Operating the Celery Worker in the ECS Fargate

荒凉一梦 提交于 2020-05-27 04:34:27
问题 I am working on a project using AWS ECS. I want to use Celery as a distributed task queue. Celery Worker can be build up as EC2 type, but because of the large amount of time that the instance is in the idle state, I think it would be cost-effective for AWS Fargate to run the job and quit immediately. Do you have suggestions on how to use the Celery Worker efficiently in the AWS cloud? 回答1: Fargate launch type is going to take longer to spin up than EC2 launch type, because AWS is doing all

How to set up a Docker redis container with ssl

夙愿已清 提交于 2020-05-23 11:45:51
问题 I'm following this tutorial. In my case I am operating in a Docker environment, and I have a secured site (i.e. https://localhost). which requires secured ssl communication. I adjusted the web , and celery containers for secure connection. But I don't know how to configure the Redis container for secure connection with ssl Note that when I run without ssl connection in the web and celery containers, the connection is fine. How do I configure and run redis with ssl? Thanks EDIT: I followed

JS数组常用方法---2、push方法使用及原理

JS数组常用方法---2、push方法使用及原理 一、总结 一句话总结: push方法的作用是向数组末尾添加一个或多个元素,参数是要push到数组的元素,返回值是数组新的长度,push方法会影响原数组 push方法的原理就是动态的获取传递给push方法的参数,然后依次循环遍历的加到原数组后面 push方法 作用:向数组末尾添加一个或多个元素 参数:element1, ..., elementN 返回值:数组新的长度(length) 是否影响原数组:肯定影响 // 简单实现push方法 Array.prototype.push1= function () { // 通过遍历把参数加到原数组里面去 for (let i in arguments){ this [ this .length]= arguments[i]; // 如果this是对象的话,我们就手动的对这个对象的length属性加1 if (Object.prototype.toString.call( this ).slice(8,-1)=='Object' ){ this .length++ ; } } return this .length; }; 1、调用数组方法另外的形式(除了 arr.方法名 外)? 1、Array.prototype.push.apply(vegetables, moreVegs); 2、[]

django 使用redis进行页面数据缓存和更新缓存数据

转自:https://blog.csdn.net/xiaohuoche175/article/details/89304601 在开发过程中会遇到一些页面的数据是很长时间才进行更新的,不使用缓存的情况下,用户每次访问这些都需要先去数据库中获取这些数据,当访问量较大时,这样获取数据的方式就会降低页面的访问速度,影响效率,这时就可以使用redis将这些数据保存起来,通过判断是否生成过获取以及是否更新过数据来生成新的缓存数据 具体操作如下: 在settings.py里添加缓存设置 # Django的缓存配置 CACHES = { "default": { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": "redis://127.0.0.1:6379/9", "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } } } 在对应的app中的views.py文件中写视图逻辑和缓存操作 from django.core.cache import cache from goods.models import GoodsType, GoodsSKU, IndexGoodsBanner,IndexPromotionBanner

python-django框架-电商项目-首页开发_20191122

python-django框架-电商项目-首页开发 业务背景: 用户浏览网站一定是先到首页, 没有登陆的话首页内容完全一样,而且是不经常变化的, 一段时间内,有100用户访问,就要有几个用户就要查询多少次数据库, 查出来的数据都是一样的, 怎么办? 我们把页面生成一个静态页面, 用户访问的时候,我给用户返回一个静态的页面, 可以使用我们之前讲到的celery,定义一个任务函数,生成一个静态页面, 什么时候首页的静态页面需要重新生成? 页面改动的时候就需要重新生成, 当管理员在后台修改了首页的信息,对应的表格中的数据的时候,需要重新生成我们的首页静态文件, 给celery定义个任务函数: generate_static_index_html函数 在虚拟机启动worker, 把项目代码复制到虚拟机中,可以放到桌面 进入项目路径,/home/andy/桌面/dailyfresh/,一定要在这个项目目录下面!! 进入虚拟机工作空间,workon lq_py3 启动这个任务,celery -A celery_tasks.tasks worker -l info 报错了,应该是有服务没有启动,借这个机会,我重新梳理一下celery,重新开一个博客, 启动成功了,继续, 发出celery任务 在django的console, 输入from celery_tasks.tasks import
