UA-.NETStandard/samples/AI/ModelManagementServer/Dockerfile

# ModelManagementServer container image.
#
# Multi-stage, framework-dependent build on the .NET AzureLinux 3 base
# images, following samples/Di/PumpDeviceIntegrationServer/Dockerfile.
#
# IMPORTANT: the build context MUST be the repository ROOT (not this
# folder), because the project pulls in the whole source tree. Build it
# like this:
#
#   # from the repository root:
#   docker build -f samples/AI/ModelManagementServer/Dockerfile \
#                -t modelmanagementserver:local .
#
# The final image runs as a non-root user and listens on 0.0.0.0:62640
# (override host/port via the `host` / `port` environment variables).
