ruby-on-rails - 如何在docker上将rails与postgresql连接起来？获取：无法连接到服务器：连接被拒绝

Question

我遵循了本教程：https ://thoughtbot.com/blog/rails-on-docker

当我跑...

docker-compose run web rake db:create db:setup

...我收到此错误：

could not connect to server: Connection refused
        Is the server running on host "127.0.0.1" and accepting
        TCP/IP connections on port 5432?
