nginx做為伺服器，mongo為資料庫支持，flask為python語言的web框架，利用docker的容器特性，可以簡單地部署在linux伺服器上

eofflask應用的配置

from app import create_app app = create_app('default') app.debug=false # if __name__ == '__main__': # app.run()
nginx的設定

踩坑吐槽
1 mongol容器中的初始化檔需要放在docker-entrypoint-initdb.d 目錄下
#本人做過以下嘗試，會顯示mongdb未啟動。
add setup.sh /data/setup.sh run chmod +x /data/setup.sh cmd ["/data/setup.sh"]
在資料庫的配置應相應寫成：
mongodb_settings = {
'db': 'test',
'host': 'mongo', # 127.0.0.1 host地址一定要写你配置的--link的名字
'username': 'test',
'password': 'test',
'port': 27017
}以上是如何使用Docker部署Nginx+Flask+Mongo的應用的詳細內容。更多資訊請關注PHP中文網其他相關文章！
