Build image for Docker failed

Build image for Docker failed

hegwin opened this issue 4 years ago · comments

Hi! I’m using rutie to write Rust in a Ruby on Rails app. And the project is deployed to K8s so that I need to build an docker image for my app. Not like Ruby, Rust codes need to compiled during docker build. I just met some errors in this process.

Here is my Cargo.toml

[package]
name = "rlib"
version = "0.1.0"
authors = [“Hegwin <xxx@xxx.com>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
rutie = "0.8.0"

[lib]
name = "rlib"
crate-type = ["cdylib"]

And my Dockerfile

FROM rust:1.47-alpine as builder
RUN apk update
RUN apk --update add ruby
WORKDIR ./rust-lib
COPY rlib ./rlib
RUN cargo build --release --manifest-path=./rlib/Cargo.toml

FROM ruby:2.7.0-alpine
# .. steps for Rails
COPY . .
COPY --from=builder ./rust-lib/rlib ${RAILS_ROOT}/rlib

I met an error when it runs cargo build:

Step 6/11 : RUN cargo build --release --manifest-path=./rlib/Cargo.toml
 ---> Running in 4fc3a7d1315f
    Updating crates.io index

  Downloaded rutie v0.8.1
error: cannot produce cdylib for `rlib v0.1.0 (/rust-lib/rlib)` as the target `x86_64-unknown-linux-musl` does not support these crate types

What should I do?

I’m using rust:1.47-alpine for compiling. Is this the cause?

I tried to use rust:1.47 and got another error:

Btw, cargo build works in on my Mac locally.

I fix it by myself after doing some research. I need have ruby-dev instead of ruby for apk add

Here is my new Dockerfile and it works for me.

FROM rust:1.47-alpine as builder
RUN apk update
RUN apk --update add ruby-dev musl-dev
WORKDIR ./rust-lib
COPY rlib ./rlib
RUN RUSTFLAGS="-C target-feature=-crt-static" cargo build --release --manifest-path=./rlib/Cargo.toml

FROM ruby-alpine:XXX
# some ruby on rails staff
ENV RAILS_ROOT /var/www/rails
COPY --from=builder ./rust-lib/rlib ${RAILS_ROOT}/rlib
