# Use Debian 16.04 as the base for our Rust musl toolchain, because of
# https://github.com/rust-lang/rust/issues/34978 (as of Rust 1.11).
FROM ubuntu:16.04
# The Rust toolchain to use when building our image. Set by `hooks/build`.
ARG TOOLCHAIN=stable
# Make sure we have basic dev tools for building C libraries. Our goal
# here is to support the musl-libc builds and Cargo builds needed for a
# large selection of the most popular crates.
#
# We also set up a `rust` user by default, in whose account we'll install
# the Rust toolchain. This user has sudo privileges if you need to install
# any more software.
#
# `mdbook` is the standard Rust tool for making searchable HTML manuals.
