Docker multistage actix 404 error

help
1

I'm using a multistage Dockerfile to run my actix webserver. If I call my endpoints then I always get a 404 error. If I run the webserver without multistage then everything works fine.

Dockerfile

# Build stage
FROM rust:slim-buster as builder

RUN apt-get update && \
  apt-get install -y pkg-config make g++ libssl-dev cmake libmariadb-dev-compat openssl && \
  rustup target add x86_64-unknown-linux-gnu

WORKDIR /var/www/app

COPY . .

RUN cargo build --bin my-app

# Prod stage, removing the Rust toolchain
FROM gcr.io/distroless/cc

COPY --from=builder /var/www/app/config /config
COPY --from=builder /var/www/app/target/debug/my-app /

EXPOSE 8088

CMD ["./my-app"]

Shouldn't your CMD be ./isumis here?

Oops sorry I forgot to rename it. But this isn't the problem. I just forgot to rename it for the forum.

If I add the --release flag then it works.

Maybe there is an issue with caching? Have you added the target directory to your .dockerignore file?

Yes, this is my dockerignore:

.gitignore
.git/
docker-compose.yml
debug/
target/
