Docker Desktop creates a certificate bundle of all user-trusted CAs based on the Mac Keychain, and appends it to Moby trusted certificates. So if an enterprise SSL certificate is trusted by the user on the host, it is trusted by Docker Desktop. Docker machine is not running! Run Oracle VM VirtualBox Manager as administrator and make sure “default” machine is “running”. Could not find matching IP. Docker-machine ip default. This proved a convenient way to setup env vars within shell scripts so I could do things like run psql from host and access the postgres container being used by my app. Disclaimer: I realize that docker.local is supposed to be a shortcut way to avoid using IP addresses with Docker for Mac, but for me it currently does. The first step in spoofing your MAC address is to find the network interface device that you want to spoof. Go to StartControl PanelNetwork Connection. Then double click on the device that you want to spoof. Then click on the support tab and then click on details.
You can run Compose on macOS, Windows, and 64-bit Linux.
Docker Compose relies on Docker Engine for any meaningful work, so make sure youhave Docker Engine installed either locally or remote, depending on your setup.
On desktop systems like Docker Desktop for Mac and Windows, Docker Compose isincluded as part of those desktop installs.
On Linux systems, first install theDocker Enginefor your OS as described on the Get Docker page, then come back here forinstructions on installing Compose onLinux systems.
To run Compose as a non-root user, see Manage Docker as a non-root user.
Follow the instructions below to install Compose on Mac, Windows, Windows Server2016, or Linux systems, or find out about alternatives like using the
pipPython package manager or installing Compose as a container.
Install a different version
The instructions below outline installation of the current stable release(v1.28.0) of Compose. To install a different version ofCompose, replace the given release number with the one that you want. Composereleases are also listed and available for direct download on theCompose repository release page on GitHub.To install a pre-release of Compose, refer to the install pre-release buildssection.
Install Compose on macOS
Docker Desktop for Mac includes Compose alongwith other Docker apps, so Mac users do not need to install Compose separately.For installation instructions, see Install Docker Desktop on Mac.
Install Compose on Windows desktop systems
Docker Desktop for Windows includes Composealong with other Docker apps, so most Windows users do not need toinstall Compose separately. For install instructions, see Install Docker Desktop on Windows.
If you are running the Docker daemon and client directly on MicrosoftWindows Server, follow the instructions in the Windows Server tab.
Install Compose on Windows Server
Follow these instructions if you are running the Docker daemon and client directlyon Microsoft Windows Server and want to install Docker Compose.
Start an “elevated” PowerShell (run it as administrator).Search for PowerShell, right-click, and chooseRun as administrator. When asked if you want to allow this appto make changes to your device, click Yes.
In PowerShell, since GitHub now requires TLS1.2, run the following:
Then run the following command to download the current stable release ofCompose (v1.28.0):
Note: On Windows Server 2019, you can add the Compose executable to
$Env:ProgramFilesDocker. Because this directory is registered in the system
PATH, you can run the
docker-compose --version command on the subsequent step with no additional configuration.
Test the installation.
Install Compose on Linux systems
On Linux, you can download the Docker Compose binary from theCompose repository release page on GitHub.Follow the instructions from the link, which involve running the
curl commandin your terminal to download the binaries. These step-by-step instructions arealso included below.
alpine, the following dependency packages are needed:
Run this command to download the current stable release of Docker Compose:
To install a different version of Compose, substitute
1.28.0with the version of Compose you want to use.
If you have problems installing with
curl, seeAlternative Install Options tab above.
Apply executable permissions to the binary:
Note: If the command
docker-compose fails after installation, check your path.You can also create a symbolic link to
/usr/bin or any other directory in your path.
Optionally, install command completion for the
Test the installation.
Alternative install options
Install using pip
alpine, the following dependency packages are needed:
Compose can be installed frompypi using
pip. If you installusing
pip, we recommend that you use avirtualenv because many operatingsystems have python system packages that conflict with docker-composedependencies. See the virtualenvtutorial to getstarted.
If you are not using virtualenv,
pip version 6.0 or greater is required.
Install as a container
Compose can also be run inside a container, from a small bash script wrapper. Toinstall compose as a container run this command:
Install pre-release builds
If you’re interested in trying out a pre-release build, you can download releasecandidates from the Compose repository release page on GitHub.Follow the instructions from the link, which involves running the
curl commandin your terminal to download the binaries.
Pre-releases built from the “master” branch are also available for download athttps://dl.bintray.com/docker-compose/master/.
Pre-release builds allow you to try out new features before they are released,but may be less stable.
If you’re upgrading from Compose 1.2 or earlier, remove ormigrate your existing containers after upgrading Compose. This is because, as ofversion 1.3, Compose uses Docker labels to keep track of containers, and yourcontainers need to be recreated to add the labels.
If Compose detects containers that were created without labels, it refusesto run, so that you don’t end up with two sets of them. If you want to keep usingyour existing containers (for example, because they have data volumes you wantto preserve), you can use Compose 1.5.x to migrate them with the followingcommand:
Alternatively, if you’re not worried about keeping them, you can remove them.Compose just creates new ones.

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:
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.
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.
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
/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.
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
If you installed
kubectl with Homebrew, or by some other method, andexperience conflicts, remove
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/kubectlcommand 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 to
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/kubectlcommand 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.
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
Dockermachine Error Could Not Find Matching Ip For Mac High Sierra
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
