Depends on the application. If it's a single, stand-alone application meant to run in a bare container, sure. But many applications are more complicated, or have been shimmed into a container, but generally run on a given Linux system. Diagnostics and debugging inside the running container kind of requires some level of shell and interactivity. Alpine and Debian-slim images usually have enough for this purpose. If you can navigate the file system and list files at the very least, you can exfiltrate data as needed relatively easily though.
