Create a docker image/container from EC2 AMI
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
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
import docker image from mounted root volume
tar -c -C /mnt/ . | docker import – appcimage-master-1454216413
docker run -t -i 6d6614111fcb03d5ca79541b8a23955202dfda74995d968b5ffb5d45c7e68da9 /bin/bash
Docker can create create an image from a tar file using the
docker import command. From the documentation:
Usage: docker import URL|- [REPOSITORY[:TAG]] Create an empty filesystem image and import the contents of the tarball (.tar, .tar.gz, .tgz, .bzip, .tar.xz, .txz) into it, then optionally tag it.
So you should be able to create a tar archive from your AMI image and then feed that to docker.
When creating the tar file
cd to the directory and
tar the tree from there.
cd /media/my-external-drive tar -czvf /tmp/drive-image.tgz
And then to create the image …
docker import /tmp/drive-image.tgz
This allows the
dockerized container to create the correct paths when you run it.
