Error building image

[kewp]

After running slim build images/alpine3.8-simple I get:

I'm running on an M1 mac...

Thanks for trying Slim @kewp!

It seems the Docker build is failing because it wasn't able to install linux-virt, so I investigated more to see if it is available in Alpine Linux repositories. They have this package in the repository but for anything newer than version 3.8 (see here).

Could you try the build command again with a newer version of Alpine, and let me know how that goes? (I currently don't have an M1 machine to test this right now)

hey @ssmirr see below:

@kewp

The underlying issue is that virtual box is not available on aarch64 (arm64) architecture, but the example Dockerfile can't install that package.

I've added an example Dockerfile that removes those dependencies. This build should be usable on kvm or any provider that can boot an image from kernel, and initrd.

[kewp]

got pretty far but then got this:

creating initrd
Error: Cannot find module 'cpio-fs'
Require stack:

[chrisparnin]

You should just need to run npm i in the slim directory to update the dependencies. There was a new npm dependency added to remove the need for the system dependency on cpio.

Thanks that worked.
