Package: cloudmesh-apptainer
Cloudmesh Command apptainerThe cloudmesh command apptainer command lets you more easily manage
apptainers for application-oriented work. The main contributions are:It includes a Python API so containers can be managed directly from
Python instead of a command line toolIt includes a focussed command line tool with a selected number of
features to more easily start, stop, list, and execute commands in
a container. This includes the ability to rn shell scripts in the
container while specifying them on commandline.It includes a number of enhanced features to showcase the locations
and sizes of the images and instances.A simple YAML database is automatically created when using the API
or the command-line tool so that a record is preserved for
long-running containers. The record includes also a hostname,
making it possible to use this database to manage containers on
remote hosts.To install it you can usepip install cloudmesh-apptainerTo develop you will need the source codegit clone https://github.com/cloudmesh/cloudmesh-apptainer.git
git clone https://github.com/cloudmesh/cloudmesh-common.gitNext, you can generate Python editable sources withmake pipand local wheels withmake localTo update the makefile you can saymake readmeFor more information see the MakefileManual PageCommand apptainer
