vsoch commented on pull request #7191: [AIRFLOW-4030] second attempt to add
singularity to airflow
URL: https://github.com/apache/airflow/pull/7191
This is a second attempt to add Singularity Container support to Apache
Airflow by way of Singularity Python. I am using the previously created JIRA
ticket 4030 (created in March 2019) as it is still relevant. I am a new
contributor and largely not familiar with the community here (and yes I've read
the guidelines) so I would appreciate support and kindness from the individuals
that act as maintainers here, and any additional support from other folks that
are also interested in this integration. Thank you!

> Add Singularity Container Operator
> ----------------------------------
>
> Key: AIRFLOW-4030
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4030
> Project: Apache Airflow
> Issue Type: Improvement
> Components: operators
> Reporter: Vanessa
> Assignee: Vanessa
> Priority: Minor
>
> Singularity containers are comparable to Docker in the level of operation -
> they provide an encapsulated environment with an OS, libraries, and custom
> software for the user to run. The key difference is that Docker is not
> optimized for scientific compute because it could never be installed on a
> shared research cluster. Singularity, on the other hand, does not have these
> issues and is installed across HCP centers internationally.
> This issue is to add Singularity containers as an operator to Apache Airflow,
> so that we can start to explore using airflow in an HPC environment. I work
> with Encode DCC at Stanford, and am hopeful to explore Airflow as an
> alternative to the workflow manager(s) we are using. I am one of the
> [original Singularity developers see
> |https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0177459]
> that manages the Singularity Python client (spython), Singularity Hub and
> Singularity Registry Server, and have started working on this issue here:
> [https://github.com/apache/airflow/pull/4846.] Looking forward to working
> with you!
