seafile のインストールに成功しましたが、複数のサービスをホストしたいので、それをリバース プロキシの背後に配置したいと考えています。ただし、nginx から「Bad Gateway」が表示され、何が問題なのかわかりません。

これは作業中の seafile docker-compose.yml です (リバース プロキシなし):

version: '2.0'
services:
  db:
    image: mariadb:10.1
    container_name: seafile-mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_LOG_CONSOLE=true
    volumes:
      - /home/docker-seafile/seafile-mysql/db:/var/lib/mysql
    networks:
      - seafile-net
  memcached:
    image: memcached:1.5.6
    container_name: seafile-memcached
    entrypoint: memcached -m 256
    networks:
      - seafile-net
  seafile:
    image: seafileltd/seafile-mc:latest
    container_name: seafile
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /home/docker-seafile/seafile-data:/shared
    environment:
      - DB_HOST=db
      - DB_ROOT_PASSWD=password
      - TIME_ZONE=Europe/Zurich
      - SEAFILE_ADMIN_EMAIL=info@domain.com
      - SEAFILE_ADMIN_PASSWORD=password
      - SEAFILE_SERVER_LETSENCRYPT=true
      - SEAFILE_SERVER_HOSTNAME=seafile.domain.com
    depends_on:
      - db
      - memcached
    networks:
      - seafile-net
networks:
  seafile-net:

これは、letsencrypt コンパニオンを使用した jwilder/proxy の docker-compose.yml です。

version: '2'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"

    restart: always
  letsencrypt:
    image: jrcs/letsencrypt-nginx-proxy-companion
    container_name: nginx-proxy-le
    depends_on:

    volumes_from:
      - nginx-proxy
    volumes:
      - /home/docker-nginx-proxy/certs:/etc/nginx/certs
      - /var/run/docker.sock:/var/run/docker.sock:ro
    restart: always
networks:
  default:
    external:
      name: nginx-proxy

これは、リバース プロキシの背後にある seafile 用に変更された docker-compose.yml です。

services:
  db:
    image: mariadb:10.1
    container_name: seafile-mysql

  memcached:

    container_name: seafile-memcached
    entrypoint: memcached -m 256
    networks:
      - seafile-net
  seafile:
    image: seafileltd/seafile-mc:latest
    container_name: seafile
    ports:
      - "3000:80"
    volumes:
      - /home/docker-seafile/seafile-data:/shared # Requested, specifies the path to Seafile data persistent store.
    environment:
      - DB_HOST=db
      - DB_ROOT_PASSWD=password

      - SEAFILE_ADMIN_EMAIL=info@domain.com
      - SEAFILE_ADMIN_PASSWORD=password
      - VIRTUAL_HOST=seafile.domain.com
      - VIRTUAL_NETWORK=nginx-proxy
      - VIRTUAL_PORT=3000
      - LETSENCRYPT_HOST=seafile.domain.com
      - LETSENCRYPT_EMAIL=info@domain.com
    depends_on:
      - db
      - memcached
    networks:
      - seafile-net
      - nginx-proxy
networks:
  seafile-net:
  nginx-proxy:
    external: true

何が間違っているのでしょうか？

http://seafile.domain.comへの proxy_passが間違っているように見えますか、それとも間違っていますか?

jwilder によるネットワークの問題の解決策は client_max_body_size です。設定がないので、最大アップロードは 1M です。

プロキシコンテナの docker-compose.yml に新しいファイルと新しい行を追加することで解決しました。完全な説明については、こちらをご覧ください。

[https://github.com/strahli30/HowTo-use-Docker-Seafile-Plex-NGINX][1]

要するに：

  • 新しいフォルダを作成するmkdir nginx.template

  • 新しいファイルを作成するsudo nano nginx.template/client_max_body_size.conf

  • このファイルの 1 行:client_max_body_size 0;

  • jwilder/nginx-proxy:alpine の docker-compose.yml のボリュームで、この行: ./nginx.template/client_max_body_size.conf:/etc/nginx/conf.d/client_max_body_size.conf:ro

Seafile と Nginx を再起動すると、すべて正常に動作します。:-)
