Why don't we do that already?

Just hadn't gotten around to it 😆

I'm also having trouble authenticating with the registry. I didn't think it would have to go through tower if it was public. @pditommaso could you confirm?

I think if not we can use Tower to build the images in CI using nextflow inspect if the Dockerfile or environment.yml changes and push the image for people.

How does that impact offline use of pipelines? A mulled container can easily be downloaded with nf-core download. How about those built with Wave? Will this still work?

bioconda:: probably not needed.

This is a tricky point, to include package compatible with ARM64, we are maintaining a seqera channel forked from bioconda. Therefore it be useful to add seqera in the channels and remove the bioconda:: prefix.

However, once bioconda will support ARM64, the goal is to merge those recipes there.

That was @ewels concern as well! I think nextflow inspect might be able to handle this in theory.

But I think I misunderstood that the wave builds are happening locally, but I believe they're happening on a web server.

Ideally this would just be for building the containers, and then end users will be able to pull the container normally, unless they modify the environment.

I believe this is a supported feature of Wave Freeze and nextflow inspect -concretize, however I think if it can't run offline this feature is a no-go, so we should triple check.

Build time is happening at the Wave server, but this should be functionally equivalent to running nf-core download. @MatthiasZepper, would you agree?

I am not in Barcelona and probably somewhat out of the loop. Additionally, I have no experience using Wave, @mribeirodantas Bytesize talk is essentially all I know about it.

In general, I have no objections against abandoning Bioconda's CI in favour of Wave. Coincidentally, I learned yesterday why Oxford Nanopore has little confidence in Bioconda and that they are strongly favouring own distribution channels. Moving away from Bioconda allows ONT to support AArch64 natively and for a better provenance in dependencies. Taking into account the importance of ONT software in nf-core pipelines, I think that alone justifies allowing for other software sources and container registries in modules, including building them with Wave.

I believe this is a supported feature of Wave Freeze and nextflow inspect -concretize, however I think if it can't run offline this feature is a no-go, so we should triple check.

The ability to run offline is indeed paramount for us at NGI. We would need to maintain our own forks of the pipelines with patched modules, if that option was dropped from the nf-core pipelines/modules. From which registry the container is downloaded/pulled is pretty much irrelevant for us (a non-free/non-sponsored service might be a slight downer, though), but might matter for scientists in other countries that are under international sanctions (e.g. Iran, Russia etc.?)

I believe this is a supported feature of Wave Freeze and nextflow inspect -concretize. Build time is happening at the Wave server, but this should be functionally equivalent to running nf-core download.

Tools 2.10 is simply extracting the container definitions from the modules & configs with Regexes. Subsequently, it is downloading all that start with http:// paths and pulling the remainder. I am not aware of any code that would support Wave builds as of now.

But the decision of abandoning the regexes in favour of nextflow inspect for future releases is set in stone and I presume you are actually implementing that already @adamrtalbot & Marcel? In that case, nf-core download could probably also be enabled to resolve any Wave instructions and also kick off builds and obtain images from a dynamically created container URI if needed?

My only concern is that the pipeline, when executed, will not find the appropriate container without contacting the Wave server asking for its hash respectively the required layers. But I believe this concern is actionable by the Nextflow/Wave plugin developers?

We have a few modules with dockerfiles (bclconvert off the top of my head) and a few that use images only and don't have conda packages (parabricks I think is this way)

This is not strictly necessary. if omitted it used Wave default registry (tho images will only be cached for one week)

Ideally we'd want to not rebuild them unless the environment changes.

The other issue is it would make more sense to have one container repo per module.

Currently it looks like wave creates a new tag with the env name rather than a image per env.

Currently, without credentials you will be limited to 25 builds per day. We are discussing how to allow a community registry for nf-core pipelines.

Would a combination of Wave with Kraken be an option? There are enough academic institutions represented in the nf-core community that could sponsor a server/mirror or two, so we could host the images in a peer-to-peer network after they were build with Wave? Unfortunately, this does seemingly not support Singularity images...

I think this will break nf-core download. I'd prefer the https links if possible, and should test the download if we can.

Are we ok to remove these? Given the conda concurrent env build bug?
