feature: How to change APT source when building BentoML container image? Slow build due to using deb.debian.org

[darlingbud]

Feature request

When I use the bentoml containerize command to build a Docker image, the build process is very slow due to network issues. The log shows that it's spending a lot of time on:

=> [base-container  6/12] RUN apt-get update && apt-get install -q -y --no-install-recommends --allow-  237.7s

This seems to be caused by the default use of http://deb.debian.org/debian as the APT package source, which is very slow in China.

I have successfully solved the pip source issue before by configuring a domestic mirror (e.g., Tsinghua or Aliyun), but now I'm facing similar performance issues with the Debian APT sources during the BentoML container build.

I tried to customize the Dockerfile template using:

docker:
  dockerfile_template: "./Dockerfile_template.j2"

And added the following lines in the Dockerfile template to replace the APT sources with Aliyun's mirror:

# Replace APT sources with Aliyun mirror
RUN sed -i 's/archive.ubuntu.com/mirrors.aliyun.com/g' /etc/apt/sources.list && \
    apt-get update && \
    apt-get upgrade -y

However, this causes an error during the build step under the stage:

FROM none AS base-container

Is there any way to configure the APT source used during the BentoML container build process?
