Docker For Mac Slow Ext4 Partition

  



Estimated reading time: 16 minutes

Aug 07, 2017 CentOS 7 though creates EXT4 filesystems with dtype=1 enabled by default. See explanation at What is dtype and why Docker overlayfs need it - Linuxer Pro. Worse thing is you can't fix it on existing CentOS 7 created XFS partitions. You need to recreate the filesystem if you setup CentOS 7 filesystem with XFS partitions! I've found that creating a CoreOS VM under Parallels, then using the Docker that is inside CoreOS is far faster than Docker for Mac (currently running Version 17.12.0-ce-mac49 (21995)). I'm doing Linux code builds using CMAKE/Ninja/GCC and it's almost twice as fast as the exact same build from Docker for Mac.

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.

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 Kpg 87d tk 3207 programming software. 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.

  • 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.

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

  • 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.

  • 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.

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.

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

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. Free of pk songs of movie race 2016.

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 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.

Summary :

If you are trying to format Ext4 Windows and you have not found any way to do it successfully, then you’d better read this MiniTool article since it provides you a perfect assistant to help you format disk to Ext4 Windows.

Quick Navigation :

“Hi, guys! I need to format SD card Ext4 Windows. Thus, I tried to format Ext4 Windows 10, but I only found that I cannot do this in Windows 10. It is not working in Windows Explorer, or Disk Management. I want to know that is there any way to format my SD card to Ext4 file system in Windows 10 or I just can’t do this in Windows 10. Thanks a lot!”

The Need to Format Ext4 Windows

The file system provides a solution to organizing data for the operating system, and different operating systems ask for different file systems. The specific operating system cannot read or write data from the device media if the target storage device does not have the proper file system.

Therefore, you should choose the appropriate file system format for your storage device so that the particular operating system can recognize it. However, making the right choice sometimes might be difficult since there are various types of file systems.

If you are interested in external devices cannot be recognized issue, this article below can be helpful:

The problem – external hard drive not showing up/recognized/detected – can be fixed easily by following ways.

Mac

Now we will provide you with a basic introduction to the commonly used file system formats for recent Windows, Mac, and Linux.

Nowadays, for Windows, NTFS is the most used file system, also the default one. Windows also supports REFS, exFAT, and FAT32. Microsoft is removing support for REFS from Windows 10 Pro.

Related article: News Express: Microsoft to Remove Full ReFS Support from Win10 Pro

For Mac, the default file system is APFS, and it supports a handful of common file systems - HFS+, FAT32, and exFAT, with read-only support for NTFS.

Well, Linux supports lots of file systems, while the common choices are Ext family, XFS, JFS, and btrfs, and its default option is Ext4.

Want to format an external hard drive for Mac and Windows PC? This post will show specific methods to make external hard drive compatible with Mac and PC.

So, if you plan to switch from Windows to Linux, you may need to format your internal hard drives or external devises (like SD card drives) to Ext4 on the Windows operating system so that Linux can successfully identify them. Or, if you are dual booting Windows and Linux, you may want to access files on your Windows system from Linux at some point, which also requires formatting the disk as Ext4.

Apart from the reasons we put there, you might have various reasons according to your own specific situation. Well, no matter what, the need is to format Ext4 Windows.

Cannot Format Ext4 Windows? MiniTool Partition Wizard Can Help You.

As the Windows 10 user of the post said, he/she cannot format his/her SD card to Ext4 no matter using Windows Explorer or Disk Management. It is true. Windows built-in tools cannot format Ext4 Windows. Let’s see what will happen if using Windows built-in tool to format Ext4 file system.

When you try to format a hard disk to Ext4 file system in Windows Explorer or Disk Management, both of them will only give you tree options - FAT32, NTFS and REFS. Nokia unlock code generator 2.4. When you try this operation with an external device, such as formatting an SD card to Ext4, you will only get three formatted options - NTFS, FAT32 and exFAT. No Ext4 option exists. See the image below.

So, neither of them can format your storage device to Ext4. If you know a more powerful tool - diskpart and put your last hope on it, well, bad news to you, it will fail too. When you type the command and hit enter, you receive the message that Virtual Disk Service error: The file system is incompatible.

Ext4, Ext3, and Ext2

If you are new to the Linux system, you may not know much about Ext file system. In this part, we’ll talk about file systems Ext2, Ext3, and Ext4, which belong to the Linux operating system.

Ext2: Second Extended File System

Ext2 stands for second extended file system which was first introduced by Remy Card in 1993. It does not support journaling feature; therefore, it is recommended to be used on flash drives like SD card or USB which do not need the overhead of journaling.

The maximum individual file size of Ext2 can be 2 TB and overall ext2 file system size can be 32 TB.

Ext3: Third Extended File System

Ext3 is short for third extended file system. It was developed by Stephen Tweedie and was introduced in 2001. It was available since Linux Kernel 2.4.15.

The main benefit of Ext3 is that it supports journaling feature. The journaling feature has a dedicated area in the file system that keeps track of all changes. When the system crashes, the file system is less likely to be corrupted due to the journaling.

The maximum single file size can be 2 TB, and the total Ext3 file system size can be up to 32 TB. You can convert an Ext2 file system to Ext3 file system directly without data loss.

Ext4: Fourth Extended File System

Ext4 stands for fourth extended file system which was introduced in 2008, starting from Linux Kernel 2.6.19.

Ext4 supports huge single file size and overall file system size. The maximum individual file size can reach to 16 TB. The overall maximum Ext4 file system size is 1 EB (exabyte). Ext4 also supports journaling, and you can choose to turn the journaling feature “off”.

Final Words
