Docker for Ruby On Rails

This files are needed to start a Rails app though Docker, with the only condition of having installed Docker on your system.

FAQ:

• I don't want to install anything, is there any link to see the see the project?

  • There isn't a Free hosting service to house the app, because all background workers are premium features.
  • If you want to the use the app, send me an email to emanuel.rodriguez.bedeman@hotmail.com or message me though linkedin

• Do I need to install ruby on my pc?

  • No, you don't need to install ruby on your system, only Docker

• Why is this approach is recommended instead of installing ruby and all it's services?

  • Because installing Ruby on Rails usually has a lot of differents issues, specially on Windows (the OS I developed the app).

• If I already have installed Ruby On Rails 7 on my OS, can I still run the app?

  • Yes, you can. Just remember to install the same gems's versions, setup redis, sidekiq and the .env variables.
  • Keep in mind that the app wasn't made by this method, so I can't guaranteed you that it'll work.

Steps

1. Create folder on your machine.
2. Download this repo.
3. Open CLI (cmd for Windows), navigate to the created folder and enter: docker-compose-build.
4. Once is done, enter: docker-compose run --rm --service-ports ruby_dev to run the container with it's images.
5. You'll in Rail's shell, to create a new project enter:

rails new myapp && cd myapp
note: change "myapp" to the name that you want.

6. Run the server by using: rails server -p $PORT -b 0.0.0.0.
7. Enter http://localhost:3000/ in your browser to enter the app.

If you want to Run Sidekiq:

1. Open a new CLI (don't worry about the directory).
2. Type: docker ps to see all the running containers.
3. Search for the one saying "schedule tweets" and copy it's ID.
4. Enter: docker exec -it container_id bash (replace container_id for the copied ID) to enter debugging mode.
5. Once again, you'll be in Rail's shell.
6. To start the schedule tweet's jobs, enter: bundle exec sidekiq.
7. That's it! Now you'll have the app running with all it's functions and you can use / explore / modify it as you please.
