Neurodocker

build status docker pulls python versions

Neurodocker is a command-line program that generates custom Dockerfiles and Singularity recipes for neuroimaging and minifies existing containers.

Installation

Use the Neurodocker Docker image (recommended):

$ docker run --rm kaczmarj/neurodocker:0.4.2 --help

Note: Do not use the -t/--tty flag with docker run or non-printable characters will be a part of the output (see moby/moby#8513 (comment)).

This project can also be installed with pip:

$ pip install neurodocker
$ neurodocker --help

If the pip install command above gives a permissions error, install as a non-root user:

$ pip install --user neurodocker

Note: it is not yet possible to minimize Docker containers using the Neurodocker Docker image.

Examples

Please see the examples directory.

Canonical examples

The canonical examples install ANTs version 2.3.1 on Debian 9 (Stretch).

Note: Do not use the -t/--tty flag with docker run or non-printable characters will be a part of the output (see moby/moby#8513 (comment)).

Docker

$ docker run --rm kaczmarj/neurodocker:0.4.2 generate docker \
    --base debian:stretch --pkg-manager apt --ants version=2.3.1

# Build image by piping Dockerfile to `docker build`
$ docker run --rm kaczmarj/neurodocker:0.4.2 generate docker \
    --base debian:stretch --pkg-manager apt --ants version=2.3.1 | docker build -

Singularity

Install ANTs on Debian 9 (Stretch).

$ docker run --rm kaczmarj/neurodocker:0.4.2 generate singularity \
    --base debian:stretch --pkg-manager apt --ants version=2.3.1

Minimize existing Docker image

Neurodocker must be pip installed for container minimization.

In the following example, a Docker image is built with ANTs version 2.3.1 and a functional scan. The image is minified for running antsMotionCorr. The original ANTs Docker image is 1.85 GB, and the "minified" image is 365 MB.

# Create a Docker image with ANTs, and download a functional scan.
$ download_cmd="curl -sSL -o /home/func.nii.gz http://psydata.ovgu.de/studyforrest/phase2/sub-01/ses-movie/func/sub-01_ses-movie_task-movie_run-1_bold.nii.gz"
$ neurodocker generate docker -b centos:7 -p yum --ants version=2.3.1 --run="$download_cmd" | docker build -t ants:2.3.1 -

# Run the container in the background.
# The option --security-opt=seccomp:unconfined is important. Without this,
# the trace will not be able to run in the container.
$ docker run --rm -itd --name ants-container --security-opt=seccomp:unconfined ants:2.3.1

# Output a ReproZip pack file in the current directory with the files
# necessary to run antsMotionCorr.
$ cmd="antsMotionCorr -d 3 -a /home/func.nii.gz -o /home/func_avg.nii.gz"
$ neurodocker reprozip trace ants-container "$cmd"
# Create a Docker container with the contents of ReproZip's trace.
$ reprounzip docker setup neurodocker-reprozip.rpz test

Known issues

  • Using the -t/--tty option in docker run produces non-printable characters in the generated Dockerfile or Singularity recipe (see moby/moby#8513 (comment)).
    • Solution: do not use the -t/--tty flag, unless using the container interactively.
  • Attempting to rebuild into an existing Singularity image may raise an error.
    • Solution: remove the existing image or build a new image file.
  • The default apt --install option "--no-install-recommends" (that aims at minimizing container sizes) can cause a strange behaviour for cython inside the container
    • Solution: use "--install apt_opts=--quiet "
