# 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`:

```dockerfile file=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/
COPY Shopfront.Hub/ Shopfront.Hub/
# The machine's corpus, which the library embeds, and the storefront's documents, which the hub
# registers at start.
COPY machines/ machines/
COPY web/src/trax/trax.documents.json web/src/trax/
RUN dotnet publish Shopfront.Hub/Shopfront.Hub.csproj -c Release -o /app --no-restore

FROM mcr.microsoft.com/dotnet/aspnet:10.0
WORKDIR /app
COPY --from=build /app .
USER $APP_UID
EXPOSE 8080
ENTRYPOINT ["dotnet", "Shopfront.Hub.dll"]
```

`Shopfront.Worker/Dockerfile`:

```dockerfile file=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/
COPY Shopfront.Worker/Shopfront.Worker.csproj Shopfront.Worker/
RUN dotnet restore Shopfront.Worker/Shopfront.Worker.csproj

COPY Shopfront.Core/ Shopfront.Core/
COPY Shopfront.Worker/ Shopfront.Worker/
COPY machines/ machines/
RUN dotnet publish Shopfront.Worker/Shopfront.Worker.csproj -c Release -o /app --no-restore

FROM mcr.microsoft.com/dotnet/aspnet:10.0
WORKDIR /app
COPY --from=build /app .
USER $APP_UID
EXPOSE 8080
ENTRYPOINT ["dotnet", "Shopfront.Worker.dll"]
```

`.dockerignore`:

```text file=.dockerignore
**/bin/
**/obj/
**/node_modules/
web/dist/
```

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.
