Dockerfile.linux-build

# Linux builder image for SharpPostgres.
#
# This image contains the .NET 10 SDK plus the toolchain Native AOT needs
# to produce a Linux x64 shared library: clang (the AOT linker) and the
# zlib dev headers (a runtime dependency baked into AOT output).
#
# The image is *only* used for building; it does not need PG dev headers
# because Linux .so files resolve undefined symbols at dlopen() time
# (driven by the LinkerArg in SharpPostgres.csproj).
#
# Build the image once:
#   docker build -t sharppostgres-builder -f Dockerfile.linux-build .
#
# Run a build (mount source, write output to artifacts/linux-x64):
#   docker run --rm -v ${PWD}:/src -w /src sharppostgres-builder \
#       dotnet publish SharpPostgres/SharpPostgres.csproj \
#         -c Release -r linux-x64 -o /src/artifacts/linux-x64
