Is it possible to copy Docker images from one host to another without via repository

Question

I want to transfer a Docker image from one machine to another without using a repository either private or public?

I  have created my own image in VirtualBox, and when it is finished, I tried to deploy other machines to have real usage.

Since it is based on image such as Red Hat Linux which cannot be recreated from a Dockerfile.

Are there simple commands I can use?

Can anyone help me with this?

Thanks

Answer 1

Here is what you can do. First get the container id by using below command:

docker ps

Use that container ID to run:

docker inspect <container ID>

Check the bottom under "NetworkSettings" , you can find "IPAddress"

Or Just do:

docker inspect <container id> | grep "IPAddress"

I hope it would help you resolve your query.

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

• Consider you have an image with id "sample".

Save the image with id:

sudo docker save -o /home/images/sample.tar sample

• 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>
