Zuul From Scratch

Note

This is a work in progress that attempts to walk through all of the steps needed to run Zuul on a all-in-one server, and demonstrate running against either a GitHub or Gerrit project.

Environment Setup

Follow the instructions below, depending on your server type.

fedora27_setup

centos7_setup

opensuse_leap15_setup

Installation

nodepool_install

zuul_install

Configuration

Nodepool

Nodepool can support different backends. Select the configuration for your installation.

nodepool_openstack

nodepool_static

Zuul

Write the Zuul config file. Note that this configures Zuul's web server to listen on all public addresses. This is so that Zuul may receive webhook events from GitHub. You may wish to proxy this or further restrict public access.

sudo bash -c "cat > /etc/zuul/zuul.conf <<EOF
[gearman]
server=127.0.0.1

[gearman_server]
start=true

[executor]
private_key_file=/var/lib/zuul/.ssh/nodepool_rsa

[web]
listen_address=0.0.0.0

[scheduler]
tenant_config=/etc/zuul/main.yaml
EOF"

sudo bash -c "cat > /etc/zuul/main.yaml <<EOF
- tenant:
    name: quickstart
EOF"

Starting Services

After you have Zookeeper, Nodepool, and Zuul installed and configured, you can start Nodepool and Zuul services with:

sudo systemctl daemon-reload

sudo systemctl start nodepool-launcher.service
sudo systemctl status nodepool-launcher.service
sudo systemctl enable nodepool-launcher.service

sudo systemctl start zuul-scheduler.service
sudo systemctl status zuul-scheduler.service
sudo systemctl enable zuul-scheduler.service
sudo systemctl start zuul-executor.service
sudo systemctl status zuul-executor.service
sudo systemctl enable zuul-executor.service
sudo systemctl start zuul-web.service
sudo systemctl status zuul-web.service
sudo systemctl enable zuul-web.service

Use Zuul Jobs

Zuul provides a standard library of jobs and roles. To take advantage of these jobs, add the zuul-jobs repo, which is hosted by the Zuul project, to your system.

Add to /etc/zuul/zuul.conf:

sudo bash -c "cat >> /etc/zuul/zuul.conf <<EOF

[connection zuul-git]
driver=git
baseurl=https://git.zuul-ci.org/
EOF"

Restart executor and scheduler:

sudo systemctl restart zuul-executor.service
sudo systemctl restart zuul-scheduler.service

Setup Your Repo

Select your code repository to setup.

gerrit_setup
