Rake db: migrate working on AWS Beanstalk development

I am new to Beanstalk. I created a Rails application and set up a database production configuration to use the environment variables that we hope AWS provided. I use Mysql (mysql2 gem) and want to use RDS and Passenger (I have no preferences there).

In my development environment, I can run the rails application using my local Mysql (this is just the base application I created for experimenting). I added a gem to the Gemfile and bundled, but I still use WEBBrick in development.

The only thing I did not do in the book was that I did not use "eb", but rather tried from the console. My application / environment failed to start while "rake db: migrate" still thinks I want it to connect to the local Mysql (I think from the logs that it does not know RACK_ENV and therefore uses "development") .

What advice? I can, of course, try the following "eb", but would prefer to work with the console.

Regards, Oren

You tried to run

bin/rake db:migrate RAILS_ENV=development

? I have the same problem and it worked for me.

In Elastic Beanstalk (both in the web console and in cli) you can pass environment variables. If you pass the variable RAKE_ENV , you will change your environment.

After that, you still need to pass the parameters of your database (db password, name, ...), which should not be hardcoded in the code.

I recommend that you enter an EC2 instance using this " eb ssh " command (the first time you need to specify a .pem file, if you don’t have one, you can create IAM services ) and check your logs for more information about your error.

If you have problems downloading the code (eb deploy), you have a log in this file: " /var/log/eb-activity.log " (remember that this file is located in your EC2 instance)

If you have problems with your application, you can read the logs in these files: " /var/app/support/logs/production.log " or " /var/application/support/logs/passenger.log "

Other recommendations are to install EB CLI version 3. to manage your eb instance

I thought Elastic Beanstalk would run "rake db: migrate" on its own. Actually, this seems to be an attempt, but it fails. I gave my Yahs Hef award, although I will only try in the evening (UK). My disorientation with AWS made me forget this simple solution, migrate on my own. If this does not work on its own, I will simplify setting up the database whenever possible.
