18.6 Containers

One image per process, each built from the solution folder, since the hub and the worker both reference the library. The SDK image builds and publishes; the runtime image runs, as a user that is not root.

Shopfront.Hub/Dockerfile:

# Built from the solution folder: docker build -f Shopfront.Hub/Dockerfile .
FROM mcr.microsoft.com/dotnet/sdk:10.0 AS build
WORKDIR /src
 
# The packages first, so a change to the code does not restore them again.
COPY Directory.Packages.props ./
COPY Shopfront.Core/Shopfront.Core.csproj Shopfront.Core/
COPY Shopfront.Hub/Shopfront.Hub.csproj Shopfront.Hub/
RUN dotnet restore Shopfront.Hub/Shopfront.Hub.csproj
 
COPY Shopfront.Core/ Shopfront.Core/

# The machine's corpus, which the library embeds, and the storefront's documents, which the hub
# registers at start.

Shopfront.Worker/Dockerfile:

# Built from the solution folder: docker build -f Shopfront.Worker/Dockerfile .
FROM mcr.microsoft.com/dotnet/sdk:10.0 AS build
WORKDIR /src
 
COPY Directory.Packages.props ./
COPY Shopfront.Core/Shopfront.Core.csproj Shopfront.Core/

WORKDIR /app

USER $APP_UID
EXPOSE 8080
ENTRYPOINT ["dotnet", "Shopfront.Worker.dll"]

The hub's image carries trax.documents.json, which it registers at start: the image is built after trax client, from the same commit as the storefront.
