How to Install Kallithea on Alpine Linux

In this tutorial, we will go through the steps on how to install Kallithea on Alpine Linux. Kallithea is a free and open-source source control management system written in Python. It provides support for Mercurial and Git repositories and has a user-friendly interface.

Prerequisites

Before installing Kallithea, you need to have the following:

• A server running Alpine Linux
• Root access to the server
• A web server installed on the server (we will be using nginx)
• Python 3 installed
• Git and Mercurial installed

Step 1: Update your packages

The first step is to update your package repositories and packages to ensure that you have the latest versions:

sudo apk update
sudo apk upgrade

Step 2: Install Dependencies

Next, we will install the dependencies required by Kallithea:

sudo apk add --no-cache gcc python3-dev musl-dev postgresql-dev git mercurial

Step 3: Install Kallithea

We will now proceed to install Kallithea using pip3:

sudo pip3 install kallithea

Step 4: Configure Kallithea

In this step, we will create a configuration file for Kallithea. Change the directory to the location where you want to place your Kallithea configuration file and create a new file named kallithea.ini.

cd /etc/kallithea
sudo touch kallithea.ini

Open the file using your preferred text editor and add the following contents:

[server:main]
use = egg:gunicorn
host = 127.0.0.1
port = 5000
workers = 2

[app:main]
use = egg:kallithea
kallithea.config_file = %(here)s/kallithea.ini
kallithea.config_module = %(here)s/config.ini

Save the file and exit the text editor.

Step 5: Configure Nginx

We will now configure Nginx to serve Kallithea. Create a new server block for Kallithea in the Nginx configuration file:

sudo nano /etc/nginx/conf.d/kallithea.conf

Add the following contents to the file:

server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://127.0.0.1:5000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;    
    }
}

Save the file and exit the text editor.

Step 6: Start Kallithea

We will now start Kallithea using the gunicorn server:

sudo kallithea-paster serve kallithea.ini

The Kallithea server will now start running. You should be able to access it by visiting http://example.com on your web browser.

Conclusion

You have successfully installed Kallithea on Alpine Linux and configured it to work with Nginx. You can now start managing your Git and Mercurial repositories using Kallithea.
