The IP must be inside the configured subnet AND not already in use; a conflict or out-of-range value causes a start/validation error.
To use a static IP the service MUST be attached to a network that defines the matching IPAM subnet — the implicit default network has no subnet declared.
Swarm/`docker stack deploy` does not support per-service static IPv4 the same way as local Compose.
If the subnet overlaps an existing Docker bridge or host network, container bring-up can fail with an address-in-use error.
