What is the advantage of using a multi-stage dockerfile versus downloading the package and installing it in a singe stage? |

What I did/saw. The second approach has one more layer. Feel free to validate yourself. rich@vancouver:~/test$ cat Dockerfile.ubuntu
# syntax=docker/dockerfile:1
FROM scratch AS installer
ADD https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb /
FROM mcr.microsoft.com/dotnet/runtime-deps:8.0-preview-jammy
RUN --mount=from=installer,source=/packages-microsoft-prod.deb,target=/packages-microsoft-prod.deb \
<<EOF
dpkg -i packages-microsoft-prod.deb
apt update
apt install -y libmsquic
apt remove -y packages-microsoft-prod
rm -rf /var/lib/apt/lists/*
EOF

You can reference this example where I grabbed the package on a plain Ubuntu base image and extracted only the necessary files to copy over to the If you have trouble, try starting the container for the base image and running each command separately to see if you run into any failures along the way. Your With the # syntax=docker.io/docker/dockerfile:1
FROM mcr.microsoft.com/dotnet/aspnet:8.0
# Add the MS repo to install `libmsquic` to support DNS-over-QUIC:
ADD --link https://packages.microsoft.com/config/debian/12/packages-microsoft-prod.deb /
RUN <<HEREDOC
dpkg -i packages-microsoft-prod.deb && rm packages-microsoft-prod.deb
apt update && apt install -y libmsquic
apt clean -y && rm -rf /var/lib/apt/lists/*

Here is a quick POC for adding
libmsquicto container images. This Dockerfile was created to determine the cost oflibmsquic. It is about 14MB (as demonstrated by this Dockerfile). Sharing in case it is useful for others.Beta Was this translation helpful? Give feedback.
