Concourse is a simple and scalable CI/CD system developed under the MIT License. It allows you to automate the building, testing, and deployment of software. In this tutorial, we will explain step-by-step how to install Concourse on an OpenBSD server.
Before proceeding to the installation process, you need to have a few basic requirements:
To install Concourse, we need to install a few dependencies first. OpenBSD has a package manager named pkg_add that makes it easy to install and manage software packages.
To install the necessary dependencies, run the following command:
sudo pkg_add postgresql-server postgresql-client ruby
Concourse needs a PostgreSQL database server to store its configuration and other state information. To install PostgreSQL, run the following command:
sudo rcctl enable postgresql
sudo rcctl start postgresql
After installing PostgreSQL, create a user for Concourse by running the following command:
sudo -i -u _postgresql
createuser concourse
exit
Next, create a database for Concourse by running the following command:
createdb --owner=concourse --encoding=utf8 --locale=en_US.UTF-8 concourse
To install Concourse, download the latest version from the official website at https://concourse-ci.org/download.html.
Extract the downloaded file by running the following command:
tar xvf <concourse-version>.tgz
Next, move the extracted directory to /usr/local/bin by running the following command:
sudo mv <concourse-version> /usr/local/bin/
Set the concourse binary to be executable by running the following command:
sudo chmod +x /usr/local/bin/<concourse-version>/concourse
Finally, set up Concourse by running the following commands:
sudo mkdir -p /etc/concourse
sudo openssl genrsa -out /etc/concourse/tsa_host_key 4096
sudo openssl genrsa -out /etc/concourse/worker_key 4096
sudo openssl rsa -pubout -in /etc/concourse/worker_key -out /etc/concourse/worker_key.pub
To run Concourse, open a terminal and run the following command:
sudo CONCOURSE_EXTERNAL_URL=http://<YOUR SERVER IP>:8080 sudo -E /usr/local/bin/<concourse-version>/concourse web \
--session-signing-key /etc/concourse/session_signing_key \
--tsa-host-key /etc/concourse/tsa_host_key \
--tsa-authorized-keys /etc/concourse/worker_key.pub \
--external-url http://<YOUR SERVER IP>:8080 \
--postgres-data-source postgres://concourse@localhost/concourse?sslmode=disable
This will start the Concourse web interface, which can be accessed via a web browser by visiting http://
To create a pipeline in Concourse, you first need to define a pipeline definition file. The pipeline definition file describes the steps that Concourse should take to build, test, and deploy your software.
Once you have created the pipeline definition file, you can create the pipeline by running the following command:
sudo /usr/local/bin/<concourse-version>/concourse set-pipeline -t <TARGET-NAME> -p <PIPELINE-NAME> -c /path/to/pipeline.yml
Congratulations! You have successfully installed Concourse on your OpenBSD server. You can now use Concourse to automate your software build and deployment process.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
