How to Install Dokku on Elementary OS Latest

Dokku is a simple, lightweight platform that makes it easy to deploy and manage containerized applications on your own servers. In this tutorial, you will learn how to install Dokku on an Elementary OS Latest machine.

Prerequisites

Before you start, make sure you have the following:

• A remote machine or virtual machine running Elementary OS Latest
• SSH access to that machine with root privileges
• A domain name pointed to the IP address of the remote machine

Step 1: Update system packages

First, log in to your remote machine via SSH with root privileges:

ssh root@your_ip_address

Update the system packages to their latest versions with the following command:

apt-get update && apt-get upgrade

Step 2: Install the Dokku package

Download and install the Dokku package with the following command:

wget https://raw.githubusercontent.com/dokku/dokku/v0.27.4/bootstrap.sh

Change the permissions of the downloaded script:

chmod +x bootstrap.sh

Run the script:

./bootstrap.sh

This will install Dokku on your machine and will also create a new user called dokku.

Step 3: Configure Dokku

To configure Dokku, navigate to your remote machine's IP address or domain name in your web browser:

http://your_ip_address/

Follow the prompts to set up your Dokku server, including setting an administrator email and SSH key.

Step 4: Deploy your Application

To deploy your application, first create a new git remote. Replace myapp with your application name and your_domain_name with your domain name:

git remote add dokku dokku@your_domain_name:myapp

Make sure your application contains a Dockerfile and a Procfile to define its build and runtime configurations respectively.

Deploy your application by pushing to Dokku:

git push dokku master

Once your application has been deployed, navigate to your domain name in your web browser to view it:

http://your_domain_name/

Congratulations, you have successfully installed and deployed your application on Dokku!
