[RAILS] How to deploy

Keep a note of how to deploy.

Proceed with the prerequisite that your app has been merged into master on GitHub.

First, use a service called Heroku Heroku new registration page https://signup.heroku.com/login

If you enter the required items here, you will receive an email, so enter it and enter the following! * Enter at least 8 characters including alphanumeric characters, numbers, and symbols.

Registration is complete when something like this comes out ⬇︎

When the screen below appears, click "Accept" at the bottom of the screen ⬇︎

If you can go to the top screen of Heroku, k⬇︎

Heroku notes

Credit card registration is required to use MySQL on Heroku, so register your card information from Billing on the account management page.

Credit card registration

Follow the screenshot steps below

Enter your credit card information

Registration is complete when the screen below appears!

Install Heroku CLI

Please change to the directory you want to upload to Heroku before installing. This time I will explain in the procedure to upload the project directory

Terminal

%  brew tap heroku/brew && brew install heroku

Heroku version confirmation command ↓

% heroku --version

heroku/7.40.0 darwin-x64 node-v12.16.2 #If such a guy comes out, k

#Command to log in to Heroku
% heroku login --interactive
  => Enter your Heroku credentials.
#Enter your email address and press enter
  => Email:
#Enter your password and press enter
  => Password:

Heroku create command

%heroku create app name

Command to check if it was done properly ⬇︎

% git config --list | grep heroku

If anything other than fatal: not in a git directory is displayed, proceed to the next step.

Add ClearDB add-on

% heroku addons:add cleardb

Change settings

I added an add-on, but I haven't set it yet, so execute the following command

% heroku_cleardb=`heroku config:get CLEARDB_DATABASE_URL`

You have now stored the URL of your ClearDB database in the variable heroku_cleardb.

% heroku config:set DATABASE_URL=mysql2${heroku_cleardb:5}

You have now reset the database URL. AjaxApp uses a gem called mysql2, so make sure that the beginning of the DATABASE_URL has been changed to mysql2: //.

Check the contents of credentials.yml.enc

Terminal

% EDITOR="vi" bin/rails credentials:edit

If you see a screen like the one below After confirming, enter "esc key"-> ":"-> "q" and press "enter key" to close credentials.yml.enc.

Environment variable settings

heroku config command

It is used to refer to, add, and delete environment variables on Heroku. To add an environment variable, run heroku config: set environment variable name = "value" . By doing so, you can add environment variables on Heroku.

Execute the following command in the terminal

Terminal

% heroku config:set RAILS_MASTER_KEY=`cat config/master.key`

% heroku config

If it looks like the following

Push application

Terminal

% heroku stack:set heroku-18 -a application name

Terminal

% git push heroku master

If the push is successful, execute the migration with the following command

Terminal

% heroku run rails db:migrate

Confirmation of publication

Terminal

% heroku apps:info

After executing with the above command, in that item Web URL: https: // .... App URL

Because there is, it becomes the URL published on the WEB

If you access the URL and get an error (sweat

Run the following command to get a hint

Terminal

% heroku logs --tail --app app name

You can also check with the "heroku logs app name" command, but by using the "--tail" option, only the latest 10 lines of logs will be displayed.

No commentary required! Nah, a summary of only the commands for impatient
