How to Custom Set Up a Ruby on Rails Development Using Docker


Ruby on Rails is a web development environment much like ASP.Net in .Net framework. It not only makes web development easier, it can also be used for developing mobile apps. Docker, on the other hand, is an open source tool by ruby on rails developers that helps its users to easily create, deploy, and run applications by using containers. Containers are able to package allow a developer to package an application along with all its components such as libraries and other dependencies, and distribute it as a single application.



Advancement of Ruby on Rails Development:

  • Time efficient
  • Rapid development
  • Bug-free development
  • Secure development

To work with Ruby on Rails, it is essential to have the environment for it which can be easily setup using Docker. The advantage of using Docker is that we might not be having anything on our system when installing Ruby with Docker, and when we uninstall, we don’t need to keep track of any files that might remain. In case you have multiple projects for which you need different versions of the same service, Docker is the perfect choice. Docker can help you save on time as well. What earlier would have taken hours, can now be accomplished in minutes using Docker.

How ruby on rails is different from other web frameworks and programming languages?

Rails is a framework by which ruby on rails developers learn ruby language for website development and it is important for technical person but what are the factors that make RoR different from others?

The major characteristics of RoR is that it is an object-oriented programming language that lets ruby on rails developers to develop virtual objects for performing actions.

Installing Docker

The first step to begin with is installing Docker itself. Depending on how Docker has been installed, it is very likely that you may also require to install Docker Compose. This session assumes that you are using Ubuntu Linux. To install Docker follow the steps below:

Login to the Ubuntu server
1. Use the command sudo apt-get install docker.io –y
After the completion of the installation, add your user to the docker group by following the command below:
usermod -aG docker $USER
2. Log out of the current user, and login again

Installing Ruby on Rails
First of all issue the commands below in the same sequence, and I will elaborate on them one by one

mkdir –p ~/rails
cd /~/rails
docker run --rm -v ${PWD}:/usr/src -w /usr/src -ti ruby:alpine sh ; cd app


The commands above first create a directory called rails in the current user, and makes rails the current directory. Next it sets up a temporary container, based on ruby:alpine image, and mounts the host directory /usr/local inside that container. Next we need to deploy any dependencies that Ruby on Rails might be having. This can be accomplished with:


apk add build-base

Now we come to the main task of installing Ruby. Issue the command below to do so:
gem install -N rails

This command will take some time installing Rails, so you need to have some patience. Rails installed, you can go about generating your first ever Rails project. Issue the command:

Rails new app –database=mysql –skip-bundle


The above command instructs Ruby on Rails to start a new project titled app and having a MySQL database. Once you have completed generating the project, terminate your session and exit from the container using the exit command. This takes the user to the ~/rails/app directory. The user can start building on this recently generated project by adding more files to it. However, the directory is not owned by the current user but by the root user. To take ownership of this directory issues the following command:

sudo chown -R $USER:$USER ~/rails/app

Working with Docker Compose

Users of Ruby on Rails would most certainly also want to work with Docker Compose. Docker Compose facilitates its user by providing them with multi-container docker application. An application’s services can be configured using a YAML file. Thereafter with a single command, the user is able to create as well as start services from this configuration. To use Docker Compose you would need to install docker –ce. Follow the steps below to install docker compose:
●Add the required key using the curl command as shown:
#Curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
● Next, you need to add the repository with the following command:
#sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
● Finally install docker –ce with the command:
#sudo apt install -y docker-ce

Once the installation is complete, you are ready to start working with docker by start and then enabling it in the following manner:

#sudo systemctl start docker
#sudo systemctl enable docker


Now, download the binary file for the docker compose in the following manner:

#sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

To use docker compose, you need to provide it executable permissions. This can be done in the following manner:

#sudo chmod +x /usr/local/bin/docker-compose

You are all set to go and work with projects in Ruby on Rails
