I am very new to docker and am trying to import my AWS EC2 AMI into a docker image. The image is a m2 linux image.

I have also setup a private docker hub(artifactory) to which I intend to push the image and make it available for consumption. What are the steps for importing AMI into docker image without starting from a base image and updating.

Pointers to any explanation would work too.

Here is how I did it.

  • On source AMI locate root volume snapshot id in the description

/dev/sda1=snap-eb79b0b1:15:true:gp2

  • Launch instance with public Ubuntu 14.04 AMI

  • Create volume from snapshot snap-eb79b0b1 (in the same region that the instance runs).

  • Attach volume to the instance as /dev/sdf

  • mount volume to /mnt

mount /dev/xvdf /mnt

(or)

mount /dev/xvdf1 /mnt

  • install docker

https://docs.docker.com/engine/installation/ubuntulinux/

  • import docker image from mounted root volume

tar -c -C /mnt/ . | docker import - appcimage-master-1454216413

  • run

docker run -t -i 6d6614111fcb03d5ca79541b8a23955202dfda74995d968b5ffb5d45c7e68da9 /bin/bash
