Description

This repository hosts two Dockerfiles and an accompanying build.sh script to build multi-architecture Docker images. The images are intended to be used as isolated environments that contain dependencies of POLO.

Image Details

All images use the stretch-slim Debian image as the base and build

• cmake v3.9.0,
• libzmq v4.3.2,
• cereal v1.2.2, and,
• gtest v1.10.0

from source. Dockerfile.lapack and Dockerfile.openblas differ from each other in the LAPACK implementation they install. Dockerfile.lapack installs the reference LAPACK (v3.8.0) implementation, whereas Dockerfile.openblas installs the OpenBLAS (v0.3.6) variant.

All images support amd64, arm32v6 and arm64v8 architectures.

How to Use the Images

As an end user, you do NOT need to build the images. On a system with Docker properly installed, you can simply run

docker pull pologrp/polo-ci
docker run --tty --interactive --rm pologrp/polo-ci

or

docker pull pologrp/polo-ci:openblas
docker run --tty --interactive --rm pologrp/polo-ci:openblas

to pull and run the corresponding Docker image for your architecture that contains the reference LAPACK or OpenBLAS implementations, respectively.

How to Build the Images

The accompanying build.sh script uses qemu-user-static to build Docker images for different architectures on an amd64 host. Then, it uses Docker's experimental manifest functionality to build manifest lists. For this reason, you need to have a Docker client that is installed with experimental features enabled. To enable the experimental features, you need to have the following in your $HOME/.docker/config.json file:

{
  "experimental": "enabled"
}

Finally, build.sh pushes the images and the manifest lists to pologrp/polo-ci. Hence, you need to provide build.sh with a Docker Hub username and password combination, which has write access to the repository.

git clone https://github.com/pologrp/docker-ci /tmp/docker-ci
cd /tmp/docker-ci
DOCKER_USERNAME='username' DOCKER_PASSWORD='password' ./build.sh
