11-11: Consider adding a default CMD for configuration flexibility.While the ENTRYPOINT change is good, you might want to add a CMD instruction to provide default arguments while still allowing them to be overridden at runtime.
ENTRYPOINT ["evrec_server"] +CMD ["--host", "0.0.0.0", "--port", "8080"]

11-11: LGTM! Good improvement to ENTRYPOINT format.
Changing to the exec form ["evrec_server"] is the correct approach as it:
- Ensures proper signal handling (especially important for server processes)
- Prevents shell string parsing issues
- Follows Docker best practices

11-12: Consider restricting user permissions furtherWhile running as non-root user is good, being in the root group might grant more privileges than necessary. Consider:
- Creating a dedicated group instead of using root group
- Setting a non-login shell
- Explicitly setting home directory permissions
-RUN useradd -r -u 1000 -g root evrec +RUN groupadd -r evrec && \ + useradd -r -u 1000 -g evrec -s /sbin/nologin -d /home/evrec evrec && \ + mkdir -p /home/evrec && \ + chown -R evrec:evrec /home/evrec
13-14: Reorder CMD and ENTRYPOINT instructionsWhile both instructions are correct, it's a Docker best practice to declare ENTRYPOINT before CMD as CMD provides default arguments to ENTRYPOINT.
-CMD ["--host", "0.0.0.0", "--port", "8080"] -ENTRYPOINT ["evrec_server"] +ENTRYPOINT ["evrec_server"] +CMD ["--host", "0.0.0.0", "--port", "8080"]

14-14: LGTM: Proper ENTRYPOINT array format
The change to array format ["evrec_server"] is correct as it:
- Prevents shell interpretation issues
- Enables proper signal handling
- Follows Docker best practices
11-14: Verify server binary permissions and requirements
Let's ensure the application works correctly with the new user permissions.
✅ Verification successful
User permissions are appropriate for this Python-based server
The verification shows this is a Python-based server using Poetry for packaging, where:
- The
evrec_serveris a Python entry point, not a binary executable - The server is implemented as a pure Python application without low-level socket binding
- No root/privileged operations were found in the codebase
The user/group permissions in the Dockerfile are appropriate for running a Python web application on port 8080 (non-privileged port > 1024).
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if evrec_server exists in the wheel package
unzip -l dist/*.whl | grep -i "evrec_server"
# Check for any root group requirements in the codebase
rg -i "root|sudo|privileged" --type py
# Check for any port binding code that might require elevated privileges
ast-grep --pattern 'socket.bind($_)'
Length of output: 222
Script:
#!/bin/bash
# Check for the binary in common locations and setup scripts
fd evrec_server
# Look for server setup and configuration
rg -i "server|bind|listen" --type py -A 3
# Check setup.py or similar for entry points
fd "setup.py|pyproject.toml" --exec cat {}
Length of output: 1921
