Make sure to **always** use the **exec form** of the `CMD` instruction, as explained below.

///

#### Use `CMD` - Exec Form { #use-cmd-exec-form }

The <a href="https://docs.docker.com/reference/dockerfile/#cmd" class="external-link" target="_blank">`CMD`</a> Docker instruction can be written using two forms:

✅ **Exec** form:

```Dockerfile
# ✅ Do this
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```

            assertTrue("Command should contain temp path", cmd.contains(tempPath));
            assertTrue("Command should contain output path", cmd.contains(outputPath));
