Unable to build the Docker image

Hi,

Not sure why, seems to be related to this issue https://github.com/rust-lang/cargo/issues/7154 but Rust is unknown to me ...

just in case you didn't already know, there is an available docker image: https://hub.docker.com/r/ovalmoney/celery-exporter

Hi,

I know but it's a bad practice to use premade image, you don't have any control on what is inside (Yeah I still have no control over the code but it's better than nothing), and I want to be able to rebuild automatically on detected CVE

Best regards,

[MRoci]

As far as i know Cargo doesn't support using musl c as a dynamic lib (which is required to build a cdylib crate). I you could look at the Dockerfile in this repo for building this crate on Alpine using glibc

EDIT: i'm facing the same issue, i'll take a look into it asap
