How to Install Concourse on Arch Linux

Concourse is an open-source continuous integration and deployment tool that helps you automate your development processes. In this tutorial, we will guide you through the installation process of Concourse on Arch Linux.

Prerequisites

Before installing Concourse, ensure your system has the following prerequisites:

• Arch Linux installed
• Basic knowledge of running commands in the Linux terminal
• Administrative access to the system

Step 1: Install Dependencies

Concourse requires several dependencies to be installed on your system. These include:

• PostgreSQL
• Ruby
• Ruby Gems
• Docker

You can install these by running the following command in terminal:

$ sudo pacman -S postgresql ruby rubygems docker

Step 2: Install Fly CLI

The fly CLI tool is used to interact with Concourse in order to execute pipelines. You can install fly by running the following command:

$ sudo pacman -S concourse-fly

Step 3: Install Concourse

Concourse can be installed on Arch Linux using the official Concourse binary. Follow the instructions below to download and install Concourse:

1. Download the Concourse binary:

   $ wget https://github.com/concourse/concourse/releases/download/v7.0.0/concourse-7.0.0-linux-amd64.tgz -O concourse.tgz
   

2. Extract the Concourse binary:

   $ tar -xvf concourse.tgz -C /usr/local/bin
   

3. Set the correct permissions:

   $ sudo chmod +x /usr/local/bin/concourse*
   

Step 4: Create Database and User for Concourse

Concourse requires a PostgreSQL database to store its data. Follow the instructions below to create a database and user for Concourse:

1. Start the PostgreSQL service:

   $ sudo systemctl start postgresql
   

2. Create a new PostgreSQL user:

   $ sudo -u postgres createuser concourse -s
   

3. Create a new PostgreSQL database:

   $ sudo -u postgres createdb --owner=concourse atc
   

Step 5: Configure Concourse

Concourse needs to be configured with your system settings to operate correctly. Follow the instructions below to configure Concourse:

1. Create a Concourse configuration file:

   $ sudo mkdir /etc/concourse
   $ sudo vim /etc/concourse/main.yml
   

2. Copy and paste the following configuration into the file:

   ---
   postgresql_data_source: postgres://concourse@localhost/atc?sslmode=disable
   basic_auth_username: some-username
   basic_auth_password: some-password
   main_team_name: main
   external_url: http://<your-concourse-host-ip>:8080
   

   Replace <your-concourse-host-ip> with your system's IP address.

Step 6: Run Concourse

Now that everything is set up, you can run Concourse by executing the following command:

$ sudo concourse web

You should now be able to access Concourse by typing http://<your-concourse-host-ip>:8080 into a web browser.
