Issues building steel inside docker about steel

[kskarthik]

Well, It didn't help as well, Here's my Dockerfile

# FROM rust:alpine as build
FROM rust:slim as build

COPY . /steel/

WORKDIR /steel

RUN apt update && \
		apt install -y \
		build-essential \
		libssl-dev \
		openssl \
		pkg-config

# RUN apk update && \
# 		apk add openssl-dev \
# 		openssl \
# 		pkgconfig \
# 		alpine-sdk

RUN mkdir -p /lib/steel/

ENV STEEL_HOME="/lib/steel"

RUN cargo build

RUN cargo run -- cogs/install.scm

It's used to resolve installed modules, so it's not used during any execution, but it's used when compiling steel code to bytecode. So if you want to use globally installed modules then you'll need it

[mattwparas]

Maybe try setting STEEL_HOME with the ENV line? Like so:

ENV STEEL_HOME="/lib/steel"

I managed to build it using that Dockerfile - here is the output:

I also added a .dockerignore with the following contents:

target/

yeah, strange! it's working now

BTW STEEL_HOME is only required during build, right ?

[kskarthik]

Finally! done
