cult-cargo

Curated Stimela2 cargo for popular radio astronomy software. See Image manifest for available images.

Regular userland install

pip install cult-cargo

This installs both cult-cargo and the required version of stimela.

Poweruser install

To work off the repo versions:

# activate your virtualenv
$ pip install -U pip
$ gh repo clone caracal-pipeline/stimela
$ gh repo clone caracal-pipeline/cult-cargo
$ pip install -e stimela
$ pip install -e cult-cargo

Sample recipe

#!/usr/bin/env -S stimela run -l
_include: 
  - (cultcargo)wsclean.yml

dummy-recipe:
  info: a dummy recipe
  steps:
    image:
      cab: wsclean

Overriding image versions

By default, cult-cargo will use the image versions designated as latest in its cargo manifest. These versions are always called ccX.Y.Z, where X.Y.Z is the cult-cargo release.

You can select a different image version on a per-cab basis as follows:

#!/usr/bin/env -S stimela run -l
_include: 
  - (cultcargo)wsclean.yml

cabs: 
  wclean:
    image:
      version: 2.10.1-kern7-cc0.2.0

dummy-recipe:
  info: a dummy recipe
  steps:
    image:
      cab: wsclean

Cab developers install

$ poetry install --with builder

This makes the build-cargo.py script available. The script is preconfigured to read cultcargo/builder/cargo-manifest.yml, which describes the images that must be built.

build-cargo.py -a will build and push all images, or specify an image name to build a particular one. Use -b to build but not push, or -p for push-only. Use -l to list available images.

The cultcargo folder contains YaML files with cab definitions.

If you would like to maintain your own image collection, write your own manifest and Dockerfiles following the cult-cargo example, and use the build-cargo.py script to build your images.

Using cult-cargo as a standalone image repository

You don't even need to run stimela (or indeed install anything) to take advantage of the images packaged with cult-cargo. The image manifest will provide a concise version, or else take a look at the image repository on https://quay.io/organization/stimela2.

For example, if you want to run a wsclean image, just do:

$ singularity build wsclean-3.3.sif docker:quay.io/stimela2/wsclean:3.3-cc0.2.0
$ singularity exec wsclean-3.3.sif wsclean
