocket.local which can take 5s to timeout on some networks. Ifdocker-compose commands seem very slow but seem to speed up when the networkis disabled, try appending 127.0.0.1 localunixsocket.local to the file/etc/hosts. Alternatively you could create a plain-text TCP proxy onlocalhost:1234 using:
and then export DOCKER_HOST=tcp://localhost:1234.
There are a number of issues with the performance of directories bind-mountedwith osxfs. In particular, writes of small blocks, and traversals of largedirectories are currently slow. Additionally, containers that perform largenumbers of directory operations, such as repeated scans of large directorytrees, may suffer from poor performance. Applications that behave in this wayinclude:
rakeember buildvendor folderAs a work-around for this behavior, you can put vendor or third-party librarydirectories in Docker volumes, perform temporary file system operationsoutside of osxfs mounts, and use third-party tools like Unison or rsync tosynchronize between container directories and bind-mounted directories. We areactively working on osxfs performance using a number of differenttechniques. To learn more, see the topic onPerformance issues, solutions, and roadmap.
If your system does not have access to an NTP server, then after a hibernatethe time seen by Docker Desktop may be considerably out of sync with the host.Furthermore, the time may slowly drift out of sync during use. To manuallyreset the time after hibernation, run:
Or, to resolve both issues, you can add the local clock as a low-priority(high stratum) fallback NTP time source for the host. To do this, edit thehost’s /etc/ntp-restrict.conf to add:
Then restart the NTP service with:
Welcome to Docker Desktop!
The Docker Desktop for Mac section contains information about the Docker Desktop Community Stable release. For information about features available in Edge releases, see the Edge release notes. For information about Docker Desktop Enterprise (DDE) releases, see Docker Desktop Enterprise.
Docker is a full development platform to build, run, and share containerized applications. Docker Desktop is the best way to get started with Docker on Mac.
See Install Docker Desktop for download information, system requirements, and installation instructions.
Ensure your versions of docker and docker-compose areup-to-date and compatible with Docker.app. Your output may differ if you arerunning different versions.
Open a command-line terminal and test that your installation works byrunning the simple Docker image,hello-world:
Start a Dockerized web server. Like the hello-world image above, if theimage is not found locally, Docker pulls it from Docker Hub.
In a web browser, go to http://localhost/ 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
dockeras the hostname to build the URL. Now,ports are exposed on the private IP addresses of the VM and forwarded tolocalhostwith no other host name set.
View the details on the container while your web server is running (withdocker container ls or docker ps):
Stop and remove containers and images with the following commands. Use the“all” flag (--all or -a) to view stopped containers.
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:
Start Docker Desktop when you log in: Automatically starts Docker Desktop when you open your session.
Automatically check for updates: By default, Docker Desktop automatically checks for updates and notifies you when an update is available. You can manually check for updates anytime by choosing Check for Updates from the main Docker menu.
Include VM in Time Machine backups: Select this option to back up the Docker Desktop virtual machine. This option is disabled by default.
Securely store Docker logins in macOS keychain: Docker Desktop stores your Docker login credentials in macOS keychain by default.
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.
Click Switch to the Edge version to learn more about Docker Desktop Edge releases.
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 2 GB 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 /Users, /Volume, /private, /tmp and /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 (-v) feature.
There are some limitations on the directories that can be shared:
For more information, see:
/Users.)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.
To enable experimental features in the Docker CLI, edit the config.jsonfile and set experimental to enabled.
To enable experimental features from the Docker Desktop menu, clickSettings (Preferences on macOS) > Command Line and then turn onthe Enable experimental features toggle. Click Apply & Restart.
For a list of current experimental features in the Docker CLI, see Docker CLI Experimental features.
On both Docker Desktop Edge and Stable releases, you can toggle the experimental features on and off. 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. IfExperimental is 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.
The Kubernetes client command, kubectl, is included and configured to connectto the local Kubernetes server. If you have kubectl already installed andpointing to some other environment, such as minikube or a GKE cluster, be sureto change context so that kubectl is pointing to docker-desktop:
If you installed kubectl with Homebrew, or by some other method, andexperience conflicts, remove /usr/local/bin/kubectl.
To enable Kubernetes support and install a standalone instance of Kubernetesrunning as a Docker container, select Enable Kubernetes. To set Kubernetes as thedefault orchestrator, select Deploy Docker Stacks to Kubernetes by default.
Click Apply & Restart to save the settings. This instantiates images required to run the Kubernetes server as containers, and installs the/usr/local/bin/kubectl command on your Mac.
When Kubernetes is enabled and running, an additional status bar item displaysat the bottom right of the Docker Desktop Settings dialog.
The status of Kubernetes shows in the Docker menu and the context points todocker-desktop.
By default, Kubernetes containers are hidden from commands like dockerservice ls, because managing them manually is not supported. To make themvisible, select Show system containers (advanced) and click Apply andRestart. Most users do not need this option.
To disable Kubernetes support at any time, clear the Enable Kubernetes check box. TheKubernetes containers are stopped and removed, and the/usr/local/bin/kubectl command is removed.
For more about using the Kubernetes integration with Docker Desktop, seeDeploy 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 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.
You can add trusted Certificate Authorities (CAs) (used to verify registryserver certificates) and client certificates (used to authenticate toregistries) to your Docker daemon.
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.
You can put your client certificates in~/.docker/certs.d/<MyRegistry>:<Port>/client.cert and~/.docker/certs.d/<MyRegistry>:<Port>/client.key.
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.d directory 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 run that attempt to pull from the registry produce errormessages on the command line, as well as on the registry.
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.
Docker Desktop comes with scripts to enable completion for the docker and docker-compose commands. Onedrive for mac el capitan. 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 ~/.bash_profile:
OR
In Zsh, the completionsystem takes 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 completions/directory.
Create the completions directory:
Now add fish completions from docker.
