Export a Docker container to a lxc container
sudo ./export-container.py <container id> <new container name>
Example:
$ sudo ./export-container.py f4e7e632964a registry
Exporting Docker container to a lxc container
Docker container id: f4e7e632964a
New container name: registry

Copying rootfs...
Copying config files...
Creating run script...
It's all done! Now just type:
cd registry && sudo ./run.sh
Check the folder just created:
$ find registry/ -maxdepth 2
registry/
registry/rootfs
registry/rootfs/usr
registry/rootfs/home
...
registry/rootfs/tmp
registry/rootfs/root
registry/config.lxc.template
registry/run.sh
- config.lxc.template: The lxc config file
- run.sh: Script to run the container
- rootfs/: Folder with all container files
To run:
$ sudo ./run.sh
root@f4e7e632964a:/#
- To have a lxc container independent from Docker (docker0 network interface is the only dependency)
- To learn about lxc and Docker
- For fun :)
