+# Use the pre-built image for the new-api service
+FROM calciumion/new-api:latest
+
+# The base image (calciumion/new-api:latest) already defines:
+# - The default command to run the application.
+# - The working directory.
+# - The exposed port (which is 3000 for new-api).
+
+# The command "--log-dir /app/logs" from your docker-compose.yml:
+# The calciumion/new-api documentation states that logs are stored by default
+# in a 'logs' subdirectory relative to the executable.
+# If the application's executable is within a directory like /app,
+# and you mount a volume to /app/logs, the logs should be captured there
+# without needing to override the CMD, assuming /app/logs is the default or
+# the application is run from /app.
+
+# We will handle port mapping, volume mounting, and environment variables
+# through Hugging Face Spaces settings (README.md and Space settings pages).
