可以在不使用Heroku Toolbelt的情况下部署Rails应用程序吗？ 如果是这样，怎么样？

Question

I want to deploy rails app without using Heroku ToolBelt. Is it possible? If so, how? I'm only allowed to use Heroku dashboard; I'm not allowed to use any other cloud service :(

I have to run PostgreSQL commands, adding add-ons and setting configuration variables and possibly other tasks for which we have Heroku Toolbelt to deploy a application in production environment.

Error:

user@xx ~/Desktop/github/blog (master)
$ git push git@heroku.com:herokugui.git master
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I don't want to use Heroku Toolbelt. That's why I am using Git commands to deploy code on Heroku. I am not able to push code to Heroku using Git commands. Is it possible to do this task without the toolbelt?

Another question I have is: is there any way to run PostgreSQL commands on Heroku GUI? If so, how?

Answer 1

It's not easy (as with Heroku toolbelt), but it's possible. It involves hanging around your Heroku dashboard at least, so make sure you can access it.

First off, you need a key. If you're on a Linux machine (as me), then in your home directory you should have a folder named .ssh (it may be hidden, hit Ctrl+H to reveal, again, if Linux) and a file id_rsa.pub in there. If not, you need to generate your SSH key first.

ssh-keygen -t rsa

That will prompt you for a folder, default is fine, just hit Enter , then enter the passphrase (twice) to protect your key from being accessed by anyone else on your computer: without a passphrase it's unencrypted and free for anyone to take and use from that machine.

Once that is done, locate your public key file: id_rsa.pub . Note : not id_rsa , it's a private key, you may not want to give it to anyone, it's much like your future Heroku password, except for it's insanely large for a password. Open id_rsa.pub , you should see stuff like:

ssh-rsa aWhOLELotofUnreadABLEGibbERishWHiCHiSactUALLyYourPubLIcKeY...

You need to enter that line into your account settings in Heroku dashboard, under SSH Keys . You can find more info on keys here, in Heroku docs . Make sure Heroku actually recognizes you by issuing this:

ssh -v git@heroku.com

It should state you're authenticated.

Now for the git address. I assume you know your way around git , so I'll keep it short: you'll need to derive your repository address from your app name. Heroku usually generates weird (yet somewhat poetic) names like falling-wind-1624 or shielded-fjord-1858 . I'll take the first one as an example, this is how you add its address as a git remote:

git remote add heroku git@heroku.com:falling-wind-1624.git

I'll explain a bit of it below. So what the toolbelt does here, is to use your app name only, it just builds the URL the same way by adding a path to Heroku server. Once that's done, you should be able to push your code:

git push heroku master

I've named a Heroku remote heroku , above, that's why I'm using heroku name here, you can name it whatever you want and use this afterwards. Once you've pushed the code, the rest is up to you.
