How to Create a Minimalist Kanban in Linux with Kanboard

A photography of two people holding a series of sticky notes.

Kanboard is a lightweight kanban project tracker that you can host on your own server. Unlike other kanban trackers, it aims to create a simple and intuitive interface that you can access from anywhere.

This article will show you how you can install Kanboard in Ubuntu 22.04. It will also highlight the process of extending Kanboard using community plugins.

Why Use Kanboard?

One of the biggest advantages of Kanboard is that it can work on almost any server through the magic of Docker. As a result, hosting Kanboard is both painless and easy even for non-technical users.

Aside from that, Kanboard also comes with a flexible plugins platform. This includes the ability to create tags, track time and run custom scripts. For example, you can create a plugin that updates the properties of each card depending on its content.

Installing Kanboard

  1. The first step in installing Kanboard is to make sure that your system is up to date. You can do this by running the following command:
sudo apt update
sudo apt upgrade
  1. Install the Docker project’s third-party repository key:
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker.gpg
sudo chmod a+r /etc/apt/trusted.gpg.d/docker.gpg
  1. Create a new apt repository file using your favorite text editor:
sudo nano /etc/apt/sources.list.d/docker.list
  1. Write the repository information for the official Docker repository:
deb [arch=amd64 signed-by=/etc/apt/trusted.gpg.d/docker.gpg] jammy stable
  1. Save your new repository file by pressing Ctrl + O, then Ctrl + X.
  1. Update your system’s repository details by running the following command:
sudo apt update
  1. Install Docker engine along with its dependencies using apt:
sudo apt install wget docker-ce docker-ce-cli docker-compose-plugin docker-buildx-plugin

Obtaining Kanboard

Once you have Docker engine properly installed, the next thing to do is to fetch the Docker Compose script for Kanboard. This is a small text file that contains a list of options that will tell Docker how to automatically create Kanboard.

  1. Create a separate folder in your home directory for Kanboard:
mkdir ~/kanboard
cd ~/kanboard
  1. Create a new text file with the name “docker-compose.yml” through your favorite text editor:
nano ~/kanboard/docker-compose.yml
  1. Copy the following block of code and paste it inside your “docker-compose.yml” file:
version: '2'
    image: kanboard/kanboard:latest
      - 8080:80
      - kanboard_data:/var/www/app/data
      - kanboard_plugins:/var/www/app/plugins
      DATABASE_URL: mysql://kanboard:!#REPLACE-ME@db/kanboard
    image: mariadb:latest
    command: --default-authentication-plugin=mysql_native_password
      MYSQL_DATABASE: kanboard
      MYSQL_USER: kanboard
    - db:/var/lib/mysql
  1. Open a new terminal and generate a secure password using the following command:
cat /dev/urandom | tr -dc 'A-Za-z0-9' | fold -w 16 | head -n 1
  1. Go back to your previous terminal and paste your secure password to every instance of “#!REPLACE-ME” inside the file.

  1. Save and exit your “docker-compose.yml” file by pressing Ctrl + O, then Ctrl + X.
  1. You can now build your Kanboard docker container by running the following command:
docker compose up -d

Setting Up Kanboard for SSL

At this point, you now have a partially working Kanboard installation. However, in order to access it securely, you need to first create an Nginx reverse proxy. This will serve as your web-facing server that provides load balancing and SSL.

  1. Install the Nginx webserver:
sudo apt install nginx
  1. Create a site configuration file for your Nginx reverse proxy:
sudo nano /etc/nginx/sites-available/kanboard
  1. Copy and paste the following block of code inside your new site configuration file:
server {
    listen 80;
    listen [::]:80;
    root                    /var/www/html;
    server_name   ;
    location / {
        proxy_set_header    X-Forwarded-For $remote_addr;
        proxy_set_header    Host $http_host;
        proxy_pass          http://localhost:8080;

Note: replace “” with the actual domain name.

  1. Create a symbolic link for your Kanboard reverse proxy:
sudo ln -s /etc/nginx/sites-available/kanboard /etc/nginx/sites-enabled/kanboard
  1. Reload your Nginx service daemon:
sudo systemctl reload nginx.service

Obtaining an SSL Certificate for Kanboard

With your reverse proxy up, you can now request an SSL certificate for your Kanboard. This section shows you how to obtain a free certificate through the Electronic Frontier Foundation’s (EFF) Certbot.

  1. To begin, you need to install and update your system’s core snap daemon:
sudo snap install core
sudo snap refresh core
  1. Install the certbot snap package:
sudo snap install --classic certbot
  1. Create a symbolic link between the certbot snap binary and your system’s default binary directory:
sudo ln -s /snap/bin/certbot /usr/bin/certbot
  1. Test if certbot is running by using it to register itself to the EFF:
sudo certbot register --agree-tos --email ramces@email.invalid
  1. Generate an SSL certificate for your domain name by running the following command:
sudo certbot

Choose the domain from the entry and it will do its job to generate SSL for your domain.

Logging In and Creating A Kanban Board

You can now use Kanboard for creating and managing Kanban boards. To do that, login to your Kanboard instance by accessing its domain name from a web browser.

  1. Use “admin” as the username and password in the login screen.
  2. Click “New project” to create a public Kanban board.

  1. Provide a name and URL slug for your new board.
  2. Click “Public Access” on the page’s left sidebar.

  1. Click the blue “Enable Public Access” button. This will create an RSS feed and a publicly viewable link that you can share with non-Kanboard users.

Creating a User for Collaborative Kanban Boards

Aside from sharing publicly accessible “view-only” boards, you can also use Kanboard to create collaborative “task” boards between multiple local users.

  1. Click the Admin user’s icon on the page’s upper right corner, then select “User management.”

  1. Click the “New User” link along the page’s upper left sidebar.
  2. This will bring up a small dialog prompt where Kanboard will ask you for the username and password of your new user.

Customizing Your Kanban Board with Plugins

One of the brilliant features of Kanboard is that it provides a framework to extend your board beyond its basic features. This means that you do not need to rely on the developers to include a custom feature for your server.

  1. To add a new plugin, click the Admin user’s icon on the page’s upper right corner, then select “Plugins.”

  1. Click the “Plugin Directory” category on the page’s left sidebar.

  1. Find a plugin that you want to install in your Kanboard server. In my case, I will install “MarkdownPlus” to extend the basic Markdown in my server.

  1. Click “Install”, then refresh the webpage to properly load the plugin in your server.

Frequently Asked Questions

Is it possible to backup the contents of my Kanban board?

Yes. To backup a specific Kanban board, click the gear icon on the board that you want to export then click “Exports.”

This will bring up a small prompt where Kanboard will ask you for a date range that you want to export. Provide a start and end date, then click “Export.”

Is it possible to reset my Kanban board's "locked down" period?

Yes. It is possible to reset a particular user’s locked-out timer in Kanboard. To do this, click the Admin user’s icon on the page’s upper right corner. Next, select the “Users management” item then click the name of the locked-out user. Lastly, go to the “Security” category and click “Unlock this user.”

Is it possible to modify the config.php file inside my Kanboard container?

Yes. However, doing this could potentially ruin the consistency of your Docker image. Instead, the developers of the program suggest that you use the environment variables inside your docker-compose.yml file when configuring the values of your Kanboard instance.
