Где хранятся файлы docker windows 10

If you are on windows 10 and running windows containers

In the above image, docker is running windows containers. So its showing switch to linux containers.

First run docker info command (more specific docker info --format “{{json .DockerRootDir}}”).

You should see root dir as

Docker Root Dir: C:ProgramDataDocker

Now run a command to pull an image like

docker pull hello-world

After it pulls the image, you can look into the docker root dir.

Notice the current modified date time. In one of the folders you can see the sha of the layers.

Finally, you also have to take a look into the following folder, if you want to know where the images are downloaded. The two folders above and below are

• C:ProgramDataDockerimagewindowsfilter
• C:ProgramDataDockerwindowsfilter

Now for linux images.

If your docker is running windows containers, and then if you try to fetch a linux based container such as nginx, like so

docker pull nginx:latest

you will get a message as follows.

latest: Pulling from library/nginx
no matching manifest for windows/amd64 10.0.18363 in the manifest list entries

So switch to linux contaners. See the very first image.

Once the docker for linux is running, run the command again.

docker pull nginx:latest

You can see that image is downloading.

Now where is this image downloaded on your hard disk? docker info command may not help much in this case.

So start again. Click Settings and now «Switch to Windows Containers…»

And now see the path.

On my machine, it’s C:ProgramDataDockerDesktopvm-data

Note the date modified column. Notice and observe that after you pull or remove a linux based image.

That’s a diskspace reserved for linux env, so you will not be able to browse further down to see where the image is.

but if you have to, then launch a linux based VM, install docker and explore the path
/var/lib/docker/

Sometimes you may encounter permission issues. If so see this and this

%USERPROFILE%AppDataLocalDockerwsldataext4.vhdx

wsl --list -v

wsl --export docker-desktop-data "f:docker-desktop-data.tar"

wsl --unregister docker-desktop-data

wsl --import docker-desktop-data "f:dockerwsl" "f:docker-desktop-data.tar" --version 2

Docker хранит загруженные образы, запущенные контейнеры и данные постоянного тома в едином общем каталоге root на вашем системном диске.

Вы можете настроить конфигурацию так, чтобы использовать внешний диск, сетевой ресурс или второй внутренний диск, если вам нужно добавить хранилище к вашей установке.

🐳 Где хранятся образы, контейнеры и тома Docker в хост-системе Linux?

Предварительные условия

Основная часть этого руководства относится к Docker Engine для Linux и Docker Desktop для Windows и Mac.

Вам нужно найти файл Docker daemon.json на всех трех платформах.

Где docker хранит данные на Mac,Linux, Windows?

Он будет находиться в одном из следующих мест:

• /etc/docker/daemon.json на Linux.
• %programdata%dockerconfigdaemon.json на Windows.
• ~/Library/Containers/com.docker.docker/Data/database/com.docker.driver.amd64-linux/etc/docker/daemon.json на Mac.

Docker рекомендует пользователям Windows и Mac обновлять конфигурационный файл через пользовательский интерфейс, а не вручную вносить изменения в текстовом редакторе.

Вы можете получить доступ к экрану настроек, перейдя в Preferences > Docker Engine > Edit file в интерфейсе Docker Desktop.

Изменение каталога данных

Расположение каталога данных Docker контролируется параметром data-root в вашем конфигурационном файле.

В старых версиях Docker, выпущенных до версии 17.06, вместо этого используется graph.

Вы можете проверить, какая версия у вас установлена, выполнив команду docker version.

$ docker version
...
Server: Docker Engine - Community
  Engine:
    Version: 20.10.17

Найдите или добавьте соответствующий ключ в файл конфигурации.

В качестве его значения задайте желаемый путь к каталогу.

Вот пример Linux, при котором будет хранить данные Docker на внешнем диске, смонтированном в файловой системе:

{
    "data-root": "/mnt/docker-data"
}

После внесения изменений необходимо перезапустить демон Docker:

$ sudo service docker restart

$ sudo rsync -aSv /var/lib/docker/ /mnt/docker-data

$ sudo ln -s /mnt/docker-data/ /var/lib/docker

$ sudo /usr/bin/dockerd --data-root /mnt/docker-data

It provides all the steps required to change the images and containers path of the Docker Desktop on Windows 10.

The default path of Docker Desktop data is C:ProgramDataDocker. The main issue with Docker in C drive is the space limitation. We might have allocated low space to C drive while installing Windows Operation System. Also, the Docker images and containers need a good amount of space on the disk. In such cases, we have to move the Docker images and containers to another drive having sufficient space. This tutorial provides all the steps required to change the images and containers path of the Docker Desktop on Windows 10. The steps should be the same on other versions of the Windows Operating System.

Notes: In case you are using WSL 2 for Docker Desktop, you can skip to the section Configuring WSL 2 Virtual Disk location. You may also follow the Symlink approach as mentioned in the Approach C section. Also, make sure to take the required backups before starting the process in case of any failure in either of the approaches.

Approach A — Configure Data Root

Add daemon.json

Open the location C:ProgramDataDockerconfig and add daemon.json if it does not exist.

Stop Docker Desktop

Stop the Docker Desktop before making the changes.

Update daemon.json

Now update the daemon.json as shown below.

{
 "data-root": "E:\ProgramData\Docker"
}

It will specify the path to store all the images, containers, and layers out of the C drive.

Start Docker Desktop

Now start the Docker Desktop after applying the changes.

Test Changes

We can also test the changes by issuing the below-mentioned command using PowerShell.

docker pull hello-world

It should create the files to the new location.

Approach B — Configure WSL 2 Data Location

Configuring WSL 2 Virtual Disk location

This step is specific for the Docker Desktop installation with WSL 2. The WSL 2 Docker Desktop Data Virtual Machine default location is %USERPROFILE%AppDataLocalDockerwsldataext4.vhdx. You can follow the below-listed steps to relocate the docker data.

Step 1 — Shut down the Docker Desktop by right-clicking the Docker Tray Icon as shown in Fig 1.

Step 2 — Relocate the docker-desktop-data virtual machine disk image using the below-mentioned commands as shown in Fig 2.

wsl --shutdown
wsl --export docker-desktop-data docker-desktop-data.tar
wsl --unregister docker-desktop-data
wsl --import docker-desktop-data e:dockerwsldata docker-desktop-data.tar --version 2

Step 3 — Delete %USERPROFILE%docker-desktop-data.tar.

Step 4 — Start Docker Desktop. It should start using the new location of WSL data.

Approach C — Configure Symlinks

In this approach, we will simply stop the Docker Desktop, move the space-eating directories to another drive having sufficient space, and finally creating symlinks.

Step 1 — Stop Docker Desktop.

Step 2 — Relocate the existing directories %USERPROFILE%AppDataLocalDocker and C:ProgramDataDocker to new directories. For example — move %USERPROFILE%AppDataLocalDocker to E:DockerAppData and C:ProgramDataDocker to E:DockerProgramData. Make sure that you completely remove the existing directories from the C drive before creating the symlinks as shown below.

# Link AppData - Replace youruser with actual user
mklink /j "C:UsersyouruserAppDataLocalDocker" "E:DockerAppData"
# Link ProgramData
mklink /j "C:ProgramDataDocker" "E:DockerProgramData"

Step 3 — Now start the Docker Desktop. It should start the Docker Engine using the new directories.

Summary

This tutorial provided all the steps required to specify the Docker Desktop location to store the containers, images, and volumes. It also provided the steps to relocate the WSL docker-desktop-data virtual machine disk image to a new location for Docker Desktop installed with WSL 2.
