Build a NAS with DLNA function at the speed of a second with Raspberry Pi and Docker Compose

What i did

I set up a NAS on the LAN using Raspberry Pi 3 and a USB HDD.

I used to do the same thing without using Docker, but as I was playing with adding and removing various functions to the Raspberry Pi, I began to worry that the environment became dirty. So I decided to rebuild the environment from scratch with the upgrade to Raspbian Buster and manage it with Docker Compose.

merit

• Since the environment is not polluted, other services can be freely set up and turned off.
• It is no longer necessary to take a dump (8GB) of the SD card when backing up the Raspberry Pi itself (because it can be restored from docker-compose.yml at a speed of 1 second even if it is traversed)

Preparation

• Set up Raspbian and make it ready for commands
• sudo apt update sudo apt full-upgrade
• Set the external hard disk to mount automatically at boot time (this time it was mounted to / mnt / hdd1)
• Introduce Docker Compose

Launch service

1. Use the following docker-compose to docker-compose up -d
2. Make sure you can access \\ [Raspberry Pi name] \ share from the network
3. Insert the video file you want to play with DLNA into \\ [Raspberry Pi name] \ share \ media
4. End

docker-compose.yml

version: '3.4'

services:
  minidlna:
    image: cytomich/rpi-docker-minidlna
    container_name: minidlna
    volumes:
      - /mnt/hdd1/media:/media:z
    environment:
      - MINIDLNA_MEDIA_DIR=/media
      - MINIDLNA_PORT=8200
      - MINIDLNA_FRIENDLY_NAME=NASpi
    network_mode: "host"
    restart: always
      
  samba:
    image: dperson/samba
    container_name: samba
    networks:
      - default
    ports:
      - "137:137/udp"
      - "138:138/udp"
      - "139:139/tcp"
      - "445:445/tcp"
    read_only: true
    tmpfs:
      - /tmp
    restart: always
    stdin_open: true
    tty: true
    volumes:
      - /mnt/hdd1:/mnt/share:z
    command: '-s share;/mnt/share;yes;no;yes'

result

Performance is good. As for the DLNA function, I could play it without any problem if it was about MP4 of several hundred kbps. Since it is a Raspberry Pi, overconfidence is prohibited, but it seems that there is a little more room.

Customize docker-compose.yml to create your own strongest home server!
