If the container image itself is flawed or built incorrectly, how would that manifest as an unhealthy status during project startup?

An incorrectly built or flawed image can lead to immediate startup failures and an unhealthy status. This might involve missing application dependencies (libraries, executables) inside the image, an incorrect `ENTRYPOINT` or `CMD` that fails to execute the application, a corrupted base image, or errors during the build process that result in an incomplete or broken image. The container logs would typically show 'command not found', application crash reports, or errors indicating missing files. To debug, rebuild the image (`docker-compose build --no-cache` or `docker build --no-cache`) and carefully review the Dockerfile for errors, ensuring all necessary build steps and dependencies are included.
