Introduction
Before we begin talking about how to install Concourse CI on Ubuntu 22.04, 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 22.04. We will also address a few FAQs related to the Concourse CI installation on Ubuntu 22.04.
Advantages of Concourse CI

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
CONCOURSE_EXTERNAL_URL
value inside docker-compose.yml
file to set use your public IP address.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://127.0.0.1:8080/
in your browser:
![Concourse Welcome Page](https://vegastack.com/tutorials/content/images/2020/10/Concourse-Welcome-Page.png)
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://127.0.0.1:8080 -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:
targets:

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
