Accepted Answer

Docker ya ba da jerin **jerin aiki** (bridge, host, overlay, macvlan, babu) don buƙatu daban-dabanin haɗi, tare da fasaloni kamar **jerin da mai sanya ya fara** tare da gane aiki ta gida.

BRIDGE (default) → a private internal network on a single host; containers communicate;
  isolated from the host except via published ports. USER-DEFINED bridges add DNS
  (containers reach each other by name) — preferred over the default bridge.
HOST → the container uses the host's network stack directly (no isolation, no port
  mapping needed) — max performance, less isolation.
OVERLAY → spans MULTIPLE hosts → containers on different machines communicate
  (for Docker Swarm / multi-host clusters).
MACVLAN → gives a container its own MAC/IP on the physical network (appears as a
  physical device).
NONE → no networking (fully isolated).
```Jerin da mai sanya ya fara da gane aiki ta gida```bash
docker network create app-net
docker run -d --name db --network app-net postgres
docker run -d --name api --network app-net myapi
# → on a user-defined network, Docker's embedded DNS resolves container NAMES
#   the "api" reaches the database at hostname "db" → automatic service discovery

→ Containers can be placed on DIFFERENT networks to isolate them (segmentation):
  e.g. a frontend network and a backend network; only certain containers bridge both
→ Improves security (a container only reaches what it's networked with)
→ Published ports (-p) are the controlled boundary to the outside world
