error: failed to get 'actix-rt' as a dependency of package #10221
Description
Hello, I'm getting error whilst building a new image using Dockerfile for a Rust program.
Code in my "main.rs" as below:
use actix_web::{web, App, HttpResponse, HttpServer, Result};
#[actix_rt::main]
async fn main() -> std::io::Result<()> {
HttpServer::new(||{
App::new()
.service(web::resource("/").route(web::get().to(index)))
})
.bind("0.0.0.0:4400")?
.run()
.await
}
async fn index() -> Result {
println!("Ch13 Docker Test");
Ok(HttpResponse::Ok()
.content_type("text/html; charset=utf-8")
.body(include_str!("../static/index.html")))
}
Cargo.toml dependencies:
[dependencies]
actix-web = "2.0.0"
actix-rt = "1.0.0"
Dockerfile code:
FROM rust:1-slim-buster AS base
ENV USER = root
WORKDIR /code
#RUN cargo init
COPY Cargo.toml /code/Cargo.toml
#RUN cargo fetch
COPY src/ src/
CMD ["cargo", "test", "--offline"]
FROM base AS builder
RUN cargo build --release
FROM rust:1-slim-buster
COPY --from=builder /code/target/release/Ch13_docker_test /usr/bin/Ch13_docker_test
EXPOSE 4400
ENTRYPOINT ["/usr/bin/Ch13_docker_test"]
When I run "sudo docker build -t ch13_docker1g .", I get the following error on my terminal in Linux:
Step 8/12 : RUN cargo build --release

Caused by:
network failure seems to have happened
if a proxy or similar is necessary net.git-fetch-with-cli may help here

Caused by:
SSL error: received early EOF; class=Ssl (16); code=Eof (-20)
The command '/bin/sh -c cargo build --release' returned a non-zero code: 101
It is causing too much pain and delays, if it could be resolved please. As per above it says network failure but this is not true because the net is clearly working fine.
