Executing scripts from the Internet can be dangerous! Check the source before using!

What Is That?

Rails App in a Docker container with some popular preinstalled tools.

Why Do I Need It?

Save hours, days or weeks on setting up a typical Rails app.

What Cases for Using It?

You start new Rails project
You need a playground for experiments
You learn Rails and related technologies
You teach people or record videos about Rails
You are going to write a new article about Rails

Conventions and Agreements

Show details

For demonstration, education and maintainance purposes I use a bit unsusual approach to name some files.

I _UNDERSCORE and UPPERCASE some files and folders to move them on the top of a folder and to make them more visible and to highlight their importance.

Data

All services' data related folders are placed in ./db
All folders are UPPERCASED

./db
├── ELASTIC
├── PGSQL
└── REDIS

Configuration Files

All services' configurations are placed in ./config
All configs are _UNDERSCORED and UPPERCASED

./config
├── _CONFIG.yml
├── _PUMA.rb
└── _SIDEKIQ.yml

Initialazers

All services' initializers are placed in ./config/initializers
All files are _UNDERSCORED and UPPERCASED

./config/initializers/
├── _CHEWY.rb
├── _CONFIG.rb
├── _REDIS.rb
└── _SIDEKIQ.rb

Rails user

Show Details

As a user to own files and run Rails inside a container I use

user:group => lucky:lucky => 7777:7777

If you would like to run the project on a linux environment then:

create group lucky (7777) and user lucky (7777)
run the project with RUN_AS=7777:7777 option

Questions and Answers

What is an idea of this project?

For many years Rails gives you freedom to choose development tools. Different databases, different paginators, different search engines, different delayed job solutions.

It is great. But all the time you need to choose something and install it from scratch.

I think I did my choice about many solutions and tools.

I want to install my minimal pack of tools now and reuse my StartKit every time when I start a new project.

With Docker I can roll out my minimal application with all required preinstalled tools in minutes, not in hours or in days.

Why did you create this project?

I didn't work with Rails last 4 or 5 years. I wanted to learn new approaches and techniques. I found that there is still no a simple way to setup a blank app with most popular tools.

So. Why not to make my own playground?

How do you choose technologies for the StartKit?

I use tools that I like or want to learn.

I use tools that I think are the most popular ones.

It looks good for development. What about production?

I'm not a DevOps, but I have a vision how to deploy this code to production.

Right now it is not described somehow. It is in my plans.
