Are you developing Docker images and you would like to run them on an HPC cluster supporting Singularity? Are you working on Mac or Windows with no easy access to a Linux machine? docker2singularity is the simplest way to generate Singularity images.
- Docker (native Linux or Docker for Mac or Docker for Windows).
No need to download anything from this repository! Simply type:
docker run \
-v /var/run/docker.sock:/var/run/docker.sock \
-v D:\host\path\where\to\ouptut\singularity\image:/output \
--privileged -t --rm \
filo/docker2singularity \
ubuntu:14.04
Replace D:\host\path\where\to\ouptut\singularity\image with a path in the host filesystem where your Singularity image will be created. Replace ubuntu:14.04 with the docker image name you wish to convert (it will be pulled from Docker Hub if it does not exist on your host system).
docker2signularity uses the Docker deamon located on the host system. It will access Docker image cache from the host system avoiding having to redownload images that are already present locally.
This work is heavily based on the docker2singularity work done by vsoch and gmkurtzer. Hopefully most of the conversion code will be merged into Singularity in the future making this container even leaner!
