推薦 Portainer 方便圖形化管理

Docker Compose

若擔心 latest 會每次 pull 重新部署就弄壞的話，就自己挑選合適版本號定下來。

version: "4.5"

services:
  tsumugi-db:

    volumes:

      CLIENT_MAX_BODY_SIZE: 500M
      STAGE: 'production' # Don't use production until staging works
      # FORCE_RENEW: 'true'
    volumes: 
      - https-portal-data:/var/lib/https-portal

volumes:
  tsumugi-mariadb_data: {}

  tsumugi-wordpress_php: {}

  https-portal-data: {}

除錯

• 瀏覽器 開發者 Console 印出 413 Request entity too large
  • https-portal 需要調整環境變數 

CLIENT_MAX_BODY_SIZE: 500M

附帶一提我不小心在 500M 後面加上分號變成 \CLIENT\_MAX\_BODY\_SIZE: 500M;\ 結果容器還是運行，但是顯然網站沒有回應。
查詢 https-portal 的 error.log 會出現以下特徵錯誤訊息，我的 Volume 配置是位處 dd87****87b 資料夾

2024/07/19 13:52:01 [emerg] 59#59: unexpected ";" in /etc/nginx/nginx.conf:56

• 無法上傳大於 2MB 的檔案到 WordPress
  • 由於我的 Compose 配置已將 PHP 直接對應到 Volume，所以可以 sudo dolphin /var/lib/docker/volumes/yourstack-zundamon-wordpress_php/_data/conf.d 新增 uploads.ini 撰寫內容如下

file_uploads = On
memory_limit = 500M
upload_max_filesize = 500M
post_max_size = 500M
max_execution_time = 600
