A container transitions through distinct states during its life:
1. **Created**: Layer allocated, network assigned, not yet started.
2. **Running**: Process actively executing inside container.
3. **Stopped / Exited**: Main process has exited or received SIGTERM/SIGKILL.
4. **Removed**: Container and its writable layer completely deleted.
