How to Install Concourse on Void Linux

Concourse is an open-source continuous integration and delivery platform. In this tutorial, we will show you how to install Concourse on Void Linux.

Prerequisites

Before you start, make sure you have the following prerequisites:

A running instance of Void Linux
A non-root user with sudo access

Step 1: Install Dependencies

Concourse requires several dependencies to function properly, so let's install them first.

To install these dependencies, run the following command:

sudo xbps-install -S curl git bash postgresql

Step 2: Install Concourse

Now let's download and install Concourse on Void Linux.

Download the Concourse binary:
```
curl -LO https://github.com/concourse/concourse/releases/download/v7.1.0/concourse-7.1.0-linux-amd64.tgz
```
Note: Make sure you're downloading the latest version by checking the Concourse releases page.

Extract the Concourse binary:

tar xvzf concourse-7.1.0-linux-amd64.tgz

Move the concourse binary to /usr/local/bin:
```
sudo mv concourse /usr/local/bin
```
Verify that Concourse is working by running:
```
concourse --version
```
This command should output the Concourse version number.

Step 3: Configure PostgreSQL

Concourse requires a PostgreSQL database to store data. Let's set up PostgreSQL next.

Install the postgresql-contrib package:

sudo xbps-install -S postgresql-contrib

Start the PostgreSQL service:

sudo ln -s /etc/sv/postgresql /var/service/

Create a new PostgreSQL database:

sudo su - postgres
psql
CREATE DATABASE concourse;

Create a new PostgreSQL user:

CREATE USER concourse WITH ENCRYPTED PASSWORD 'my_password';
GRANT ALL PRIVILEGES ON DATABASE concourse TO concourse;

Note: Replace my_password with a secure password for the concourse user.

Exit the PostgreSQL console:
```
\q
exit
```

Step 4: Start Concourse

Now it's time to start Concourse:

Create a Concourse configuration file:

mkdir concourse
cd concourse
vi concourse.yml

Enter the following configuration in the concourse.yml file:

---
postgresql:
  database: concourse
  role: concourse
  password: my_password
  host: localhost

web:
  external_url: http://localhost:8080
  auth:
    main_team:
      basic_auth:
        username: my_user
        password: my_password
      local_user:
        username: my_user2
        password: my_password2

Note: Replace my_password with the password you set for the concourse user in Step 3, and replace my_user and my_user2 with your own usernames and passwords.

Start the Concourse web server:
```
concourse web -c concourse.yml
```
Open a web browser and navigate to http://localhost:8080 to access the Concourse dashboard.

Conclusion

You now have Concourse installed on Void Linux. With Concourse, you can easily automate your continuous integration and delivery pipelines.
