Install Nodepool

Initial Setup

First we’ll create the nodepool user and set up some directories it needs. We also need to create an SSH key for Zuul to use when it logs into the nodes that Nodepool provides.

$ sudo adduser --system nodepool --home-dir /var/lib/nodepool --create-home
$ ssh-keygen -t rsa -b 2048 -f nodepool_rsa  # don't enter a passphrase
$ sudo mkdir /etc/nodepool/
$ sudo mkdir /var/log/nodepool
$ sudo chgrp -R nodepool /var/log/nodepool/
$ sudo chmod 775 /var/log/nodepool/

Installation

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

$ git clone https://git.zuul-ci.org/nodepool
$ cd nodepool/
$ sudo yum -y install $(bindep -b)
$ sudo pip3 install .

Service File

Nodepool includes a systemd service file for nodepool-launcher in the etc source directory. To use it, do the following steps.

$ sudo cp etc/nodepool-launcher.service /etc/systemd/system/nodepool-launcher.service
$ sudo chmod 0644 /etc/systemd/system/nodepool-launcher.service

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

$ sudo mkdir /etc/systemd/system/nodepool-launcher.service.d
$ sudo cp etc/nodepool-launcher.service.d/centos.conf \
     /etc/systemd/system/nodepool-launcher.service.d/centos.conf
$ sudo chmod 0644 /etc/systemd/system/nodepool-launcher.service.d/centos.conf
