deployment - 为什么在部署时抛出“需要设置 ENV 变量‘S3_KEY’”？

Answer 1

There's no need to run heroku config:add manually. Just run heroku_san's config task:

$ rake all heroku:config

Repeat this whenever you update the heroku.yml file.

I was confused about this too, since it's strangely absent from heroku_san's documentation, but the option does appear in the list of rake tasks:

$ rake -T

and in the heroku_san code: https://github.com/fastestforward/heroku_san/blob/master/lib/heroku_san/tasks.rb

Answer 2

A simple solution/work-around:

heroku config:add S3_KEY=XXX S3_SECRET=XXX --app app-staging

Any better ideas?

Answer 3

I think you need to run the command rake all heroku:rack_env. This command will then set the environment configurations for you based on your heroku_san YAML configuration.
