Hi to all

I searched about communication by name from container in same docker compose but I couldn’t find anything :frowning:

i have a docker-compose with a mariadb container and a simple debian server:

version: "3"

services:
  db:
    image: linuxserver/mariadb:10.11.4
    container_name: testsrv-db
    environment:
      - PUID=1000
      - PGID=1000
      - MYSQL_ROOT_PASSWORD=rootpass
      - TZ=Europe/Rome
    volumes:
      - ./data:/config
    restart: unless-stopped
  testsrv:
    image: test/testsrv
    container_name: testsrv
    hostname: testsrv
    network_mode: host
    depends_on:
      - db
    restart: unless-stopped

how can i reach db from testsrv container with ping to db name?

thanks in advance

Because of this, you can’t. Container with network_mode: host can not reach containers in bridge networks.
