Yes, a shipping container can have receptacles and a breaker panel. The installation should be designed and completed under the electrical rules that apply where the container will sit, using approved equipment and an authorized electrical contractor where required. The designer must know the supply, voltage, connected loads, environmental exposure, metal enclosure, future relocation plan and whether the space is storage or occupied before selecting the panel and circuits.
A container breaker panel begins at the supply
Map container outlets to equipment, not equal spacing
Ask how the metal enclosure affects grounding and bonding
Protect the panel and wiring from storage operations
Relocation changes the connection question
Use the authority for the actual province
Handover should prove more than energization
Turn the equipment list into a one-line design
Provide the source, distance, voltage and every connected load. Ask the electrical quote to identify service, panel, circuits, receptacles, bonding, protected wiring, permits, tests and closeout documents.
