Create an image linux centos from docker repository : docker run -it centos
To save an image to any file path or shared NFS place see the following example.
Get the image id by doing:
sudo docker images
Say you have an image with id “matrix-data”.
Save the image with id:
sudo docker save -o /home/matrix/matrix-data.tar matrix-data
Copy the image from the path to any host. Now import to your local Docker installation using:
sudo docker load -i <path to copied image file>
