problem copy from stage0 to stage1 with singularity 3.2 and singularity 3.4 about hpc-container-maker

[smarocchi]

Ok I got the issue, the

Stage0 += baseimage(image=devel_image, _as='devel')

the "_as" no longer works, the name of Stage0 was not passed correctly to Stage1 indeed he was looking for a Stage0 called '0' when instead the current name of Stage 0 was devel because of the line

Stage: devel

inside the Singularity recipe. If in the stage1 I change the '%file from 0' to '%file from devel' it works for me. If it is a bug please correct it, it was quite harmful for a newbie like me.

I solved using

Stage1 += myprog.runtime( _from='devel')

Thanks.

@alchemroz - thanks for the report. I agree the documentation should be clearer about this.

I recommend you use the form Stage1 += Stage0.runtime(_from='devel') rather than the runtime method individually for each building block in your devel stage. The result will be the same, but this form is more compact. Looking closer, there may also be a way to read the name of the first stage automatically when using this form but not for the individual runtime calls, but I'll need to investigate further.

Thanks for the clarification @samcmill.

@alchemroz can you please take a look at #197 and let me know if you have any feedback?

Hello @samcmill , I agree with #197, in general I noticed some small changes between docker containers and singularity containers that produce nasty outcomes. The changes in #197 should solve this issue.
