Hearty Mask Mac OS

Estimated reading time: 15 minutes

Welcome to Docker Desktop! The Docker Desktop for Mac user manual provides information on how to configure and manage your Docker Desktop settings.

Actually worked fine on the Virtual Game Station emulator for Mac OS 9 (wish they would make a new OS X version.) I have the original Innocent Sin CD, burned the ISO with Alcohol 120 at 4x. Any help would be appreciated. I’m currently playing it on my old Mac laptop with no problem but would really like to play it on real hardware. The app interface is designed to be more familiar to Mac users, with the translucent sidebar and smaller items ready for the mouse pointer. But what’s most impressive is that the concept is not. I need to retrieve the default gateway on a Mac machine. I know that in Linux route -n will give an output from which I can easily retrieve this information. However this is not working in Mac OSX(Snow Leopard). I also tried netstat -nr grep 'default', but I was hoping for a cleaner output like that produced by route -n in Linux/Unix.

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:

  • 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.

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.

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 and 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 Test will fail with the error No such file or directory. Similarly, once a file called test is created, attempts to create a second file called Test will fail. For more information, see 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.

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. IfExperimental is true, then Docker is running in experimental mode, as shownhere. (If false, Experimental mode is off.)

Kubernetes

Mac

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

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.

Hearty Mask Mac Os Download

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 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

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.

You can not insert the heart symbols?

Please consider that you have to press the numbers on the numeric keypad of your keyboard. Meanwhile remains down the [Alt] key. With a laptop you take the additional [Fn] key for help. For example: [Alt] + permanently [Fn] + durable combination. For a desktop computer, pressing the so-called [Fn] n button.

Paste on Linux, Mac and Windows

For you to put your heart with little effort in each document. Do you use a PC with Windows 7 or lower, you have to click on and then select “All Programs” Windows icon. Click on “Accessories> System Tools> Character Map” button. There you’ll find the heart symbol in different fonts. You can simply copy and paste with the keyboard shortcut CTRL + V in the desired document. Alternatively, it can also be entered with a right click and “Paste”. Do you use Windows 8, you must only use the Windows search for the term search “Character”. Then the desired icon is selected and can be easily inserted into the document. Mac also provides the ability to insert a heart sign. This works in all Mac-internal programs by clicking “Edit” and then “special characters” callest. Under “Different characters” you can find the heart and can use it directly by clicking on “Install”. The principle works even for all major browsers. In the end, the heart symbol with both Windows and Mac are easily entered. Even users of Linux operating system will find the characters in the character table and it can thus insert in documents or chats.

How do I make a heart symbol in Facebook, Skype and Twitter?

Facebook: Easily insert in Chat & History

This is how you make a heart symbol on Facebook: In Facebook the same are two different ways to represent the heart sign. It can be both a pink heart and a small red heart be included on a white, highlighted underground. The Pink Heart created one, in which one in the box, the two special characters “less-than” and “3” in succession type “<3”. Facebook automatically converts this key combination then in a pink heart around, so in the end only one heart and not special characters can be seen. For the smaller, red heart you open the Windows Start menu and select Programs “Character” from. Lets you attach a variety of special characters, see. Under the writing “Arial” is shown in the bottom third of the list a black heart (♥). This can be clicked and copied at the bottom menu list. In the status box of Facebook it can be finally via right-click Insert. Done. While posting the heart is then converted to a red heart. If, however, remain the black heart, so you can directly bypass the automatic conversion with a special character such as a period, comma or colon after the characters.

Skype: Several options and functions

Similar to Facebook is true for the Messenger service Skype. Use the key combination (l), the “L” for “love” is, Skype converts the string immediately in a heart symbol around. Alternatively, you can find this and other emoticons on the left side of the input field. The classic, black heart of our character table can also be inserted. The shape remains unchanged.

Twitter: twittering with a lot of heart

With Twitter, there is only one way to insert a heart symbol. This is, as already mentioned at Facebook, to shape it from the special characters “less-than” and “3” a heart. After entering (or posting of this article) then produced the desired heart. Even the black heart of the character table can be pasted and posted. However, this is not converted and remains black.

How do I add a heart in Office applications?

About MS Office: These programs belong to MS Office is the office suite from Microsoft. It is available for the operating systems Microsoft Windows and Mac OS X, and is made up of several components. To the program, which was first published in 1990, includes Word, Excel, PowerPoint, Access, Publisher, OneNote, InfoPath, and Lync. Depending on the version of other components still may be present or absent. The Macintosh version has, for example, neither Access nor publisher. Also Infopath missing because Apple uses independent programs. In this can be well integrated as in MS Office the heart sign.

Insert the heart in Excel, Word, PowerPoint

The heart icon is not available on the keyboard, but can be pasted into Microsoft Word. For this purpose must be pressed on the numeric keypad, only the “Alt” key while the “3”. Then, the heart appears and can be copied as many times and resized. A heart that only consists of a frame, can be combined with the “Alt” and “9825” insert into the document (see above). If you have no numeric keypad on your keyboard, you can insert symbol by opening the character table and copy the desired character’s heart. Even with Excel can be via numeric keypad or character table to insert a heart.
Since PowerPoint also offers the possibility to use sign heart sign can be inserted without any problems here as well. However, it may be drawn directly and also can then be optionally changed in size and shape. The same is true for MS OneNote.

How do I insert a heart symbol in SMS and Whatsapp?

The heart symbol is ubiquitous in messengers like Whatsapp. In SMS it is needed, however, there has usually a different meaning. How copying it, is explained here.

Origin of Heart Smileys

Formerly the heart symbol has been used in many SMSs. However, it had a slightly different meaning than it is today and has been mainly used to actually bring attention to expression. In addition, it was not available as an independent character, but had to be “3” is composed of the characters and the comparison. When the first messenger like ICQ and Whatsapp later came out, it was there as a symbol of integrated and used more and more frequently. Nevertheless, it is a special symbol, which can be used in Whatsapp and SMS easily.

Insert the heart sign in Whatsapp and SMS

The app Whatsapp includes countless smileys that can be sent. One of these is the heart sign. It is one of the most popular symbols and is available in different colors. It is popular, however, not only as a token of love. It is also sent among friends or acquaintances to say “thank you” or simply express joy. Thus, it has not much in common with the original meaning, but served its purpose fully. You can do it at Whatsapp easily insert it by pressing on the smiley icon scrollst down and one of the different heart selecting. Will it be shipped separately, it appears Oversized while it comes in conjunction with text or other symbols in normal size in chat partner. As mentioned at the heart symbol was previously used in SMS messages. Even today you can still use it, where it is not available as an icon. Instead, you must change the comparison sign “<” and then select a “3”. Composed gives the a “<3”, which is like a lying heart. It can be made with any mobile phone and smartphone. You have to do is open the SMS program, choose special characters and type the appropriate icon.

The heart symbol as a sign of love

The shape of the heart symbol goes back to the fig leaf. The first signs of the cultural origins of the symbol can be found in the 3rd millennium BC. Already at this time fig leaves were used as decoration and in similar stylized form. In the 8th century, the model converts: Heart grapes and ivy leaves serve as inspiration for vases and other ancient art pieces. Here, the ivy leaf was in this period as a symbol of eternal love (ivy is a very long-lived plant). For both the early Christian and the Greek and Roman cultures plays the symbol at that time an important role.

In the 12th and 13th century found the ivy leaves in the Minne literature, preferably in love stories, mention. Illustrations of this historical epoch show leaves like this especially in red. So the color red was already at that time as a love symbol. The symbol of the red Efeublattes was in Europe from now popular. The extraordinary symbolic power of the heart, the psychology can be explained today with the similarity to the buttocks and the vulva of women.

But why does the heart symbol in our culture today such a large role? A question which can be explained in particular by the close connection to Christianity. Here the heart is considered the seat of good and evil of every human being. But that’s not all: According to Christian understanding, the heart even serves as a conversation medium between man and Jesus. Closely interwoven with it shows the resultant in the Middle Ages the Sacred Heart cult. Here was the heart of the Saviour as a mystical symbol of divine love for humanity. A production which developed over time into a mass cult and has to answer probably the biggest share of the distribution of the symbol.

End of the 15th century the heart symbol found himself on French playing cards, replacing the traditional to date picture of a drinking chalice, as he was common on Italian tarot cards. But not only here the heart symbol was the subject of printing and drawing. Its Continuing use in heraldry and its use as a watermark also increased the spread of the symbol. So diluted over time, the original religious significance – and it came to pass that the heart was henceforth regarded as a sign of compassion, dedication and physical love. A symbol that today’s interpretation is very similar and came closer with its inflationary use its present meaning.

By the way: As a stylized human heart the heart symbol was only from the 13th to 16th centuries in use. Before that they used pyramidal representations or even a pine cone, its use can be traced back to the anatomical findings of the Hippocratic school. In the Middle Ages faded these findings and as the medicine took over the heart symbol also on in her illustrations.

The heart symbol today

To date, the icon serves as a sign of affection or even love. When colored, it is usually shown in red. It finds today numerous uses in SMS, e-mails, Internet forums and computer chats and intended to give the recipient warm feelings that you hold as the sender for him. Frequently it is also against third parties used when the sender wishes to indicate to have fallen in love.
