How to Install Concourse on OpenSUSE Latest

Concourse is an open-source continuous integration and delivery system that can be used to automate testing and deployment of software. In this tutorial, we will guide you through the process of installing Concourse on OpenSUSE Latest.

Prerequisites

Before we get started with the installation of Concourse, make sure you have the following prerequisites:

OpenSUSE Latest installed on your system.
A user account with sudo privileges.
A working internet connection.

Step 1: Install Docker

Concourse uses Docker containers to run various components, so we need to install Docker on our system before we can proceed with the installation of Concourse.

Open a terminal window and enter the following command to update the packages index:
```
sudo zypper refresh
```
Install Docker by running this command:
```
sudo zypper install docker
```
During the installation, you may be prompted to add your regular user account to the docker group. If so, enter the following command to add it:
```
sudo usermod -aG docker $USER
```
Start and enable the Docker service by running these commands:
```
sudo systemctl start docker
sudo systemctl enable docker
```

Now, verify that Docker is installed and working by running this command:

docker version

If you see output similar to the following, it means that Docker is installed and working:

Step 2: Install Concourse

With Docker installed and working, we can proceed with the installation of Concourse.

First, create a directory for Concourse by running this command:
```
sudo mkdir /opt/concourse
```
Change the ownership of the directory to the current user by running:
```
sudo chown -R $USER:$USER /opt/concourse
```
Download the Concourse binary by running:
```
wget https://github.com/concourse/concourse/releases/download/v7.5.0/concourse-7.5.0-linux-amd64.tgz -P /opt/concourse
```
Make sure to replace v7.5.0 with the latest version of Concourse. You can find the latest version on the Concourse release page.

Unpack the Concourse binary by running:

sudo tar -C /opt/concourse -xvzf /opt/concourse/concourse-7.5.0-linux-amd64.tgz

Link the fly binary by running:

sudo ln -s /opt/concourse/fly /usr/local/bin/fly

Verify that Concourse is installed by running:
```
fly --version
```
You should see output similar to the following:
```
fly version 7.5.0
```

Step 3: Configure Concourse

Now that Concourse is installed, we need to configure it to run on our system.

Create a directory to store the Concourse configuration by running:
```
sudo mkdir /etc/concourse
```
Change the ownership of the directory to the current user by running:
```
sudo chown -R $USER:$USER /etc/concourse
```
Create a concourse.yml file by running:
```
touch /etc/concourse/concourse.yml
```

Open the concourse.yml file in a text editor and add the following configuration:

ground_station:
  listen_addr: 127.0.0.1:7778
  peer_addr: 127.0.0.1:7779
web:
  external_url: http://<your-ip>:8080
  auth_duration: 24h
  auth_username: admin
  auth_password: <your-password>
  auth_main_team_name: main
main_team:
  basic_auth_username: admin
  basic_auth_password: <your-password>
  owner: local
runner:
  garden:
    garden_addr: /var/run/garden
  baggageclaim:
    driver: btrfs
    volumes:
      - /var/volumes

Make sure to replace <your-ip> and <your-password> with your IP address and preferred password.

Save and close the file.

Step 4: Start Concourse

With Concourse configured, we can start it and verify that it's working.

Start Concourse by running:

/opt/concourse/bin/concourse worker --config /etc/concourse/concourse.yml &

Verify that Concourse is running by visiting http://<your-ip>:8080 in a web browser. You should see the Concourse login page.
Log in using the auth_username and auth_password credentials specified in the concourse.yml file.

Once logged in, you should see the Concourse dashboard, which will allow you to create and manage pipelines.

Conclusion

Congratulations! You have successfully installed Concourse on OpenSUSE Latest. You can now create and manage pipelines to automate your testing and deployment workflows.
