Setting up Spree on Dokku via Digital Ocean

gistfile1.txt

Spree API Server Needs
- Easy Setup & Deployment (Dokku)
- New Relic
- Error Monitoring (Raven)
- Performance Monitoring (Skylight)
- Logging (Loggly or Logentries?)
- SSL (Dokku handles this)
- Database Backups (http://donpottinger.net/blog/2014/11/22/bye-bye-heroku-hello-dokku-part-2.html (See Clockwork section))
- Caching (Memcached + Dalli)
- Worker (Sidekiq)
- AWS S3 Storage
- SMTP Mailing (Mandrill)

Prerequisites:
Domain
Digital Ocean Account
Spree Dokku

1. Login to Digital Ocean
2. Setup a new Droplet with 
  - at least 2GB of Memory (Otherwise you'll get build problems)
  - IPv6 disabled
  - your Local SSH Key
  
3. Ensure you add your SSH Key to the Droplet
4. Setup DNS To point to your Dokku IP
5. Navigate to your Dokku IP in Browser and Setup the Installer
6. SSH in & install Postgres

ssh root@[droplet ip]
cd /var/lib/dokku/plugins
git clone https://github.com/Kloadut/dokku-pg-plugin.git postgresql
dokku plugins-install

7. Exit SSH
8. git remote add dokku dokku@[droplet ip]:[app-name]
9. git push dokku master
10. Precompile should fail
11. Setup a Database for the app

ssh root@[droplet ip]
dokku postgresql:create [app-name]
dokku postgresql:link app-name app-name

12. Exit SSG
13. git push dokku master
14. App Deployed!
15. Install Spree

ssh root@[droplet ip]
dokku run spree rake db:migrate
dokku run spree rake db:seed

optional:

dokku run spree rake spree_sample:load

16. Setup SMTP Environment Variables:

dokku config:set [app name] SMTP_ADDRESS=smtp.mandrillapp.com SMTP_PORT=587 SMTP_DOMAIN=[app domain] SMTP_USERNAME=[mandrill user name] SMTP_PASSWORD=[mandrill api key] [email protected]

Continuous Delivery:

From Local Machine:
- ssh-keygen -t rsa
(leave passphrase blank)
cat ~/.ssh/id_rsa_circleci.pub | ssh root@[droplet ip] "sudo sshcommand acl-add dokku circleci"

cat ~/.ssh/id_rsa_circleci
Copy on-screen output (including ----BEGIN etc---- and ----END etc---- tags
Paste into CI (circle CI: https://circleci.com/gh/{{github org}}/{{github repo}}/edit#ssh
- hostname
Paste hostname as key hostname

Now, assuming your apps are named appropriately, you can do:
(in circle.yml)

deployment: 
  staging:
    branch: staging
    commands:
      - git remote add staging dokku@[droplet ip]:staging
      - git push staging staging:master


Testing Redis
redis-cli -h [app url] -p [public port] ping

CORS on S3 Bucket
Change
<AllowedOrigin>*</AllowedOrigin>
to:
<AllowedOrigin>http://*</AllowedOrigin>
<AllowedOrigin>https://*</AllowedOrigin>

Deploying DOKKU to Root
dokku domains:add production mydomain.com

### SSL

Generate a CSR (certificate signing request - from root#home in Dokku)

openssl req -new -newkey rsa:2048 -nodes -keyout [domain-name].key -out [domain-name].csr
