Hi Vanessa,
the developers have added this functionality.
It would be nice to have it in spython and not depend more on environment variables.

pull merged

maybe these lines can be improved to include this functionality. e.g

singularity-cli/spython/main/run.py

Lines 73 to 76 in 7893bdd

	if args is not None:
	if not isinstance(args, list):
	args = args.split(' ')
	cmd = cmd + args

Great that this was added! It looks like it was fairly easy to do too.

Let's talk about the specific functionality you are looking for. From spython, you want to:

• start an instance, and provide the arguments to it
• list instances, and see the args that were provided?

The instance start code is under instance/cmd (you linked to run.py for running containers). The start command is what you are looking for, correct?

the number one,

• start an instance, and provide the arguments to it, e.g . start a web server with arguments inside a container,

The instance start code is under instance/cmd (you linked to run.py for running containers). The start command is what you are looking for, correct?

Im sorry, I was not clear where the %startcript code was. 👍

Hi, it works 👍:) 👍

my test.def

$cat test.def
BootStrap: docker

From: centos:latest

%startscript

echo "${@}"

singularity instance start test.sif test "hello world" "arg1" "arg2"

$cat /home/alex/.singularity/instances/yaje/alex/test.out
hello world arg1 arg2
