heroku

问题 I have an application that uses postgres in development and production. I recently pushed to heroku and everything was working fine. I was able to pull the database from heroku and push back up with no problem. Today however, I tried to pull the DB down from heroku and I received this error heroku db:pull Loaded Taps v0.3.24 Auto-detected local database: postgres://postgres:a@127.0.0.1/app_development?encoding=utf8 Warning: Data in the database 'postgres://postgres:a@127.0.0.1/app_development

问题 I have a simple Procfile that reads: web: bundle exec rails server thin -p $PORT worker: bundle exec rake jobs:work On Heroku, this will launch N worker tasks, where N is whatever I've scaled it to be. On my development system, $ foreman start will only launch one worker task. If I want to launch three workers, I need a Procfile that looks like: web: bundle exec rails server thin -p $PORT worker: bundle exec rake jobs:work worker: bundle exec rake jobs:work worker: bundle exec rake jobs:work

问题 I'm using LoopBack ver. 1.6 and have a local mongoDB server running for development using he following datasource configuration: "mongodb": { "defaultForType": "mongodb", "connector": "loopback-connector-mongodb", "database": "xxxdbname", "host": "localhost", "port": "27017" }, Now I want to deploy to Heroku but I don't know how to configure the datasource to point at the MongoLab db since it has a dynamically generated connection string: from the Heroku dox: var mongo = require('mongodb');

问题 I'm looking into using Heroku for a PHP app that uses Redis. I've seen the various addons for redis. With Redis To Go, for example, you can use an environment variable $_ENV['REDISTOGO_URL'] in your PHP code, as the URL of the Redis Server. Most of these add ons have their own pricing schemes which I'd like to avoid. I'm a little confused about how heroku works. Is there a way that I can just install Redis on my own Dynos without the addons? Like for example, have one worker dyno that acts as
