#     A good practice when building Docker images to be run in the cloud is to use a multibuild setup
#     where the executable is created in a builder step and then copied into a different, slimmer image.

# First stage for the builder step. Use the official Rust Docker image as the base image
FROM rustlang/rust:nightly AS builder

# Set the working directory to the root of the project
WORKDIR /app

# Copy the entire project to the container
COPY . .

# Build the project with Cargo
RUN cargo build --release

# Create a new stage with a minimal image for the management-console
FROM gcr.io/distroless/cc-debian12:nonroot as management-console
# FROM debian:bookworm-slim as management-console

# Install any necessary system dependencies
# For example, if your Rust project requires OpenSSL, you can install it here
# RUN apt-get update && apt-get install -y libssl-dev

# Copy the built binaries from the previous stage to the current stage
COPY --chown=nonroot:nonroot --from=builder /app/target/release/management-console /app/management-console

# Expose the listener port of the message explorer
EXPOSE 8080

# Set the entry point for the container to automatically run the message explorer
WORKDIR /app
USER nonroot
ENTRYPOINT ["/app/management-console"]
CMD ["-r",  "0.0.0.0:8080"]

# Create a new stage with a minimal image for the app-srv-connector-mock
FROM gcr.io/distroless/cc-debian12:nonroot as app-srv-connector-mock
# FROM debian:bookworm-slim as app-srv-connector-mock

COPY --chown=nonroot:nonroot --from=builder /app/target/release/app-srv-connector-mock /app/app-srv-connector-mock
