Thanks for the heads-up: brew cask install docker && brew install bash-completion docker-completion docker-compose-completion docker-machine-completion – mimoralea Dec 6 '18 at 16:49 Don't use docker-machine - it will gives you a lot of headache with network forwarding – Vlad Jan 7 '19 at 20:40. May 11, 2020 Both the docker engine and a recent version of docker-compose are installed when you install Docker for Mac from the package. Once you have Docker for Mac installed, open up the preferences pane for Docker, go to the 'Resources' section and increase the allocated memory to 6GB. See full list on runnable.com.

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.

Note

This page contains information about the Docker Desktop Stable release. For information about features available in Edge releases, see the Edge release notes.

Preferences

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.

General

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.

Resources

The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources.

Advanced

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.

File sharing

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:

  • The directory must not exist inside of Docker.

For more information, see:

• Namespaces in the topic onosxfs file system sharing.
• Volume mounting requires file sharing for any project directories outside of /Users.)

Proxies

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.

Network

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.

Docker Engine

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.

Command Line

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.)

Kubernetes

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

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.

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~/.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.

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 and 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

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

Zsh

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

Install Docker For Mac

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.

The Docker Dashboard provides a simple interface that enables you to manage your containers, applications, and images directly from your machine without having to use the CLI to perform core actions.

The Containers/Apps view provides a runtime view of all your containers and applications. It allows you to interact with containers and applications, and manage the lifecycle of your applications directly from your machine. This view also provides an intuitive interface to perform common actions to inspect, interact with, and manage your Docker objects including containers and Docker Compose-based applications.

The Images view displays a list of your Docker images, and allows you to run an image as a container, pull the latest version of an image from Docker Hub, and inspect images. It also contains clean up options to remove unwanted images from the disk to reclaim space. If you are logged in, you can also see the images you and your organization have shared on Docker Hub.

In addition, the Docker Dashboard allows you to:

• Easily navigate to the Preferences (Settings in Windows) menu to configure Docker Desktop preferences
• Access the Troubleshoot menu to debug and perform restart operations
• Sign into Docker Hub using your Docker ID

To access the Docker Dashboard, from the Docker menu, select Dashboard. On Windows, click the Docker icon to open the Dashboard.

Explore running containers and applications

From the Docker menu, select Dashboard. This lists all your running containers and applications. You must have running or stopped containers and applications to see them listed on the Docker Dashboard.

The following sections guide you through the process of creating a sample Redis container and a sample application to demonstrate the core functionalities in Docker Dashboard.

Docker Compose Install For Mac Os

Start a Redis container

To start a Redis container, open your preferred CLI and run the following command:

docker run -dt redis

This creates a new Redis container. From the Docker menu, select Dashboard to see the new Redis container.

Start a sample application

Let’s start a sample application. Download the Example voting app from the Docker samples page. The example voting app is a distributed application that runs across multiple Docker containers. The app contains:

• A front-end web app in Python or ASP.NET Core which lets you vote between two options
• A Redis or NATS queue which collects new votes
• A .NET Core, Java or .NET Core 2.1 worker which consumes votes and stores them
• A Postgres or TiDB database backed by a Docker volume
• A Node.js or ASP.NET Core SignalR web app which shows the results of the voting in real time

To start the application, navigate to the directory containing the example voting application in the CLI and run docker-compose up --build.

When the application starts successfully, from the Docker menu, select Dashboard to see the Example voting application. Expand the application to see the containers running inside the application.

Now that you can see the list of running containers and applications on the Dashboard, let us explore some of the actions you can perform:

Docker Compose Install For Mac Windows 10

• Click Port to open the port exposed by the container in a browser.
• Click CLI to open a terminal and run commands on the container.
• Click Stop, Start, Restart, or Delete to perform lifecycle operations on the container.

Use the Search option to search for a specific object. You can also sort your containers and applications using various options. Click the Sort by drop-down to see a list of available options.

Interact with containers and applications

From the Docker Dashboard, select the example voting application we started earlier.

The Containers/Apps view lists all the containers running on the application and contains a detailed logs view. It also allows you to start, stop, or delete the application. Use the Search option at the bottom of the logs view to search application logs for specific events, or select the Copy icon to copy the logs to your clipboard.

Click Open in Visual Studio Code to open the application to open the application in VS Code. Hover over the list of containers to see some of the core actions you can perform.

Container view

Click on a specific container for detailed information about the container. The container view displays Logs, Inspect, and Stats tabs and provides quick action buttons to perform various actions.

• Select Logs to see logs from the container. You can also search the logs for specific events and copy the logs to your clipboard.

• Select Inspect to view low-level information about the container. You can see the local path, version number of the image, SHA-256, port mapping, and other details.

• Select Stats to view information about the container resource utilization. You can see the amount of CPU, disk I/O, memory, and network I/O used by the container.

You can also use the quick action buttons on the top bar to perform common actions such as opening a CLI to run commands in a container, and perform lifecycle operations such as stop, start, restart, or delete your container.

Explore your images

The Images view is a simple interface that lets you manage Docker images without having to use the CLI. By default, it displays a list of all Docker images on your local disk. To view images in remote repositories, click Sign in and connect to Docker Hub. This allows you to collaborate with your team and manage your images directly through Docker Desktop.

The Images view allows you to perform core operations such as running an image as a container, pulling the latest version of an image from Docker Hub, pushing the image to Docker Hub, and inspecting images.

In addition, the Images view displays metadata about the image such as the tag, image ID, date when the image was created, and the size of the image. It also displays In Use tags next to images used by running and stopped containers. This allows you to review the list of images and use the Clean up images option to remove any unwanted images from the disk to reclaim space.

The Images view also allows you to search images on your local disk and sort them using various options.

Let’s explore the various options in the Images view.

If you don’t have any images on your disk, run the command docker pull redis in a terminal to pull the latest Redis image. This command pulls the latest Redis image from Docker Hub.

Select Dashboard > Images to see the Redis image.

Run an image as a container

Now that you have a Redis image on your disk, let’s run this image as a container:

1. From the Docker menu, select Dashboard > Images. This displays a list of images on your local disk.
2. Select the Redis image from the list and click Run.

3. When prompted, click the Optional settings drop-down to specify a name, port, volumes, and click Run.

   To use the defaults, click Run without specifying any optional settings. This creates a new container from the Redis image and opens it on the Container/Apps view.

Pull the latest image from Docker Hub

To pull the latest image from Docker Hub:

1. From the Docker menu, select Dashboard > Images. This displays a list of images on your local disk.
2. Select the image from the list and click the more options button.
3. Click Pull. This pulls the latest version of the image from Docker Hub.

Note

The repository must exist on Docker Hub in order to pull the latest version of an image. You must be logged in to pull private images.

Push an image to Docker Hub

To push an image to Docker Hub:

1. From the Docker menu, select Dashboard > Images. This displays a list of images on your local disk.
2. Select the image from the list and click the more options button.
3. Click Push to Hub.

Note

You can only push an image to Docker Hub if the image belongs to your Docker ID or your organization. That is, the image must contain the correct username/organization in its tag to be able to push it to Docker Hub.

Inspect an image

Inspecting an image displays detailed information about the image such as the image history, image ID, the date the image was created, size of the image, etc. To inspect an image:

1. From the Docker menu, select Dashboard > Images. This displays a list of images on your local disk.
2. Select the image from the list and click the more options button.
3. Click Inspect.
4. The image inspect view also provides options to pull the latest image, push image to Hub, remove the image, or run the image as a container.

Remove an image

The Images view allows you to remove unwanted images from the disk. The Images on disk status bar displays the number of images and the total disk space used by the images.

You can remove individual images or use the Clean up option to delete unused and dangling images.

To remove individual images:

1. From the Docker menu, select Dashboard > Images. This displays a list of images on your local disk.
2. Select the image from the list and click the more options button.
3. Click Remove. This removes the image from your disk.

Note

To remove an image used by a running or a stopped container, you must first remove the associated container.

To remove unused and dangling images:

An unused image is an image which is not used by any running or stopped containers. An image becomes dangling when you build a new version of the image with the same tag.

To remove an unused or a dangling image:

1. From the Docker menu, select Dashboard > Images. This displays a list of images on your disk.
2. Select the Clean up option from the Images on disk status bar.

3. Use the Unused and Dangling check boxes to select the type of images you would like to remove.

   The Clean up images status bar displays the total space you can reclaim by removing the selected images.

4. Click Remove to confirm.

Interact with remote repositories

The Images view also allows you to manage and interact with images in remote repositories and lets you switch between organizations.

The Pull option allows you to pull the latest version of the image from Docker Hub. The View in Hub option opens the Docker Hub page and displays detailed information about the image, such as the OS architecture, size of the image, the date when the image was pushed, and a list of the image layers.

Install Docker On Mac Os

To interact with remote repositories:

1. Click the Remote repositories tab.
2. Select an organization from the drop-down list. This displays a list of repositories in your organization.
3. Click on an image from the list and then select Pull to pull the latest image from the remote repository.
