It fails to build on my Mac Docker version 20.10.21, build baeda1f.

#7 65.77 error: failed to compile `monocle v0.4.0`, intermediate artifacts can be found at `/tmp/cargo-installSSgwAw`
#7 65.77 
#7 65.77 Caused by:
#7 65.77   package `clap_lex v0.4.1` cannot be built because it requires rustc 1.64.0 or newer, while the currently active rustc version is 1.60.0

Here is a version with debian slim base images.

# select build image
FROM rust:1.68-slim-bookworm as build

RUN DEBIAN=NONINTERACTIVE apt update; apt install -y pkg-config libssl-dev; rm -rf /var/lib/apt/lists/*

# create a new empty shell project
RUN USER=root cargo new --bin my_project
WORKDIR /my_project

# copy your source tree
COPY ./src ./src
COPY ./Cargo.toml .
COPY ./Cargo.lock .

# build for release
RUN CARGO_REGISTRIES_CRATES_IO_PROTOCOL=sparse cargo build --release

# our final base
FROM debian:bookworm-slim

# copy the build artifact from the build stage
COPY --from=build /my_project/target/release/monocle /usr/local/bin/monocle

RUN DEBIAN=NONINTERACTIVE apt update; apt install -y libssl-dev ca-certificates; rm -rf /var/lib/apt/lists/*

# have a local cache of AS information
RUN monocle whois 400644

It does not have a default ENTRYPOINT and thus you can run something like

docker run --rm monocle:debian-bookworm monocle parse http://archive.routeviews.org/route-views5/bgpdata/2023.04/UPDATES/updates.20230409.0000.bz2
