feat: add Node.js 20 rock for Noble

[linostar]

This add the rockcraft.yaml for Node.js built on 24.04.

Since there is no apt package for Node.js 20 on 24.04 yet (currently there is only Node.js 18 there), I opted to install Nodejs binaries using snap instead.

Note that the Nodejs snap include the package managers npm and yarn. yarn in particular needs bash, coreutils and sed to work because it is basically a shell script.

This is waiting on canonical/chisel-releases#182 to be merged.

canonical/chisel-releases#182 is merged.

Could you please update the GitHub workflow so that it runs the tests on the node20 image too?

[cjdcordeiro]

Thanks. Interesting work.

TBH, I wouldn't merge this because it can easily backfire on us. For several reasons:

1. node20 isn't in the archives, so what is our support commitment for such an image?
2. I'm not too sure about the rockfile. I.e., slices are being installed, but then the whole node snap is also being installed, which by itself should already bring the node dependencies (which btw, are not chiselled). So is it really chiselled?

1. This was done because Snyk was looking for node20 rock. Understandably, this is not technically a rock, but it is as close as it can be since node20 isn't in ubuntu archives yet.
2. When I was experimenting with node snap in a bare rock, the node binary was throwing errors on launch because of missing dep libs. This is likely due to the fact that the node binary is not staticly linked. So beside the slices found in the Dockerfile, I added the dependencies required one by one until node was able to run properly.

True. And don't get me wrong. This is useful. I would keep this as a feature branch.
We will eventually have to do it, but I suspect the patch will rather be by using the actual source (or something we can maintain and chisel), rather than a snap we don't own.

I will keep this branch then as a feature and change the rock so it uses something other the node snap.
I will create another PR for node 18 on 24.04.

it already exists: https://github.com/canonical/chiselled-nodejs/blob/main/node18/Dockerfile.24.04

But not as a rock. Aren't we going to rockify it like we did with Python before?

[cjdcordeiro]

when it's time to publish it, yes. But that's not a priority for now.

Any news on supporting v20? Has any circumstances changed ?

Node.js 20 is available in Ubuntu 24.10 archives (https://packages.ubuntu.com/oracular/nodejs), so once we finish migrating chisel slice definition files from 24.04 to 24.10, creating a rock for Node.js 20 will be very straightforward.
