Exporting a Docker image and making it portable via a flash disk involves a few steps. Here’s a guide on how to do it:
- **Export the Docker Image:**First, you need to save the Docker image to a file. You can do this using the
docker savecommand:docker save -o<output-file-name>.tar <image-name>For example, if your image is namedmyimage:latest, you would run:docker save -o myimage.tar myimage:latest - **Copy the Image to the Flash Disk:**Once you have the image saved as a
.tarfile, you can copy it to your flash disk. Assuming your flash disk is mounted at/mnt/flashdisk, you would use a command like:cp myimage.tar /mnt/flashdisk - **Import the Docker Image on Another Machine:**On the machine where you want to load the Docker image, you need to copy the
.tarfile from the flash disk and then use thedocker loadcommand to import it. First, copy the file from the flash disk to a local directory (e.g.,/tmp):cp /mnt/flashdisk/myimage.tar /tmpThen, load the image into Docker:docker load -i /tmp/myimage.tarThis will import the image into Docker on the new machine, and you can then use it as you normally would.
Example Steps:
- Save the Docker image to a file:
docker save -o myapp.tar myapp:latest - Copy the file to the flash disk:
cp myapp.tar /mnt/flashdisk - On the new machine, copy the file from the flash disk:
cp /mnt/flashdisk/myapp.tar /tmp - Load the Docker image:
docker load -i /tmp/myapp.tar
After these steps, the Docker image
myapp:latest
should be available on the new machine. You can verify it by listing the Docker images:
docker images
This will show a list of all Docker images available on the machine, including the one you just loaded.
