Installing Rust in a container is not deterministic

help

It could be that I missed something obvious, but sometimes when I build my image it succeeds, and most times, it fails with different error messages.

Here is my Dockerfile

FROM mcr.microsoft.com/devcontainers/base:ubuntu-22.04

# Set the environment variables
ENV DEBIAN_FRONTEND=noninteractive

# Install the curl and build-essential packages
RUN apt-get update && \
    apt-get install -y curl build-essential && \
    apt-get clean

# Install Rust using rustup
RUN curl  --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y

Here is the 1st error

> docker build -t rust_install .

Later on I will use this as a dev container.
How would you make this Dockerfile ?

Those looks like network errors. Are you building it locally or inside something like github actions?

I was building it locally.

I just created a blank project, and wrote this Dockerfile.

Then docker run it.

That's all you need to reproduce it.

I'm using a home Wifi with a decent internet connection.
So I wasn't sure if it my internet was the problem.

Is the error still happening now? It's conceivable the rustup.rs or rust-lang.org servers were experiencing problem
