Simple rails template for general project.


  • Rails 6.0.x
  • PostgreSQL


To generate a Rails application using this template, pass the -m option to rails new, like this:

rails new project -T -d postgresql \

Remember that options must go after the name of the application. The only database supported by this template is postgresql.

  • Docker for production deploy
  • Nginx Proxy server configuration with Let's encrypt SSL Certificate
  • Webpacker and Stimulus setting for client javascript
  • ActiveJob + Sidekiq + Redis setting for async jobs
  • Foreman setting for integrative dev setup

Procfile-based applications

with rails hot

  • webpacker
  • guard
  • sidekiq

Stimulus generator

Stimulus specific generator task.

After installing docker & docker-compose in your host machine.

Set up a seperate Nginx-Proxy docker container in your host machine. link

git clone
cd docker-compose-letsencrypt-nginx-proxy-companion
mv .env.sample .env

Clone your repository to host machine and build docker-compose.

git clone
docker-compose build
docker-compose up -d

Scale your rails application to 5 replicas.

docker-compose up -d --scale app=5

Automated deploy task

After pushing repository to git and providing deployment information in lib/tasks/deploy.rake file. You can automate above process.

rails deploy:production


rspec-rails factory-bot

Run test specs

bundle exec rspec

scale docker containers

Docker CMDs

To see your live container log

docker ps
docker log -f processid

Check images / containers

docker images -a
docker container ls -a

Remove all abandonded images

docker rmi -f $(docker images -a | grep "none" | awk '{print $3}')

Destry all exited containers remove scientist name containers

docker container rm $(docker container ls -aq --filter status=exited)

Prune (be careful)

docker container prune
docker image prune
docker network prune
docker volume prune

Stop and delete specific container

docker stop processid
docker rm processid
You can’t perform that action at this time.
