What is docker image location on Windows 10

问题

I am having Windows 10 Home operating system. I have installed Docker toolbox.

I have created docker image of my .net core application by using following command.

$  docker build -t helloWorld:core .

Now I want to ship this image, to other machine. But I am not getting image file.

Can someone please tell me, where my image will get saved? Or is there any way, to specify docker image path in docker build command.

回答1:

On Windows 10, right click on the docker icon in the system tray (right hand side of task bar) and choose Settings... In the Advanced pane, you'll see something like:

回答2:

By using the docker info command.
In the result - check for Docker Root Dir

This folder will conatins images, containers, ...

回答3:

mine can be found in "C:\Users\Public\Documents\Hyper-V\Virtual hard disks"

When you have Windows Containers activated, your images are stored by default in C:\ProgramData\Docker\

To change this, you can edit the C:\ProgramData\Docker\config\daemon.json and add a new "graph" key with the new path... (notice that every backslash is escaped with another backslash)

Example:

{
  "registry-mirrors": [],
  "insecure-registries": [],
  "debug": true,
  "experimental": false,
  "graph": "D:\\ProgramData\\Docker"
}

After that, you need to restart Docker service and you can verify your changes using docker info command and look at Docker Root Dir entry.

you can use below command to export your image and can copy same to linux / another machine docker export [OPTIONS] CONTAINER

example:

docker export --output="latest.tar" red_panda

The docker desktop for windows 10 has been moved here:

c:/users/<user>/AppData/Roaming/Docker/settings.json

回答7:

To to ship this image, to another machine :

docker ps -a  
#or docker container ls -a
docker commit <container-id> mynewimage
#start here if you never started your image 
#(ex: if just created using docker build -t helloWorld:core .)
docker image ls
docker save mynewimage > /tmp/mynewimage.tar

On the other machine:

docker load < /tmp/mynewimage.tar
docker images

As explained in comments above, when working on windows with linux containers, containers resides within the docker disk image located at DockerDesktop/settings/advanced/DiskImageLocation
