问题
So here what I did and the following output:
root@ubuntu-512mb-sfo1-01:/var/lib/dokku/plugins# dokku postgres:link DATABASE ubuntu-512mb-sfo1-01
2016/02/18 05:24:38 open /var/lib/dokku/plugins/available/pg-plugin/plugin.toml: no such file or directory
2016/02/18 05:24:38 open /var/lib/dokku/plugins/available/pg-plugin/plugin.toml: no such file or directory
no config vars for ubuntu-512mb-sfo1-01
Can someone help me? I try to deploy rails to digital ocean. I use http://blog.flatironschool.com/using-digital-ocean-and-dokku-for-easier-rails-app-deploys/ - this tutorial but it seems to be horribly outdated. I ran into so many errors so I am thinking of giving this up and staying with heroku hosting.
回答1:
It means that you don't have a Postgres docker container active. Take a look at the dokku-pg-pluging to know how to configure and instantiate a postgres docker container.
By the way, since your objective is to change from Heroku to DigitalOcean, and you're having trouble using dokku, may I suggest you using deploy bot instead? I did managed to successfully deploy an rails 4 app to DigitalOcean using deploy bot. Follow this tutorial. And you can easily follow this guide with deploy bot, adapting the unicorn and nginx stop/start services with the hooks that deploy bot provides.
Edit: Since you wanted a more specific answer for the deploy bot solution, here goes my approach (this was +/- 3/4 months ago):
Create the droplet and follow the guide to create a droplet, install ruby, rails, unicorn and nginx and the script to control unicorn (it's in the tutorial).
Configure the deploy bot and make sure you run
bundle installand another rails' specific commands (changing environments and so on) after the upload (this is a predefined hook).The last command should be
service nginx restartto restart the server (using the script from step 1).Profit!
