How to install Staytus with Dokku

[cbldev]

Hello,

Today, I did a fresh deployment of Staytus with Dokku, an open-source small PaaS implementation.
I faced some difficulties, here a small documentation on how to built it on Dokku.

1. I installed Dokku on a fresh server with PostgreSQL and Let's Encrypt plugins for SSL support.

2. I switched the application to PostgreSQL :

• I did configuration for a new config/database.yml file
• I removed config/database.yml from .gitignore
• I removed the mysql gem from Gemfile
• I added the pg gem to Gemfile
• I changed the db/schema.rb file by removing the options on all tables, as these options are for MySQL only

3. I removed the Dockerfile from the repository.

4. I created the Dokku application, database and linked them.

5. I configured these environments variables for the application on the Dokku server :

• FORCE_SSL
• SECRET_KEY_BASE
• STAYTUS_DEMO
• STAYTUS_SMTP_HOSTNAME
• STAYTUS_SMTP_PASSWORD
• STAYTUS_SMTP_USERNAME
• STAYTUS_THEME

6. I configured the application domain and Let's Encrypt SSL certificate with Dokku.

7. I updated the BCrypt gem to to be able to create the first admin user.

8. I pushed to my Dokku server.

9. I ran the install commands inside my container.

bundle exec rake staytus:build staytus:install

10. I enjoyed!

If some people are interested in a more complete documentation on a fork or a PR, feel free to say it there!
