Docker Setup and Debugging Guide

Development environment

After cloning the repo and installing docker on your machine, run the following command from the root directory of the project.

cp .env.example .env

Make changes to the .env file as required. [Optional]

docker-compose build

After building the image or after destroying the stack you would have to reset the database using following command

docker-compose run --rm rails bundle exec rails db:reset

Running the app

docker-compose run --rm --service-port rails

open another terminal and also run below command to run sidekiq in a separate service

docker-compose run --rm rails bundle exec sidekiq
  • Access the rails app frontend by visiting
  • Access Mailhog inbox by visiting (You will receive all emails going out of the application here)
  • Access Sidekiq Web UI by visiting (You need to login with administrator account to access sidekiq)

you can also use the below command instead to run the app and see the full logs.

docker-compose up

Destroying the complete composer stack

docker-compose down

Running rspec tests

For running the complete rspec tests

docker-compose run --rm rails bundle exec rspec

For running specific test:

docker-compose run --rm rails bundle exec rspec spec/<path-to-file>:<line-number>

production environment

Sometimes you might want to debug the production build locally. You would first need to set SECRET_KEY_BASE environment variable in your .env.example file and then run the below commands:

docker-compose -f docker-compose.production.yaml build
docker-compose -f docker-compose.production.yaml up
