Dokku is a Platform as a Service (PaaS) software that allows developers to easily deploy, manage and scale their applications. It is an open-source software that is designed to work with a variety of programming languages like Ruby, Node.js, PHP, Python, and more.
In this tutorial, we will see how to install Dokku on POP! OS Latest. Before proceeding further, make sure you have a server with POP! OS Latest installed and root access to it.
Before installing any software, it is always a good practice to update the system to the latest version. To do so, run the following commands:
sudo apt update
sudo apt upgrade
To install Dokku on your server, you can use the official script provided by Dokku. To do so, run the following commands:
wget https://raw.githubusercontent.com/dokku/dokku/v0.23.3/bootstrap.sh
sudo DOKKU_TAG=v0.23.3 bash bootstrap.sh
The first command will download the installation script, and the second command will start the installation process. During the installation process, you will be asked to enter a domain name for your Dokku installation. Enter the domain name that you have pointed to your server.
Once the installation process is complete, you can configure Dokku by setting up an SSH key for the dokku user. The SSH key is used to authenticate with the Dokku server.
To set up an SSH key, run the following command:
cat ~/.ssh/id_rsa.pub | ssh dokku@your_domain_name.com "sudo sshcommand acl-add dokku $(cat)"
Replace your_domain_name.com with your actual domain name.
Now that you have installed and configured Dokku on your server, you can deploy your application. To deploy your application, you need to create a Git repository for your application and push it to the Dokku server.
To create a Git repository, run the following commands:
mkdir myapp
cd myapp
git init
Now, create an index.html file in the myapp directory and commit the changes to the Git repository:
echo "Hello, World!" > index.html
git add index.html
git commit -m "Initial commit"
To deploy your application to Dokku, you need to add the remote server and push your changes to it:
git remote add dokku dokku@your_domain_name.com:myapp
git push dokku master
Replace myapp with the name of your application.
Congratulations! You have successfully installed and configured Dokku on POP! OS Latest, and deployed your first application. Dokku is a powerful tool that allows you to easily manage and scale your applications. With its simple interface and easy-to-use commands, you can focus on coding and leave the deployment and management to Dokku.
