您如何在AWS Elastic Beanstalk应用程序上调用db:seed? [英] How do you call db:seed on AWS Elastic Beanstalk apps?

问题描述

我知道您可以在每次部署中运行任务，但是我只想引导数据库一次.

I know that you can run tasks as part of each deploy, but I only want to bootstrap the database once.

推荐答案

克里斯蒂安的答案很接近，但您还应该添加:

Kristian's answer is close, but you should also add:

container_commands:
  seeddb:
    command: 'export HOME=/root; rake db:seed'
    leader_only: true

因此，仅从1个EC2实例播种该数据库，而不是同时从所有它们播种.根据您的EB部署/版本，可能需要或可能不需要export HOME.

So that the DB is only seeded from 1 EC2 instance, rather than all of them at the same time. Depending on your EB deployment/version, the export HOME may or may not be needed.
