Install Zuul

Initial Setup

First we’ll create the zuul user and set up some directories it needs. We’ll also install the SSH private key that we previously created during the Nodepool setup.

$ sudo groupadd --system zuul
$ sudo useradd --system zuul --home-dir /var/lib/zuul --create-home -g zuul
$ sudo mkdir /etc/zuul/
$ sudo mkdir /var/log/zuul/
$ sudo chown zuul:zuul /var/log/zuul/
$ sudo mkdir /var/lib/zuul/.ssh
$ sudo chmod 0700 /var/lib/zuul/.ssh
$ sudo mv nodepool_rsa /var/lib/zuul/.ssh
$ sudo chown -R zuul:zuul /var/lib/zuul/.ssh

Installation

Clone the Zuul git repository and install it. The bindep program is used to determine any additional binary dependencies which are required.

# All:
$ git clone https://opendev.org/zuul/zuul
$ pushd zuul/

# For Fedora and CentOS:
$ sudo yum -y install $(bindep -b compile)

# For openSUSE:
$ zypper install -y $(bindep -b compile)

# All:
$ sudo pip3 install .
$ sudo zuul-manage-ansible
$ popd

Service Files

Zuul includes systemd service files for Zuul services in the etc source directory. To use them, do the following steps.

$ sudo cp etc/zuul-scheduler.service /etc/systemd/system/zuul-scheduler.service
$ sudo cp etc/zuul-executor.service /etc/systemd/system/zuul-executor.service
$ sudo cp etc/zuul-web.service /etc/systemd/system/zuul-web.service
$ sudo chmod 0644 /etc/systemd/system/zuul-scheduler.service
$ sudo chmod 0644 /etc/systemd/system/zuul-executor.service
$ sudo chmod 0644 /etc/systemd/system/zuul-web.service

If you are installing Zuul on CentOS 7 and copied the provided service files in previous step, please follow the steps below to use corresponding systemd drop-in files so Zuul services can be managed by systemd.

$ sudo mkdir /etc/systemd/system/zuul-scheduler.service.d
$ sudo cp etc/zuul-scheduler.service.d/centos.conf \
    /etc/systemd/system/zuul-scheduler.service.d/centos.conf
$ sudo chmod 0644 /etc/systemd/system/zuul-scheduler.service.d/centos.conf
$ sudo mkdir /etc/systemd/system/zuul-executor.service.d
$ sudo cp etc/zuul-executor.service.d/centos.conf \
    /etc/systemd/system/zuul-executor.service.d/centos.conf
$ sudo chmod 0644 /etc/systemd/system/zuul-executor.service.d/centos.conf
$ sudo mkdir /etc/systemd/system/zuul-web.service.d
$ sudo cp etc/zuul-web.service.d/centos.conf \
    /etc/systemd/system/zuul-web.service.d/centos.conf
$ sudo chmod 0644 /etc/systemd/system/zuul-web.service.d/centos.conf
