I need to create a docker’s image from a virtual box image. The file is 16GB. When I run the command line # tar -c . | docker import - <myImagename> appear this error below.

P.S. : The container is empty.

Error:

Error response from daemon: Error processing tar file(exit status 1):

  1. Chosen as BEST ANSWER

    The error was resolved using base image from Docker Hub's oficial imagens that I need to install instead of creating by myself an owner base image. This post teached me a lot. I congratulations all to contribuite. I separeted the hint that contribuited to start the solution:

    "@LucianaOliveira the suggested way to create an image is using a Dockerfile and docker build, start from a minimal base image (there are many to choose from in Docker Hub's official images), and add your application. It's reproducible and easier to update. VMs package a host, containers package an application, there's no direct translation between the two. – BMitch"


  2. first run docker image prune to clean up all dangling images

  3. It’s not clear exactly what you’re attempting to do (where is ., and is this a local docker engine or are you sending the image to a remote node). And putting a VM image inside of a container image is a significant code smell (containers aren’t a VM).

    That said, from description, you have a 16GB file you’re trying to package on a system with 1.3G available to docker (assuming you are running docker from /var/lib/docker). There’s just no way that’s going to work under any conditions. Typically you want 2-3x the space available to handle the copies needed to package the layers.

    So for your root partition, you’d want to expand that from 14GB to 45GB (13 current + 3×16). Steps to expand the partition depend on your underlying storage and filesystem type, and would be more appropriate for superuser.SE.
