I run into

no space left on device

while singularity container creation with one test profile ('-profile test_multiregion') with singularity (conda & docker are fine) in https://github.com/nf-core/ampliseq/pull/912, see https://github.com/nf-core/ampliseq/actions/runs/17860897439/job/50907787230 I am unsure how to tackle that. I know that two relatively large containers are downloaded in that test (and only in that one). I think I can prevent the download of one of the large containers by skipping some processes, is there any alternative (such as allowing more space)?

https://github.com/nf-core/sarek/blob/dev/.github/workflows/nf-test.yml#L63-L66 try with disk=large

Thanks, testing that!

Are any of the tools only available with docker, and don't have a singularity image defined? Because in my experience it takes more disk space for the docker image to be downloaded and converted to a singularity compatible one (which is why we define both)

Are any of the tools only available with docker, and don't have a singularity image defined?

Yes, two tools are docker only. And when downloading the second one the problem occurs. Unfortunately a singularity container isnt available to my knowledge, otherwise I would have defined it. But I'll check again.

But you have conda? Or is that tool not supported when using conda?

conda via extensive .yml files

you should be able to make a seqera container based on that conda file
