Personally I Found That Docker For Mac

Apr 14, 2015  In this Docker tutorial for beginners, we're going to be running our first Docker container in production. You'll get to see just how fast, easy, and STABLE it is to use Docker for deploying your. I'm personally more used to macos as I have been an app developer prior. I found that Mac Docker uses at least 2gb of RAM and about 10% CPU.

Docker Desktop for Mac is the Community version of Docker for Mac.You can download Docker Desktop for Mac from Docker Hub.

By downloading Docker Desktop, you agree to the terms of the Docker Software End User License Agreement and the Docker Data Processing Agreement.

What to know before you install

README FIRST for Docker Toolbox and Docker Machine users

If you are already running Docker on your machine, first readDocker Desktop for Mac vs. Docker Toolbox to understand theimpact of this installation on your existing setup, how to set your environmentfor Docker Desktop on Mac, and how the two products can coexist.

Relationship to Docker Machine: Installing Docker Desktop on Mac does not affect machines you created with Docker Machine. You have the option to copy containers and images from your local default machine (if one exists) to the Docker Desktop HyperKit VM. Whenyou are running Docker Desktop, you do not need Docker Machine nodes running locally (or anywhere else). With Docker Desktop, you have a new, nativevirtualization system running (HyperKit) which takes the place of theVirtualBox system. To learn more, see Docker Desktop for Mac vs. Docker Toolbox.

System requirements

Your Mac must meet the following requirements to successfully install Docker Desktop:

• Mac hardware must be a 2010 or a newer model, with Intel’s hardware support for memory management unit (MMU) virtualization, including Extended Page Tables (EPT) and Unrestricted Mode. You can check to see if your machine has this support by running the following command in a terminal: sysctl kern.hv_support

  If your Mac supports the Hypervisor framework, the command prints kern.hv_support: 1.

• macOS must be version 10.13 or newer. That is, Catalina, Mojave, or High Sierra. We recommend upgrading to the latest version of macOS.

  If you experience any issues after upgrading your macOS to version 10.15, you must install the latest version of Docker Desktop to be compatible with this version of macOS.

  Note: Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. Docker Desktop currently supports macOS Catalina, macOS Mojave, and macOS High Sierra.

  As new major versions of macOS are made generally available, Docker stops supporting the oldest version and support the newest version of macOS (in addition to the previous two releases).

• 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.

What’s included in the installer

The Docker Desktop installation includes Docker Engine, Docker CLI client, Docker Compose, Notary, Kubernetes, and Credential Helper.

Install and run Docker Desktop on Mac

1. Double-click Docker.dmg to open the installer, then drag the Docker icon to the Applications folder.

2. Double-click Docker.app in the Applications folder to start Docker. (In the example below, the Applications folder is in “grid” view mode.)

   You are prompted to authorize Docker.app with your system password after you launch it. Privileged access is needed to install networking components and links to the Docker apps.

   The Docker menu in the top status bar indicates that Docker Desktop is running, and accessible from a terminal.

   If you just installed the app, you also get a message with suggested next steps and a link to the documentation. Click the Docker menu () in the status bar to dismiss this pop-up notification.

3. Click the Docker menu () to seePreferences and other options.

4. Select About Docker to verify that you have the latest version.

Congratulations! You are now successfully running Docker Desktop.

Viewing netlist on native ltspice for mac pro. Click the Download for Mac OS X 10.7+ button within the Download LTspice section of the homepage to download the LTspice.dmg file. Download LTspice Section Of LTspice Homepage Double-click the downloaded dmg file to mount the volume. Is there anyone else that has been using LTSpice for MAC? There seems to be some menus missing or at least hard to find. I use an iMac at home and I am glad there are some programs porting over: LTSpice and Eagle. Has anyone else tried LTSpice for the Mac. Your thoughts on the interface? This website gives instuctions to 'select menu “View” and then select “SPICE Netlist”' to view the netlist of the schematic. However, as can be seen in the below screenshot, I have no option for 'View' since it seems that the LTspice mac version has been pared down. Any advice on how to remedy this would be awesome.

Uninstall Docker Desktop

To unistall Docker Desktop from your Mac:

1. From the Docker menu, select Troubleshoot and then select Uninstall.
2. Click Uninstall to confirm your selection.

Note: Uninstalling Docker Desktop will destroy Docker containers and images local to the machine and remove the files generated by the application.

Switch between Stable and Edge versions

Docker Desktop allows you to switch between Stable and Edge releases. However, you can only have one version of Docker Desktop installed at a time. Switching between Stable and Edge versions can destabilize your development environment, particularly in cases where you switch from a newer (Edge) channel to an older (Stable) channel.

For example, containers created with a newer Edge version of Docker Desktop maynot work after you switch back to Stable because they may have been createdusing Edge features that aren’t in Stable yet. Keep this in mind asyou create and work with Edge containers, perhaps in the spirit of a playgroundspace where you are prepared to troubleshoot or start over.

To safely switch between Edge and Stable versions, ensure you save images and export the containers you need, then uninstall the current version before installing another. For more information, see the section Save and Restore data below.

Save and restore data

You can use the following procedure to save and restore images and container data. For example, if you want to switch between Edge and Stable, or to reset your VM disk:

1. Use docker save -o images.tar image1 [image2 ..] to save any images you want to keep. See save in the Docker Engine command line reference.

2. Use docker export -o myContainner1.tar container1 Change download folder on mac. to export containers you want to keep. See export in the Docker Engine command line reference.

3. Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk.

4. Use docker load -i images.tar to reload previously saved images. See load in the Docker Engine.

5. Use docker import -i myContainer1.tar to create a filesystem image corresponding to the previously exported containers. See import in the Docker Engine.

For information on how to back up and restore data volumes, see Backup, restore, or migrate data volumes.

Stable and Edge releases

How do I get the Stable or the Edge version of Docker Desktop?

You can download the Stable or the Edge version of Docker Desktop from Docker Hub.

For installation instructions, see Install Docker Desktop on Mac.

What is the difference between the Stable and Edge versions of Docker Desktop?

Two different download channels are available in the Community version of Docker Desktop:

The Stable channel provides a general availability release-ready installer for a fully baked and tested, more reliable app. The Stable version of Docker Desktop comes with the latest released version of Docker Engine. The releaseschedule is synched with Docker Engine releases and patch releases. On the Stable channel, you can select whether to send usage statistics and other data.

The Edge channel provides an installer with new features we are working on, but is not necessarily fully tested. It comes with the experimental version of Docker Engine. Bugs, crashes, and issues are more likely to occur with the Edge version, but you get a chance to preview new functionality, experiment, and provide feedback as the apps evolve. Releases are typically more frequent than for Stable, often one or more per month. Usage statistics and crash reports are sent by default. You do not have the option to disable this on the Edge channel.

Can I switch between Stable and Edge versions of Docker Desktop?

Yes, you can switch between Stable and Edge versions. You can try out the Edge releases to see what’s new, then go back to Stable for other work. However, you can only have one version of Docker Desktop installed at a time. For more information, see Switch between Stable and Edge versions.

What is Docker.app?

Docker.app is Docker Desktop on Mac. It bundles the Docker client and Docker Engine. Docker.app uses the macOS Hypervisor.framework to run containers, which means that a separate VirtualBox is not required to run Docker Desktop.

What are the system requirements for Docker Desktop?

You need a Mac that supports hardware virtualization. For more information, see Docker Desktop Mac system requirements.

What is an experimental feature?

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.

How do I?

How do I connect to the remote Docker Engine API?

You might need to provide the location of the Engine API for Docker clients anddevelopment tools.

On Docker Desktop, clients can connect to the Docker Engine through a Unixsocket: unix:///var/run/docker.sock.

See also Docker Engine API and Docker Desktop for Mac forums topicUsing pycharm Docker plugin..

If you are working with applications like Apache Maventhat expect settings for DOCKER_HOST and DOCKER_CERT_PATH environmentvariables, specify these to connect to Docker instances through Unix sockets.For example:

How do I connect from a container to a service on the host?

Mac has a changing IP address (or none if you have no network access). We recommend that you attach an unused IP to the lo0 interface on theMac so that containers can connect to this address.

For more information and examples, seeI want to connect from a container to a service on the host in the Networking topic.

How do I connect to a container from Mac?

We recommend that you publish a port, or connect from another container. You can use the same method on Linux if the container is on an overlay network and not a bridge network, as these are not routed.

For more information and examples, seeI want to connect to a container from the Mac in the Networking topic.

Can I use an SSH agent inside a container?

Yes, you can use the host’s SSH agent inside a container. For more information, see SSH agent forwarding.

How do I add custom CA certificates?

Docker Desktop supports all trusted certificate authorities (CAs) (root or intermediate). For more information on adding server and client side certs, seeAdd TLS certificates in the Getting Started topic.

How do I add client certificates?

For information on adding client certificates, seeAdd client certificates in the Getting Started topic.

Can I pass through a USB device to a container?

Unfortunately, it is not possible to pass through a USB device (or aserial port) to a container as it requires support at the hypervisor level.

Can I run Docker Desktop in nested virtualization scenarios?

Docker Desktop can run inside a Windows 10 VM running on apps like Parallels or VMware Fusion on a Mac provided that the VM is properly configured. However, problems and intermittent failures may still occur due to the way these apps virtualize the hardware. For these reasons, Docker Desktop is not supported in nested virtualization scenarios. It might work in some cases, and not in others. For more information, see Running Docker Desktop in nested virtualization scenarios.

Components of Docker Desktop

What is HyperKit?

HyperKit is a hypervisor built on top of the Hypervisor.framework in macOS. It runs entirely in userspace and has no otherdependencies.

We use HyperKit to eliminate the need for other VM products, such as OracleVirtualBox or VMWare Fusion.

What is the benefit of HyperKit?

HyperKit is thinner than VirtualBox and VMWare fusion, and the version we include is customized for Docker workloads on Mac.

Why is com.docker.vmnetd running after I quit the app?

The privileged helper process com.docker.vmnetd is started by launchd andruns in the background. The process does not consume any resources unlessDocker.app connects to it, so it’s safe to ignore.

Feedback

What kind of feedback are we looking for?

Everything is fair game. We’d like your impressions on the download-installprocess, startup, functionality available, the GUI, usefulness of the app,command line integration, and so on. Tell us about problems, what you like, orfunctionality you’d like to see added.

What if I have problems or questions?

You can find information about diagnosing and troubleshooting common issues in the Logs and Troubleshooting topic.

If you do not find a solution in Troubleshooting, browse issues onDocker Desktop for Mac issues on GitHub or create a new one. You can also create new issues based on diagnostics. To learn more, seeDiagnose problems, send feedback, and create GitHub issues.

The Docker Desktop for Mac forumprovides discussion threads as well, and you can create discussion topics there,but we recommend using the GitHub issues over the forums for better tracking andresponse.

How can I opt out of sending my usage data?

If you do not want to send of usage data, use the Stable channel. For moreinformation, see What is the difference between the Stable and Edge versions of Docker Desktop.

How is personal data handled in Docker Desktop?

When uploading diagnostics to help Docker with investigating issues, theuploaded diagnostics bundle may contain personal data such as usernames and IPaddresses. The diagnostics bundles are only accessible to Docker, Inc. employeeswho are directly involved in diagnosing Docker Desktop issues.

By default Docker, Inc. will delete uploaded diagnostics bundles after 30 days unless they are referenced in an open issue on thedocker/for-mac ordocker/for-win issue trackers. If anissue is closed, Docker, Inc. will remove the referenced diagnostics bundleswithin 30 days. You may also request the removal of a diagnostics bundle byeither specifying the diagnostics ID or via your GitHub ID (if the diagnosticsID is mentioned in a GitHub issue). Docker, Inc. will only use the data in thediagnostics bundle to investigate specific user issues, but may derive high-level (non personal) metrics such as the rate of issues from it.
