The Dockerfile had an incorrect CMD path that caused the container to fail with 'stat ./normogen-backend: no such file or directory'. The binary was being copied to /usr/local/bin/ but the CMD was trying to execute it from the current working directory. This fix changes the CMD to use the absolute path which resolves the issue.
