How to Install Concourse CI on Ubuntu 20.04

Introduction

Before we begin talking about how to install Concourse CI on Ubuntu 20.04, let’s briefly understand- What is Concourse CI?

The Concourse is an open-source CI/CD system with approximately 100 integrations and resource types to the outside world. Concourse reduces the risk of switching to and from Concourse, by encouraging practices that decouple the project from the CI's little details and keep all configuration in declarative files that can be checked into version control.

In this tutorial, you will install Concourse CI on Ubuntu 20.04. We will also address a few FAQs related to the Concourse CI installation on Ubuntu 20.04.

Advantages of Concourse CI

1. Automation: Concourse CI enables automatic build, test, and deployment workflows, streamlining development processes.
2. Scalability: It allows horizontal scaling with distributed workers, accommodating projects of any size.
3. Containerized: Concourse CI runs tasks within isolated containers, ensuring clean and reproducible builds.
4. Visibility: Its web UI provides comprehensive visibility into pipeline status, making it easy to track and debug builds.
5. Flexibility: Concourse CI supports a wide range of platforms and integrates well with popular tools for seamless workflow integration.

Prerequisites

You'll have to make sure to install the following in order to successfully complete this tutorial:

• Install Docker
• Install Docker Compose (if not included in the Docker installation)

Step 1- Install dependencies

Install docker and docker-compose.

sudo apt install docker.io docker-compose -y

Step 2- Deploy Concourse using Docker

sudo su

wget https://concourse-ci.org/docker-compose.yml

docker-compose up -d

You may come across the following issues for Windows AMD. Follow the given steps to resolve it.

Right click Docker instance -> Go to Settings -> Daemon -> Advanced -> Set the "experimental": true -> Restart Docker -> Switch to Linux container and restart the docker.

Step 3- Test Setup

1) You then need to open http://<Instance-IP>:8080 in your browser:

2) To download the fly CLI, click on the operating system you are using, or just use curl to download it:

curl -o fly "http://0.0.0.0:8080/api/v1/cli?arch=amd64&platform=linux"

3) Then, copy fly binary into your path ($PATH), such as /usr/local/bin or ~/bin. Make sure to make it executable. For instance:

sudo mkdir -p /usr/local/bin
sudo mv fly /usr/local/bin
sudo chmod 0755 /usr/local/bin/fly

Step 4- Target Concourse

You need to specify the target API for every fly request so that you get the same result every time.

1) Replace tutorial with a name of your choice:

fly --target tutorial login --concourse-url http://<Instance-IP>:8080 -u admin -p admin
fly --target tutorial sync

2) You can then see the saved target Concourse API in a local file:

cat ~/.flyrc

3) Then you'll see a YAML file with the API, credentials etc:

The fly command will target this Concourse API using fly --target tutorial. This makes reusing commands from shell history much less harmful.

Destroy Concourse

Once you're done with the local Concourse, deployed with the help of docker-compose up, you can use docker-compose down to destroy it.

docker-compose down
