Tutorial: How to Install Dokku on EndeavourOS Latest

In this tutorial, we will cover the steps required to install Dokku, a self-hosted platform-as-a-service that enables developers to build and deploy applications to their own servers. EndeavourOS Linux distribution will be used as the operating system for this tutorial.

Prerequisites

Before starting this tutorial, make sure that you have the following:

• A server or virtual machine running EndeavourOS Linux distribution.
• A user account with sudo privileges.
• A valid domain name or subdomain name pointing to the IP address of the server.

Step 1 - Updating the System

It is recommended to start by updating the system to prevent any potential conflicts or security issues. Open a terminal window and run the following command:

sudo pacman -Syyu

This will update the package database and install any available updates.

Step 2 - Installing Dependencies

Dokku requires a number of dependencies to be installed in order to run correctly. Enter the following command in the terminal window to install these dependencies:

sudo pacman -S python python-setuptools python-pip git

Step 3 - Installing Dokku

Use the following command to install Dokku:

wget https://raw.githubusercontent.com/dokku/dokku/v0.21.4/bootstrap.sh

sudo DOKKU_TAG=v0.21.4 bash bootstrap.sh

This will download the Dokku installation script from the official Dokku repository and execute it with the specified version tag.

Step 4 - Configuring Dokku

Once Dokku is installed, it needs to be configured for your environment. Dokku sets up a web interface and can be accessed through the web browser. Ensure that your domain name or subdomain name has been set up to point to the IP address of your server before proceeding.

To set up the web interface, enter the following command in the terminal:

dokku domains:add-global dokku.me

This command adds the dokku.me domain to the global configuration of Dokku domains. Replace dokku.me with your own custom domain or subdomain name.

Next, enter the following command to set up a single administrator user for the Dokku web interface:

dokku ssh-keys:add dokku admin

This command adds an SSH public key for the user admin in order to allow access to the web interface. Replace admin with your desired username if necessary.

Step 5 - Deploying an Application

With Dokku configured, we can now deploy an application. In this tutorial, we will use a simple "Hello World" Node.js application for demonstration purposes.

First, create a new directory and switch to it:

mkdir helloworld

cd helloworld

Next, create a new Node.js application:

npm init

Follow the prompts to configure the package.json file for your application. Once the configuration is complete, create an index.js file and add the following code:

const http = require('http');

const hostname = '0.0.0.0';
const port = process.env.PORT || 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, World!\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Save the file and exit the text editor.

Next, create a Git repository for the application:

git init

git add .

git commit -m "Initial commit"

Finally, deploy the application to Dokku:

git remote add dokku [email protected]:helloworld

git push dokku master

This will push the application code to Dokku and deploy it as a new application. Once the deployment is complete, the application can be accessed at http://helloworld.dokku.me.

Conclusion

Dokku provides an easy-to-use platform-as-a-service solution for self-hosting applications. By following the steps outlined in this tutorial, you should now have a fully functioning Dokku installation on your EndeavourOS Linux server, along with a deployed Node.js application.
