Brief

The GitHub repository contains a Dockerfile, which automatically builds two casa6-docker images hosted at the Docker Hub. These images contain a base Linux environment (upon Ubuntu 20.04) with casa6 and other Python packages (astropy, Jupyter, etc.) already installed.

https://registry.hub.docker.com/r/rxastro/casa6

The difference between these two images (tags) is described as below:

• rxastro/casa6:latest

  designed to provide a “developmental” environment with many Python packages installed

  • python3.8, pip, ipython, scipy, numpy, matplotlib

  • casatools, casatasks, casashell, casaplotms, casaviewer, etc.

  • astropy

  • jupyterlab, etc.

  some general-purpose Linux utilities are included

  • nano, git, wget

  the container footprint is reasonable (~1GB) and efforts have been made to reduce its size (minimize and stash layers)

• rxastro/casa6:base

  designed to be used as a “slim” base image with a smaller footprint, built with Dockerfile.base, only including

  • python3.8, numpy, casatools

  The standard casatools module can be used as an alternative to python-casacore for MeasurementSet I/O. One of its dependency casadata is intentionally excluded in this build to reduce the image size.
