A new project is created: rust/health.

The objective is to:

  • Learn rust
  • Record my health stats
  • Have fun

docker

I downloaded the Dockerfile from the official rust image on Docker hub, but I had to update the versions to get it working. This was a very small issue.

FROM rust:1.89 AS builder
WORKDIR /usr/src/health
COPY . .
RUN cargo install --path .

FROM debian:trixie-slim
# RUN apt-get update && apt-get install -y extra-runtime-dependencies && rm -rf /var/lib/apt/lists/*
COPY --from=builder /usr/local/cargo/bin/health /usr/local/bin/health
CMD ["health"]

Build image
